Extjs 4.1 How to select first item in combo
this works for me
var combo = Ext.getCmp('myId');
combo.select(combo.getStore().getAt(0));
This should do the trick. You basically need to select the first value, make it re-query so that it can clear the filter and then send focus back to the field (optional):
Ext.onReady(function () {
// The data store containing the list of states
var states = Ext.create('Ext.data.Store', {
fields: ['abbr', 'name'],
data : [
{"abbr":"AK", "name":""},
{"abbr":"AL", "name":"Alabama"},
{"abbr":"AZ", "name":"Arizona"}
]
});
// Create the combo box, attached to the states data store
var combo = Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose State',
store: states,
triggerAction: 'all',
queryMode: 'local',
displayField: 'name',
valueField: 'abbr',
trigger2Cls: 'x-form-clear-trigger',
enableKeyEvents: true,
onTrigger2Click: function (args) {
// Select the first record in the store
this.select(this.getStore().getAt(0));
// Force a re-query to clear the filter
this.doQuery();
// Send focus back to the field
this.focus();
},
tpl: new Ext.XTemplate('<tpl for=".">' + '<li style="height:22px;" class="x-boundlist-item" role="option">' + '{name}' + '</li></tpl>'),
renderTo: Ext.getBody()
});
});
Obviously, the re-query and focus are optional. You could easily remove them from this code.
Alternately, you could use the this.select(this.getStore().getAt(0));
and then do this.blur()
to select it and then immediately get rid of the unpopulated list.
