populate comboBox using remote JSON store

[zohaib]

Hi,

I am using first example as per following url

http://www.extjs.com/deploy/dev/exam...rm/combos.html

I have local data store in js file and I want to fetch data from db and show using json.
I am trying to use remote data store using url in data store definition but it is not working.

I have attached all working pages with this thread.

// simple array store
    var store = new Ext.data.ArrayStore({
        fields: ['abbr', 'state', 'nick'],
        data : Ext.exampledata.states // from states.js
    });
	
	
	var dd = new Ext.data.ArrayStore({
	     url: 'states.php',
		fields: ['state'],
		data : Ext.countrydata.states // from states.js
	    
	});	
	

    var remoteJsonStore = new Ext.data.JsonStore({
    fields: ['state'],
	url : 'http://localhost/ComboBoxes_files/states.php',
	data : Ext.countrydata.states 
   });

	
    var combo = new Ext.form.ComboBox({
        store: remoteJsonStore,
        displayField:'state',
        typeAhead: true,
        mode: 'local',
        forceSelection: true,
        triggerAction: 'all',
        emptyText:'Select a state...',
        selectOnFocus:true,
        applyTo: 'local-states'
    });

I check following article

http://www.quizzpot.com/2009/10/comb...-and-remotely/

but with

1.combo box keyword search facility available in local data store.
2.combo box keyword search facility not available in remote data store.

any idea

I want

1.Remote data combo box
2.key word search facility in combo
3.data listing from remote data store.

You don't need
data : Ext.countrydata.states in the remoteJsonstore,
and you need to set mode:'remote' in the ComboBox. Try and see if it works.
