js按时间命名文件

var date = new Date(); 
// var seperator1 = "/"; 
var year = date.getFullYear(); 
var month = date.getMonth() + 1; 
var strDate = date.getDate(); 
var hour = date.getHours()
if (month >= 1 && month <= 9) { 
    month = "0" + month; 
} 
if (strDate >= 0 && strDate <= 9) { 
    strDate = "0" + strDate; 
} 
var v2Currentdate = "关联与第三方发票_" + year.toString() + month.toString() + strDate.toString() + hour.toString() + ".xls"; 
v2Currentdate;
