😳 Ever felt a little embarassed sharing your JavaScript? Let's fix it.

In this example you can get all occurrences of an email address on the web page. Useful if you have to change the email address for a specific page or sub section of your site. Might be useful to screen scrape email addresses off web pages too, although that’s not what i am trying to achieve here. See more jQuery .each Examples.

i = insensitive (case)
g= global search
m = match over multiple lines

var iframeSrc = 'test.html?param=value&email=noobs@noob.com&moreparams=values';
var emailRegex= /[._a-zA-Z0-9-]+@[._a-zA-Z0-9-]+/igm;

console.log(iframeSrc);
console.log(emailRegex.test(iframeSrc));
console.log(iframeSrc.match(emailRegex));

$.each(iframeSrc.match(emailRegex), function(index, value) { 
     console.log(index + ". " + value);
});
//output: 0. noobs@noob.com

This find all html between the tags:

var secureQueryRegex = /()/igm;
/* loop for each query found in data */
$.each(data.match(secureQueryRegex), function(index, value) {
	console.log(index + ". " + value);
});
//example output: 
//0. query=find all shops
//1. query=find all locations
//etc...
