对于使用java 8向前的程序员，可以使用下面的代码来使用显式等待等待页面加载。

JavascriptExecutor js = (JavascriptExecutor) driver;  
new WebDriverWait(driver, 10).until(webDriver ->
(js).executeScript("return document.readyState;").equals("complete"));

注意:在我上面的代码中使用Lambda表达式，它只在java 8的后续版本中可用。

对于使用低版本Java(即Java 8以下)的程序员，可以使用:

ExpectedCondition<Boolean> cond = new ExpectedCondition<Boolean>() {
    @Override
    public Boolean apply(WebDriver input) {
        JavascriptExecutor js = (JavascriptExecutor) driver; 
        return js.executeScript("return document.readyState;").equals("complete");
            }
        };
         
    new WebDriverWait(driver, 100).until(cond);

在Webdriver/Selenium 2软件测试工具中有两种类型的等待。一种是隐式等待，另一种是显式等待。两者(隐式等待和显式等待)在WebDriver中都很有用。使用等待，我们告诉WebDriver在进入下一步之前等待一定的时间。可以使用隐式等待来等待页面加载。

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

如果有人使用硒化物:

public static final Long SHORT_WAIT = 5000L; // 5 seconds
$("some_css_selector").waitUntil(Condition.appear, SHORT_WAIT);

更多条件可以在这里找到: http://selenide.org/javadoc/3.0/com/codeborne/selenide/Condition.html

最简单的方法就是等待一些元素出现在加载页面上。

如果你想在页面加载后点击一些按钮，你可以使用等待，然后点击:

await().until().at.most(20, TimeUnit.Seconds).some_element.isDisplayed(); // or another condition
getDriver().find(some_element).click;

The best way to wait for page loads when using the Java bindings for WebDriver is to use the Page Object design pattern with PageFactory. This allows you to utilize the AjaxElementLocatorFactory which to put it simply acts as a global wait for all of your elements. It has limitations on elements such as drop-boxes or complex javascript transitions but it will drastically reduce the amount of code needed and speed up test times. A good example can be found in this blogpost. Basic understanding of Core Java is assumed.

http://startingwithseleniumwebdriver.blogspot.ro/2015/02/wait-in-page-factory.html

/**
 * Call this method before an event that will change the page.
 */
private void beforePageLoad() {
    JavascriptExecutor js = (JavascriptExecutor) driver;
    js.executeScript("document.mpPageReloaded='notYet';");
}

/**
 * Call this method after an event that will change the page.
 * 
 * @see #beforePageLoad
 * 
 *      Waits for the previous page to disappear.
 */
private void afterPageLoad() throws Exception {
    (new WebDriverWait(driver, 10)).until(new Predicate<WebDriver>() {

        @Override
        public boolean apply(WebDriver driver) {
            JavascriptExecutor js = (JavascriptExecutor) driver;
            Object obj = js.executeScript("return document.mpPageReloaded;");
            if (obj == null) {
                return true;
            }
            String str = (String) obj;
            if (!str.equals("notYet")) {
                return true;
            }
            return false;
        }
    });
}

在只更改部分文档的情况下，您可以从文档更改为元素。

这个技巧的灵感来自于sincebasic的答案。
