我如何只允许从日期选择器中选择从今天起最多一年的时间？

Question

Right now I have my calendar working and set up so that paste dates are disabled according from today's date. How can I also disable dates after 365 days from the current date?

fiddle: https://jsfiddle.net/ts8acmow/1/

var today = new Date();
var dd = today.getDate();
var mm = today.getMonth() + 1;
var yyyy = today.getFullYear();
 if(dd<10){
        dd='0'+dd
    } 
    if(mm<10){
        mm='0'+mm
    } 

today = yyyy+'-'+mm+'-'+dd;
document.getElementById("start").setAttribute("min", today);

It is really the same principle, but for the max attribute.

Here is how you could do it:

 function fmt(dt) { return dt.toLocaleDateString("se"); // shortcut: Sweden locale has YYYY-MM-DD format } var today365 = new Date(); today365.setDate(today365.getDate()+365); var start = document.getElementById("start"); start.setAttribute("min", fmt(new Date())); start.setAttribute("max", fmt(today365)); 

 <input type="date" id="start">
