IE 8-对象不支持此属性或方法

Question

I'm working on old IE Compatibility, specially IE 8. But, my JS is not working -> I got the Object doesn't support this property or method error on my item item_tracked

;(function () {
setTimeout(function () {
    currentItems().forEach(function (item_tracked) {
        /* item_tracked here */
        $(item_tracked.getView()).addClass('animated');
        /* item_tracked problem here */
    });
  }, 500);
})();

any idea?

Answer 1

Assuming currentItems() returns an Array, your problem is that IE8 does not support Array.prototype.forEach .

You could substite a for loop or use a polyfill .
