空手道 - 从 <a> 获取 URL使用 Javascript 的元素 [英] Karate - get URL from <a> element using Javascript

问题描述

使用空手道，我需要从标签 (href) 中提取 url.我已经在浏览器中直接使用 Javascript 进行了尝试:

Using Karate, I need to extract the url from tag (href). I have tried this using Javascript directly in browser:

document.querySelector('a[rel="noopener"]').href

它在浏览器中运行良好，我收到完整的 url 地址(https://XXXXXXXX").然后我想把它放到空手道上:

It works in browser fine, I receive whole url address ("https://XXXXXXXX"). Then I wanted to place it to Karate using:

   * def emailLink =
   """
   function(){
      var link = document.querySelector('a[rel="noopener"]').href;
      return link;
   }
   """
  * print emailLink()

但它不起作用.变量＝".我需要接收 href 值.

But it does not work. The variable = "". I need to receive the href value.

你知道如何解决这个问题吗?

Have you any Idea how to solve this?

谢谢！

推荐答案

你写的函数不工作，请阅读这里了解原因:https://github.com/intuit/karate/tree/master/karate-core#karate-vs-the-浏览器

The function you are writing will not work, and please read this to understand why: https://github.com/intuit/karate/tree/master/karate-core#karate-vs-the-browser

因此进行此更改(并注意空手道如何为您执行 document.querySelector()):

So make this change (and also note how Karate does document.querySelector() for you):

* def linkElement = locate('a[rel="noopener"]')
* def linkValue = linkElement.attribute('href')

请注意，对于第二行，这也应该有效:

Note that for the second line this should also work:

* def linkValue = linkElement.script('_.href')

甚至这个:

* def linkValue = linkElement.property('href')

开始习惯空手道中的 Element 抽象.它可能非常有用:https://github.com/intuit/空手道/树/大师/空手道核心#chaining

Start getting used to the Element abstraction in Karate. It can be very useful: https://github.com/intuit/karate/tree/master/karate-core#chaining
