Raw Blame History

/**
* A 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.field.TextArea}
* and {@link Ext.form.field.ComboBox}). Has support for empty-field placeholder values (see {@link #emptyText}).
*
* # Validation
*
* The Text field has a useful set of validations built in:
*
* - {@link #allowBlank} for making the field required
* - {@link #minLength} for requiring a minimum value length
* - {@link #maxLength} for setting a maximum value length (with {@link #enforceMaxLength} to add it
* as the `maxlength` attribute on the input element)
* - {@link #regex} to specify a custom regular expression for validation
*
* In addition, custom validations may be added:
*
* - {@link #vtype} specifies a virtual type implementation from {@link Ext.form.field.VTypes} which can contain
* custom validation logic
* - {@link #validator} allows a custom arbitrary function to be called during validation
*
* The details around how and when each of these validation options get used are described in the
* documentation for {@link #getErrors}.
*
* By default, the field value is checked for validity immediately while the user is typing in the
* field. This can be controlled with the {@link #validateOnChange}, {@link #checkChangeEvents}, and
* {@link #checkChangeBuffer} configurations. Also see the details on Form Validation in the
* {@link Ext.form.Panel} class documentation.
*
* # Masking and Character Stripping
*
* Text fields can be configured with custom regular expressions to be applied to entered values before
* validation: see {@link #maskRe} and {@link #stripCharsRe} for details.
*
* # Example usage
*
* @example
* Ext.create('Ext.form.Panel', {
* title: 'Contact Info',
* width: 300,
* bodyPadding: 10,
* renderTo: Ext.getBody(),
* items: [{
* xtype: 'textfield',
* name: 'name',
* fieldLabel: 'Name',
* allowBlank: false // requires a non-empty value
* }, {
* xtype: 'textfield',
* name: 'email',
* fieldLabel: 'Email Address',
* vtype: 'email' // requires value to be a valid email address format
* }]
* });
*
* # Custom Subclasses
*
* This class can be extended to provide additional functionality. The example below demonstrates creating
* a custom search field that uses the HTML5 search input type.
*
* @example
* // A simple subclass of Base that creates a HTML5 search field. Redirects to the
* // searchUrl when the Enter key is pressed.222
* Ext.define('Ext.form.SearchField', {
* extend: 'Ext.form.field.Text',
* alias: 'widget.searchfield',
*
* inputType: 'search',
*
* // Config defining the search URL
* searchUrl: 'http://www.google.com/search?q={0}',
*
* // Add specialkey listener
* initComponent: function() {
* this.callParent();
* this.on('specialkey', this.checkEnterKey, this);
* },
*
* // Handle enter key presses, execute the search if the field has a value
* checkEnterKey: function(field, e) {
* var value = this.getValue();
* if (e.getKey() === e.ENTER && !Ext.isEmpty(value)) {
* location.href = Ext.String.format(this.searchUrl, value);
* }
* }
* });
*
* Ext.create('Ext.form.Panel', {
* title: 'Base Example',
* bodyPadding: 5,
* width: 250,
*
* // Fields will be arranged vertically, stretched to full width
* layout: 'anchor',
* defaults: {
* anchor: '100%'
* },
* items: [{
* xtype: 'searchfield',
* fieldLabel: 'Search',
* name: 'query'
* }],
* renderTo: Ext.getBody()
* });

/**
* Validates a value according to the field's validation rules and returns an array of errors
* for any failing validations. Validation rules are processed in the following order:
*
* 1. **Field specific validator**
*
* A validator offers a way to customize and reuse a validation specification.
* If a field is configured with a `{@link #validator}`
* function, it will be passed the current field value. The `{@link #validator}`
* function is expected to return either:
*
* - Boolean `true` if the value is valid (validation continues).
* - a String to represent the invalid message if invalid (validation halts).
*
* 2. **Basic Validation**
*
* If the `{@link #validator}` has not halted validation,
* basic validation proceeds as follows:
*
* - `{@link #allowBlank}` : (Invalid message = `{@link #blankText}`)
*
* Depending on the configuration of `{@link #allowBlank}`, a
* blank field will cause validation to halt at this step and return
* Boolean true or false accordingly.
*
* - `{@link #minLength}` : (Invalid message = `{@link #minLengthText}`)
*
* If the passed value does not satisfy the `{@link #minLength}`
* specified, validation halts.
*
* - `{@link #maxLength}` : (Invalid message = `{@link #maxLengthText}`)
*
* If the passed value does not satisfy the `{@link #maxLength}`
* specified, validation halts.
*
* 3. **Preconfigured Validation Types (VTypes)**
*
* If none of the prior validation steps halts validation, a field
* configured with a `{@link #vtype}` will utilize the
* corresponding {@link Ext.form.field.VTypes VTypes} validation function.
* If invalid, either the field's `{@link #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**
*
* If none of the prior validation steps halts validation, a field's
* configured `{@link #regex}` test will be processed.
* The invalid message for this test is configured with `{@link #regexText}`
*
* @param {Object} value The value to validate. The processed raw value will be used if nothing is passed.
* @return {String[]} Array of any validation errors
