/** * The `formpanel` is an extension over `fieldpanel` and, in addition to rendering the * proper `form` tag * * presents a set of form fields and provides convenient ways to load and * save data. This component uses an HTML `form` element to contain its fields, unlike * {@link Ext.field.Panel fieldpanel}. As a `form`, this component provides a `submit` * method that can be used to post field data to a server. * * Populating a `formpanel` is the same as with {@link Ext.field.Panel fieldpanel}. The * same method are available for setting data in the form, gather field values and managing * field errors. * * ## Submitting Forms * * Using the {@link Ext.field.Panel fieldpanel} class data can be saved to the server using * the {@link Ext.data.Model!method-save save method} of a record. With `formpanel`, * however, you can use its submit method. * * var panel = Ext.create({ * xtype: 'formpanel', * fullscreen: true, * * controller: 'mycontroller', * * buttons: { * submit: 'onSubmit' * }, * * items: [{ * xtype: 'textfield', * name: 'name', * label: 'Name' * }, { * xtype: 'emailfield', * name: 'email', * label: 'Email' * }, { * xtype: 'passwordfield', * name: 'password', * label: 'Password' * }] * }); * * Ext.define('MyController', { * extend: 'Ext.app.ViewController', * alias: 'controller.mycontroller', * * onSubmit: function () { * var form = this.getView(); * * form.submit({ * url: 'url/to/submit/to', * success: function () { * Ext.Msg.alert('Form submitted successfully!'); * } * }); * } * }); * * In this case we provided the `url` to submit the form to inside the submit call. * Alternatively you can just set the {@link #url} config when you create the form. We can * specify other parameters (see {@link #method!submit} for details), including callback * functions for success and failure. These functions are used to take some action in your * app after your data has been saved to the server side. */Ext.define('Ext.form.Panel', { extend: 'Ext.field.Panel', xtype: 'formpanel', alternateClassName: 'Ext.form.FormPanel', classCls: Ext.baseCSSPrefix + 'formpanel', element: { reference: 'element', tag: 'form', novalidate: 'novalidate' }, /** * @event submit * @preventable * Fires upon successful (Ajax-based) form submission. * @param {Ext.form.Panel} this This FormPanel. * @param {Object} result The result object as returned by the server. * @param {Ext.event.Event} e The event object. */ /** * @event beforesubmit * @preventable * Fires immediately preceding any Form submit action. * Implementations may adjust submitted form values or options prior to execution. * A return value of `false` from this listener will abort the submission * attempt (regardless of `standardSubmit` configuration). * @param {Ext.form.Panel} this This FormPanel. * @param {Object} values A hash collection of the qualified form values to be sent to * the server. * @param {Object} options Additional options (this is only available when * `standardSubmit` is `false`). * @param {Ext.event.Event} e The event object if the form was submitted via a HTML5 * form submit event. */ config: { /** * @cfg {Boolean} enableSubmissionForm * The submission form is generated but never added to the dom.
