js settimeout

关键：settimeout要放到遍历的外边（ele为数组），才能使得循环遍历生效。

  function getElementsByClassName(n) {
        var classElements = [], allElements = document.getElementsByTagName(‘*‘);
        for (var i = 0; i < allElements.length; i++) {

            if (allElements[i].className == n) {

                classElements[classElements.length] = allElements[i];

            }
        }
        return classElements;
    }
    function loaded() {
        var ele = getElementsByClassName(‘myScrollbarH‘);
        setTimeout(function () {

            for (i = 0; i < ele.length; i++) {
                var element = ele[i].id;
                //alert(element);
                new iScroll(element, {
                    scrollbarClass: ‘myScrollbar‘
                });
            }

        }, 100);
    }
