/** * @class Ext.field.Hidden * @extend Ext.field.Text * @xtype hiddenfield * * Hidden fields allow you to easily inject additional data into a {@link Ext.form.Panel form} * without displaying additional fields on the screen. This is often useful for sending * dynamic or previously collected data back to the server in the same request as the * normal form submission. For example, here is how we might set up a form to send * back a hidden userId field: * * @example packages=[ext-react] * import React, { Component } from 'react'; * import { ExtReact, Container, FormPanel, HiddenField } from '@sencha/ext-react'; * * export default class MyExample extends Component { * render() { * return ( * <ExtReact> * <Container layout="center"> * <FormPanel shadow> * <HiddenField * value="123" * name="hide" * /> * </FormPanel> * </Container> * <ExtReact> * ) * } * } * * In the form above we created two fields - a hidden field and a * {@link Ext.field.Checkbox check box field}. Only the check box will be visible, but * both fields will be submitted. Hidden fields cannot be tabbed to - they are removed * from the tab index so when your user taps the next/previous field buttons the hidden * field is skipped over. * * It's easy to read and update the value of a hidden field within a form. Using the * example above, we can get a reference to the hidden field and then set it to a new * value in 2 lines of code: * * var userId = form.down('hiddenfield')[0]; * userId.setValue(1234); */ /** * @cfg {Boolean} [hidden=true] * @hide */
