Materialize + Framework not updating select value

[maxflex]

Model value is not updated when material_select() is applied to the <select>.

I've made a fiddle to show you what's going on: http://jsfiddle.net/maxflex/j8xcm7d2/

There are also other people facing the same problem: one, two

[ferchoman09]

I have the same issue with AngularJS.

[MichaelDeBoey]

I have the same problem with Angular 2

[Thanood]

I don't know Vue.js enough but with Aurelia I had to issue a custom event on the jQuery change event to make that work. Maybe it helps.

This seems to work:

new Vue({
    el: 'body',
        ready: function() {
        var suspend = false;
        $('#materialize-select').material_select();
      $('#materialize-select').on('change', function() {
        if (!suspend) {
            suspend = true;
          var event = new CustomEvent('change', {
            detail: 'change',
            bubbles: true
          });
          $(this).get(0).dispatchEvent(event);
        }
      });
    }
})

But only once in this example since the custom change also triggers jQuery's change. You'd have to prevent stack overflow in a cleverer way than me. :smile: (f.i. use a real callback and reset suspend there)

Yes, with Angular I had to do a manual binding. When change the model, I execute a JQuery function to update de select component.

[Thanood]

Well, I guess you could encapsulate that behaviour in a component easily with either Angular, Angular2 or Vue.js :smile:

[MichaelDeBoey]

Can you give the exact code you used @ferchoman09?

[ferchoman09]

of course @MichaelDeBoey

This is my select component:

                        <div class="input-field col s12 m6">
                            <select id="usuario" name="Consecutivo" ng-model="idUsuario" my-material-select>
                              <option value="" disabled selected>Seleccione un usuario</option>
                              <option ng-repeat="usuario in usuarios" value="{{usuario.idusuario}}">{{usuario.usr_login}}</option>
                            </select>
                            <label for="usuario">Usuario</label>
                        </div>  

I use a custom directive:

    .directive("myMaterialSelect", [ "$timeout", function($timeout) {
        return {
            restrict: 'A',
            require : 'ngModel',
            link : function(scope, element, attrs, ngModelCtrl) {
                $(function() {
                    $(element).material_select();

                    //Cambia el modelo cuando cambia el elemento seleccionado
                    $(element).change(function() {
                        ngModelCtrl.$setViewValue($(element).val());
                    });
                });
            }
        }
    }])

And in the controller I am watching the variable that I have in the ng-model of select component:

        $scope.$watch("formCaja.consecutivo.id", function(newValue, oldValue) {
            $timeout(function() {
                $("#consecutivo").val(newValue);
                $("#consecutivo").material_select();
            }, 0);
        });

So, I am simulating the two ways binding. Note that you must call the function "material_select()" every time that changes the collection of your select component.

            $timeout(function() {
                $("#consecutivo").material_select();
            }, 0);

Not the best, but I had to do so. Hope this can help you

[MichaelDeBoey]

Oh you're still using Angular.js, not Angular 2 @ferchoman09?

[ferchoman09]

@MichaelDeBoey Oh! Sorry, is Angular 1.5. :(

[MichaelDeBoey]

No problem @ferchoman09 :smile: It's defo a MaterializeCSS problem with the implementation of the select When using the browser-default class it all works fine so... :worried:

[ferchoman09]

Yes, I hope too that materializecss team improve the select implementation for compatibility with frameworks.

[maxflex]

Every two-way binding framework seems to be affected. There are surely ways to get around this problem, I use a custom directive myself – but yeah, we are waiting for some improvements on this one.

[Sophia-nguyen]

I have the same problem with Angular 2, any solution for this problem?

[tceydeliler]

My problem is little bit different: I have an material-select

1. I select a value and php write this value to database.
2. I populate database as table
3. When I click a row modal open and material-select but cant show selected value. If I use browser-default it works. All I want this When I click on green button Select shows 1024 or whatever in value in table (Bandwidth) in fiddle dont know how can I do this

http://jsfiddle.net/tceydeliler/9j8zzfn6

I think Its called as DOM manupulation.

[ferchoman09]

For change the materializecss select I had to do that:

    $("#idSelect").val(newValue);
    $("#idSelect").material_select();

[tceydeliler]

Where do I use "#idselect" ?

[tceydeliler]

It works. Thnx

[virtualvoid]

@ferchoman09 thanks for the workaround. shame on you authors.

