8 | * @class Ext.form.VTypes |
---|
9 | * <p>This is a singleton object which contains a set of commonly used field validation functions. |
---|
10 | * The validations provided are basic and intended to be easily customizable and extended.</p> |
---|
11 | * <p>To add custom VTypes specify the <code>{@link Ext.form.TextField#vtype vtype}</code> validation |
---|
12 | * test function, and optionally specify any corresponding error text to display and any keystroke |
---|
13 | * filtering mask to apply. For example:</p> |
---|
14 | * <pre><code> |
---|
15 | // custom Vtype for vtype:'time' |
---|
16 | var timeTest = /^([1-9]|1[0-9]):([0-5][0-9])(\s[a|p]m)$/i; |
---|
17 | Ext.apply(Ext.form.VTypes, { |
---|
18 | // vtype validation function |
---|
19 | time: function(val, field) { |
---|
20 | return timeTest.test(val); |
---|
21 | }, |
---|
22 | // vtype Text property: The error text to display when the validation function returns false |
---|
23 | timeText: 'Not a valid time. Must be in the format "12:34 PM".', |
---|
24 | // vtype Mask property: The keystroke filter mask |
---|
25 | timeMask: /[\d\s:amp]/i |
---|
26 | }); |
---|
27 | * </code></pre> |
---|
28 | * Another example: |
---|
29 | * <pre><code> |
---|
30 | // custom Vtype for vtype:'IPAddress' |
---|
31 | Ext.apply(Ext.form.VTypes, { |
---|
32 | IPAddress: function(v) { |
---|
33 | return /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/.test(v); |
---|
34 | }, |
---|
35 | IPAddressText: 'Must be a numeric IP address', |
---|
36 | IPAddressMask: /[\d\.]/i |
---|
37 | }); |
---|
38 | * </code></pre> |
