Вы можете попробовать это:
this.searchField = new Ext.form.Text({
displayField: 'name',
valueField: 'name',
editable: true,
forceSelection: true,
triggerAction: 'all',
emptyText: 'Search...',
selectOnFocus: true
});
this.searchButton = new Ext.Button({// The button press will invoke the search action
text: 'Go',
handler: this.searchButtonTap,
scope: this
});
this.topToolbar = new Ext.Toolbar({
items: [
{ xtype: 'spacer' },
this.searchField,
this.searchButton,
{ xtype: 'spacer' },
]
});
searchButtonTap: function () {
var searchText = this.searchField.getValue();
console.log(searchText);
},