[jmherazo]

In angular2 you can use it:

For get:

$('select').material_select();
$('select').change((e) => {
     this.model[e.currentTarget.name] = e.currentTarget.value;
});

For set:

this.model.gender = 'male'; // or this.model = newValues;
$('select').material_select();

[GreyZact]

@Thanood is on right track just add else.

new Vue({
    el: 'body',
    ready: function() {
        var suspend = false;
        $('#materialize-select').material_select();
        $('#materialize-select').on('change', function() {
            if (!suspend) {
                suspend = true;
                var event = new CustomEvent('change', {
                    detail: 'change',
                    bubbles: true
                });
                $(this).get(0).dispatchEvent(event);
            } else {
                suspend = false;
            }
        });
    }
})

http://jsfiddle.net/GreyZact/qukwodpv/

It even works if there are multiple select objects.

[scote]

Any solution who works with template driven and reactive form in Angular 2?

[H5DevHoward]

@ferchoman09 @virtualvoid Can you guys tell me more about the solution for vue2?thanks!

[MelanyB]

Anybody knows if there's any solution for this using reactive forms in Angular2?

[scote]

You can use https://github.com/sherweb/ng2-materialize. We did a wrap for the select that work on both template driven and reactive forms.

[ograndebe]

Hi guys, i solved using @GreyZact snippet, but i use *.vue templates. And created more productive solution:

let selectGambiCounter = 0;

export default class MyHelper {

    constructor() {
        throw new Error('Esta classe nao pode ser instanciada');
    }
    static gambiSelects () {
        selectGambiCounter = 0;
        $('.material-gambi').off('change');
    $('.material-gambi').on('change', function() {
            selectGambiCounter ++;
            if (selectGambiCounter == 1) {
                let event = new CustomEvent('change', {
                    detail: 'change',
                    bubbles: true
                });
                $(this).get(0).dispatchEvent(event);
                console.log(`trigger ${selectGambiCounter}`);
            } else if (selectGambiCounter >= 2)  {
                selectGambiCounter = 0;
            }
    });
    }
}

In template file I added class material-gambi on my selects

and in JS code:

import MyHelper from '../helpers/MyHelper';

updated() {
    $('select').material_select();

    MyHelper.gambiSelects();
}

Works lazy, but works

[DavHanna]

Any updates on this, please? I'm using Vue.JS and this issue is very frustrating.

[cslingerland]

I wish this were fixed. I can't use my forms the way I want to because of this.

Will look into a solution for this

[bergamamyo-bilgisayar]

in vuejs + axios ajax call is promises logic. you can solve your problem like that...

css regions:

<link type="text/css" rel="stylesheet" href="./node_modules/materialize-css/dist/css/materialize.min.css" media="screen,projection"/>

html regions:

map {{option.name}} Country

---

scripts regions:

`

` ------------------------ and app : methods:{ fetchCountry:function(){ const self=this; this.$http.get("./app/country.json") .then(function(res){ res.data.unshift({name:'Please Select Your Country',code:''}); self.countrylist= res.data; }).then(function(){ $('select').material_select(); // ***** important ****** }) .catch(function(err){ console.log(err); }); }, },

[JazielGuerrero]

Hi, for this issue specific for Vue.JS I created a component that contains a select and handle the add, update options with jQuery, and every time the user changes the selected value it emits the change with the new selected value. Hope it help some people. To not copy the entire code here, I link it.

Code: MaterialSelect.vue

[Dogfalo]

The issue seems to be related to jQuery's trigger('change') event not being caught by Angular. Possible fix is to trigger a change event this way, which seems to fire Angular's own handlers properly. Haven't testing this with other frameworks yet.

  var evt = document.createEvent("HTMLEvents");
    evt.initEvent("change", false, true);
    element.dispatchEvent(evt);

[Luis16287]

Hi, please excuse my english. I found this solution for Angular 2

HTML

<div class="input-field col s8 offset-s2">
                <select id="responsibleUser" class="icons" materialize="material_select" name="responsibleUser" [(ngModel)]="responsibleUser" (ngModelChange)="setResponsibleUser($event)" #responsibleUserRef required 
                [ngClass]="{'validate valid' : responsibleUserRef.valid, 'validate invalid': !responsibleUserRef.valid }"
                [materializeSelectOptions]="responsibleUser">
                  <option value="" disabled selected>Select user</option>
                  <option *ngFor="let user of users; let i = index" value="{{user.UserCode}}"data-icon="user.photo" class="circle left">{{user.lastName}}, {{user.name}}</option>
                </select>
                <label>Users</label>
            </div>

And in the .ts file i have

...
public ResponsibleUser: string;

ngOnInit() {
    ...
    this.ResponsibleUser = '';
    ...
}

setResponsibleUser(user: any) {
    console.log('UserCode selected  >>> ', user);
    this.ResponsibleUser = user;
  } 

@MichaelDeBoey @scote @MelanyB maybe it will help you guys

        });
 }

[master455]

@ferchoman09 (thanks) gave me a clue to update options in a Materialize Select ...

