我使用node + selenium-webdriver(现在的版本是3.5.0)。我所做的是:

var webdriver = require('selenium-webdriver'),
    driver = new webdriver.Builder().forBrowser('chrome').build();
;
driver.wait(driver.executeScript("return document.readyState").then(state => {
  return state === 'complete';
}))

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);

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;

您可以删除系统。线。添加它是为了调试目的。

WebDriver driver_;

public void waitForPageLoad() {

    Wait<WebDriver> wait = new WebDriverWait(driver_, 30);
    wait.until(new Function<WebDriver, Boolean>() {
        public Boolean apply(WebDriver driver) {
            System.out.println("Current Window State       : "
                + String.valueOf(((JavascriptExecutor) driver).executeScript("return document.readyState")));
            return String
                .valueOf(((JavascriptExecutor) driver).executeScript("return document.readyState"))
                .equals("complete");
        }
    });
}

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.

您还可以使用以下代码检查页面加载

IWait<IWebDriver> wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(30.00));

 wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));
