EasyUI calculates the values of the two columns in the Editable datagrid.

@ Author YHC

In this tutorial, you will learn how to include an operation column in an editable datagrid. An operation column usually contains some operation values from one or more other columns.

First, create an editable datagrid, which is some of the Editable columns we have created. The 'listprice', 'amount', and 'unitcost' columns are defined as the numberbox editing type, the operation column is the 'unitcost' field,

Returns the result of multiplying listprice by the amount column.

[Html]
<Table id = "tt" style = "width: 600px; height: auto"
Title = "Editable DataGrid with Calculated Column" iconCls = "icon-edit" singleSelect = "true"
IdField = "itemid" url = "data/datagrid_data.json">
<Thead>
<Tr>
<Th field = "itemid" width = "80"> Item ID </th>
<Th field = "listprice" width = "80" align = "right" editor = "{type: 'numberbox', options: {precision: 1 }}"> List Price </th>
<Th field = "amount" width = "80" align = "right" editor = "{type: 'numberbox', options: {precision: 0 }}"> Amount </th>
<Th field = "unitcost" width = "80" align = "right" editor = "numberbox"> Unit Cost </th>
<Th field = "attr1" width = "150" editor = "text"> Attribute </th>
<Th field = "status" width = "60" align = "center" editor = "{type: 'checkbox', options: {on: 'P', off: ''}}"> Status </th>
</Tr>
</Thead>
</Table>

<Table id = "tt" style = "width: 600px; height: auto"
Title = "Editable DataGrid with Calculated Column" iconCls = "icon-edit" singleSelect = "true"
IdField = "itemid" url = "data/datagrid_data.json">
<Thead>
<Tr>
<Th field = "itemid" width = "80"> Item ID </th>
<Th field = "listprice" width = "80" align = "right" editor = "{type: 'numberbox', options: {precision: 1 }}"> List Price </th>
<Th field = "amount" width = "80" align = "right" editor = "{type: 'numberbox', options: {precision: 0 }}"> Amount </th>
<Th field = "unitcost" width = "80" align = "right" editor = "numberbox"> Unit Cost </th>
<Th field = "attr1" width = "150" editor = "text"> Attribute </th>
<Th field = "status" width = "60" align = "center" editor = "{type: 'checkbox', options: {on: 'P', off: ''}}"> Status </th>
</Tr>
</Thead>
</Table> when a user clicks a row, an edit action is started.

[Javascript]
Var lastIndex;
$ ('# Tt'). datagrid ({
OnClickRow: function (rowIndex ){
If (lastIndex! = RowIndex ){
$ ('# Tt'). datagrid ('enabled', lastIndex );
$ ('# Tt'). datagrid ('ineinedit', rowIndex );
SetEditing (rowIndex );
}
LastIndex = rowIndex;
}
});

Var lastIndex;
$ ('# Tt'). datagrid ({
OnClickRow: function (rowIndex ){
If (lastIndex! = RowIndex ){
$ ('# Tt'). datagrid ('enabled', lastIndex );
$ ('# Tt'). datagrid ('ineinedit', rowIndex );
SetEditing (rowIndex );
}
LastIndex = rowIndex;
}
}); Create an operational relationship between some columns. We should get editors and bind some events to them.

[Javascript]
Function setEditing (rowIndex ){
Var editors = $ ('# tt'). datagrid ('geteditor', rowIndex );
Var priceEditor = editors [0];
Var amountEditor = editors [1];
Var costEditor = editors [2];
PriceEditor.tar get. bind ('change', function (){
Calculate ();
});
AmountEditor.tar get. bind ('change', function (){
Calculate ();
});
Function calculate (){
Var cost = priceEditor.tar get. val () * amountEditor.tar get. val ();
Values (costeditor.tar get). numberbox ('setvalue', cost );
}
}
