/** * A FieldSet is a great way to visually separate elements of a form. It's normally used when you have a form with * fields that can be divided into groups - for example a customer's billing details in one fieldset and their shipping * address in another. A fieldset can be used inside a form or on its own elsewhere in your app. Fieldsets can * optionally have a title at the top and instructions at the bottom. Here's how we might create a FieldSet inside a * form: * * @example * Ext.create('Ext.form.Panel', { * fullscreen: true, * items: [ * { * xtype: 'fieldset', * title: 'About You', * instructions: 'Tell us all about yourself', * items: [ * { * xtype: 'textfield', * name : 'firstName', * label: 'First Name' * }, * { * xtype: 'textfield', * name : 'lastName', * label: 'Last Name' * } * ] * } * ] * }); * * Above we created a {@link Ext.form.Panel form} with a fieldset that contains two text fields. In this case, all * of the form fields are in the same fieldset, but for longer forms we may choose to use multiple fieldsets. We also * configured a {@link #title} and {@link #instructions} to give the user more information on filling out the form if * required. */Ext.define('Ext.form.FieldSet', { extend: 'Ext.Container', xtype: 'fieldset', mixins: [ 'Ext.form.Borders' ], requires: [ 'Ext.Title' ], config: { /** * @cfg {String} title * Optional fieldset title, rendered just above the grouped fields. * * ## Example * * Ext.create('Ext.form.Fieldset', { * fullscreen: true, * * title: 'Login', * * items: [{ * xtype: 'textfield', * label: 'Email' * }] * }); * * @accessor */ title: null, /** * @cfg {String} instructions * Optional fieldset instructions, rendered just below the grouped fields. * * ## Example * * Ext.create('Ext.form.Fieldset', { * fullscreen: true, * * instructions: 'Please enter your email address.', * * items: [{ * xtype: 'textfield', * label: 'Email' * }] * }); * * @accessor */ instructions: null }, autoSize: null, baseCls: Ext.baseCSSPrefix + 'form-fieldset', /** * @private */ applyTitle: function(title) { if (typeof title == 'string') { title = {title: title}; } Ext.applyIf(title, { docked : 'top', cls: this.baseCls + '-title' }); return Ext.factory(title, Ext.Title, this._title); }, /** * @private */ updateTitle: function(newTitle, oldTitle) { if (newTitle) { this.add(newTitle); } if (oldTitle) { this.remove(oldTitle); } }, /** * @private */ getTitle: function() { var title = this._title; if (title && title instanceof Ext.Title) { return title.getTitle(); } return title; }, /** * @private */ applyInstructions: function(instructions) { if (typeof instructions == 'string') { instructions = {title: instructions}; } Ext.applyIf(instructions, { docked : 'bottom', cls: this.baseCls + '-instructions' }); return Ext.factory(instructions, Ext.Title, this._instructions); }, /** * @private */ updateInstructions: function(newInstructions, oldInstructions) { if (newInstructions) { this.add(newInstructions); } if (oldInstructions) { this.remove(oldInstructions); } }, /** * @private */ getInstructions: function() { var instructions = this._instructions; if (instructions && instructions instanceof Ext.Title) { return instructions.getTitle(); } return instructions; }, /** * A convenient method to disable all fields in this FieldSet * @return {Ext.form.FieldSet} This FieldSet */ updateDisabled: function(newDisabled) { this.query('field').forEach(function(field) { field.setDisabled(newDisabled); }); return this; }});
