Sencha Touch - How to remove/hide popup panel on button click

Question

I have created Panel as bellow

Ext.define('MyApp.view.DatePanel', {
extend: 'Ext.Panel',
alias: 'widget.DatePanel',
config: {
    itemid:'DatePanel',
    modal:true,
    centered: true,
    width:'320px',
    height:'110px',   
    items:[
            {
                xtype: 'datepickerfield',
                label: 'Select date',
                type:'date',
                itemId: 'rptDate',
                value: new Date(),
            },
            {
                xtype:'toolbar',
                docked:'bottom',
                items:[{
                    text:'OK',
                    ui:'confirm',
                    action:'ShowTurnOverReport'
                },
                {
                    text:'Cancel',
                    ui:'confirm',
                    action:'Cancel'
                }

            }
        ]
}

});

I show this panel as Pop-up using bellow code

Ext.Viewport.add({xtype: 'DatePanel'});

Now on Button cancel click i want to hide/remove it

I have tried

Ext.Viewport.remove(Datepanel), 
var pnl = Ext.getCmp('DatePanel');
pnl.hide();

but nothing worked. how can i do this ??

Answer 1

You can do it in multiple ways.

Solution 1:

To use the Ext.getCmp() functionality, you need to have an id property set for your component.

Hence, give an id to your DatePanel like shown below,

Ext.define('MyApp.view.DatePanel', {
extend: 'Ext.Panel',
alias: 'widget.DatePanel',
id:'datepanel',
config: {
     ......
     ......

and then on Cancel button click handler, write the below code ...

{
 text:'Cancel',
 ui:'confirm',
 action:'Cancel'
 listeners : {
     tap : function() {
           var pnl = Ext.getCmp('datepanel');
           pnl.hide();
     }
 }
}

Solution 2:

Since you already defined the itemid property, you can use the following line to get the reference to your component ..

var pnl = Ext.Container.getComponent('DatePanel');
pnl.hide();
