Having an issue with an AJAX call. I think this big, funky function that in essence gives back a yes/now for a string.

usdaurl = 'http://eligibility.sc.egov.usda.gov/eligibility/eligibilityservice?eligibilityType=Property&requestString=<?xml version="1.0"?><Eligibility xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="/var/lib/tomcat5/webapps/eligibility/Eligibilitywsdl.xsd"><PropertyRequest StreetAddress1="'+street+'" StreetAddress2="" StreetAddress3="" City="'+city+'" State="'+state+'" County="" Zip="'+zip+'" Program="RBS"></PropertyRequest></Eligibility>';
$.ajax({
    url: usdaurl,
    dataType: 'XML',
    success: function(xml){
        var usda = $('Property').attr('Eligibility');
    }
});

This is the simple version, I've drilled the problem down to this function. This is the error I keep getting: 

XMLHttpRequest cannot load http://eligibility.sc.egov.usda.gov/eligibility/eligibilityservice?eligibil…%2262034%22%20Program=%22RBS%22%3E%3C/PropertyRequest%3E%3C/Eligibility%3E. 
Origin http://[mydomain ;)] is not allowed by Access-Control-Allow-Origin.

The URL that the query is trying to access works. If I just put it in to a browser, I get back some XML. But when I try to use AJAX, I get this error.

  • Doing this via ajax is bad. Consider doing a 1px iframe. Opening the cross site scripting door can be a slippery slope of doom. – Joe Mills Mar 05 '13 at 05:51
  • So the source url of the 1px iframe is the URL of the AJAX call? How do you drill down into that iframe? Any reference links you could share? – Plummer Mar 05 '13 at 05:55

Ajax is not allowed to call other domains out of the box. There are some browser specific workarounds.
