DataGrid result set clearing method in EasyUI component under Jquery_jquery

Now we have completed the corresponding function, and after selecting "Region" and "Agency Company" and ensuring that these two options have values at the same time, the first page will be automatically refreshed A DataGrid (DG1) result set

But after DG1 is refreshed, the two following DG2 and DG3 still retain the previous results

I tried to change the query conditions of DG2 and DG3 , manually passing an empty ID value to the query() method, but it was later treated as the first query return by the background Controller layer

So I found such a method that can give them an empty result set string

As follows

Copy the code The code is as follows:

 
//Modify the maintenance company selection Resubmit the query after the box 
function query1(){ 
var params = $('#dg1').datagrid('options').queryParams; 
params.region = $('#region') .combotree('getValue'); 
params.company_id = $('#company_id').combotree('getValue'); 
params.contract_type = "line";//*Currently written as line, Later, it will be optimized into a tab page 
if(params.company_id == "" || params.region == ""){ 
return; 
} 
$("#dg1").datagrid ('load'); 
$('#dg2').datagrid('loadData', { total: 0, rows: [] });//Clear the DateGrid below 
$('#dg3') .datagrid('loadData', { total: 0, rows: [] });//Clear the DateGrid below 
} 

In this way, the data in the result set in DG2 and DG3 can be cleared smoothly

Another method is to traverse and delete the data in the result set

Copy the code The code is as follows:

 
var item = $('#filegrid').datagrid('getRows'); 
if (item) { 
for (var i = item.length - 1; i > = 0; i--) { 
var index = $('#filegrid').datagrid('getRowIndex', item[i]); 
$('#filegrid').datagrid('deleteRow' , index); 
} 
}
