Question

I am trying to make a script to pick random number between two numbers . but it picks same number sometimes. i donot want to repeat same number until array is finished .

Here is my code

$(document).ready(function () {
    abc();
    test = array();

    function abc() {
        res = randomXToY(1, 10, 0);

        $('#img' + res).fadeTo(1200, 1);
        //$(this).addClass('activeImg');
        //});
        setTimeout(function () {
            removeClassImg(res)
        }, 3000);
    }

    function removeClassImg(res) {
        $('#img' + res).fadeTo(1200, 0.1);
        //$('#img' + res).removeClass('activeImg');
        abc();
    }

    function randomXToY(minVal, maxVal, floatVal) {
        var randVal = minVal + (Math.random() * (maxVal - minVal));

        return typeof floatVal == 'undefined' ? Math.round(randVal) : randVal.toFixed(floatVal);

    }
});

Does Anybody have idea about this …

You’ll have to maintain a list of numbers that have already been generated, and check against this list. Re-generate a new number if you find a dupe.
