AngularJs: Bind ui-select from Json and filter table

Question

Using AngularJS 1.3.4.

I have a html table that is being populated from an web api where I make an http request to get that data and populate my html table. My example json is as below:

{
    id: 1,
    firstName: "John",
    lastName: "Rein",
    status: 'available'
},
{
    id: 2,
    firstName: "David",
    lastName: "Gumry",
     status: 'not available'
}

Now I have a dropdown below the table, and I am using ui-select for it. I want to populate this dropdown based on the status in my json. For example in my json above I have 2 status available and not available. I want my dropdown to have these values. After I populate my dropdown, I want to filter my table based on the dropdown value that is selected. I have my dropdown as:

  <ui-select tagging ng-model="selected" theme="bootstrap">
    <ui-select-match placeholder="Pick one...">{{$select.selected.value}}</ui-select-match>
    <ui-select-choices repeat="val in values | filter: $select.search track by val.value">
        <div ng-bind="val.value | highlight: $select.search"></div>
    </ui-select-choices>        
</ui-select>

I have created my jsfiddle at: https://jsfiddle.net/aman1981/wfL1374x/

I am not sure how can I bind the results from json to my DDL and filter my table.

The link to your jsfiddle is broken

You had a few issues that needed handling including redundant use of ng-app and ng-controller. Also, it seems as though ui-select works best using the ControllerAs syntax which is a preferred approach in general.

After these changes and others (too many to list), here's the working code:

angular.module('myApp', ['ui.select'])

  .controller("PeopleCtrl", function($http) {

    var vm = this;

    vm.people = [];
    vm.isLoaded = false;
    vm.values = [];

    vm.loadPeople = function() {
      // *** I had to comment this out as it is not allowed in the SO Code Snippet but is fine for your code
      //$http({
      //  method: 'POST',
      //  url: '/echo/json/',
      //  data: mockDataForThisTest

      //}).then(function(response, status) {
      //  console.log(response.data);
      //  vm.people = response.data;
      //});
      vm.people = [{
          id: 1,
          firstName: "John",
          lastName: "Rein",
          status: 'available'
        },
        {
          id: 2,
          firstName: "David",
          lastName: "Gumry",
          status: 'not available'
        }
      ];

      vm.values = [...new Set(vm.people.map(obj => ({
        value: obj.status
      })))];
    };

    vm.selected = {
      key: null,
      value: null
    };

    var mockDataForThisTest = "json=" + encodeURI(JSON.stringify([{
        id: 1,
        firstName: "John",
        lastName: "Rein",
        status: 'available'
      },
      {
        id: 2,
        firstName: "David",
        lastName: "Gumry",
        status: 'not available'
      }
    ]));
  })

thank for this. I had mentioned that the dropdown needs to be populated from the json itself, not the hardcoded values. I had created with hardcoded values as I dont know how to populate that from json. Sorry if I was not clear.

I’m not sure what more you are looking for. You have an $http call to get the data. What else are you needing?

aman Over a year ago

The ui-select is bind to repeat="val in ctrl.values" where values are hardcoded array in the controller. Since My json has "Status" as on of the key. I want my dropdown to bind to status from the Json not the hard coded Values array. Hope its clear now

aman Over a year ago

is this doable?

jbrown Over a year ago

Are you asking if the values array can be initialized with data from the peoples array?
