/** * A numeric text field that provides automatic keystroke filtering to disallow non-numeric characters, * and numeric validation to limit the value to a range of valid numbers. The range of acceptable number * values can be controlled by setting the {@link #minValue} and {@link #maxValue} configs, and fractional * decimals can be disallowed by setting {@link #allowDecimals} to `false`. * * By default, the number field is also rendered with a set of up/down spinner buttons and has * up/down arrow key and mouse wheel event listeners attached for incrementing/decrementing the value by the * {@link #step} value. To hide the spinner buttons set `{@link #hideTrigger hideTrigger}:true`; to disable * the arrow key and mouse wheel handlers set `{@link #keyNavEnabled keyNavEnabled}:false` and * `{@link #mouseWheelEnabled mouseWheelEnabled}:false`. See the example below. * * # Example usage * * @example * Ext.create('Ext.form.Panel', { * title: 'On The Wall', * width: 300, * bodyPadding: 10, * renderTo: Ext.getBody(), * items: [{ * xtype: 'numberfield', * anchor: '100%', * name: 'bottles', * fieldLabel: 'Bottles of Beer', * value: 99, * maxValue: 99, * minValue: 0 * }], * buttons: [{ * text: 'Take one down, pass it around', * handler: function() { * this.up('form').down('[name=bottles]').spinDown(); * } * }] * }); * * # Removing UI Enhancements * * @example * Ext.create('Ext.form.Panel', { * title: 'Personal Info', * width: 300, * bodyPadding: 10, * renderTo: Ext.getBody(), * items: [{ * xtype: 'numberfield', * anchor: '100%', * name: 'age', * fieldLabel: 'Age', * minValue: 0, //prevents negative numbers * * // Remove spinner buttons, and arrow key and mouse wheel listeners * hideTrigger: true, * keyNavEnabled: false, * mouseWheelEnabled: false * }] * }); * * # Using Step * * @example * Ext.create('Ext.form.Panel', { * renderTo: Ext.getBody(), * title: 'Step', * width: 300, * bodyPadding: 10, * items: [{ * xtype: 'numberfield', * anchor: '100%', * name: 'evens', * fieldLabel: 'Even Numbers', * * // Set step so it skips every other number * step: 2, * value: 0, * * // Add change handler to force user-entered numbers to evens * listeners: { * change: function(field, value) { * value = parseInt(value, 10); * field.setValue(value + value % 2); * } * } * }] * }); */Ext.define('Ext.form.field.Number', { extend:'Ext.form.field.Spinner', alias: 'widget.numberfield', alternateClassName: ['Ext.form.NumberField', 'Ext.form.Number'], /** * @cfg {RegExp} stripCharsRe * @private */ /** * @cfg {RegExp} maskRe * @private */ /** * @cfg {Boolean} [allowExponential=true] * Set to `false` to disallow Exponential number notation */ allowExponential: true, /** * @cfg {Boolean} [allowDecimals=true] * False to disallow decimal values */ allowDecimals : true, //<locale> /** * @cfg {String} decimalSeparator * Character(s) to allow as the decimal separator.
