截止目前最新的Ext-4.2.1.883版本，分別提供日期組件（xtype:'datefield'）和時間組件（xtype:'timefield'）,卻沒有提供日期+時分秒組件。
搜索到的牛人擴展組件代碼貼下：
1、新建時間選擇器上的時分秒輸入框類TimePickerField.js
/**
* 時間輸入框, 三個整數框分別輸入時,分,秒.

* update Ext - 4.1 2012/04/27
*/
Ext.define('MyApp.ux.TimePickerField', {
extend: 'Ext.form.field.Base',
alias: 'widget.timepicker',
alternateClassName: 'Ext.form.field.TimePickerField',
requires: ['Ext.form.field.Number'],
// 隱藏BaseField的輸入框 , hidden basefield's input
inputType: 'hidden',
style: 'padding:4px 0 0 0;margin-bottom:0px',
/**
* @cfg {String} value
* initValue, format: 'H:i:s'
*/
value: null,
/**

* 數字輸入框參數, number input config
*/
spinnerCfg: {
width: 40
},
/** Override. */
initComponent: function() {
var me = this;
me.value = me.value || Ext.Date.format(new Date(), 'H:i:s');
me.callParent();// called setValue
me.spinners = [];
var cfg = Ext.apply({}, me.spinnerCfg, {
readOnly: me.readOnly,
disabled: me.disabled,
style: 'float: left',
listeners: {
change: {
fn: me.onSpinnerChange,
scope: me
}
}
});
me.hoursSpinner = Ext.create('Ext.form.field.Number', Ext.apply({}, cfg, {
minValue: 0,
maxValue: 23
}));
me.minutesSpinner = Ext.create('Ext.form.field.Number', Ext.apply({}, cfg, {
minValue: 0,
maxValue: 59
}));
// TODO 使用timeformat 判斷是否創建秒輸入框, maybe second field is not always need.
me.secondsSpinner = Ext.create('Ext.form.field.Number', Ext.apply({}, cfg, {
minValue: 0,
maxValue: 59
}));
me.spinners.push(me.hoursSpinner, me.minutesSpinner, me.secondsSpinner);
},
/**

* Override.
*/
onRender: function() {
var me = this, spinnerWrapDom, spinnerWrap;
me.callParent(arguments);
// render to original BaseField input td
// spinnerWrap = Ext.get(Ext.DomQuery.selectNode('div', this.el.dom)); // 4.0.2
spinnerWrapDom = Ext.dom.Query.select('td', this.getEl().dom)[1]; // 4.0 ->4.1 div->td
spinnerWrap = Ext.get(spinnerWrapDom);
me.callSpinnersFunction('render', spinnerWrap);
Ext.core.DomHelper.append(spinnerWrap, {
tag: 'div',
cls: 'x-form-clear-left'
});
this.setRawValue(this.value);
},
_valueSplit: function(v) {
if(Ext.isDate(v)) {
v = Ext.Date.format(v, 'H:i:s');
}
var split = v.split(':');
return {
h: split.length > 0 ? split[0] : 0,
m: split.length > 1 ? split[1] : 0,
s: split.length > 2 ? split[2] : 0
};
},
onSpinnerChange: function() {
if(!this.rendered) {
return;
}
this.fireEvent('change', this, this.getValue(), this.getRawValue());
},
// 依次調用各輸入框函數, call each spinner's function
callSpinnersFunction: function(funName, args) {
for(var i = 0; i < this.spinners.length; i++) {
this.spinners[i][funName](args);
}
},
// @private get time as object,
getRawValue: function() {
if(!this.rendered) {
var date = this.value || new Date();
return this._valueSplit(date);
} else {
return {
h: this.hoursSpinner.getValue(),
m: this.minutesSpinner.getValue(),
s: this.secondsSpinner.getValue()
};
}
},
// private
setRawValue: function(value) {
value = this._valueSplit(value);
if(this.hoursSpinner) {
this.hoursSpinner.setValue(value.h);
this.minutesSpinner.setValue(value.m);
this.secondsSpinner.setValue(value.s);
}
},
// overwrite
getValue: function() {
var v = this.getRawValue();
return Ext.String.leftPad(v.h, 2, '0') + ':' + Ext.String.leftPad(v.m, 2, '0') + ':'
+ Ext.String.leftPad(v.s, 2, '0');
},

