how get data from a list when i tap 1 item

[rolfiee]

I'm stuck on my list. I do not know how to recieve data from it. I have the following code:



Ext.regModel('Contact', {
fields: ['firstName', 'lastName']
});


var store = new Ext.data.JsonStore({
model : 'Contact',
sorters: 'lastName',


getGroupString : function(record) {
return record.get('lastName')[0];
},


data: [
{firstName: 'Tommy', lastName: 'Maintz'},
{firstName: 'Rob', lastName: 'Dougan'},
{firstName: 'Ed', lastName: 'Spencer'},
{firstName: 'Jamie', lastName: 'Avins'},
{firstName: 'Aaron', lastName: 'Conran'},
{firstName: 'Dave', lastName: 'Kaneda'},
{firstName: 'Michael', lastName: 'Mullany'},
{firstName: 'Abraham', lastName: 'Elias'},
{firstName: 'Jay', lastName: 'Robinson'}
]
});

var list = new Ext.List({
fullscreen: true,

itemTpl : '{firstName} {lastName}',
grouped : true,
store: store,
onItemTap: function(item) {
Ext.Msg.alert('Tap', 'Disclose more info for ' + item.get('firstname'), Ext.emptyFn);
}
});


But item.get('firstname') don't work.

Remove your onItemTap code. That's an internal method that you shouldn't override. What you want to do is to 'listen' for the itemtap event and then have a handler function that runs when this event happens.



var list = new Ext.List({
fullscreen: true,
itemTpl : '{firstName} {lastName}',
grouped : true,
store: store,
listeners : {
itemtap : function(dataview, index, item, e) {
var store = dataview.getStore(),
rec = store.getAt(index);
Ext.Msg.alert('Tap', 'Disclose more info for ' + rec.get('firstName'));
}
}
});


Also, you had a typo with the 'firstName' field. It has a capital 'N' so don't forget that. :)

Could also do something like:



itemtap : function(record,index){
var current = record.store.getAt(index);
Ext.Msg.alert('Tap that','Some info about ' + current.firstName);
}
