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

Question

附上源码: $(document).ready(function () {

        });
        function reload() {

                $('#Gride1').treegrid('reload', node.HUJIBH);
            } else {
                $('#Gride1').treegrid('reload');
            }
        }

        }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

Answer 1

url: 'xingZhengDmzd.aspx?action=paint&trans=0&timeid=' + Math.random();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
