/** * @aside guide forms * * This is a specialized field which shows a {@link Ext.picker.Date} when tapped. If it has a predefined value, * or a value is selected in the {@link Ext.picker.Date}, it will be displayed like a normal {@link Ext.field.Text} * (but not selectable/changable). * * Ext.create('Ext.field.DatePicker', { * label: 'Birthday', * value: new Date() * }); * * {@link Ext.field.DatePicker} fields are very simple to implement, and have no required configurations. * * ## Examples * * It can be very useful to set a default {@link #value} configuration on {@link Ext.field.DatePicker} fields. In * this example, we set the {@link #value} to be the current date. You can also use the {@link #setValue} method to * update the value at any time. * * @example miniphone preview * Ext.create('Ext.form.Panel', { * fullscreen: true, * items: [ * { * xtype: 'fieldset', * items: [ * { * xtype: 'datepickerfield', * label: 'Birthday', * name: 'birthday', * value: new Date() * } * ] * }, * { * xtype: 'toolbar', * docked: 'bottom', * items: [ * { xtype: 'spacer' }, * { * text: 'setValue', * handler: function() { * var datePickerField = Ext.ComponentQuery.query('datepickerfield')[0]; * * var randomNumber = function(from, to) { * return Math.floor(Math.random() * (to - from + 1) + from); * }; * * datePickerField.setValue({ * month: randomNumber(0, 11), * day : randomNumber(0, 28), * year : randomNumber(1980, 2011) * }); * } * }, * { xtype: 'spacer' } * ] * } * ] * }); * * When you need to retrieve the date from the {@link Ext.field.DatePicker}, you can either use the {@link #getValue} or * {@link #getFormattedValue} methods: * * @example preview * Ext.create('Ext.form.Panel', { * fullscreen: true, * items: [ * { * xtype: 'fieldset', * items: [ * { * xtype: 'datepickerfield', * label: 'Birthday', * name: 'birthday', * value: new Date() * } * ] * }, * { * xtype: 'toolbar', * docked: 'bottom', * items: [ * { * text: 'getValue', * handler: function() { * var datePickerField = Ext.ComponentQuery.query('datepickerfield')[0]; * Ext.Msg.alert(null, datePickerField.getValue()); * } * }, * { xtype: 'spacer' }, * { * text: 'getFormattedValue', * handler: function() { * var datePickerField = Ext.ComponentQuery.query('datepickerfield')[0]; * Ext.Msg.alert(null, datePickerField.getFormattedValue()); * } * } * ] * } * ] * }); * * */ Ext.define('Ext.field.DatePicker', { extend: 'Ext.field.Text', alternateClassName: 'Ext.form.DatePicker', xtype: 'datepickerfield', requires: [ 'Ext.picker.Date', 'Ext.DateExtras' ], /** * @event change * Fires when a date is selected * @param {Ext.field.DatePicker} this * @param {Date} date The new date */ config: { ui: 'select', /** * @cfg {Object/Ext.picker.Date} picker * An object that is used when creating the internal {@link Ext.picker.Date} component or a direct instance of {@link Ext.picker.Date} * Defaults to true * @accessor */ picker: true, /** * @cfg {Boolean} * @hide * @accessor */ clearIcon: false, /** * @cfg {Object/Date} value * Default value for the field and the internal {@link Ext.picker.Date} component.
