解决easyUI 1.2.6 + datagrid在 IE浏览器下无法重新加载、查询
I) easyUI 1.2.6 datagrid在 IE浏览器目前存在的问题 1:无法重新加载、查询 var row = $('#dg_user_table').datagrid('getSelected'); $('#dg_userPri_table').datagrid( { method : 'POST', height : 280, url : remotePathq 'user/role/' row.id, 。。。
I) easyUI 1.2.6 + datagrid在 IE浏览器目前存在的问题
1:无法重新加载、查询
var row = $('#dg_user_table').datagrid('getSelected');
$('#dg_userPri_table').datagrid(
{
method : 'POST',
height : 280,
url : remotePathq + 'user/role/' + row.id,
。。。。。。
});
BUG:在没有清空IE缓存或者关闭IE重新打开,会出现查询数据为上次的缓存、历史数据,非即时数据:(其它firefox,谷歌浏览器正常)
原因:datagrid发送的'POST'请求地址一样,导致IE浏览器不会重新查询数据,而是从上次的缓存里直接获取历史数据;
2 :reload方法使用无效:
即$('#dg_user_table').datagrid('reload');不触发datagrid URL请求,数据没有更新;
原因:datagrid发送的'POST'请求地址一样,导致IE浏览器不会重新查询数据,而是从上次的缓存里直接获取历史数据;(同上)
II)解决办法:
对HTTP RESTFUL服务地址加上唯一值随机数,区别每次加载的RESTFUL服务地址;
即:
var randomNu = (new Date().getTime()) ^ Math.random();
url : remotePathq + 'user/role/' + row.id+"?_="+randomNu,
修正后为:
var row = $('#dg_user_table').datagrid('getSelected');
var randomNu = (new Date().getTime()) ^ Math.random();
$('#dg_userPri_table').datagrid(
{
method : 'POST',
height : 280,
url : remotePathq + 'user/role/' + row.id+"?_="+randomNu,
。。。。。。
});
便可解决1 2 问题,使reload方法也可用;
