(转)jquery easyui treegrid使用小结 （主要讲的是如何编辑easyui中的行信息包括添加 下拉列表等）

在实际应用中可能会碰到不同的需求，比如会根据每行不同的参数或属性设置来设置同列不同的editor类型，这时原有的例子就显的有点太过简单，不能实现我们的需求，现在应用我在项目中的操作为例，显示下实现同列不同操作的情况：（在这，我把例子的情况完全整合到了js里面配置实现，如有习惯于js实现方式的也可参考）  

html:  

<table id="comTypeAndPropertyTree"></table>//个人觉得这样更显的页面清晰，所有的配置都放到js里实现  

js:  

var types = [
      {typeId:0,typeName:'Normal'},
      {typeId:1,typeName:'URL'},
      {typeId:2,typeName:'Symbol'}
  ];  

$(function(){
     var lastIndex;
   $('#comTypeAndPropertyTree').treegrid({
    title:'产品库配置',
    height:550,
    rownumbers: true,
    animate:true,
    url:'getComTypeAndPropertyTreeRoot.action',
    idField:'id',//id=productId_propId_largetypeId_midlletypeId_comtypeId;
    treeField:'name',
    frozenColumns:[[
                 {title:'名称',field:'name',width:300,
                  formatter:function(value){
                   return '<span style="color:red">'+value+'</span>';
                  }
                 }
    ]],
    columns:[[
        {title:'library',field:'library',width:100,editor:{type:'checkbox',options:{on:'1',off:'0'}},
         formatter:function(value,row){
         if(!row.leaf){
          if(value==1){
            return '<img src="data:images/checkbox_checked.jpg"/>';
           }else{

实现效果图：实现流程：onDblClickRow --（ onBeforeEdit -- onAfterEdit） -- onClickRow，操作上只需要双击和单击两个事件来完成操作，而另两个事件是在中间自动实现完成。
