<script>
function getLocalTime(addNum){//参数为加几天
var today,ms,thatDay, y, m, d,endDate;
today = new Date().getTime();
ms = today + addNum*24*60*60*1000;
thatDay = new Date(ms);
y = thatDay.getFullYear();
m = thatDay.getMonth()+1;
d = thatDay.getDate();
endDate = y+"-"+m+"-"+d;
alert(endDate);
//return endDate;
}
</script>
</head>
<body>
<input type='text' id='a' onclick="getLocalTime('1')"/>
</body>
<html>方法2:
<html>
<head>
<script>
function getLocalTime(addNum){//参数为加几天
var d2=document.getElementById("aa").value;
var arys= new Array();
arys=d2.split('-');
//得到日期类型
var myDate = new Date(arys[0],arys[1],arys[2]);
myDate=myDate.valueOf();
myDate=myDate +addNum * 24 * 60 * 60 * 1000;
myDate = new Date(myDate);
alert(myDate.getFullYear() + "-" + (myDate.getMonth()) + "-" + myDate.getDate() );
}
</script>
</head>
<body>
<input type='text' id='aa' value='2017-7-5' onclick="getLocalTime('1')"/>
