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);

使用类WebDriverWait

也可以看这里

您可以期望显示一些元素。类似于c#:

WebDriver _driver = new WebDriver();
WebDriverWait _wait = new WebDriverWait(_driver, new TimeSpan(0, 1, 0));

_wait.Until(d => d.FindElement(By.Id("Id_Your_UIElement")));

下面是一个Java 8版本的目前被点赞最多的答案:

WebDriverWait wait = new WebDriverWait(myDriver, Duration.ofSeconds(15));
wait.until(webDriver -> "complete".equals(((JavascriptExecutor) webDriver)
    .executeScript("return document.readyState")));
    

其中myDriver是一个WebDriver对象(前面声明过)。

注意:注意这个方法(document.readyState)只检查DOM。

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.

我的方法很简单:

long timeOut = 5000;
    long end = System.currentTimeMillis() + timeOut;

        while (System.currentTimeMillis() < end) {

            if (String.valueOf(
                    ((JavascriptExecutor) driver)
                            .executeScript("return document.readyState"))
                    .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();
    }

}
