angularjs: change filter options dynamically

Question

What I want is something like this example in the documentation but with a unique input that can play the three roles of filtering by \"any\", \"name\" or \"phone\" properti

Answer 1

Here's another simple approach using radio buttons

<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>

Answer 2

You can define ng-model like: ng-model="search[filter]" to change dynamically to which variable it should be binded (where filter is another $scope variable).

See the fiddle: http://jsfiddle.net/lopisan/vzQKk/1/

You have to add this line to the controller:

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

And change input:

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

Here's one approach - there are probably others.

<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}
        }
    }
};
