以下代码偶尔会抛出 org.openqa.selenium.WebDriverException.
The following code throws occasionally an org.openqa.selenium.WebDriverException.
WebElement element = driver.findElement(by);
element.click();
(new WebDriverWait(driver, 4, 100)).until(ExpectedConditions.stalenessOf(element));
页面如下所示(by 是 <a></a> 的选择器)
The page looks like this (by is a selector for <a></a>)
<iframe name="name">
<html id="frame">
<head>
...
</head>
<body class="frameA">
<table class="table">
<tbody>
<tr>
<td id="83">
<a></a>
</td>
</tr>
</tbody>
</table>
</body>
</html>
</iframe>
消息是 unknown error: unhandled inspector error: {"code":-32000,"message":"Cannot find context with specified id"}.element 是 iframe 的一部分,单击会导致 iframe 的内容重新加载.等待时抛出异常.这个异常是什么意思,我该如何解决?
The message is unknown error: unhandled inspector error: {"code":-32000,"message":"Cannot find context with specified id"}. element is part of an iframe and the click can cause the content of the iframe to reload. The exception is thrown while waiting. What does this exception mean and how could I fix it?
这个错误信息...
unknown error: unhandled inspector error: {"code":-32000,"message":"Cannot find context with specified id"}
...暗示 WebDriver 实例无法找到所需的元素.
...implies that the WebDriver instance was unable to locate the desired element.
正如您在问题中提到的那样,该元素是 <iframe> 的一部分,并且调用 click() 可能会导致 iframe 的内容在其中重新加载如果您需要遍历回 defaultContent 并再次使用 WebDriverWait 再次切换回所需的 iframe 然后诱导 WebDriverWait 对于 stalenessOf() 上一个元素或下一个 desired 元素 的存在,如下所示:
As you mentioned in your question that the element is part of an <iframe> and invoking click() can cause the content of the iframe to reload in that case you need to traverse back to the defaultContent and again switch back again to the desired iframe with WebDriverWait and then induce WebDriverWait either for stalenessOf() previous element or presence of next desired element as follows :
WebElement element = driver.findElement(by);
element.click();
driver.switchTo().defaultContent(); // or driver.switchTo().parentFrame();
new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("xyz")));
// wait for stalenessOf previous element (visibility of next desired element preferred)
new WebDriverWait(driver, 4, 100).until(ExpectedConditions.stalenessOf(element));
// or wait for visibility of next desired element (preferred approach)
new WebDriverWait(driver, 4, 100).until(ExpectedConditions.visibilityOfElementLocated(next_desired_element));
