this can not help me !

I do not known why,but I solved it.
at line 1097 in jquery.easyui.min.js:
if(_b3.total==0){
_b3.pageNumber=0;
_b4=0;
}
delete it ,that is OK!

The patch is available for solving this issue. It can be downloaded from http://www.jeasyui.com/download/downloads/jquery-easyui-1.4-patch.zip.

I used http://www.jeasyui.com/download/downloads/jquery-easyui-1.4-patch.zip 2014-08-27., But still request two times

Please refer to this example http://www.jeasyui.com/tutorial/datagrid/datagrid24_demo.html. It do send only one request to the remote server.

When the datagrid returns no data, there will be a request twice, if the return data is greater than 0. Then it will not repeat request

Make sure you are using the newest patch. Please try to download it from http://www.jeasyui.com/download/downloads/jquery-easyui-1.4-patch.zip.

The problem is here >> .datagrid('loadData', {"total":0,"rows":[]});
your demo >> http://www.jeasyui.com/tutorial/datagrid/datagrid24_demo.html.

and your demo is only passing the empty data that came from server, not from local..

Still double load... :(

even using your newest patch..

i think i know the problem...

your datagrid always re-reload the data if the url already assigned..
if you not  assign the url, the datagrid will reload once..i mean only reload the empty data..not the original data from remote..

need answer......ummm

your newest patch has a bug..when .datagrid('loadData', {"total":0,"rows":[]}) called..the next load function will be ignored..

Please provide an example to demonstrate your issue.

ok, using jquery-easyui-1.4-patch.js  version 20140903 .it's fixed . thanks for your help stworthy and thank you 【aswzen】。

your newest patch just solves the problem.. thanks
