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 }
