javascript - Selenium 驱动程序在 click() 后不反射(reflect)页面变化

Question

以下代码返回的源不反射(reflect)调用 click() 后由 javascript 引起的网页变化。我错过了什么？

driver.findElement(By.xpath(xpath)).click(); // changes page content
Thread.sleep(10000);
String src = driver.getPageSource(); // src does not reflect changes

Answer 1

您不应依赖网络驱动程序的 getPageSource() 方法。

getPageSource

java.lang.String getPageSource()

Get the source of the last loaded page. If the page has been modified after loading (for example, by Javascript) there is no guarantee that the returned text is that of the modified page. Please consult the documentation of the particular driver being used to determine whether the returned text reflects the current state of the page or the text last sent by the web server. The page source returned is a representation of the underlying DOM: do not expect it to be formatted or escaped in the same way as the response sent from the web server. Think of it as an artist's impression.

Returns: The source of the current page
