JavaScript Random Number; quick random number; Math.random(); substring();

Content

I wanted to avoid specifying a max and min. // Math.random(): produces integer -> 0.473239055961688 // toString(): from integer to string -> '0.473239055961688' // substring(2): extract after period -> '473239055961688' var str=Math.random().toString().substring(2); alert(str); This example function requires a max and min. // https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Global_Objects/Math/random#Examples function getRandomInt(min, max){     return Math.floor(Math.random() * (max - min + 1)) + min; }
