Java Selenium：使用x路径单击包含逗号（，）文本的按钮

你好， 亲爱的各位， 我正在使用selenium 4.0 JDK1.8 我正在寻找一种方法来单击包含文本“蓝、黑、红”的按钮 这是该按钮的html代码

<button class="product-variation">Blue,  Black, Red</button>

rs.getString是我的结果集。 所以直接声明将是

driver.findElement(By.xpath("//button[contains(text(), \"Blue,  Black, Red"\")]")).click();

只有此按钮产生错误。 下面是堆栈跟踪：

org.openqa.selenium.NoSuchElementException: Unable to locate element: //button[contains(text(), "Blue, Black, Red")]

非常感谢您的帮助。

我测试了您的第二个xpath：

//button[contains(text(), \"Blue,  Black, Red"\")]

然而，它并没有起作用，很可能是因为最后不需要引用。我想你的意思是：

//button[contains(text(), \"Blue,  Black, Red\")]

我通常使用单引号，因为我认为可读性更好，您可以尝试使用：

//button[contains(text(), 'Blue,  Black, Red')]

如果这不起作用，可能您的元素在iframe中，您应该首先切换到它

//button[contains(text(), 'Blue,  Black, Red')]
