Imran对Java 7的回答是:

    WebDriverWait wait = new WebDriverWait(driver, 30);

    wait.until(new ExpectedCondition<Boolean>() {
        public Boolean apply(WebDriver wdriver) {
            return ((JavascriptExecutor) driver).executeScript(
                "return document.readyState"
            ).equals("complete");
        }
    });

driver.asserts().assertElementFound("Page was not loaded",
By.xpath("//div[@id='actionsContainer']"),Constants.LOOKUP_TIMEOUT);

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.

在脚本中调用下面的函数，这将等待页面未使用javascript加载

public static boolean isloadComplete(WebDriver driver)
{
    return ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("loaded")
            || ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("complete");
}

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");
        }
    });
}

Ruby实现:

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