JavaScript如何将日期从字符串(YYYY-MM-DD)转换为长整型？

<script language="javascript">
aaa="1997-06-05"
arr=aaa.split("-")
str=arr.join("")
int=parseInt(str)
alert(int)
</script>
<script language="javascript">
aaa="1997-06-05"
int=Date.parse(aaa.replace(/-/g,"/"))
alert(int)
</script>
<script   language= "javascript ">
var aaa= "1997-06-05"
arr=aaa.split('-','')
int t=parseInt(str)
alert(t)
</script>
给你写个全的，带时间的<script>
var dateStr= "2010-06-03 12:12:12";
var date=dateStr.replace(/-/g,"").replace(/\s+/g,"").replace(/:/g,"");
var intDate=parseInt(date);
alert("转换后的结果"+intDate);
</script>
var birty = 你读取的日期；
var splitBirty = birty.split("-");
var str=splitBirty .join(" ");
var ints=parseInt(str);
ints.length;
