问题描述
我正在尝试使用以下方法搜索文档
I'm trying to search the document using:
document.querySelectorAll("a[href*=google.com]")[0].href;
要在文档中搜索包含google.com网址的href奇怪的是，到目前为止，它一直对我有用会发生什么事?这是向我显示的错误:
To search the document for a href containing the google.com URL The strange thing is that it has always worked for me to this day What will have happened? This is the error that shows me:
Uncaught DOMException: Failed to execute 'querySelectorAll' on 'Document': 'a[href=google.com]' is not a valid selector.
at <anonymous>:1:10
我再说一遍，我已经使用该代码很多年了，今天它已经停止工作，请问任何解决方案吗?
I repeat, I have been using that code for years and today it has stopped working, any solution please?

<head>

<body>
<a rel="nofollow" href="//www.google.com/" target="_blank">GOOGLE</a>

console.log(result)<html>
<head>
<title> MY WEB </title>
