EXPENSE EXAMPLE

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 17.00%
Strategy [Heading] rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal conditions, the fund invests at least 80% of its net assets in domestic equity securities.

The manager seeks to identify companies that it believes are currently undervalued relative to the market, based on estimated future earnings and cash flow. These companies generally have market values at valuation ratios, such as price to book, below the market average defined by the S&P 500 Index.

In choosing individual securities, the manager screens a dynamic universe of the 500 largest publicly traded U.S. companies. (As of December 31, 2015, those with market values above approximately $3.9 billion.) The manager uses fundamental research and proprietary modeling to rank these companies from the cheapest to the most expensive based on current share price relative to estimated long-term earnings power. Focusing on the cheapest-ranked companies, the manager constructs a portfolio of stocks of companies it believes generally have current earnings below normal levels, a sound plan to restore earnings to normal, and a sustainable business advantage.

This systematic process is intended to ensure that the fund's portfolio avoids the emotional inputs that can lead to overvalued securities. The manager generally sells a security when it reaches fair value, there are more attractive opportunities, or there is a change in company fundamentals.

Under normal market conditions, the fund will be almost entirely invested in stocks. The fund may invest up to 20% of its net assets in debt securities, including those rated below investment-grade (below Baa by Moody's Investors Service, Inc. or below BBB by Standard & Poor's Ratings Services or unrated equivalents) (i.e., junk bonds). The fund's investment policies are based on credit ratings at the time of purchase.

The fund may also invest up to 20% of its net assets in securities of foreign issuers that are not publicly traded in the United States, including depositary receipts. The fund may invest without regard to the 20% limitation in securities of foreign issuers that are listed and traded on a domestic national securities exchange. The fund may focus on particular sectors of the economy.
Risk [Heading] rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.

During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.

The fund's main risks are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

Credit and counterparty risk. The issuer or guarantor of a fixed-income security or a borrower of fund securities may not make timely payments or otherwise honor its obligations.

Cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance.

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.

Equity securities risk. The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential, and in certain markets value stocks may underperform the market as a whole.

Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.

Foreign securities risk. Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.

Large company risk. Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.

Liquidity risk. The extent to which a security may be sold or a derivative position closed without negatively impacting its market value, if at all, may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.

Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.

Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.

PAST PERFORMANCE

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291, Monday to Thursday, 8:00 A.M.—7:00 P.M., and Friday, 8:00 A.M.—6:00 P.M., Eastern time (Class A, Class B and Class C), or 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days (Class I and Class R suite).

A note on performance

Class A, Class R6, and Class R2 shares commenced operations on June 24, 1996, September 1, 2011, and March 1, 2012, respectively; Class R3, Class R4, and Class R5 shares commenced operations on May 22, 2009. Returns shown prior to these classes' commencement dates are those of Class A shares that have been recalculated to reflect the gross fees and expenses of the applicable class. Returns for Class R2, Class R3, Class R4, Class R5, and Class R6 shares would have been substantially similar to returns of Class A shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.

EXPENSE EXAMPLE

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 30% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 30.00%
Strategy [Heading] rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, at least 80% of the fund's net assets (plus any borrowings for investment purposes) will be invested in common stocks of companies the subadvisor regards as U.S. Global Leaders.

The manager considers U.S. Global Leaders to be U.S. companies with multinational operations that typically exhibit the following key sustainable growth characteristics: (i) hold leading market shares of their relevant industries that result in higher profit margins and high investment returns; and (ii) supply consumable products or services so that their revenue streams are recurring.

The manager seeks to identify companies with superior long-term earnings prospects and will hold them as long as the manager believes they are not overvalued and their prospects for capital growth remain favorable. As a result of its investment strategy, the fund typically invests in large-capitalization companies (companies in the capitalization range of the S&P 500 Index, $4 billion to $530 billion as of December 31, 2015).

The fund is non-diversified, which allows it to focus its assets in a smaller number of issuers than a diversified fund and make larger investments in individual companies. The fund may focus on a particular sector or sectors of the economy.

The fund may invest in other types of equity securities, including up to 20% of its net assets in foreign companies and in U.S.-traded securities of large-capitalization, well-established foreign issuers.
Risk [Heading] rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.

During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.

The fund's main risks are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

Cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance.

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.

Equity securities risk. The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.

Foreign securities risk. Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.

Large company risk. Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.

Non-diversified risk. Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.

Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Non-diversified risk. Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.

PAST PERFORMANCE

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. The Russell 1000 Growth Index shows how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291, Monday to Thursday, 8:00 A.M.—7:00 P.M., and Friday, 8:00 A.M.—6:00 P.M., Eastern time (Class A, Class B and Class C), or 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days (Class I, Class R2, and Class R6).

A note on performance

Class A, Class R6, and Class R2 shares commenced operations on September 29, 1995, September 1, 2011, and March 1, 2012, respectively. Returns shown prior to these classes' commencement dates are those of Class A shares that have been recalculated to reflect the gross fees and expenses of the applicable class. Returns for Class R2 and Class R6 shares would have been substantially similar to returns of Class A shares because each class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.
