Fire 'tel' link from button in Sencha Touch

问题

I have an ActionSheet which is shown when a user taps on a list item. In the ActionSheet are three buttons - one to remove the contact, one to make a call to them and one to dismiss the ActionSheet. My question is, how do I bind the equivalent of a <a href="tel:000000000"></a> to the button?

I need to specify the 'tel:' protocol so that iOS and Android will force the Phone application to load with this number?

It's pretty simple,

All you have to do is change the document's location (window element) in the button's handler:

        var tapHandler = function(button, event){
            Ext.Msg.confirm('External Link', 'Call ' + button.contactName + "?", function(res){
                if (res == 'yes') {
                    window.location = button.callUrl;
                }
            }, this);

        };


        var callButton = new Ext.Button({
            text: 'Call Now',
            callUrl: 'tel:995223423',
            contactName: 'Ben M',
            handler: tapHandler
        });

Haven't tried this, but if Rubinsh's method doesn't work try creating it programmatically in the button's click handler.

function(){
   var alink = Ext.getBody().createChild({tag: 'a', href: 'tel:#########'});
   var event = document.createEvent("TouchEvent");
   event.initTouchEvent('tap', true, true, window, 0, 0, 0, 0);
   alink.dispatchEvent(event);
}
