JQuery getJSON在IE中不起作用

I created a simple html in which I download data from MYSQL using php and jQuery. It works fine in Chrome(data refresh every 5 sec) but in IE even if the window.setInterval works fine the data downloads only once when the document is loaded for first time and after that the data is not refreshing.

function myFunc(){
    console.log("it works");
    $(document).ready(function(){
        $.getJSON("http://taxipolis.gr/phpfiles/drivers/get_alldrivers_coordinate_html.php",
            function (data) {
        });
    });
} 
window.setInterval(myFunc,5000);

What am I doing wrong?

I think you need to use XDomainRequest for ie. Try with this code

var xdr = new XDomainRequest();
xdr.onload = function() { alert("READY"); };
 xdr.open("GET", "http://taxipolis.gr/phpfiles/drivers/get_alldrivers_coordinate_html.php");
xdr.send();
