JavaScript equivalent to printf/string.format

I am creating code like this:

var ds = "ds=" + encodeURIComponent($('#DataSource').val());
var ex = "ex=" + encodeURIComponent($('#EID').val());
var to = "to=" + encodeURIComponent($('#TID').val());
var st = "st=" + encodeURIComponent($('#SID').val());
window.location.href = '/person?' + ds + "&" + ex + "&" + to + "&" + st;

Is there some way in Javascript that I could use formatting to make the code look a bit cleaner? Also do I need to encode each element or can I just encode the variable abc?

There’s not a lot you can do, really. You could alias the encodeURIComponent method and use an array with join() if you’re looking for something a little neater:

var e = encodeURIComponent, 
    arr = [
        "ds=" + e($('#DataSource').val()),
        "ex=" + e($('#EID').val()),
        "to=" + e($('#TID').val()),
        "st=" + e($('#SID').val())
    ];

window.location.href = '/person?' + arr.join("&");
