JavaScript实现日期字符串与毫秒数相互转换

<script>
function c1(){
var d = document.getElementsByName("s")[0].value;
var b = (new Date(d)).getTime();
document.getElementsByName("s")[0].value = b;
}
function c2(){
var d = document.getElementsByName("d")[0].value;
var b = new Date(d);
b.setTime(d);
document.getElementsByName("d")[0].value = b;
}
</script>
转毫秒<input name="s" value=""><input type="button" onclick="c1()"
value="ssss" > \n转日期<input name="d" value=""><input type="button"
onclick="c2()" value="dddd" >
