Redirect based on screen resolution with jQuery?

You don't need jQuery.

You can use screen.width, which works in all browsers:

if (screen.width <= 1024) window.location.replace("http://www.example.com/1024.html")
else window.location.replace("http://www.example.com/index.html")

See http://www.dynamicdrive.com/dynamicindex9/info3.htm

 if ($(window).width() <= 1024) location.href = "1024.html";

docs on width()

$(document).ready(function() {
    if (screen.width >= 1024) {
        window.location.replace("http://example.com/1024.html");
    }
    else  {
        window.location.replace("http://example.com/index.html");
    }
});

Reference notes in the answer to this question on difference between window.location.replace and window.location.href.
