jEasyUI formatting columns

The following example formats column data in easyui DataGrid and uses the formatter of a custom column. If the price is less than 20, the text turns red.

In order to format a DataGrid column, we need to set the formatter property, which is a function. This formatting function contains three parameters:

• #value: the field value corresponding to the current column.

• row: The current row record data.

• index: The current row index.

Create DataGrid

	<table id="tt" title="Formatting Columns" class="easyui-datagrid" style="width:550px;height:250px"
			url="data/datagrid_data.json"
			singleSelect="true" iconCls="icon-save">
		<thead>
			<tr>
				<th field="itemid" width="80">Item ID</th>
				<th field="productid" width="80">Product ID</th>
				<th field="listprice" width="80" align="right" formatter="formatPrice">List Price</th>
				<th field="unitcost" width="80" align="right">Unit Cost</th>
				<th field="attr1" width="100">Attribute</th>
				<th field="status" width="60" align="center">Stauts</th>
			</tr>
		</thead>
	</table>

Please note that the 'listprice' field has a 'formatter' attribute, which is used to specify the formatting function.

Write formatting function

	function formatPrice(val,row){
		if (val < 20){
			return '<span style="color:red;">('+val+')</span>';
		} else {
			return val;
		}
	}
