getElementsByTagName排除脚本标签

Question

As the title suggests I want to exclude the script tag.

Cause while using regex (at least I think that's the right name :P)

I get to a point where something

var wdc = /something/g;

is included inside the

var foundwdc = words.match(wdc).length;

So when I alert foundwdc it gives 3 "somethings" instead of the desired two inside the body

var words = document.getElementsByTagName('body')[0].innerHTML;

Hope this is clear enough :D and hope the title is right :P

Answer 1

Use replace() to remove the script tag from string

 var words = document.getElementsByTagName('body')[0].innerHTML.replace(/<script[^>]*>[\\s\\S]*?<\\/script>/gi, ''); console.log(words); 

 hi hello <script> </script>
