jQuery easyui datagird编辑行删除行功能的实现代码

神马是easyui

jQuery EasyUI是一组基于jQuery的UI插件集合，而jQuery EasyUI的目标就是帮助web开发者更轻松的打造出功能丰富并且美观的UI界面。开发者不需要编写复杂的javascript，也不需要对css样式有深入的了解，开发者需要了解的只有一些简单的html标签。

jQuery EasyUI为我们提供了大多数UI控件的使用，如：accordion，combobox，menu，dialog，tabs，tree，validatebox，window等等。

下面通过代码看下easyui datagird编辑行删除行功能，具体代码如下所示：

function init(){
   var editRow = undefined;
   var oldMoney = undefined;
   $("#dg").datagrid({
     url:"../foreignexchange/fexLedgerManager.do?method=queryApplyData&parentId="+parentId,
     fitColumns:false,//自适应宽度，占满,不能和冻结列同时设置成true
     striped:true,  //斑马线效果
    singleSelect:false,     //是否单选
    pagination:false,
     height:140,
     columns:[[
