/**
|
* @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)$/i;
|
Ext.apply(Ext.form.VTypes, {
|
// vtype validation function
|
time: function(val, field) {
|
return timeTest.test(val);
|
},
|
// vtype Text property: The error text to display when the validation function returns false
|
timeText: 'Not a valid time. Must be in the format "12:34 PM".',
|
// vtype Mask property: The keystroke filter mask
|
timeMask: /[\d\s:amp]/i
|
});
|
* </code></pre>
|
* Another example:
|
* <pre><code>
|
// custom Vtype for vtype:'IPAddress'
|
Ext.apply(Ext.form.VTypes, {
|
IPAddress: function(v) {
|
return /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/.test(v);
|
},
|
IPAddressText: 'Must be a numeric IP address',
|
IPAddressMask: /[\d\.]/i
|
});
|
* </code></pre>
|
* @singleton
