Easyui datagrid 1.4 requests twice, easyuidatagrid

When the returned data is {rows: [], total: 0}, the datagrid requests twice.

Problems with the framework itself are hard to find out the cause, and google eventually finds a solution in the easyui community.

The attachment is the bug fixing code of version 1.4. You only need to add this js Code after the js is imported to the page (note that it should be placed behind easyui. min. js)

How to remove multiple rows in easyui datagrid

Function del (){
Var rows = $ ('# tt'). datagrid ("getSelections ");
Var copyRows = [];
For (var j = 0; j <rows. length; j ++ ){
CopyRows. push (rows [j]);
}
For (var I = 0; I <copyRows. length; I ++ ){
Var index = $ ('# tt'). datagrid ('getrowindex', copyRows [I]);
$ ('# Tt'). datagrid ('delterow', index );
}
}

Cause: In versions earlier than the easyui-1.3.3, The datatgrid Method for deleting row deleteRow will call opts after row deletion. view. deleteRow. call (opts. view, _ 4d2, _ 4d3); refresh the index of the row on the page, and the index will change; your original rows data will also change, copy the rows to another array;
 
Why can't jquery easyui datagrid reload be refreshed in time?

I also encountered a similar problem.
$ ('# Maintable'). datagrid ({url: "datagrid_data.php", queryParams: {pageNumber: pageNumber1, pageSize: pageSize1}, method: "post "});
