How to insert today's date into a URL?
提问by PUSTAKAKORAN.COM
I have a url that change every day based on today's date, for example:
我有一个根据今天的日期每天都在变化的网址，例如：
http://www.newspaper.com/edition/20141227.html
where 20141227 is in the format YYYYMMDD.
其中 20141227 的格式为 YYYYMMDD。
Can I include the date using JavaScript? If possible, how would I do that?
我可以使用 JavaScript 包含日期吗？如果可能，我该怎么做？

Date.prototype.toMyString = function () {
//If month/day is single digit value add perfix as 0
function AddZero(obj) {
obj = obj + '';
if (obj.length == 1)
obj = "0" + obj
return obj;
}
var output = "";
output += this.getFullYear();
output += AddZero(this.getMonth()+1);
output += AddZero(this.getDate());
return output;
}
var d = new Date();
var link = document.getElementById("link");

Here's a simpler method that works
这是一个更简单的方法
<script>
var link = document.getElementById('link'); // ref. to your anchor tag
var d = new Date,
date = d.getDate(),
month = d.getMonth()+1, // Months in JavaScript are 0 indexed
year = d.getFullYear();
if(date < 10) date = ("0" + date);
if(month < 10) month = ("0" + month);
link.href = ("STATIC_URL/" + year + month + date);//Concatenating three numbers, kind of a hack
</script>
This is as simple as it gets.
这很简单。

var yyyy = today.getFullYear();

if(mm<10){mm='0'+mm};
today = yyyy+mm+dd;
var new_url=document.URL+"/"+today+".html";

var date = new Date().toDateString("yyyyMMdd");
then paste the date in building the URL
然后在构建 URL 时粘贴日期
url = "http://blahblahblaj.com/"+date
url = " http://blahblahblaj.com/"+日期
