We are using jQuery thickbox to dynamically display an iframe when someone clicks on a picture. In this iframe, we are using galleria a javascript library to display multip
Basically what others have already posted but IMHO a bit cleaner:
$('<iframe/>', {
src: 'https://example.com/',
load: function() {
alert("loaded")
}
}).appendTo('body');
I'm loading the PDF with jQuery ajax into browser cache. Then I create embedded element with data already in browser cache. I guess it will work with iframe too.
var url = "http://example.com/my.pdf";
// show spinner
$.mobile.showPageLoadingMsg('b', note, false);
$.ajax({
url: url,
cache: true,
mimeType: 'application/pdf',
success: function () {
// display cached data
$(scroller).append('<embed type="application/pdf" src="' + url + '" />');
// hide spinner
$.mobile.hidePageLoadingMsg();
}
});
You have to set your http headers correctly as well.
HttpContext.Response.Expires = 1;
HttpContext.Response.Cache.SetNoServerCaching();
HttpContext.Response.Cache.SetAllowResponseInBrowserHistory(false);
HttpContext.Response.CacheControl = "Private";
Found the solution to the problem.
When you click on a thickbox link that open a iframe, it insert an iframe with an id of TB_iframeContent.
Instead of relying on the $(document).ready
event in the iframe code, I just have to bind to the load event of the iframe in the parent document:
$('#TB_iframeContent', top.document).load(ApplyGalleria);
This code is in the iframe but binds to an event of a control in the parent document. It works in FireFox and IE.
In IFrames I usually solve this problem by putting a small script to the very end of the block:
<body>
The content of your IFrame
<script type="text/javascript">
//<![CDATA[
fireOnReadyEvent();
parent.IFrameLoaded();
//]]>
</script>
</body>
This work most of the time for me. Sometimes the simplest and most naive solution is the most appropriate.
Try this,
<iframe id="testframe" src="about:blank" onload="if (testframe.location.href != 'about:blank') testframe_loaded()"></iframe>
All you need to do then is create the JavaScript function testframe_loaded().
Following DrJokepu's and David Murdoch idea I implemented a more complete version. It requires jQuery on both the parent and iframe and the iframe to be in your control.
iframe code:
var iframe = window.frameElement;
if (iframe){
iframe.contentDocument = document;//normalization: some browsers don't set the contentDocument, only the contentWindow
var parent = window.parent;
$(parent.document).ready(function(){//wait for parent to make sure it has jQuery ready
var parent$ = parent.jQuery;
parent$(iframe).trigger("iframeloading");
$(function(){
parent$(iframe).trigger("iframeready");
});
$(window).load(function(){//kind of unnecessary, but here for completion
parent$(iframe).trigger("iframeloaded");
});
$(window).unload(function(e){//not possible to prevent default
parent$(iframe).trigger("iframeunloaded");
});
$(window).on("beforeunload",function(){
parent$(iframe).trigger("iframebeforeunload");
});
});
}
parent test code:
$(function(){
$("iframe").on("iframeloading iframeready iframeloaded iframebeforeunload iframeunloaded", function(e){
console.log(e.type);
});
});
