How to use ng-options.

$scope.fieldTable = [
    { 
        filed:"text",
        title:"Global"
    },
    {
        field: "relatedentity",
        title: "Entity"
    },
    {
        field:"title",
        title:"Title"
    },
    {
        field: "content",
        title: "Content"
    }
]

I want to build a which use the title as displayed and when select something, popout a alert window which display the according field. The initial selection is

{ 
    filed:"text",
    title:"Global"
}

Can anyone help?

var app = angular.module('stack', []);

app.controller('MainCtrl', function($scope) {
  $scope.fieldTable = [{
    field: "text",
    title: "Global"
  }, {
    field: "relatedentity",
    title: "Entity"
  }, {
    field: "title",
    title: "Title"
  }, {
    field: "content",
    title: "Content"
  }];

   $scope.selected = $scope.fieldTable[0];

  $scope.hasChanged = function() {
alert($scope.selected.field);
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<body ng-app="stack" ng-controller="MainCtrl">
   <select ng-options="item.title for item in fieldTable" ng-model="selected" ng-change="hasChanged()">
  </select>
</body>

You can use ng-change to do that

<select ng-options="item.title as item.title for item in fieldTable track by item.title" ng-model="selected" ng-change="onChanged()">

then in your onChange() method in the controller you can do whatever you want it to do :) In your case , show an alert with the value
