In this example, i will show you how to generate random string or characters in javascript. We can simply generate random alphanumeric string for token or etc in jquery.

As we know jquery or javascript does not have default random string generate function so we need to create custom js function to create random and unique string in javascript. we will pass length of string and it will return random string. we will use Math.random() function too.

You need to see bellow example, you can also run bellow html file and see the results. You can also check demo.

Example:

<html>

<head>

<title>How to generate random string in javascript? - ItSolutionStuff.com</title>

</head>

<body>

<input type="button" value="Create Random String" onClick="alert(generateRandomString(10))">

</body>

<script type="text/javascript">

function generateRandomString(length) {

var text = "";

var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

for (var i = 0; i < length; i++)

text += possible.charAt(Math.floor(Math.random() * possible.length));

return text;

}

</script>

</html>

I hope it can help you...
