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");
}

SeleniumWaiter:

import com.google.common.base.Function;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.WebDriverWait;

public class SeleniumWaiter {

      private WebDriver driver;

      public SeleniumWaiter(WebDriver driver) {
           this.driver = driver;
      }

      public WebElement waitForMe(By locatorname, int timeout){
           WebDriverWait wait = new WebDriverWait(driver, timeout);
           return wait.until(SeleniumWaiter.presenceOfElementLocated(locatorname));
      }

      public static Function<WebDriver, WebElement> presenceOfElementLocated(final By locator) {
            // TODO Auto-generated method stub
            return new Function<WebDriver, WebElement>() {
                 @Override
                 public WebElement apply(WebDriver driver) {
                      return driver.findElement(locator);
                 }
            };
      }
 }

对你来说:

_waiter = new SeleniumWaiter(_driver);

try {
   _waiter.waitForMe(By.xpath("//..."), 10);
} 
catch (Exception e) {
   // Error
}

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();
}

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)。

我使用node + selenium-webdriver(现在的版本是3.5.0)。我所做的是:

var webdriver = require('selenium-webdriver'),
    driver = new webdriver.Builder().forBrowser('chrome').build();
;
driver.wait(driver.executeScript("return document.readyState").then(state => {
  return state === 'complete';
}))

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"));
