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);

/**
 * 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。

private static void checkPageIsReady(WebDriver driver) {
    JavascriptExecutor js = (JavascriptExecutor) driver;

    // Initially bellow given if condition will check ready state of page.
    if (js.executeScript("return document.readyState").toString().equals("complete")) {
        System.out.println("Page Is loaded.");
        return;
    }

    // This loop will rotate for 25 times to check If page Is ready after
    // every 1 second.
    // You can replace your value with 25 If you wants to Increase or
    // decrease wait time.
    for (int i = 0; i < 25; i++) {
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
        }
        // To check page ready state.
        if (js.executeScript("return document.readyState").toString().equals("complete")) {
            break;
        }
    }
}

public static int counter = 0;

public void stepGeneralWait() {

    boolean breakIt = true;

    while (true) {
        breakIt = true;
        try {

            do{
                // here put e.g. your spinner ID
                Controller.driver.findElement(By.xpath("//*[@id='static']/div[8]/img")).click();
                Thread.sleep(10000);

                counter++;

                if (counter > 3){
                    breakIt = false;

                }
            }
            while (breakIt);



        } catch (Exception e) {
            if (e.getMessage().contains("element is not attached")) {
                breakIt = false;
            }
        }
        if (breakIt) {
            break;
        }

    }

    try {
        Thread.sleep(12000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

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;

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);
