I recently ran into a situation where I wanted to pull some content from another web site, however, due to a configuration constraint, I was unable to to this in a normal fashion.\u00a0 Essentially, there was a table of data (a subset of the content on the page) on another site which I wanted to include on my web page, but using an IFrame to display the content simply wasn\u2019t an option (due to the fact, I only wanted a subset of the data on the page).\u00a0 In fact, I wanted to pull the data and display it in a web part, embedded in a web part page in SharePoint.\u00a0 The main issue was that since I was doing this across domains (which is a big no-no for many security reasons), I had to come up with another technique.<\/p>\n

After searching around the web for a while and trying to come up with a decent technique, I fell upon this thread on stackoverflow.com http:\/\/stackoverflow.com\/questions\/3076414\/ways-to-circumvent-the-same-origin-policy<\/a>.\u00a0\u00a0 There\u2019s a number of noted techniques in there, but the one I chose was not one of the many highlighted earlier on in the thread, but instead a little one buried later on where someone discusses \u201canyorigin.com\u201d.\u00a0 Basically, ruling the items out one by one, iframe doesn\u2019t work, as I wanted sub-content.\u00a0 The AJAX discussion they\u2019re talking about sounded very browser specific, and also quite flaky, depending on the browser version.\u00a0 And window.postmessage wasn\u2019t an option as I didn\u2019t have direct access to the content on the other end, so I had no way of embedding anything that into the destination.<\/p>\n

How anyorigin.com<\/a> works is that you provide it a URL you\u2019re wanting to retrieve, and it will provide you back the content from that site, basically the entire web page, as a string in JavaScript (or jQuery if you want to call it that).\u00a0 You can then take that string and set it as the innerHTML value of a div (or other DOM node), and voila, you\u2019ve got the content from the other site.\u00a0 A little jQuery tweaking, and you\u2019ve got sub-content from that site.\u00a0 This was the complete solution for me \u2013 yay!\u00a0 So how did I do it?<\/p>\n

The Code<\/h2>\n

Disclaimer 1: Do not use this technique to take other\u2019s intellectual property or copyright material.\u00a0 This is only meant to be used on content you already own, or have permission to use.<\/em><\/p>\n

Disclaimer 2: The possibility of having a cross site scripting attack is very real by using this technique \u2013 below, I\u2019ve added a line which strips out any inline JavaScript \u201cscript\u201d tags for this very reason \u2013 I highly recommend you do not remove that security precaution.<\/em><\/p>\n

So what my solution looks like is below.\u00a0 Essentially, it\u2019s a block of code I embed into a SharePoint script editor web part (in 2013 \u2013 in 2010 use a content editor), and it runs itself when the page loads.<\/p>\n

Simply replace the yellow highlighted text<\/span> below with the website URL you\u2019re looking to query for data.\u00a0 And the purple text<\/span> below with the location of the content (see the comment).<\/p>\n

\/\/Start of code<\/span><\/p>\n

<script src=”<\/span>http:\/\/code.jquery.com\/jquery-1.9.1.min.js”<\/span><\/a>><\/script>
\n<script type=”text\/javascript”>
\n   var ExternalURL = “www.dummysite.com<\/span>“; \/\/ This address must not contain any leading “<\/span>http:\/\/”<\/span>
\n   var ContentLocationInDOM = “#someNode > .childNode<\/span>“; \/\/ If you’re trying to get sub-content from the page, specify the “CSS style” jQuery syntax here, otherwise set this to “null”<\/span><\/p>\n

   $(document).ready(loadContent);<\/span>
\n   function loadContent()<\/span>
\n   {<\/span>
\n      var QueryURL = “http:\/\/anyorigin.com\/get?url=”<\/span> + ExternalURL + “&callback=?”;
\n      $.getJSON(QueryURL, function(data){
\n         if (data && data != null && typeof data == “object” && data.contents && data.contents != null && typeof data.contents == “string”)
\n         {
\n            data = data.contents.replace(\/<script[^>]*>[sS]*?<\/script>\/gi, ”);
\n            if (data.length > 0)
\n            {
\n               if (ContentLocationInDOM && ContentLocationInDOM != null && ContentLocationInDOM != “null”)
\n               {
\n                  $(‘#queryResultContainer’).html($(ContentLocationInDOM, data));
\n               }
\n               else
\n               {
\n                  $(‘#queryResultContainer’).html(data);
\n               }
\n            }
\n         }
\n      });
\n   }
\n<\/script>
\n<div id=”queryResultContainer”\/><\/span><\/p>\n
