A combobox control with support for autocomplete, remote-loading, paging and many other features.
- *A ComboBox works in a similar manner to a traditional HTML <select> field. The difference is - * that to submit the {@link #valueField}, you must specify a {@link #hiddenName} to create a hidden input - * field to hold the value of the valueField. The {@link #displayField} is shown in the text field - * which is named according to the {@link #name}.
- *Events
- *To do something when something in ComboBox is selected, configure the select event:
-var cb = new Ext.form.ComboBox({
- // all of your config options
- listeners:{
- scope: yourScope,
- 'select': yourFunction
- }
-});
-
-// Alternatively, you can assign events after the object is created:
-var cb = new Ext.form.ComboBox(yourOptions);
-cb.on('select', yourFunction, yourScope);
- *
- *
- * ComboBox in Grid
- *If using a ComboBox in an {@link Ext.grid.EditorGridPanel Editor Grid} a {@link Ext.grid.Column#renderer renderer} - * will be needed to show the displayField when the editor is not active. Set up the renderer manually, or implement - * a reusable render, for example:
-// create reusable renderer
-Ext.util.Format.comboRenderer = function(combo){
- return function(value){
- var record = combo.findRecord(combo.{@link #valueField}, value);
- return record ? record.get(combo.{@link #displayField}) : combo.{@link #valueNotFoundText};
- }
-}
-
-// create the combo instance
-var combo = new Ext.form.ComboBox({
- {@link #typeAhead}: true,
- {@link #triggerAction}: 'all',
- {@link #lazyRender}:true,
- {@link #mode}: 'local',
- {@link #store}: new Ext.data.ArrayStore({
- id: 0,
- fields: [
- 'myId',
- 'displayText'
- ],
- data: [[1, 'item1'], [2, 'item2']]
- }),
- {@link #valueField}: 'myId',
- {@link #displayField}: 'displayText'
-});
-
-// snippet of column model used within grid
-var cm = new Ext.grid.ColumnModel([{
- ...
- },{
- header: "Some Header",
- dataIndex: 'whatever',
- width: 130,
- editor: combo, // specify reference to combo instance
- renderer: Ext.util.Format.comboRenderer(combo) // pass combo instance to reusable renderer
- },
- ...
-]);
