How to generate random text using JavaScript

In this post I’m going to share a JavaScript function, if you call it (and assign some number as length of randomized text you want), it will return random text.

Here is the function:

function genRand(length) {
	var tmp = "";
	var availChars = "abcd12345";
	for (var i = 0; i < length; i++)
	tmp += availChars.charAt(Math.floor(Math.random() * availChars.length));
	return tmp;
}

And also watch this video to see the demonstration:
