- *- *If a field is configured with a
- *{@link Ext.form.TextField#validator validator}function, - * it will be passed the current field value. The{@link Ext.form.TextField#validator validator}- * function is expected to return boolean true if the value is valid or return a string to - * represent the invalid message if invalid.- 2. Built in Validation - *
- *- *Basic validation is affected with the following configuration properties:
- *- * Validation Invalid Message - *- *{@link Ext.form.TextField#allowBlank allowBlank} {@link Ext.form.TextField#emptyText emptyText}- *{@link Ext.form.TextField#minLength minLength} {@link Ext.form.TextField#minLengthText minLengthText}- *{@link Ext.form.TextField#maxLength maxLength} {@link Ext.form.TextField#maxLengthText maxLengthText}- *- 3. Preconfigured Validation Types (VTypes) - *
- *- *Using VTypes offers a convenient way to reuse validation. If a field is configured with a - *
- *{@link Ext.form.TextField#vtype vtype}, the corresponding {@link Ext.form.VTypes VTypes} - * validation function will be used for validation. If invalid, either the field's - *{@link Ext.form.TextField#vtypeText vtypeText}or the VTypes vtype Text property will be - * used for the invalid message. Keystrokes on the field will be filtered according to the VTypes - * vtype Mask property.- 4. Field specific regex test - *
- *- *Each field may also specify a
- *{@link Ext.form.TextField#regex regex}test. - * The invalid message for this test is configured with - *{@link Ext.form.TextField#regexText regexText}.- Alter Validation Behavior - *
- *- *Validation behavior for each field can be configured:
- *
- *- - *
{@link Ext.form.TextField#invalidText invalidText}: the default validation message to - * show if any validation step above does not provide a message when invalid- - *
{@link Ext.form.TextField#maskRe maskRe}: filter out keystrokes before any validation occurs- - *
{@link Ext.form.TextField#stripCharsRe stripCharsRe}: filter characters after being typed in, - * but before being validated- - *
{@link Ext.form.Field#invalidClass invalidClass}: alternate style when invalid- - *
{@link Ext.form.Field#validateOnBlur validateOnBlur}, - *{@link Ext.form.Field#validationDelay validationDelay}, and - *{@link Ext.form.Field#validationEvent validationEvent}: modify how/when validation is triggered{@link #vtype}currently set for this field (defaults to '').
