16 * @class Ext.form.VTypes
17 * <p>This is a singleton object which contains a set of commonly used field validation functions.
18 * The validations provided are basic and intended to be easily customizable and extended.</p>
19 * <p>To add custom VTypes specify the <code>{@link Ext.form.TextField#vtype vtype}</code> validation
20 * test function, and optionally specify any corresponding error text to display and any keystroke
21 * filtering mask to apply. For example:</p>
23 // custom Vtype for vtype:'time'
24 var timeTest = /^([1-9]|1[0-9]):([0-5][0-9])(\s[a|p]m)$/i;
25 Ext.apply(Ext.form.VTypes, {
26 // vtype validation function
27 time: function(val, field) {
28 return timeTest.test(val);
30 // vtype Text property: The error text to display when the validation function returns false
31 timeText: 'Not a valid time. Must be in the format "12:34 PM".',
32 // vtype Mask property: The keystroke filter mask
33 timeMask: /[\d\s:amp]/i
38 // custom Vtype for vtype:'IPAddress'
39 Ext.apply(Ext.form.VTypes, {
40 IPAddress: function(v) {
41 return /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/.test(v);
43 IPAddressText: 'Must be a numeric IP address',
44 IPAddressMask: /[\d\.]/i

50 // closure these in so they are only created once.

59 * The function used to validate email addresses. Note that this is a very basic validation -- complete
60 * validation per the email RFC specifications is very complex and beyond the scope of this class, although
61 * this function can be overridden if a more comprehensive validation scheme is desired. See the validation
62 * section of the <a href="http://en.wikipedia.org/wiki/E-mail_address">Wikipedia article on email addresses</a>
63 * for additional information. This implementation is intended to validate the following emails:<tt>
64 * 'barney@example.de', 'barney.rubble@example.com', 'barney-rubble@example.coop', 'barney+rubble@example.com'
66 * @param {String} value The email address
