All Implemented Interfaces:
Serializable, Control, Stateful
public class LongField
extends NumberField

Provides a Long Field control:   <input type='text'>.

Long Field
LongField will validate the number when the control is processed and invoke the control listener if defined.

The LongField uses a JavaScript onkeypress() integerFilter() method to prevent users from entering invalid characters. To enable number key filtering reference the variables $jsElements and $headElements in your page template. For example: 

 <html>
 <head>
 $headElements
 </head>
 <body>

 $form

 $jsElements
 </body>
 </html>
The LongField has left justified horizontal text alignment, Field.setTextAlign(String).
