Flex DataGrid column 排序

实现表格中某列按 数值排序（非字符串），代码如下：

import mx.utils.ObjectUtil;

//按数值 排序 功能

protected function compareIdNumeric(obj1:Object, obj2:Object, column:GridColumn):int {var n1:Number = new Number(obj1[column.dataField]);var n2:Number = new Number(obj2[column.dataField]);return ObjectUtil.numericCompare(n1,n2);}

<!--某个column设置 调用排序方法-->

<s:GridColumn headerText="成功率" dataField="success" sortCompareFunction="compareIdNumeric">
