kendo ui 实现MVVM

MVVM                    model----view model----model 实现页面和model之间的动态绑定

 

grid 支持 events  source  visible绑定

 

第一步建立一个observable对象   对象为参数

       var viewModel = kendo.observable()

第二步实现视图与 viewModel绑定

 kendo.bind($("#example"), viewModel);  //jQuery对象

注意对某一属性设置值时使用

  this.set("isDescriptionShown", true);  
     showDescription: function(e) {
     　　e.stopPropagation(); 
 　　　　e.preventDefault();
        this.set("isDescriptionShown", true);  //给属性赋值
   }
