虽然在WebPage中可见，但无法找到元素

标签： java html selenium-webdriver

我正在使用Java进行Selenium Webdriver自动化。

请查看网页http://1drv.ms/1CMtRxd的附加HTML摘录，并找到相同http://1drv.ms/1JzXarv的用户界面。

从html中，了解所有UI元素都是在表中构建的，并且此处确定的问题是，无法找到右侧表中存在的元素。

但是，在自动化脚本中查找和使用左侧表中的元素没有问题。

你能告诉我们这两张桌子之间有什么区别，以及为什么我在播放时无法找到右手边桌子的元素。

另外，请有人帮我解决这个问题。

请找到代码提取：

（使用网页对象模型编码）

在POM课程中： 

@Test(description = "Test to Track the Order")
    public void searchOrder() throws Exception
    {
        SearchRequest searchReq = PageFactory.initElements(wd, SearchRequest.class);


        wd.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        searchReq.enterTrackingID("161471");
        searchReq.clickSearchButton();

    }

在页面工厂类中： 

public class SearchRequest
{

    @FindBy(how = How.ID, using = "cpportal:searchByID")
    public WebElement   trackingID;

    public void enterTrackingID(String trackingID)
    {
        this.trackingID.clear();
        this.trackingID.sendKeys(trackingID);
    }

    @FindBy(how = How.NAME, using = " cpportal:j_idt56 ")
    public WebElement   search;

    public void clickSearchButton()
    {
        this.search.click();
    }
}

异常抛出：

1 个答案:

答案 0 :(得分：1)

这可能是一个ajax元素。一段时间后元素可见。

- ：

的返回值是多少 
trackingID.isDisplayed();

Implicit wait

可以避免这种情况 
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

或通过WebDriver等待

new WebDriverWait(driver, 10).until(ExpectedConditions.presenceOfElementLocated(trackingID));

希望有所帮助
