# dateformat.js
> **dateformat.js** 是一个非常简洁、轻量级、不到 `5kb` 的很简洁的 Javascript 库，
它是一个时间的处理工具类。
- 支持常用的时间格式化
- 得到当前星期，时间对比大小，是否为闰年
- 增加日期，增加月份，增加年份等等
- 支持自动实时更新；
- 支持浏览器script方式；
- 测试用例完善，执行良好；
# 使用方法
**1. 引入 dateformat.js**
通过 `script` 标签引入到html文件中，会生成一个全局变量 `DateFormat`.
```js
<script src="dateformat.js"></script>
```
当然你还可以在通过 import 引入
```
import dateformat form '...自己的路径';
```
最后该项目也上传到npm上，你可以通过
```
//安装
npm install dateformat-util
```
```
//使用
var dateformat = require('dateformat-util');
dateformat.format(new Date());
```
**3. 使用 `dateformat` 类**
直接调用方法即可
```js
DateFormat.format(new Date(), 'yyyy-MM-dd hh:mm:ss');
```
# 具体方法
**1. format(date, fmt)**
`format` 是将 Date类型的时间进行格式化的工具方法：
```js
DateFormat.format(new Date()) //不传 fmt，则默认为 yyyy-MM-dd hh:mm:ss ;
DateFormat.format(new Date(), 'yyyy-MM-dd hh:mm:ss');
DateFormat.format(new Date(), 'yyyy/MM/dd hh:mm:ss');
DateFormat.format(new Date(), 'yyyy/MM/dd');
...
```
**2. formatToDate(dateStr)**
`formatToDate` 是将 字符串类型的时间 转化成 Date 类型的工具方法：
```
DateFormat.formatToDate('2017-04-18 12:12:12');
DateFormat.formatToDate('2017/04/18 12:12:12');
...
```
**3. getDateStart(date)**
`getDateStart` 是得到一天的开始，工作中会碰到这种需要得到某一天的开始或结束的时间点。
```js
DateFormat.getDateStart(new Date()); //今天是4.18, 那返回的是今天 00:00:00的Date类型
```
如果想返回字符串类型，可以使用 `getDateStartStr(date, fmt)` 方法，fmt非必传
```js
DateFormat.getDateStartStr(new Date(), 'yyyy-MM-dd hh:mm:ss'); //返回 2017-04-18 00:00:00
```
**4. getDateEnd(date)**
`getDateEnd` 是得到一天的结束
```js
DateFormat.getDateEnd(new Date()); //今天是4.18, 那返回的是今天 23:59:59的Date类型
```
如果想返回字符串类型，可以使用 `getDateEndStr(date, fmt)` 方法，fmt非必传
```js
DateFormat.getDateEndStr(new Date(), 'yyyy-MM-dd hh:mm:ss'); //返回 2017-04-18 23:59:59
```
**5. compareDate(d1, d2)**
`compareDate` 比较两个日期的大小
返回 1 , 则 d1 > d2
返回 0 , 则 d1 == d2
返回 -1, 则 d1 < d2
```js
DateFormat.compareDate(new Date(), new Date());
```
**6. getWeek(date, type)**
`getWeek` 得到一个日期是星期几
```js
DateFormat.getWeek(new Date()); //type非必传，默认返回 '星期 X'的格式
DateFormat.getWeek(new Date(), DateFormat.WEEKTYPE.US_DAYNAME); // Monday
/*
type 枚举如下：
DateFormat.WEEKTYPE.ZH_DAYNAME : 星期一
DateFormat.WEEKTYPE.ZH_SHORTDAYNAME: 周一
DateFormat.WEEKTYPE.US_DAYNAME： Monday
DateFormat.WEEKTYPE.US_SDAYNAME： Mon
*/
```
**7. addDay(date, num)**
增加系列：
```
addDay(date, num)
addDayStr(dateStr, num)
addMonth(date, num)
addMonthStr(dateStr, num)
addYear(date, num)
addYearStr(dateStr, num)
```
使用起来很简单，今天是 2017.04.18
```
DateFormat.addDay(new Date(), 3); //返回是三天后的 Date类型
DateFormat.addDayStr('2017-04-18 12:12:12', 3) // 返回 Fri Apr 21 2017 12:12:12 GMT+0800 (中国标准时间)
// 其他 month year的方式同上
```
