        var targetStr = '1,2,3,4,5,6,7';
        var array = targetStr.split(',');
        //use JQuery
        $.each(array, function (index, item) {
            alert('index:' + index + ', item:' + item);

        //use forEach in Javascript
        array.forEach(function (item, index) {
            alert('index:' + index + ', item:' + item);

        //generic way in Javascript
        for (i = 0; i < array.length; i++) {
            alert('index:' + i + ', item:' + array[i]);

forEach method is not supported by all browsers. I recommend using Jquery or generic way in Javascript.
