Get CSS class name in JavaScript

Question

I am facing a problem to get the class name from a string in JavaScript.

For example:

var ddd="<p class='Box_title'>Heading text here...</p>";

Now from that I want to get p tag's class name.

Answer 1

Browsers are good in HTML parsing:

//setup
var tmp = document.createElement('div');
tmp.innerHTML = ddd;

// get the class
var class_name = tmp.children[0].className;
