8 * @class Ext.form.Label
9 * @extends Ext.BoxComponent
13 * @param {Ext.Element/String/Object} config The configuration options. If an element is passed, it is set as the internal
14 * element and its id used as the component id. If a string is passed, it is assumed to be the id of an existing element
15 * and is used as the component id. Otherwise, it is assumed to be a standard config object and is applied to the component.
18 Ext.form.Label = Ext.extend(Ext.BoxComponent, {
20 * @cfg {String} text The plain text to display within the label (defaults to ''). If you need to include HTML
21 * tags within the label's innerHTML, use the {@link #html} config instead.
24 * @cfg {String} forId The id of the input element to which this label will be bound via the standard HTML 'for'
25 * attribute. If not specified, the attribute will not be added to the label.
28 * @cfg {String} html An HTML fragment that will be used as the label's innerHTML (defaults to '').
29 * Note that if {@link #text} is specified it will take precedence and this value will be ignored.

46 * Updates the label's innerHTML with the specified string.
47 * @param {String} text The new label text
48 * @param {Boolean} encode (optional) False to skip HTML-encoding the text when rendering it
49 * to the label (defaults to true which encodes the value). This might be useful if you want to include
50 * tags in the label's innerHTML rather than rendering them as string literals per the default logic.
