javascript regexp：查找包含标记内的字符串或标记内的锚

Question

I have the following which checks for string str inside the text portion of an anchor, ie <a href="#">text containing str</a> :

RegExp('<a.*?>.*?str.*?</a>', 'gi')

However, I need it to check inside the tag as well, ie for <a href="link_containing_str">some text</a> as well.

I tried the following but it does not work:

RegExp('<a.*?str.*?</a>', 'gi')

What syntax do I need to use for this?

Answer 1

Instead of using Regex, just check for the existence of the string in the innerHTML or href properties on the object:

 document.querySelectorAll('a').forEach(x => { console.log(x.innerHTML.includes('str') || x.href.indexOf('str') != -1); }) 

 <a href="#">text containing str</a> <a href="link_containing_str">some text</a> <a href="#">text</a> <a href="link">some text</a>
