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;
            }
        }

一般来说，使用Selenium 2.0时，web驱动程序应该只在确定页面已加载后才将控制权返回给调用代码。如果没有，您可以调用waitforeleement，它循环调用findelement，直到找到它或超时(可以设置超时)。

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);

更多条件可以在这里找到: http://selenide.org/javadoc/3.0/com/codeborne/selenide/Condition.html

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"));

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);

您可以尝试这段代码，让页面完全加载，直到找到元素为止。

public void waitForBrowserToLoadCompletely() {
    String state = null;
    String oldstate = null;
    try {
        System.out.print("Waiting for browser loading to complete");

        int i = 0;
        while (i < 5) {
            Thread.sleep(1000);
            state = ((JavascriptExecutor) driver).executeScript("return document.readyState;").toString();
            System.out.print("." + Character.toUpperCase(state.charAt(0)) + ".");
            if (state.equals("interactive") || state.equals("loading"))
                break;
            /*
             * If browser in 'complete' state since last X seconds. Return.
             */

            if (i == 1 && state.equals("complete")) {
                System.out.println();
                return;
            }
            i++;
        }
        i = 0;
        oldstate = null;
        Thread.sleep(2000);

        /*
         * Now wait for state to become complete
         */
        while (true) {
            state = ((JavascriptExecutor) driver).executeScript("return document.readyState;").toString();
            System.out.print("." + state.charAt(0) + ".");
            if (state.equals("complete"))
                break;

            if (state.equals(oldstate))
                i++;
            else
                i = 0;
            /*
             * If browser state is same (loading/interactive) since last 60
             * secs. Refresh the page.
             */
            if (i == 15 && state.equals("loading")) {
                System.out.println("\nBrowser in " + state + " state since last 60 secs. So refreshing browser.");
                driver.navigate().refresh();
                System.out.print("Waiting for browser loading to complete");
                i = 0;
            } else if (i == 6 && state.equals("interactive")) {
                System.out.println(
                        "\nBrowser in " + state + " state since last 30 secs. So starting with execution.");
                return;
            }

            Thread.sleep(4000);
            oldstate = state;

        }
        System.out.println();

    } catch (InterruptedException ie) {
        ie.printStackTrace();
    }
}
