AJAX 调用有问题。我认为这个大而时髦的函数本质上会返回一个是/现在的字符串。
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');
}
});
这是简单的版本,我已将问题深入到此功能。这是我不断收到的错误:
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.
查询尝试访问的 URL 有效。如果我只是把它放到浏览器中,我会得到一些 XML。但是当我尝试使用 AJAX 时,我得到了这个错误。
