我想要的是类似于文档中的这个示例，但是具有唯一的输入，可以通过“任何”、“名称”或“电话”属性发挥过滤的三个角色，角色的更改是通过锚点单击完成的。这是准备好的代码http://jsfiddle.net/ubugnu/QuyCU/如何动态更新 ng-model 属性？

HTML

<div ng-app>
  <div ng-controller="MainCtrl">

      <label>Any</label> <input type="text" ng-model="search.$"> <br>
      <label>Name only</label> <input type="text" ng-model="search.name"><br>
      <label>Phone only</label> <input type="text" ng-model="search.phone"><br>

      <div style="background-color:#FAE8F1">
      <hr>

      <label>Filter</label> <input type="text" ng-model="search.$"> by {{filter}} <br>
      <ul>
      <li><a href="" ng-click="changeFilterTo('$')">Any</a></li>
      <li><a href="" ng-click="changeFilterTo('name')">By Name</a></li>
      <li><a href="" ng-click="changeFilterTo('phone')">By phone</a></li>
      </ul>

      <hr>
      </div>

      <table class="table">
        <tr><th>Name</th><th>Phone</th></tr>
        <tr ng-repeat="friend in friends | filter:search">
          <td>{{friend.name}}</td>
          <td>{{friend.phone}}</td>
        </tr>
      </table>
  </div>
</div>

JS

function MainCtrl($scope, $http) {
    $scope.friends = [{name:'John', phone:'555-1276'},
                      {name:'Mary', phone:'800-BIG-MARY'},
                      {name:'Mike', phone:'555-4321'},
                      {name:'Adam', phone:'555-5678'},
                      {name:'Julie', phone:'555-8765'}];
    $scope.filter = "$";
    $scope.changeFilterTo = function(pr) {
        $scope.filter = pr; 
    }
};

您可以定义ng-model如下：ng-model="search[filter]"动态更改它应该绑定的变量（filter另一个$scope变量在哪里）。

见小提琴：http: //jsfiddle.net/lopisan/vzQKk/1/

您必须将此行添加到控制器：

$scope.search = {name:'', phone:'', $:''};

并更改输入：

<input type="text" ng-model="search[filter]">

这是一种方法 - 可能还有其他方法。

<div ng-app>
  <div ng-controller="MainCtrl">
      <div style="background-color:#FAE8F1">
      <hr>

      <label>Filter</label> <input type="text" ng-model="multi"> by {{filter}}         <br>
      <ul>
      <li><a href="" ng-click="changeFilterTo('$')">Any</a></li>
      <li><a href="" ng-click="changeFilterTo('name')">By Name</a></li>
      <li><a href="" ng-click="changeFilterTo('phone')">By phone</a></li>
      </ul>

      <hr>
      </div>

      <table class="table">
        <tr><th>Name</th><th>Phone</th></tr>
        <tr ng-repeat="friend in friends | filter:getFilter()">
          <td>{{friend.name}}</td>
          <td>{{friend.phone}}</td>
        </tr>
      </table>
  </div>
</div>

Javascript：

function MainCtrl($scope, $http) {
    $scope.friends = [{name:'John', phone:'555-1276'},
                      {name:'Mary', phone:'800-BIG-MARY'},
                      {name:'Mike', phone:'555-4321'},
                      {name:'Adam', phone:'555-5678'},
                      {name:'Julie', phone:'555-8765'}];
    $scope.filter = "$";
    $scope.multi = "";
    $scope.changeFilterTo = function(pr) {
        $scope.filter = pr; 
    }
    $scope.getFilter = function() {
        switch ($scope.filter) {
            case 'name':
                return {name: $scope.multi};
            case 'phone':
                return {phone: $scope.multi};
            default:
                return {$: $scope.multi}
        }
    }
};

这是使用单选按钮的另一种简单方法

<input type="text" ng-model="search[filter]">

<label>filter by these</label>

<label>Any <input type="radio" ng-model="filter" ng-init="filter = '$'" value="$"></label>
<label>name<input type="radio" ng-model="filter" value="name"></label>
<label>phone<input type="radio" ng-model="filter" value="phone"></label>
