Question

I am trying to get Json format data from this website .. http://www.livetraffic.sg/feeds/json

however when i use ajax.. i run into this particular error in my chrome console.

Error:XMLHttpRequest cannot load. Origin null is not allowed by Access-Control-Allow-Origin.

Is the external website preventing my from using information?

Thanks for your help!!!

Sample of my code:

url = "http://www.livetraffic.sg/home2/get_erp_gantry";   
$().ready(function(){ 
        $.get(resturl, function(data) {
        //do something here with data
 });
});

This is your browser enforcing the same-origin policy. You are not allowed to make requests to domains other than the domain your script was fetched from.

You will have to set up some server-side proxy on the same domain as the one your script is served from and have it supply the data. (You could also cache this data on the server if it would make sense.)
