使用xpath和nightwatch.js单击动态文本 [英] clicking dynamic text using xpath and nightwatch.js

问题描述

我希望在我的应用程序中单击带有动态文本的元素.通常，要单击带有文本的元素，我会执行以下操作:

I wish to click on an element with dynamic text in my app. Generally to click on an element with text I do the following:

.useXpath().click("//*[contains(text(), 'some text')]")    

对于具有动态名称的测试，请尝试以下操作:

For my tests which have a dynamic name I try the following:

.useXpath().click("//*[contains(text(), "${name}")]")  

其中name是一个变量，其中包含新创建的帐户的名称.但是，当我尝试运行测试时，我得到以下信息:

where name is a variable which contains the name of the newly created account. However when I try to run my tests I get the following:

.useXpath().click("//*[contains(text(), "${name}")]")
                    ^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: missing ) after argument list

我错过了什么吗?我看不到缺少的地方).我也尝试过各种单/双引号等，但似乎无法正常工作.

Am I missing something? I don't see where I am missing the ). I have also tried various single/double quotes etc, but can't seem to get it working.

我也尝试使用此处概述的字符串连接:(

I have also attempted to use string concatenation as outlined here: (Passing a variable into an XPath expression in CasperJS), so my code looks like this:

 var selector = "\'//*[contains(text(), \'" + name + "\')]\'";
.useXpath().click(selector)

使用此方法运行测试时，我得到以下信息:

when I run the tests using this method I get the following:

ERROR: Unable to locate element: "'//*[contains(text(), '7ayhopt3ijhcwuo')]'" using: xpath

"7ayhopt3ijhcwuo"是要单击的正确文本，但似乎找不到它.有趣的是，如果我将这样的值硬编码:

"7ayhopt3ijhcwuo" is the correct text to click on, but it does not seem to find it. Interestingly if I hard code the value like this:

.useXpath().click("//*[contains(text(), '7ayhopt3ijhcwuo')]") 

nightwatch可以毫无问题地单击文本.

nightwatch is able to click on the text without any problems.

任何一种方法对我哪里出错的帮助都会很棒！我正在使用节点v7.8.0

Any help on where I am going wrong with either method would be great! I am using node v7.8.0

推荐答案

在字符串周围使用反引号将变量嵌入:

Either use a back-tick character around the string to embed the variable:

.useXpath().click(`//*[contains(text(), "${name}")]`)

或使用单引号和双引号的组合:

Or use a combination of single and double quotes:

.useXpath().click('//*[contains(text(), "' + name + '")]')
