9 * @class Ext.form.VTypes
10 * <p>This is a singleton object which contains a set of commonly used field validation functions.
11 * The validations provided are basic and intended to be easily customizable and extended.</p>
12 * <p>To add custom VTypes specify the <code>{@link Ext.form.TextField#vtype vtype}</code> validation
13 * test function, and optionally specify any corresponding error text to display and any keystroke
14 * filtering mask to apply. For example:</p>
16 // custom Vtype for vtype:'time'
17 var timeTest = /^([1-9]|1[0-9]):([0-5][0-9])(\s[a|p]m)$/i;
18 Ext.apply(Ext.form.VTypes, {
19 // vtype validation function
20 time: function(val, field) {
21 return timeTest.test(val);
23 // vtype Text property: The error text to display when the validation function returns false
24 timeText: 'Not a valid time. Must be in the format "12:34 PM".',
25 // vtype Mask property: The keystroke filter mask
26 timeMask: /[\d\s:amp]/i
31 // custom Vtype for vtype:'IPAddress'
32 Ext.apply(Ext.form.VTypes, {
33 IPAddress: function(v) {
34 return /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/.test(v);
36 IPAddressText: 'Must be a numeric IP address',
37 IPAddressMask: /[\d\.]/i
42 Ext.form.VTypes = function(){
43 // closure these in so they are only created once.
44 var alpha = /^[a-zA-Z_]+$/;
45 var alphanum = /^[a-zA-Z0-9_]+$/;
46 var email = /^(\w+)([-+.][\w]+)*@(\w[-\w]*\.){1,5}([A-Za-z]){2,4}$/;
47 var url = /(((https?)|(ftp)):\/\/([\-\w]+\.)+\w{2,3}(\/[%\-\w]+(\.\w{2,})?)*(([\w\-\.\?\\\/+@&#;`~=%!]*)(\.\w{2,})?)*\/?)/i;

55 * section of the <a href="http://en.wikipedia.org/wiki/E-mail_address">Wikipedia article on email addresses</a>
56 * for additional information. This implementation is intended to validate the following emails:<tt>
57 * 'barney@example.de', 'barney.rubble@example.com', 'barney-rubble@example.coop', 'barney+rubble@example.com'
59 * @param {String} value The email address
