本文整理了Java中com.gargoylesoftware.htmlunit.WebClient.waitForBackgroundJavaScript()方法的一些代码示例，展示了WebClient.waitForBackgroundJavaScript()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。WebClient.waitForBackgroundJavaScript()方法的具体详情如下：
包路径：com.gargoylesoftware.htmlunit.WebClient
类名称：WebClient
方法名：waitForBackgroundJavaScript

WebClient.waitForBackgroundJavaScript介绍

[英]Experimental API: May be changed in next release and may not yet work perfectly!

This method blocks until all background JavaScript tasks have finished executing. Background JavaScript tasks are JavaScript tasks scheduled for execution via window.setTimeout, window.setInterval or asynchronous XMLHttpRequest.

If a job is scheduled to begin executing after (now + timeoutMillis), this method will wait for timeoutMillis milliseconds and then return a value greater than 0. This method will never block longer than timeoutMillis milliseconds.

Use this method instead of #waitForBackgroundJavaScriptStartingBefore(long) if you don't know when your background JavaScript is supposed to start executing, but you're fairly sure that you know how long it should take to finish executing.
[中]实验API：可能会在下一个版本中更改，可能还不能完美工作！
此方法会一直阻塞，直到所有后台JavaScript任务都完成执行。后台JavaScript任务是计划通过Windows执行的JavaScript任务。设定超时，窗口。setInterval或异步XMLHttpRequest。
如果作业计划在（现在+timeoutMillis）之后开始执行，此方法将等待timeoutMillis毫秒，然后返回大于0的值。此方法的阻止时间永远不会超过timeoutMillis毫秒。
如果你不知道背景JavaScript应该在什么时候开始执行，但是你很确定你知道需要多长时间才能完成，那么就用这个方法代替#waitForBackgroundJavaScriptStartingBefore（long）。
