Ruby实现:

wait = Selenium::WebDriver::Wait.new(:timeout => 10)
wait.until {
    @driver.execute_script("return document.readyState;") == "complete" 
}

这段代码将等待页面上的所有元素都加载到DOM中。

WebDriver driver = new WebDriver();
WebDriverWait wait = new WebDriverWait(driver, timeout);

wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*")));

/**
 * 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。

你也可以使用类:ExpectedConditions来显式地等待一个元素出现在网页上，然后你才能采取任何行动

你可以使用ExpectedConditions类来确定一个元素是否可见:

WebElement element = (new WebDriverWait(getDriver(), 10)).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("input#houseName")));

查看ExpectedConditions类Javadoc，了解您可以检查的所有条件的列表。

Imran对Java 7的回答是:

    WebDriverWait wait = new WebDriverWait(driver, 30);

    wait.until(new ExpectedCondition<Boolean>() {
        public Boolean apply(WebDriver wdriver) {
            return ((JavascriptExecutor) driver).executeScript(
                "return document.readyState"
            ).equals("complete");
        }
    });

你可以使用下面的代码片段来加载页面:

    IWait wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver,TimeSpan.FromSeconds(30.00));
    wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));

或者你可以使用waiter的任何元素被加载，并成为可见/可点击的页面上，最有可能的是，这将是在加载结束时加载，如:

    Wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath(xpathOfElement));
    var element = GlobalDriver.FindElement(By.XPath(xpathOfElement));
    var isSucceededed = element != null;
