我试过这样的

<script type="text/javascript">
     var date2=02/09/2009;
     var date1=03/12/2009;
     var diff = date1.getDate()-date2.getDate();
     alert (diff);

</script>

但它不起作用,这个理由getDate只会起作用Date吗？

如何找到这两个日期之间的差异？我无法使用此功能,因为我在salesforce CRM apex页面中添加了javascript？

编辑1:事实上这也不起作用

<script type="text/javascript">
     var date2= new Date ("02/09/2009");
     var date1= new Date ("04/09/2009");
     var diff = date1.getDate()-date2.getDate();
     alert (diff);

</script>

编辑2:它不能正常工作......

<script type="text/javascript">
     var date2= "02/09/2009";
     var date1= "04/09/2009";
     var diff2 =    new Date(Date.parse("03/12/2009")-
                        Date.parse("02/09/2009")).toLocaleDateString();

// var new_date = new Date(1970,01,01); // var diff3 = diff2.getDate(); alert(diff2);

</script>
