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.

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;

var RegExp = /class='(.+)'/;
var result = RegExp.exec("<p class='Box_title'>Heading text here...</p>");
this will return an array with class name as one of it's elements

seriously, why would you use regex for this when you've got an HTML parser right there ready to use?
var d = "<p class='Box_title'>Heading text here...</p>";
var cls = d.match(/class\=\'(.*)\'/);
alert(cls[1]);
This regex will return your class name

the you are writing it wrong, I have tested it and its working, if you are using firebug, just paste my code into console and run it
