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 the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 47% of the average value of its portfolio.

It assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year, that the Fund's operating expenses remain the same (except that fee waivers or reimbursements, if any, are only reflected in the 1-Year figures) and that all dividends and distributions are reinvested. Your actual costs may be higher or lower.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund normally invests at least 80% of its investable assets in equity and equity-related securities. The term “investable assets” refers to the Fund's net assets plus any borrowings for investment purposes. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions.The Fund may invest in securities of issuers of any market capitalization. In deciding which securities to buy, the Fund's portfolio managers use a blend of investment styles. That is, they invest in equity and equity-related securities from traditionally growth and value areas, as well as stocks exhibiting characteristics of both. The Fund's portfolio managers use quantitative analytics to complement their fundamental investment process, and to provide additional investment insights on which to make investment decisions from time to time.In addition to common stock, the equity-related securities that the Fund may invest in include, but are not limited to nonconvertible preferred stock; warrants and rights that can be converted into or exchanged for common stock or the cash value of common stock; investments in various types of businesses, including partnerships and business development companies; securities of real estate investment trusts (“REITs”); American Depositary Receipts (“ADRs”); American Depositary Shares (“ADSs”); and similar securities. The Fund may also buy convertible securities. These are securities—like bonds, corporate notes and preferred stock—that the Fund can convert into common stock of the issuer, the cash value of the issuer’s common stock or some other equity security. The Fund may invest up to 35% of its total assets in non-U.S. securities. At times, the Fund may have a significant portion of its assets invested in the same economic sector.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
PGIM Jennison Blend Fund | Risk Not Insured Depository Institution [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; and is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
PGIM Jennison Blend Fund | Blend Style Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Blend Style Risk. The Fund's blend investment style may subject the Fund to risks of both value and growth investing. The portion of the Fund's portfolio that makes investments pursuant to a growth strategy may be subject to above-average fluctuations as a result of seeking higher than average capital growth. The portion of the Fund's portfolio that makes investments pursuant to a value strategy may be subject to the risk that the market may not recognize a security's intrinsic value for long periods of time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. Issuers of value stocks may have experienced adverse business developments or may be subject to special risks that have caused the stock to be out of favor. If the Fund’s assessment of market conditions or a company’s value is inaccurate, the Fund could suffer losses or produce poor performance relative to other funds. Historically, growth stocks have performed best during later stages of economic expansion and value stocks have performed best during periods of economic recovery. Therefore, both styles may over time go in and out of favor with the markets. At times when a style is out of favor, that portion of the portfolio may lag the other portion of the portfolio, which may cause the Fund to underperform the market in general, its benchmark and other mutual funds. Growth and value stocks have historically produced similar long-term results, though each category has periods when it outperforms the other.
PGIM Jennison Blend Fund | Economic And Market Events Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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 or the functioning of the securities markets, or otherwise reduce inflation, may at times result in unusually high market volatility, which could negatively impact performance. Governmental efforts to curb inflation often have negative effects on the level of economic activity. Relatively reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.
PGIM Jennison Blend Fund | Equity And Equity Related Securities Risks [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Equity and Equity-Related Securities Risk. Equity and equity-related securities may be subject to changes in value, and their values may be more volatile than those of other asset classes. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.
PGIM Jennison Blend Fund | Foreign Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign Securities Risk. Investments in securities of non-U.S. issuers (including those denominated in U.S. dollars) may involve more risk than investing in securities of U.S. issuers. Foreign political, economic and legal systems, especially those in developing and emerging market countries, may be less stable and more volatile than in the United States. Foreign legal systems generally have fewer regulatory requirements than the U.S. legal system, particularly those of emerging markets. In general, less information is publicly available with respect to non-U.S. companies than U.S. companies. Non-U.S. companies generally are not subject to the same accounting, auditing, and financial reporting standards as are U.S. companies. Additionally, the changing value of foreign currencies and changes in exchange rates could also affect the value of the assets the Fund holds and the Fund's performance. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. Investments in emerging markets are subject to greater volatility and price declines.In addition, the Fund's investments in non-U.S. securities may be subject to the risks of nationalization or expropriation of assets, imposition of currency exchange controls or restrictions on the repatriation of non-U.S. currency, confiscatory taxation and adverse diplomatic developments. Special U.S. tax considerations may apply.
PGIM Jennison Blend Fund | Increase In Expenses Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Increase in Expenses Risk. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Active and frequent trading of Fund securities can increase expenses.
PGIM Jennison Blend Fund | Large Shareholder And Large Scale Redemption Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Large Shareholder and Large Scale Redemption Risk. Certain individuals, accounts, funds (including funds affiliated with the Manager) or institutions, including the Manager and its affiliates, may from time to time own or control a substantial amount of the Fund’s shares. There is no requirement that these entities maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy. The Fund’s ability to pursue its investment objective after one or more large scale redemptions may be impaired and, as a result, the Fund may invest a larger portion of its assets in cash or cash equivalents.
PGIM Jennison Blend Fund | Management Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Management Risk. Actively managed funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but the subadviser's judgments about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements may be incorrect. Additionally, the investments selected for the Fund may underperform the markets in general, the Fund's benchmark and other funds with similar investment objectives.
PGIM Jennison Blend Fund | Market Capitalization Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Capitalization Risk. The Fund may invest in companies of any market capitalization. Generally, the stock prices of small- and mid-cap companies are less stable than the prices of large-cap stocks and may present greater risks. Large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform compared to investments that focus on smaller capitalized companies.
PGIM Jennison Blend Fund | Market Disruption And Geopolitical Risks [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Disruption and Geopolitical Risks. Market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including Russia’s military invasion of Ukraineand the Israel-Hamas war), geopolitical developments (including trading and tariff arrangements, sanctions and cybersecurity attacks), instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally).The extent and duration of such events and resulting market disruptions cannot be predicted, but could be substantial and could magnify the impact of other risks to the Fund. These and other similar events could adversely affect the U.S. and foreign financial markets and lead to increased market volatility, reduced liquidity in the securities markets, significant negative impacts on issuers and the markets for certain securities and commodities and/or government intervention. They may also cause short- or long-term economic uncertainties in the United States and worldwide. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively impacted. Further, due to closures of certain markets and restrictions on trading certain securities, the value of certain securities held by the Fund could be significantly impacted, which could lead to such securities being valued at zero.
PGIM Jennison Blend Fund | Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.
PGIM Jennison Blend Fund | Sector Exposure Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Sector Exposure Risk. At times, the Fund may have a significant portion of its assets invested in the same economic sector, such as the information technology and financials sectors. Issuers in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.
PGIM Jennison Blend Fund | Small And Medium Sized Company Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Small and Medium Sized Companies Risk. Small and medium sized companies usually offer a smaller range of products and services than larger companies. Smaller companies may also have limited financial resources and may lack management depth. As a result, their prices may fluctuate more than the stocks of larger, more established companies. Historically, small and medium sized companies have sometimes gone through extended periods when they did not perform as well as larger companies. Small and medium sized companies generally are more illiquid than larger companies, which may make such investments more difficult to sell at the time and price that the Fund would like.

