EasyUI IE下的奇怪现象 TreeGrid reload事件不能刷新数据(节点)

[cyw1592951]

附上源码:

 $(document).ready(function () {
            BinDingtreeGride();             
        });
        function reload() {
            var node = $('#Gride1').treegrid('getSelected');
            if (node) {
                $('#Gride1').treegrid('reload', node.HUJIBH);
            } else {
                $('#Gride1').treegrid('reload');
            }
        }      
        function BinDingtreeGride() {

谷歌浏览器下，一切正常，动态的加载每一级，删除之树内的节点，可及时刷新其父节点下的所有内容，而在IE下边儿就是不行，不知道为什么反复的在EasyUI下查找API，反复的试验 reload refresh 未果，求解

关于ajax浏览器缓存的清除

1:在AJAX请求的页面后加个随机函数,我们可以使用随机时间函数

2:在XMLHttpRequest发送请求之前加上XMLHttpRequest.setRequestHeader("If-Modified-Since","0")一般情况下,这里的XMLHttpRequest不会直接使用你应该可以找到这样的代码

可以有效的解决下些不保存数据的更新程度问题
