js实现一个简单的MVVM框架示例

<form class="form-horizontal" role="form" data-context="TestController">
  <div class="form-group">
   <legend>Form title</legend>
  </div>
  <div class="form-group">
   <div class="col-sm-6 col-sm-offset-2">
    <input type="text" class="form-control" bind-val="age,format=format" style="margin:5px 0" />
    <input type="text" class="form-control" bind-val="desc" style="margin:5px 0" />
    <input type="range" min="10" max="300" bind-val="age" step="10" class="form-control" style="margin:5px 0" />
    <input type="button" class="btn btn-primary" value="更新" style="margin:5px 0" on-click="update" />
   </div>
  </div>
 </form>
 <script>
  var TestController = {
   data: {
    name: 'xiaoming',
    age: 3,
    desc: function() {
　　　　　　　　　　　　return this.name + ' likes looking little movie. he should take care of his body' 
    }
   },
   format: function(val) {
    return val + '岁'
   },
   update: function() {
    this.name = 'this is a test'
    this.age = 18
   }
  }
  $('body').controller()
 </script>

$.controller.addDirective("val", {
  init: function (observer) {
   if (observer.$ele.is('input,select')) {
    //监听onchange事件
    observer.$ele.on('input propertychange', function () {
     var newVal = $(this).val()
     observer.writeValue(newVal)
    })
   }
  },
  update: function ($ele, newVal, controller) {
   $ele.val && $ele.val(newVal)
  }
 })

<button type="button" class="btn btn-primary" data-page="1" on-click="refesh">查询</button>

init: function () {
    this.extend(PageController)
   },
   created: function () {
    //TODO
   },

$.controller.extend({
   utils: utils,
   notify: $.notify,
   modal: $.modal,
   http: $.http,
