对于存在的任何元素使用if条件和

try {
    Thread.sleep(1000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

隐式和显式的等待更好。

但是如果你在Java中处理一个异常，那么你可以使用这个来等待页面重新加载:

Thead.sleep(1000);

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;

Ruby实现:

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

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;
        }
    }
}

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);
