Fb:js-string
From Facebook Developers Wiki
[edit] Description
This tag renders a block of FBML into an FBML block variable instead of rendering it on the page. You can use this variable in your JavaScript with setInnerFBML. See FBJS for more information.

[edit] Examples
| <fb:js-string var="example">Pre-rendered FBML content.</fb:js-string> a screenshot is not applicable for this tag |
| <fb:js-string var="name.element1">This is the first element.</fb:js-string>
<fb:js-string var="name.element2">This is the second element.</fb:js-string>
This allows you to access name as if it were a JavaScript array. The array can only be one level deep, and associative names must be prefixed by at least 1 alphabetical character (name.5, name.6, etc. will not work). Real example (PHP): <fb:js-string var="articles.id{$article['article_id']}"> Do you really want to delete article #{$article['article_id']}?<br /><br /> Associated contributors to this article will remain credited. </fb:js-string> <a href="#" onclick="removeArticle({$article['article_id']})">Delete Article</a><span id="removeSpan{$article['article_id']}"></span> <script> function removeArticle(articleId) { var dialog = new Dialog(Dialog.DIALOG_CONTEXTUAL); dialog.setContext(document.getElementById("removeSpan"+articleId)); dialog.showChoice('Confirm Removal', articles["id"+articleId], 'Yes', 'Cancel'); dialog.onconfirm = function() { document.setLocation('http://apps.facebook.com/facebookdocs/removearticle.php?article='+articleId); }; } </script> Another Example - Reloading an IFrame Let's say you have a div with an IFrame in it that you want to load different locations depending on links a user clicks. <a onClick="outside_location.setInnerFBML(location_two);" style="cursor: pointer;">Other IFrame Location</a> <div id="outside_location"> <fb:iframe width="540" height="270" frameborder="0" src="http://your.default.location" /> </div> // To reload the iFrame with a different location source you will need // to declare the location inside of a fb:js-string object like so: <fb:js-string var="location_two"> <fb:iframe width="540" height="270" frameborder='0' src='http://your.other.iframe.location' /> </fb:js-string> <script type="text/javascript" charset="utf-8"> var outside_location = document.getElementById('outside_location'); </script> |
