Javascript implementiert Datumsformatkonvertierung_Javascript-Fähigkeiten

复制代码 代码如下:

<script><br> window.onload = function(){<br>     var aLaydate = document.getElementsByClassName("date");<br>     for(var i = 0;i < aLaydate.length;i )<br />     {<br />         aLaydate[i].onchange = function(){<br />             var dateValue = this.value;<br />             dateValue = dateValue.replace(/。/g,"-");<br />             dateValue = dateValue.replace(/./g,"-");<br />             if(dateValue.length == 8){<br />                 var temp = dateValue.substring(0,4) "-" dateValue.substring(4,6) "-" dateValue.substring(6,8);<br />                 dateValue = temp;<br />                 console.log(dateValue);<br />             }<br />             if(CheckDT(dateValue)){<br />                 this.value = dateValue;<br />             }<br />             sonst<br />             {<br />                 Alert("日期输入错误");<br />             }<br />         }<br />     }<br /> }<br />  <br /> Funktion CheckDT(str)    <br /> {    <br />     var r = str.match(/^(d{1,4})(-|/)(d{1,2})2(d{1,2})$/);    <br />     if(r==null)<br />     {<br />         return false;    <br />     }<br />     sonst<br />     {<br />         var d= neues Datum(r[1], r[3]-1, r[4]);    <br />         return (d.getFullYear()==r[1]&&(d.getMonth() 1)==r[3]&&d.getDate()==r[4]);<br />     }   <br /> }<br /> </script>

把输入的YYYY.MM.DD、YYYY.MM.DD、YYYYMMDD转为YYYY-MM-DD

CheckDT这个function是在度娘里找的.

很简单实用的功能吧，小伙伴们可以直接拿去使用.
