extjsdateformat

㈠ extjs日期格式化成java的yyyyMMddHHmmssSSS的形式,怎样写

Ext.util.Format.date(date,'YMdHmsu') 类似这样的试下
具体参考下api中Extjs中util.Format里面的方法和Date里面对时间单位的解释

㈡ Extjs 中DateFiled的日期格式问题

{
header:'时间',
dataIndex:'date',
editor:newExt.grid.GridEditor(newExt.form.DateField({
format:'Y-m-d'
})),
renderer:function(value){
returnvalue.format("Y-m-d");
}
}

㈢ extjs 如何禁用日期时间控件

1、extjs日期控件禁用：设置editable:false这个属性即可。
editable：是否可编辑，默认为true 。

2、Extjs日期控件禁止用户输入（设版置readOnly为true）：
JScript 代码权 ：
{
xtype:"datefield",
format:"Y-m-d",
value:"1986-12-25",
readOnly:true, //设置为true为只读状态，禁止用户输入
fieldLabel:"Birth"
}

3、extjs DateField 的值用getValue()方法获取后是一大堆字符串，类似Tue Dec 07 2010 00:00:00 GMT 0800，存入数据库需要格式化一下，用EXT的Ext.util.Format.date（）方法：
var gedt = Ext.util.Format.date(日期控件.getValue(), 'Y-m-d');
出来的日期格式就是 2010-10-10。

㈣ extjs GridPanel怎么添加ComboBox，TextField等form控件

就是用extjs键表格。。。用grid吧。。给你个例子

Ext.onReady(function(){

/**

*/

functionformatDate(value){

returnvalue?value.dateFormat('Md,Y'):'';

}

//shorthandalias

varfm=Ext.form;

//

//

varcm=newExt.grid.ColumnModel({

㈤ extjs获取当前时间并且怎么取7天前的时间

///获取当前日期(到秒)
var curDate = new Date()
//格式化;
var time=Ext.Date.format(curDate, 'Y-m-d');
///取7天前的时间
var now = new Date(new Date()-7*24*60*60*1000);
alert(now);
或
var today = new Date();
today.setDate(parseInt(today.getDate()) - 7);
console.log(today.toLocaleString());

㈥ Extjs4 Calendar例子如何把Memory类型的store改为Ajax的json形式如果有实例更好

你需要配置 dateFormat
StartDate: {
name: 'StartDate',
mapping: 'start',
type: 'date',
dateFormat: 'c'
},
比如 'F j, Y, g:i a' 对应 January 10, 2007, 3:05 pm

具体配置参见下表

㈦ Extjs的datefield怎么获取当前系统时间所属月月初到月末

varmyDate=newDate();
varyear=myDate.getFullYear();
varmonth=myDate.getMonth()+1;
if(month<10){
month="0"+month;
}
varfirstDay=year+"-"+month+"-01";
varmyDate=newDate(year,month,0);
varlastDay=year+"-"+month+"-"+myDate.getDate();
//然后复制即可
datefeildStart.setValue(firstDay);
datefeildEnd.setValue(lastDay);

㈧ Extjs 前台向后台传时间类型数据 数据格式发生变化怎么解决

假设你的处理是这样，使用store和model，用datetime控件
你需要在model里写，
name: fieldname, type: 'date', dateFormat: DefaultLongDateFormat,
这样才可以从后台接收正确的格式

在datetime中写
submitFormat ： DefaultLongDateFormat,//这个是提交的格式
format : DefaultShortDateFormat//这个是显示格式

var DefaultLongDateFormat = 'Y/n/j G:i:s';//长日期格式
var DefaultShortDateFormat = 'Y/n/j';//短日期格式

DefaultLongDateFormat你要根据你后台的情况修改

㈨ Extjs的DateField问题(急):在做修改功能时，如果数据库字段是Date类型时，页面不能获得原来的日期数据

你的extjs页面写的format了么？format:'Y-m-d'，在items:[{xtype:'datefield',format:'Y-m-d'}]这样就显示出来了，我也出过这样的问题
