打开baseUrl后,我手动点击同意,然后搜索要显示的医生列表。我想翻阅一下这个列表。现在,Selenium仅通过查找">>"来点击第一次。之后它停止并发出以下错误。
driver.find_element_by_xpath("//a[contains(text(),'>>')]").click()

selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document
答案 0 :(得分:0)
错误说明了一切:
@if(!empty($products)
@foreach ($products as $product)
@if(isset($product->name) && $product->name =="")
{{$product->name}}
@else
No record
@endif
@endforeach
@else
No record Found....
@endif
在selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document
循环中的程序中,您正在页面上找到for()
标记元素,文本为&gt;&gt; 并调用<a>
和由于click()
事件, HTML DOM 发生了变化。当您的程序第二次迭代click()
循环时,标识为for()
的 WebElement 可能无法加载,但 Selenium 会尝试引用上一次迭代中已经转为陈旧的搜索。因此,您会看到 StaleElementReferenceException 。
迭代页面的令人信服的方法不是:
driver.find_element_by_xpath("//a[contains(text(),'>>')]")
对于 WebElement ,您可以将WebDriverWait与expected_conditions子句一起设置为element_to_be_clickable子句,并使用特定的页码 (例如 3 , 4 , 5 等)可点击,如下所示:
driver.find_element_by_xpath("//a[contains(text(),'>>')]").click()
