/** * @class Ext.form.TextField * @extends Ext.form.Field *

Basic text field. Can be used as a direct replacement for traditional text inputs, * or as the base class for more sophisticated input controls (like {@link Ext.form.TextArea} * and {@link Ext.form.ComboBox}).

*

Validation

*

The validation procedure is described in the documentation for {@link #validateValue}.

*

Alter Validation Behavior

*

Validation behavior for each field can be configured:

*
* * @constructor Creates a new TextField * @param {Object} config Configuration options * * @xtype textfield */ Ext.form.TextField = Ext.extend(Ext.form.Field, {
/** * @cfg {String} vtypeText A custom error message to display in place of the default message provided * for the {@link #vtype} currently set for this field (defaults to ''). Note: * only applies if {@link #vtype} is set, else ignored. */
/** * @cfg {RegExp} stripCharsRe A JavaScript RegExp object used to strip unwanted content from the value * before validation (defaults to null). */
/** * @cfg {Boolean} grow true if this field should automatically grow and shrink to its content * (defaults to false) */ grow : false,
/** * @cfg {Number} growMin The minimum width to allow when {@link #grow} = true (defaults * to 30) */ growMin : 30,
/** * @cfg {Number} growMax The maximum width to allow when {@link #grow} = true (defaults * to 800) */ growMax : 800,
/** * @cfg {String} vtype A validation type name as defined in {@link Ext.form.VTypes} (defaults to null) */ vtype : null,
/** * @cfg {RegExp} maskRe An input mask regular expression that will be used to filter keystrokes that do * not match (defaults to null) */ maskRe : null,
/** * @cfg {Boolean} disableKeyFilter Specify true to disable input keystroke filtering (defaults * to false) */ disableKeyFilter : false,
/** * @cfg {Boolean} allowBlank Specify false to validate that the value's length is > 0 (defaults to * true) */ allowBlank : true,
/** * @cfg {Number} minLength Minimum input field length required (defaults to 0) */ minLength : 0,
/** * @cfg {Number} maxLength Maximum input field length allowed by validation (defaults to Number.MAX_VALUE). * This behavior is intended to provide instant feedback to the user by improving usability to allow pasting * and editing or overtyping and back tracking. To restrict the maximum number of characters that can be * entered into the field use {@link Ext.form.Field#autoCreate autoCreate} to add * any attributes you want to a field, for example:

var myField = new Ext.form.NumberField({
    id: 'mobile',
    anchor:'90%',
    fieldLabel: 'Mobile',
    maxLength: 16, // for validation
    autoCreate: {tag: 'input', type: 'text', size: '20', autocomplete: 'off', maxlength: '10'}
});
*/ maxLength : Number.MAX_VALUE,
/** * @cfg {String} minLengthText Error text to display if the {@link #minLength minimum length} * validation fails (defaults to 'The minimum length for this field is {minLength}') */ minLengthText : 'The minimum length for this field is {0}',
/** * @cfg {String} maxLengthText Error text to display if the {@link #maxLength maximum length} * validation fails (defaults to 'The maximum length for this field is {maxLength}') */ maxLengthText : 'The maximum length for this field is {0}',
/** * @cfg {Boolean} selectOnFocus true to automatically select any existing field text when the field * receives input focus (defaults to false) */ selectOnFocus : false,
/** * @cfg {String} blankText The error text to display if the {@link #allowBlank} validation * fails (defaults to 'This field is required') */ blankText : 'This field is required',
/** * @cfg {Function} validator *

A custom validation function to be called during field validation ({@link #validateValue}) * (defaults to null). If specified, this function will be called first, allowing the * developer to override the default validation process.

*

This function will be passed the following Parameters:

*
*

This function is to Return:
