如何让Selenium 2.0等待页面加载?


当前回答

使用下面的代码,它是非常容易和简单的页面加载。

public void PageLoad(IWebDriver driver, By by)
{
    try
    {
        Console.WriteLine("PageLoad" + by);
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));
        wait.Until(ExpectedConditions.ElementIsVisible(by));
        wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30)); // 30 seconds wait until element not found. 
        wait.Until(ExpectedConditions.ElementToBeClickable(by));


    }
    catch (Exception ex)
    {

        Console.WriteLine(ex.Message);
        Assert.Fail("Element not found!")
    }
}

我希望这对你有所帮助。

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");
}

使用这个函数

public void waitForPageLoad(ChromeDriver d){
        String s="";
        while(!s.equals("complete")){
        s=(String) d.executeScript("return document.readyState");
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        }

    }

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
}

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");
        }
    });
}

WebDriver driver = new ff / chrome / anyDriverYouWish(); .timeouts driver.manage()()。TimeUnit.SECONDS implicitlyWait(10日); 最多等待10秒。 WebDriverWait wait = new WebDriverWait(driver, 10); wait.until (ExpectedConditions。visibilityOf (WebElement元素)); FluentWait <司机> FluentWait; fluentWait = new fluentWait <>(driver)。TimeUnit.SECONDS withTimeout(30日) TimeUnit.MILLISECONDS .pollingEvery (200) . ignore (NoSuchElementException.class);

最后一个选项的优点是可以包含预期的异常,以便继续执行。
