026  * <p>An <b>opaque</b> class representing JavaScript client-side objects of the global 
027  * {@link JsClient#HTMLPasswordElement} class.</p>
028  * <p>This class represents a push button 
029  * in an HTML page, or a {@link JsHTMLInputElement} object created with the HTML 
030  * <tt>&lt;input&gt;</tt> tag with its <tt>type</tt> 
031  * attribute of the value "password".</p>
032  * <p>An input element of this class is intended for input of sensitive data, such as 
033  * passwords. The input is masked, as the user types, to prevent bystanders from reading 
034  * the input value over his/her shoulder. Note, however that the user's input is not 
035  * encrypted in any way when the form is submitted, it is sent in clear text. As a 
036  * security precaution, some browsers may prevent script code from reading the {@link JsHTMLInputElement#value} 
037  * property. In other respects, an object of this class behaves like that of {@link JsHTMLTextFieldElement}. 
038  * It triggers the {@link JsHTMLInputElement#onchange} event handler when the user changes 
039  * the displayed value.</p>
