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