[1] Investors who purchase $1 million or more of Class A shares and sell these shares within 12 months of purchase are also subject to a contingent deferred sales charge (“CDSC”) of 1.00%, although they are not subject to an initial sales charge. The CDSC is waived for certain retirement and/or benefit plans.

[2] PGIM Investments LLC (“PGIM Investments”) has contractually agreed, through December 31, 2025, to limit Total Annual Fund Operating Expenses after fee waivers and/or expense reimbursements to 0.68% of average daily net assets for Class R6 shares. This contractual waiver excludes interest, brokerage, taxes (such as income and foreign withholding taxes, stamp duty and deferred tax expenses), acquired fund fees and expenses, extraordinary expenses, and certain other Fund expenses such as dividend and interest expense and broker charges on short sales. Where applicable, PGIM Investments agrees to waive management fees or shared operating expenses on any share class to the same extent that it waives such expenses on any other share class. In addition, Total Annual Fund Operating Expenses for Class R6 shares will not exceed Total Annual Fund Operating Expenses for Class Z shares. Fees and/or expenses waived and/or reimbursed by PGIM Investments for the purpose of preventing the expenses from exceeding a certain expense ratio limit may be recouped by PGIM Investments within the same fiscal year during which such waiver and/or reimbursement is made if such recoupment can be realized without exceeding the expense limit in effect at the time of the waiver/reimbursement and/or recoupment for that fiscal year, as applicable. This waiver may not be terminated prior to December 31, 2025 without the prior approval of the Fund’s Board of Directors.

[3] Class C shares are sold with a CDSC of 1.00% on sales made within 12 months of purchase.

[4] Direct Transfer Agent Accounts holding under $10,000 of Class Z shares are subject to the $15 fee.
