有人可以告诉我为什么上面的代码不起作用？我在eclipse中运行上面的引用并得到以下错误

Eclipse版本：3.7.1 Firefox版本：30

Answer 1

首先，您的xpath不正确，一旦您在文本框中输入内容，就会再次显示您尝试单击的按钮。

这将有效，

driver.findElement(By.xpath("//*[@id='gbqfq']")).sendKeys("Test"); 
driver.findElement(By.xpath("//*[@id='gbqfb']/span")).click();

您使用的是其他按钮的错误路径。为什么呢？

bcoz，当你在google中输入内容时，你试图点击的按钮（Google按钮）将会消失，完全会出现一个新页面（你可以注意到文本框移动到右上角，然后是蓝色搜索图标将出现）。

因此请注意应用程序中发生的情况，然后尝试自动化它。

Answer 2

您的xpath无效。请尝试：

“// * [@ id中= 'gbqfba']”

大多数浏览器都允许您测试Xpath。

或者，css选择器将是;

“＃gbqfba”

或者Selenium也允许你通过id找到;

“gbqfba”

我个人更喜欢CSS选择器。您选择XPath的原因是什么？
