J汤html解析样式＝“;显示:无;不要显示链接

当您在浏览器中检查元素时，您会在javascript运行后得到DOM。Jsoup是一个解析器，因此您可以在运行任何javascript之前获得html。如果你想检查Jsoup将获取的实际html，请按Ctrl+U并使用chrome（我认为这与mozilla相同）。这是在没有任何javascript修改内容的情况下从服务器获得的html响应。

考虑到以上内容，href属性正在被一些javascript代码修改。Jsoup无法处理此问题，因为它无法执行javascript。您必须找到修改href属性的javascript代码，并使用java的ScriptEngine或可以处理诸如Selenium之类的javascript执行的解析器来执行它。

如果你分享你试图解析的页面的链接，我可以提供更多帮助。

有了这个，你就不用再使用Jsoup了。如果HtmlUnit不适合您作为解析器的需要只需使用它来获得完整的html（在执行js之后），然后用Jsoup解析它并执行从那里。你必须下载HtmlUnit。在类路径中包含jar，或者使用maven。

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class Main {
    public static void main(String[] args) throws Exception {
        final WebClient webClient = new WebClient();
        final HtmlPage page = webClient.getPage("http://www.mp3juices.cc/download/sEhy-RXkNo0/mp3/rihanna_-_man_down/");
        webClient.closeAllWindows();
        System.out.println(page.getElementById("download_link", false).getAttribute("href"));
    }
}

更新

根据这一点，HtmlUnit有许多依赖项，这使得它运行起来非常麻烦在Android上。更好的解决方案可以在这里和这里找到
