查找字符串长度而不计算包含的html标签

Question

I have a paragraph which has HTML tags in it. I need to restrict it to 100 characters after the parse of HTML. For example

Hello<a href ="#"> World </a>

If my length check is for 8, then my HTML should be Hello Wo where Wo should be an anchor tag. There can be any other tags. Any help would be appreciated.

Answer 1

 $(document).ready(function(){ var $html=$('<span></span>'); $html.append('Hello<a href ="#"> World </a>'); var text=$html.text(); console.log("Text :: "+text); console.log("Length :: "+text.length); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 

Using this way you can create html elment virtually then text() will parse the text content from html.

Answer 2

You can use a REGEX expresion when getting the innerHTML

Then count the characters.

Example:

 var regex = /(<([^>]+)>)/ig; var body = 'Hello<a href ="#"> World </a>'; var result = body.replace(regex, ""); console.log(result + ' ' + result.length);
