前言:
眼前朋友们对“js字符串日期”大致比较看重,看官们都需要剖析一些“js字符串日期”的相关知识。那么小编同时在网摘上网罗了一些对于“js字符串日期””的相关文章,希望各位老铁们能喜欢,兄弟们快快来了解一下吧!js需要把时间戳转为为普通格式,一般的情况下可能用不到的,但是我在做计时钟时php给的是 时间戳这样我们可以方便计划时分秒。
下面先来看第一种吧
代码如下复制代码
<script>
function getLocalTime(nS) {
return new Date(parseInt(nS) * 1000).toLocaleString().replace(/:d{1,2}$/,' ');
}
alert(getLocalTime(1293072805));
</script>
结果是
2010年12月23日 10:53
第二种
代码如下复制代码
<script>
function getLocalTime(nS) {
return new Date(parseInt(nS) * 1000).toLocaleString().substr(0,17)}
alert(getLocalTime(1293072805));
</script>
如果你想得到这样格式的怎么办呢?
2010-10-20 10:00:00
看下面代码吧
代码如下复制代码
<script>
function getLocalTime(nS) {
return new Date(parseInt(nS) * 1000).toLocaleString().replace(/年|月/g, "-").replace(/日/g, " ");
}
alert(getLocalTime(1177824835));
</script>
也可以这样写的
代码如下复制代码
function formatDate(now) {
var year=now.getYear();
var month=now.getMonth()+1;
var date=now.getDate();
var hour=now.getHours();
var minute=now.getMinutes();
var second=now.getSeconds();
return year+"-"+month+"-"+date+" "+hour+":"+minute+":"+second;
}
var d=new Date(1230999938);
alert(formatDate(d)); 好了问题解决
需要注意的是
不要把字符串中的Date(这样的字符也传进去,要先处理一下,这样很方便 就能处理的
可以使用replace方法
如下:
代码如下复制代码replace("/Date(","").replace(")/","");
完整实例
代码如下复制代码/**
* 和PHP一样的时间戳格式化函数
* @param {string} format 格式
* @param {int} timestamp 要格式化的时间 默认为当前时间
* @return {string} 格式化的时间字符串
*/
function date(format, timestamp){
var a, jsdate=((timestamp) ? new Date(timestamp*1000) : new Date());

if((n = n + "").length < c){
return new Array(++c - n.length).join("0") + n;
} else {
return n;

ret = s;
} else if( f[s] ){
// a date function exists

}
return ret;
});
}
调用方法 能够很方便的将时间戳转换成日期的格式,如:
代码如下复制代码date('Y-m-d','1350052653');//很方便的将时间戳转换成了2012-10-11
date('Y-m-d H:i:s','1350052653');//得到的结果是2012-10-12 22:37:33