&& this.secondsSpinner.isValid(preventMark);
},
// overwrite
validate: function() {
return this.hoursSpinner.validate() && this.minutesSpinner.validate() && this.secondsSpinner.validate();
}
});2、將日期選擇器datepicker組件擴展成日期時分秒選擇器datetimepicker：
Ext.define('MyApp.ux.DateTimePicker', {
extend: 'Ext.picker.Date',
alias: 'widget.datetimepicker',
todayText: '現在',
timeLabel: '時間',
requires: ['MyApp.ux.TimePickerField'],
initComponent: function() {
// keep time part for value
var value = this.value || new Date();
this.callParent();
this.value = value;
},
onRender: function(container, position) {
if(!this.timefield) {
this.timefield = Ext.create('MyApp.ux.TimePickerField', {
fieldLabel: this.timeLabel,
labelWidth: 40,
value: Ext.Date.format(this.value, 'H:i:s')
});
}
this.timefield.ownerCt = this;
this.timefield.on('change', this.timeChange, this);
this.callParent(arguments);
var table = Ext.get(Ext.DomQuery.selectNode('table', this.el.dom));
var tfEl = Ext.core.DomHelper.insertAfter(table, {
tag: 'div',
style: 'border:0px;',
children: [{
tag: 'div',
cls: 'x-datepicker-footer ux-timefield'
}]
}, true);
this.timefield.render(this.el.child('div div.ux-timefield'));
var p = this.getEl().parent('div.x-layer');
if(p) {
p.setStyle("height", p.getHeight() + 31);
}
},
// listener 時間域修改, timefield change
timeChange: function(tf, time, rawtime) {
// if(!this.todayKeyListener) { // before render
this.value = this.fillDateTime(this.value);
// } else {
// this.setValue(this.value);
// }
},
// @private
fillDateTime: function(value) {
if(this.timefield) {
var rawtime = this.timefield.getRawValue();
value.setHours(rawtime.h);
value.setMinutes(rawtime.m);
value.setSeconds(rawtime.s);
}
return value;
},
// @private
changeTimeFiledValue: function(value) {
this.timefield.un('change', this.timeChange, this);
this.timefield.setValue(this.value);
this.timefield.on('change', this.timeChange, this);
},
/* TODO 時間值與輸入框綁定, 考慮: 創建this.timeValue 將日期和時間分開保存. */
// overwrite
setValue: function(value) {
this.value = value;
this.changeTimeFiledValue(value);
return this.update(this.value);
},
// overwrite
getValue: function() {
return this.fillDateTime(this.value);
},
// overwrite : fill time before setValue
handleDateClick: function(e, t) {
var me = this,
handler = me.handler;
e.stopEvent();
if(!me.disabled && t.dateValue && !Ext.fly(t.parentNode).hasCls(me.disabledCellCls)) {
me.doCancelFocus = me.focusOnSelect === false;
me.setValue(this.fillDateTime(new Date(t.dateValue))); // overwrite: fill time before setValue
delete me.doCancelFocus;
me.fireEvent('select', me, me.value);
if(handler) {
handler.call(me.scope || me, me, me.value);
}
me.onSelect();
}
},
// overwrite : fill time before setValue
selectToday: function() {
var me = this,
btn = me.todayBtn,
handler = me.handler;
if(btn && !btn.disabled) {
// me.setValue(Ext.Date.clearTime(new Date())); //src
me.setValue(new Date());// overwrite: fill time before setValue
me.fireEvent('select', me, me.value);
if(handler) {
handler.call(me.scope || me, me, me.value);
}
me.onSelect();
}
return me;
}
});2、引用日期時分秒選擇器datetimepicker，將日期datefield組件擴展成日期時分秒datetimefield組件：
Ext.Loader.setConfig({enabled:true});
Ext.Loader.setPath('MyApp', '../houtai/js');
Ext.define('MyApp.ux.DateTimeField', {
extend: 'Ext.form.field.Date',
alias: 'widget.datetimefield',
requires: ['MyApp.ux.DateTimePicker'],
initComponent: function() {
this.format = this.format;
this.callParent();
},
// overwrite
createPicker: function() {
var me = this,
format = Ext.String.format;
return Ext.create('MyApp.ux.DateTimePicker', {
ownerCt: me.ownerCt,
renderTo: document.body,
floating: true,
hidden: true,
focusOnShow: true,
minDate: me.minValue,
maxDate: me.maxValue,
disabledDatesRE: me.disabledDatesRE,
disabledDatesText: me.disabledDatesText,
disabledDays: me.disabledDays,
disabledDaysText: me.disabledDaysText,
format: me.format,
showToday: me.showToday,
startDay: me.startDay,
minText: format(me.minText, me.formatDate(me.minValue)),
maxText: format(me.maxText, me.formatDate(me.maxValue)),
listeners: {
scope: me,
select: me.onSelect
},
keyNavConfig: {
esc: function() {
me.collapse();
}
}
});
}
});3、在form中使用xtype：datetimefield，首先引入擴展類：
requires:'MyApp.ux.DateTimeField',
具體使用：
{
xtype:'datetimefield',
width : 300,
labelWidth : 80,
endDateField:'etime',
vtype:'daterange',
fieldLabel: '記錄時間下限',
format: 'Y-m-d H:i:s ',
name:'stime'
},
{
xtype:'datetimefield',
width : 300,
labelWidth : 80,
startDateField:'stime',
vtype:'daterange',
fieldLabel: '記錄時間上限',
format: 'Y-m-d H:i:s ',
name:'etime'
},4、頁面效果：
5、使用體驗：
可實現日期時分秒的選擇輸入，但操作體驗略差強人意。如：選擇器上只有'現在'按鈕,若增加‘確定’按鈕，點擊後選擇器消失，日期時分秒值填入框體就好了。現在選非'現在'的精確時間，最後需以點擊日期結束，框體中的年月日時分秒才與選擇器中完全一致。