If you need load new options in a Materialize Select:

var new_options = <option value =”0” >Select…</option><option value=”1” >Value 1</option>;

$('#MaterializeSelect).html(new_options); // you could use Append (jQuery Function) if you don’t want delete before options

$("#MaterializeSelect ").material_select(); // This is point, you must execute material_select() function to update Select and show new options. 

[aneesshameed]

The possible solution that I found is to use an input, and attach it to a dropdown content. It works well with vue even when you are dynamically creating dropdown. And its reactive, that you don't have to emit any other event to bind values.

Codepen: https://codepen.io/aaha/project/editor/DGJNLE

<style>
    input{
        cursor: pointer;
    }
    .caret{
        float:right;
        position: relative;
        cursor: pointer;
        top:-50px;
    }
    ul{
      width: 100%;
    }
</style>
<script>
    Vue.component('paper-dropdown', {
            template: '<div> \
                          <div class="input-field">\
                             <input type="text" class="dropdown-button" v-bind:data-activates="_id"\
                              v-bind:value="value"> \
                             <label>{{label}}</label> \
                          </div> \
                          <i class="material-icons caret">arrow_drop_down</i>\
                          <ul v-bind:id="_id" class="dropdown-content"> \
                             <li v-for="item in options" v-on:click="setselected"><a v-bind:value="item">{{item}}</a></li> \
                          </ul>\
                       </div>',

Problem is fixed for me after updating VueJS to 1.0.0-beta.

[andreandyp]

Hello, I've read @nihattunali 's solution and it worked for me. I'm using async/await which are on top of promises, however I will share my code just in case anyone needs it:

async mounted(){
        this.$store.commit("activarEspera");
        try{
            let respuesta = await this.$http.post("/api/v1.0/escuelas", {
                sigla: "IPN"
            });
            respuesta.body.escuelas.forEach(escuela => this.escuelas.push(escuela));

            //These two awaits are important. Both are necessary
            await M.updateTextFields();
            await M.FormSelect.init(document.querySelectorAll("select"));
        }
        catch(respuesta){
            M.toast({
                    html: respuesta.body,
                    displayLength: 1500
                });
        }
        this.$store.commit("desactivarEspera");
    }

Tested on VueJS 2.5.13 and Materialize 1.0.0-rc.2.

[DavidCorral94]

For those who still having problems using MaterializeCSS and AngularJs 1.x, I got a workaround. In my case, I have a select which options are added dynamically with the response of a GET request. In this case, this response is stored in an array in my controller ($scope.groups) and I want to display all this options in my select input form. So:

HTML

<select ng-model="newArticle.group" id="group">
            <option ng-repeat="group in groups" value="{{group._id}}"
                    ng-selected="group.selected == true">{{group.name}}
            </option>
</select>

CONTROLLER JS Here, I perform the GET request, and then I store the response into the array of groups. In order to make then able to select in the select box, I have to set a small timeout and then perform $('#group').formSelect(); to refresh the selectbox.

function getGroups() {
        $http.get("/api/v1/groups")
            .then(function (response) {
                console.log('Groups retrieved');
                $scope.groups.push(...response.data);
                setTimeout(function () {
                    $('#group').find('option[value="0"]').prop('selected', true);
                    $('#group').formSelect();
                }, 2000);
            }, function (error) {
                console.log('Error retrieving groups', error);
                alert("Ups! Ha ocurrido un error al recuperar los grupos, inténtalo de nuevo en unos minutos.");
            });
    }

Hope it helps! :-)

Tested on VueJS 2.5.13 and Materialize 1.0.0-rc.2.

It works for me. What's the drawback about use await inside mounted?

in angular 9: i just added a hack below code in ngAfterViewInit() reason is select initialized before it actually process all options setTimeout(() => { $('select').formSelect(); }, 1000);
