最近在做一个case的时候，客户要求能在选择年月日，时分秒在一个面板中选择；客户端JS框架使用的是ExtJs4.2。
我们知道，ExtJs4.2的Ext.picker.Date只能选择年月日，网上有部分实现，但大多数的都是基于ExtJs3修改的，而且过多的破坏了ExtJs的编写习惯。
现将我写的跟大家分享下，代码中有相关注释，目前还不支持minValue和maxValue设置。
顺便提下，官方示例中的时间区间的vtype扩展在2个日历控件都设置了value情况下会陷入无限的validate校验，从而导致浏览器崩溃。

1、自定义DateTime选择器：
/*

Ext.define('Go.picker.DateTime', {

okText:'确定',//确认按钮文字描述
okTip:'确定',//确认按钮提示内容

//在组件渲染之前，将自定义添加的时、分、秒和确认按钮进行初始化
//组件宽度可能需要调整下，根据使用的theme不同，宽度需要调整

2、自定义DateTime Field输入控件。
/**
* 带时间的日期输入控件
* 转载请注明来自于gogo1217.iteye.com
*/
Ext.define('Go.form.field.DateTime', {
extend:'Ext.form.field.Date',
alias: 'widget.datetimefield',
requires: ['Go.picker.DateTime'],
/**
* @cfg {String} format
* The default date format string which can be overriden for localization support. The format must be valid
* according to {@link Ext.Date#parse}.
*/
format : "Y-m-d H:i:s",
/**
* @cfg {String} altFormats
* Multiple date formats separated by "|" to try when parsing a user input value and it does not match the defined
* format.
*/
altFormats : "Y-m-d H:i:s",
createPicker: function() {
var me = this,
format = Ext.String.format;
//修改picker为自定义picker
return new Go.picker.DateTime({
pickerField: me,
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();
}
}
});
},
/**
* @private
*/
onExpand: function() {
var value = this.getValue();
//多传一个参数，从而避免时分秒被忽略。
this.picker.setValue(Ext.isDate(value) ? value : new Date(), true);
}
});
?3、测试示例代码：
<html>
<head>
<title>Ext JS 4.2 Examples</title>
<meta http-equiv="Context-Type" content="text/html;chartset=utf-8">
<link rel="stylesheet" type="text/css" href="resources/ext-theme-neptune/ext-theme-neptune-all.css" />
<script type="text/javascript" src="ext-all.js"></script>
<script type="text/javascript" src="locale/ext-lang-zh_CN.js"></script>
<script type="text/javascript">
//启动ExtJs4动态加载特性
Ext.Loader.setConfig({
enable:true,
disableCaching:false,
path:{
'Go':'Go/'
}
});
Ext.onReady(function(){
Ext.create('Go.form.field.DateTime',{
renderTo:Ext.getBody(),
fieldLabel:'日期选择器',
value:'2013-04-27 12:12:12',
format:'Y-m-d H:i:s'
});
});
</script>
