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>';  
                  }  
                 }  
    ]],

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。
