str_shuffle（）在javascript中等效？

Question

Like the str_shuffle() function in PHP, is there a function similar in shuffling the string in javascript ?

Please help !

Answer 1

No such function exist, you'll write one yourself. Here's an example:

function shuffle(string) {
    var parts = string.split('');
    for (var i = parts.length; i > 0;) {
        var random = parseInt(Math.random() * i);
        var temp = parts[--i];
        parts[i] = parts[random];
        parts[random] = temp;
    }
    return parts.join('');
}

alert(shuffle('abcdef'));
