Passing data to another view from controller and set a label's value in sencha touch - extjs

Question

I have a controller, and I want to pass a simple string value to the next View.
For that, I am creating the View like this.
var nextView = Ext.create('MyApp.view.NextView', {
content: 'value'
});
Ext.Viewport.add(nextView);
Ext.Viewport.animateActiveItem(nextView, {
type: 'slide',
direction: 'left'
});
On the NextView, I have a label and I want to set the HTML property of the label to the value that I am passing from the controller. ie. value.
My NextView looks like this.
Ext.define('MyApp.view.NextView', {
extend: 'Ext.form.Panel',
config: {
content: 'null',
items: [{
xtype: 'label',
html: 'value'
}]
}
});
I am not sure how to proceed from here. I can't have the NextView as a form. I just need to pass one string value in this situation.
What's the best way to achieve this?

Answer 1

Use initialize method to access config data like this:
Ext.define('MyApp.view.NextView', {
extend: 'Ext.form.Panel',
config: {
content: 'null',
items: [
{
xtype: 'label',
html: 'value'
}
]
},
initialize : function(){
this.callParent();
var val = this.config.content;
this.down('label').setHtml(val);
}
});
PS Feel free to use your favourite selector in down function

I know the question has been answered. But I just digged up a pretty natural way to pass data from controller to a view (using view's constructor). I use this in my integration of web desktop to my app.
In controller, pass data to the constructor of the view as followed:
loiTab = Ext.create('Iip.view.giips.admission.DetailedLoiTab', {closable: true, selectedLoiData: selected[0].data});
In the view, spin up a constructor as followed:
constructor: function(selectedLoiData) {
Ext.applyIf(this, selectedLoiData);
this.callParent();
},
The following method lives in the same file as the constructor. You can access selectedLoiData from any where in the view the constructor lives as followed:
initComponent: function(){
console.log(this.selectedLoiData);
}
