Question

我尝试了很多不同的方法，但没有运气。我要做的就是确定当前URL的域，并从基于域的XML文件中提取一个值。

任何帮助都会非常感激。

merchants.xml

<?xml version="1.0" encoding="utf-8"?>
<catalog>
  <merchant id="1">
    <domain>http://www.amazon.com</domain>
    <affiliate>1</affiliate>
  </merchant>
</catalog>

popup.js

function ReadXML() {
    try {
        var xmlPath = "merchants.xml";
        $.ajax({
            type: "GET",
            url: xmlPath,
            dataType: "xml",
            success: parseXML
        });
    } catch (e) {
        alert("Error while reading XML; Description – " + e.description);
    }
}

function parseXML(xml) {
    var $merchant = $(xml).find('domain').filter(function() {
        return $(this).text() == "http://www.amazon.com";
    }).closest('domain');
    var affiliate = $('affiliate', $domain).text();

    if(window.location.hostname.indexOf("http://www.amazon.com") > -1) {
        document.getElementById("demo").innerHTML = affiliate;
    }
}

您可以使用jQuery XML to JSON Plugin将XML转换为JSON。因此，您将获得包含所有属性的Javascript对象：

{"merchant":{"domain":"http://www.amazon.com","affiliate":"1","id":"1"}}

完整样本：

<script type="text/javascript" src="https://code.jquery.com/jquery-2.2.3.min.js"></script>
<script type="text/javascript" src="https://jquery-xml2json-plugin.googlecode.com/svn/trunk/jquery.xml2json.js"></script>
<script type="text/javascript">
    $(function() {

        var 
            xml,
            json;

        xml = 

            '<?xml version="1.0" encoding="utf-8"?>' + 
            '<catalog>' + 
                '<merchant id="1">' + 
                '<domain>http://www.amazon.com</domain>' + 
                '<affiliate>1</affiliate>' + 
                '</merchant>' + 
            '</catalog>';

        json = $.xml2json(xml);

        alert(json.merchant.domain);
    });
</script>

var affiliateData = {};

function loadUrlData(url, data, affiliateData) {
  var urlDomain = url.substring(url.indexOf('//') + 2);
  if (urlDomain.indexOf('/') > -1) {
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('/'));
  }
  if (urlDomain.indexOf('?') > -1) {
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('?'));
  }

  lastIndexOfDot = urlDomain.lastIndexOf('.');
  if (lastIndexOfDot < 0) {
    return;
  }


  do {
    affiliateData[urlDomain] = data;
    urlDomain = urlDomain.slice(urlDomain.indexOf('.') + 1);
  } while (urlDomain.indexOf('.') > -1);
};
function getAffiliateData(url, affiliateData) {
  var urlDomain = url.substring(url.indexOf('//') + 2);
  if (urlDomain.indexOf('/') > -1) {
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('/'));
  }
  if (urlDomain.indexOf('?') > -1) {
    urlDomain = urlDomain.substring(0, urlDomain.indexOf('?'));
  }

  lastIndexOfDot = urlDomain.lastIndexOf('.');
  if (lastIndexOfDot < 0) {
    return 'none';
  }
  do {
    for (domain in affiliateData) {
      if (domain == urlDomain) {
        return affiliateData[domain];
      }
    }
    urlDomain = urlDomain.slice(urlDomain.indexOf('.') + 1);
  } while (urlDomain.indexOf('.') > -1);

  return 'none';
};

var url = 'http://www.amazon.com?asdf=/a/b/c';
var url2 = 'http://www.yahoo.com?asdf=/a/b/c';

loadUrlData('http://www.amazon.com?asdf=/a/b/c', 'data amazon', affiliateData);
loadUrlData('http://www.yahoo.com?asdf=/a/b/c', 'data yahoo', affiliateData);

alert(getAffiliateData(url, affiliateData));
alert(getAffiliateData(url2, affiliateData));
