10 * @class Ext.form.Label
\r
11 * @extends Ext.BoxComponent
\r
12 * Basic Label field.
\r
14 * Creates a new Label
\r
15 * @param {Ext.Element/String/Object} config The configuration options. If an element is passed, it is set as the internal
\r
16 * 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
\r
17 * and is used as the component id. Otherwise, it is assumed to be a standard config object and is applied to the component.
\r
19 Ext.form.Label = Ext.extend(Ext.BoxComponent, {
\r
21 * @cfg {String} text The plain text to display within the label (defaults to ''). If you need to include HTML
\r
22 * tags within the label's innerHTML, use the {@link #html} config instead.
\r
25 * @cfg {String} forId The id of the input element to which this label will be bound via the standard HTML 'for'
\r
26 * attribute. If not specified, the attribute will not be added to the label.
\r
29 * @cfg {String} html An HTML fragment that will be used as the label's innerHTML (defaults to '').
\r
30 * Note that if {@link #text} is specified it will take precedence and this value will be ignored.

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