Adding values to dijit/form/ComboBox

MargaRaiz — Mon, 29 Aug 2016 11:03:44 GMT

Hello!

I am learning wab and dojo and trying to load some values in a combo box that is defined in the widget.html:

widget.html:

widget.js:

node = dojo.byId("listcity");

              var elOptNew = document.createElement('option');
              elOptNew.text = "city1";
              elOptNew.value = 1;

node.add(elOptNew);

              elOptNew = document.createElement('option');
              elOptNew.text = "city2";
              elOptNew.value = 2;

node.add(elOptNew);

This works fine for me, but I think that there are other ways with the stores to do the same.. Any help?

Thanks in advance!

Marga

Marga,

All you need is to add the necessary requires and code:

Widget.js

...
'dojo/store/Memory',
...
],
 function(
...
Memory,
...

var cities = [
  {
    name: "city1",
    value: 1
  }, {
    name: "city2",
    value: 2
  }
];
myStore = new Memory({
    data: cities
});
this.citycombo.set('store', myStore);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Widget.html

<div data-dojo-attach-point="cityCombo" data-dojo-type="dijit/form/FilteringSelect"
 data-dojo-props="searchAttr:'name',intermediateChanges:true" class="dijit-form-FilteringSelect"></div>‍‍

Hi Robert!

Thanks for the quick answer, but this piece of code does not work 😞

Widget.js

define(['dojo/_base/declare',
'dojo/store/Memory',
'jimu/BaseWidget',
'dojo/dom'],
function (declare, Memory, BaseWidget, dom) {
    //To create a widget, you need to derive from BaseWidget.
    return declare([BaseWidget], {
      // Custom widget code goes here

baseClass: 'jimu-widget-mywidget',

       startup: function() {
        this.inherited(arguments);
        //this.mapIdNode.innerHTML = 'map id is:' + this.map.id;
        console.log('startup');

        var cities = [
            {
            name: "city1",
            value: 1
            },
            {
            name: "city2",
            value: 2
            }
            ];
         myStore = new Memory({data: cities});

this.cityCombo.set('store', myStore);
console.log('end');

}

});
});

widget.html

but.. when I tried from my app, I get this error in de firebug..

TypeError: this.cityCombo.set is not a function

this.cityCombo.set('store', myStore);

I have tried with "put" function, with "dom.byId" but I am not able to make it works.

Any idea?

Thanks!

Marga

Marga,

When you use widgets in the html template you must include the require for _WidgetsInTemplateMixin and declare it as well in the Widget.js. You also need to require the specific dijit or widget that you are including in the template:

Widget.js: (lines 3,6,7,9)

define(['dojo/_base/declare',
'dojo/store/Memory',
'dijit/_WidgetsInTemplateMixin',
'jimu/BaseWidget',
'dojo/dom',
'dijit/form/FilteringSelect'],
  function (declare, Memory, _WidgetsInTemplateMixin, BaseWidget, dom) {
    //To create a widget, you need to derive from BaseWidget.
    return declare([BaseWidget, _WidgetsInTemplateMixin], {
      // Custom widget code goes here
      baseClass: 'jimu-widget-mywidget',
 
       startup: function() {
        this.inherited(arguments);
        //this.mapIdNode.innerHTML = 'map id is:' + this.map.id;
        console.log('startup');

        var cities = [
            {
            name: "city1",
            value: 1
            },
            {
            name: "city2",
            value: 2
            }
            ];
         myStore = new Memory({data: cities});

        this.cityCombo.set('store', myStore);
        console.log('end');
       }

    });
  });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Widget.html:

<div>
  <div data-dojo-attach-point="cityCombo" data-dojo-type="dijit/form/FilteringSelect"
   data-dojo-props="searchAttr:'name',intermediateChanges:true" class="dijit-form-FilteringSelect"></div>
</div>‍‍‍‍
