jQuery EasyUI DataGrid - Column Calculation
In this tutorial, you will learn how to include a calculated column in an editable DataGrid. A calculated column typically contains values derived from one or more other columns.
First, create an editable DataGrid. Here we define some editable columns: 'listprice', 'amount', and 'unitcost' columns are defined with the numberbox editor type. The calculated column is the 'unitcost' field, which will be the result of multiplying the listprice by the amount column.
| Item ID |
List Price |
Amount |
Unit Cost |
Attribute |
Status |
When a user clicks a row, we initiate an editing action.
var lastIndex;
$('#tt').datagrid({
onClickRow:function(rowIndex){
if (lastIndex != rowIndex){
$('#tt').datagrid('endEdit', lastIndex);
$('#tt').datagrid('beginEdit', rowIndex);
setEditing(rowIndex);
}
lastIndex = rowIndex;
}
});
To create a calculation relationship between columns, we need to get the current editors and bind some events to them.
function setEditing(rowIndex){
var editors = $('#tt').datagrid('getEditors', rowIndex);
var priceEditor = editors;
var amountEditor = editors;
var costEditor = editors;
priceEditor.target.bind('change', function(){
calculate();
});
amountEditor.target.bind('change', function(){
calculate();
});
function calculate(){
var cost = priceEditor.target.val() * amountEditor.target.val();
$(costEditor.target).numberbox('setValue',cost);
}
}
