jsp页面通过js将时间格式化并赋初始值

<span style="font-size:18px;">//创建日期默认为当日 onload="javascript:initDate();"
function initDate(){
var date = new Date();
var seperator1 = "-";
var year = date.getFullYear();
var month = date.getMonth() + 1;
var strDate = date.getDate();
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (strDate >= 0 && strDate <= 9) {
strDate = "0" + strDate;
}
var currentdate = year + seperator1 + month + seperator1 + strDate;
$("#createDate").val(currentdate);
} </span>
