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.
