I am trying to replicate the code in "Need simple example: add tabs to widget" on GeoNet but I get: TypeError: Cannot read property 'domNode' of undefined
at Object._createTab (TabContainer.js?wab_dv=2.6:91)
Here are my files:
style.css:
.my-tab-node{
position:absolute !important;
width:100% !important;
height:auto !important;
top:0 !important;
bottom:0 !important;
}
Widget.html:
<div>
<div data-dojo-attach-point="tabIdentify">
<div class="my-tab-node" data-dojo-attach-point="tabNode1">
<h3>London</h3>
<p>London is the capital city of England.</p>
</div>
<div class="my-tab-node" data-dojo-attach-point="tabNode2">
<h3>Paris</h3>
<p>Paris is the capital of France.</p>
</div>
</div>
</div>
Widget.js:
define(['dojo/_base/declare',
'dijit/_WidgetsInTemplateMixin',
'jimu/BaseWidget',
'jimu/dijit/TabContainer',
'jimu/utils',
'dojo/_base/lang',
'dojo/on'],
function(declare,
_WidgetsInTemplateMixin,
BaseWidget,
TabContainer,
utils,
lang,
on) {
return declare([_WidgetsInTemplateMixin, BaseWidget], {
baseClass: "tab",
postCreate: function() {
this.inherited(arguments);
console.log('postCreate');
},
startup: function() {
this.inherited(arguments);
console.log('startup');
this._initTabContainer();
},
_initTabContainer: function() {
console.log('_initTabContainer');
var tabs = [];
tabs.push({
title: 'Tab 1',
content: this.tabNode1
});
tabs.push({
title: 'Tab2',
content: this.tabNode2
});
this.selTab = 'Tab 1';
console.log('before new TabContainer');
this.tabContainer = new TabContainer({
tabs: tabs,
selected: this.selTab
}, this.tabIdentify);
console.log('before this.tabContainer.startup()')
this.tabContainer.startup();
this.own(on(this.tabContainer, 'tabChanged', lang.hitch(this, function(title) {
if (title !== 'Tab 1') {
//do something now that Tab 2 has been selected
}
})));
utils.setVerticalCenter(this.tabContainer.domNode);
}
});
});
Based on the console.log messages that I have included in the above code, it dies in the following section:
this.tabContainer = new TabContainer({
tabs: tabs,
selected: this.selTab
}, this.tabIdentify);
Would you have any suggestions on how I could resolve this?
