js实现日期选择器的两种方法（默认展示为最近一周）,第1张

方法一：

读取当前日期，再将day-7，判断day<=0针对不同月份的显示情况：

方法二：

先读取当前日期，再读取七天前日期。

显然，第二种方法简便了很多。

一下好一款laydate.js日期时间选择插件，具有一定的参考价值，希望可以帮到你

日期时间选择插件laydate.js：

效果图：

1. 引入JS。

2. 根据需要做相应的配置。详情参看官网

laydate({

elem: '#seldate', //目标元素。由于laydate.js封装了一个轻量级的选择器引擎，因此elem还允许你传入class、tag但必须按照这种方式 '#id .class'

event: 'focus', //响应事件。如果没有传入event，则按照默认的click

format: 'YYYY/MM/DD hh:mm:ss', // 分隔符可以任意定义，该例子表示只显示年月

festival: true, //显示节日

istime: true, //显示时间选项

choose: function(datas){ //选择日期完毕的回调

alert('得到：'+datas)

}

})

</script>
