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.
+ + +To add custom VTypes specify the vtype validation
+test function, and optionally specify any corresponding error text to display and any keystroke
+filtering mask to apply. For example:
// custom Vtype for vtype:'time'
+var timeTest = /^([1-9]|1[0-9]):([0-5][0-9])(\s[a|p]m)$/i;
+Ext.apply(Ext.form.field.VTypes, {
+ // vtype validation function
+ time: function(val, field) {
+ return timeTest.test(val);
+ },
+ // vtype Text property: The error text to display when the validation function returns false
+ timeText: 'Not a valid time. Must be in the format "12:34 PM".',
+ // vtype Mask property: The keystroke filter mask
+ timeMask: /[\d\s:amp]/i
+});
+Another example:
+ +// custom Vtype for vtype:'IPAddress'
+Ext.apply(Ext.form.field.VTypes, {
+ IPAddress: function(v) {
+ return /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/.test(v);
+ },
+ IPAddressText: 'Must be a numeric IP address',
+ IPAddressMask: /[\d\.]/i
+});
+The keystroke filter mask to be applied on alpha input. Defaults to: +/[a-z_]/i
+The keystroke filter mask to be applied on alpha input. Defaults to: +/[a-z_]/i
+The error text to display when the alpha validation function returns false. Defaults to: +'This field should only contain letters and _'
+The keystroke filter mask to be applied on alphanumeric input. Defaults to: +/[a-z0-9_]/i
+The keystroke filter mask to be applied on alphanumeric input. Defaults to: +/[a-z0-9_]/i
+The error text to display when the alphanumeric validation function returns false. Defaults to: +'This field should only contain letters, numbers and _'
+The keystroke filter mask to be applied on email input. See the email method for +information about more complex email validation. Defaults to: +/[a-z0-9_.-@]/i
+The error text to display when the email validation function returns false. Defaults to: +'This field should be an e-mail address in the format "user@example.com"'
+The function used to validate alpha values
+The function used to validate alpha values
+The value
+true if the RegExp test passed, and false if not.
+The function used to validate alphanumeric values
+The function used to validate alphanumeric values
+The value
+true if the RegExp test passed, and false if not.
+The function used to validate email addresses. Note that this is a very basic validation -- complete +validation per the email RFC specifications is very complex and beyond the scope of this class, although +this function can be overridden if a more comprehensive validation scheme is desired. See the validation +section of the Wikipedia article on email addresses +for additional information. This implementation is intended to validate the following emails: +'barney@example.de', 'barney.rubble@example.com', 'barney-rubble@example.coop', 'barney+rubble@example.com' +.
+The email address
+true if the RegExp test passed, and false if not.
