Selenium Firefox驱动程序中的WebElement的GetAttribute返回空 [英] GetAttribute of WebElement in Selenium Firefox Driver Returns Empty

问题描述

所以我有一个写的测试，测试运行并使用 Selenium ChromeDriver 就好了。我的任务是在 FirefoxDriver 上进行测试。

部分测试我们将文本输入到登录字段中，然后检查登录字段以确保输入。我们检查字段的方式是这样的

  public virtual string Text => WebElement.GetAttribute（ 值）; $！
 while（！Text.Equals >这在 Chrome 中工作得很好。但是它并不在 Firefox 中。当我调试测试时，它显示 Text 是或空/空白。如果我打开Firefox，我可以执行 document.getElementById（login）.value ，并返回正确的值。  FirefoxDriver 中的 WebElement.GetAttribute 的不同实现方式 
>或者我只是错过了什么？
解决方案 
很难说你的情况为什么不工作 Firefox ，浏览器之间没有不同的实现。您可以使用 IJavascriptExecutor 替代解决方案，如下所示： -  
 $ b $ pre $ I $ aaScriptScriptExecutor js = driver作为IJavaScriptExecutor; 
 string Text =（string）js.ExecuteScript（return arguments [0] .value，WebElement）; 
  

So I have a test that was written, and the test runs and works using the Selenium ChromeDriver just fine. I was tasked with getting the tests working on the FirefoxDriver as well.

Part of the test we input text into a login field, and then check the login field to make sure it was input. The way we check the field is like this

public virtual string Text => WebElement.GetAttribute("value");
while (!Text.Equals(inputText) && count++ < 3)

This works perfectly fine in Chrome. However it does not in Firefox. When I debug the test, it shows that Text is "" or empty/blank. If I open Firefox, I can do this document.getElementById("login").value and it returns the correct value.

Is WebElement.GetAttribute implemented differently in the FirefoxDriver or am I just missing something?

解决方案

It's hard to say in your case why is not working on Firefox, there is no different implementation between browsers. You can try alternate solution using IJavascriptExecutor instead as below :-

IJavaScriptExecutor js = driver as IJavaScriptExecutor;
string Text = (string)js.ExecuteScript("return arguments[0].value", WebElement);
