I have an API which works appending the fancybox script to the head tag of the client's web page, but obviously this happens after the dom is ready, so the init function of fancybox is not called
In fancybox.js:
$(document).ready(function() {
$.fancybox.init();
});
I've tried changing it to :
$(document).bind('ready', function() {
$.fancybox.init();
});
and then triggering the dom ready function in different ways (one by one):
$(document).trigger("ready");
$().trigger("ready")
$().ready();
I've also tried calling the init function when the script is loaded:
$.fancybox.init();
Nothing seems to work.
I'm sure that the fancybox.css, the fancybox.js and even mousewheel.js and easing.js are loaded in the documment before trying all that, I also added a timeout to be sure.
So the question is, how can the fancybox plugin be initialized after appending the js to the head tag?
I don't think you need to call $.fancybox.init(); but just initialize the proper selector after the fancybox script has been loaded so I would try within the API something like :
if (!jQuery.fn.fancybox){
// fancybox is not loaded
jQuery.getScript("{path}/jquery.fancybox.js"); // you may need to change the path
setTimeout(function(){
// init fancybox selector
jQuery(".selector").fancybox();
}, 100); // delay selector initialization
} else {
// fancybox script is ready so initialize (re-init) selector
jQuery(".selector").fancybox();
};

I have Jquery function that executes AJAX query to server.
How can I call this after load page in the specified url page? May I bind this to element HTML, I mean:
<div id="graph" onload="function()"></div>
jQuery handles the HTML file with a variable called document.
Document has two popular event states
load when the page has been loaded
ready when the page has been loaded and all other decorations to the HTML have been applied.
jQuery provides hooks for these states.
To run javascript code after each of the events listed above, you have to put the function within the appropriate event scope.
For loading, this would be…
$(document).load(function() {
// javascript code you want to execute
})
After the page has been ready, but not yet rendered, you can apply some other javascript code using
$(document).ready(function() {
// javascript code you want to execute
})
One way using jQuery:
$(document).ready( function() {
//do whatever you need, you can check if some element exists and then, call your function
if($("#graph").length > 0)
callfunction();
});
No jQuery, only vanilla js:
window.onload = function() {
if(document.getElementById("graph"))
callfunction();
}
I have a javascript function, "loadFramework()" that modifies an HTML document. Specifically, it repeatedly runs the jQuery command $("#element-id").load("document/name.html"), which injects the HTML in document/name.html directly into the element with #element-id.
Originally, I ran loadFramework() in a script in the document's header. However, since then I've realized that the function fails if the page has not loaded yet, since it relies on there being an element with #element-id.
I can't figure out how to get this function to run when it should. A simple solution seemed to be setting it to be the document.onload function:
document.onload = function() {
loadFramework();
}
But in this case it never seems to run at all.
How do I make sure a header function runs only after the document has loaded?
You should use window.onload if you are looking for a vanilla JS option
window.onload = function() {
loadFramework();
}
Jquery load takes additional argument "complete". You can run the javascript there. So the code would be:
$("#element-id").load("document/name.html", function(){
loadFramework();
});
You can also use $(document).ready(function{loadFramework()}) inside the html you are loading.
If you want to execute the loadFramework() method after "document/name.html" is loaded, I would suggest the following code.
$(function() {
$("#element-id").load("document/name.html", function(){
loadFramework();
});
});
I have an iframe that represents the content of my main page and it loads a different src depending on the menu option chosen. I want to perform a series of actions as soon as the iFrame is loaded but I cant seem to get it to work. The code looks more or less like the following:
$(document).ready(function () {
$('#navigation').load(function () {
alert('frame loaded!')
});
});
.load for event binding was deprecated in jQuery 1.8, use .on("load" instead.
I asume this function is in your iFrame and will be executed after the document loading. If not - ther is some conceptual error. Anyway - the load function in jQuery will try to load a html document or piece of it in the object you specify - http://api.jquery.com/load/
I am trying to dynamically load fancybox via getScript and then attach it to a element. I have the fancybox dynamically load inside of a document ready...
So it goes.
documents ready -> getScript
But it doesn't seem to want to attach to my a tag (.fancybox) if I do a console.log jQuery('.fancybox') I get a [] but the element is already loaded? And if I type in jQuery('.fancybox').fancybox(); in the console in Google Chrome it still doesn't work?
Any idea what I am doing wrong?
jQuery.getScript("/fancybox/jquery.fancybox.pack.js", function() {
console.log(jQuery(".fancybox"),jQuery("a"));
return jQuery(".fancybox").fancybox();
});
The element is a simple a tag wrapping an image, and it is NOT dynamically loaded.
<div class="youtube"><img height="181" src="images/youtube-video.png" width="326"></div>
document ready is too early try wrapping it in $(window).load(function(){//CODE HERE}); instead because it needs to run only after DOM has loaded so it can apply your fancybox to your DOM element.
Try this:
jQuery.getScript("/fancybox/jquery.fancybox.pack.js", function() {
jQuery(document).ready(function() {
jQuery(".fancybox").fancybox();
});
});
EDIT: function call fixed
I wanted to load some fragments of external content inside a div, through a menu.
Found "load" and "live", found a tutorial used it = success!
Except, like what's explicit in the documentation, it doesn't load JavaScript.
The thing is, the destination page already loads, inside the header, that same JavaScript, 'cause Wordpress loads it in every page. In this particular page, I'm only using the plugin (nextgen gallery) through the jQuery AJAX call.
So, what I believe is my problem is that I somehow need to alert/reload the JavaScript, right?
And how can I do this?
<script type="text/javascript" charset="utf-8">
jQuery(document).ready(function(){
// ajax pagination
jQuery('#naveg a').live('click', function(){ // if not using wp-page-numbers, change this to correct ID
var link = jQuery(this).attr('href');
// #main is the ID of the outer div wrapping your posts
jQuery('#fora').html('<div class="loading"><h2>Loading...</h2></div>');
// #entries is the ID of the inner div wrapping your posts
jQuery('#fora').load(link+' #dentro')
return false;
});
}); // end ready function
</script>
PS: I've substituted "live" with "on" but didn't work either.
I'm not sure if I understand... your load() command is puling in some Javascript that you want executed? I'm not sure if you can do that. But if you just need to call some JS upon load() completion, you can pass it a function like so:
jQuery('#fora').load(link+' #dentro', function() {
console.log("load completed");
// JS code to be executed...
});
If you want to execute Javascript code included in the loaded page (the page you retrieve via .load()), than you have to use the url-parameter without the "suffixed selector expression". See jQuery documentation for (.load()):
Note: When calling .load() using a URL without a suffixed selector expression, the content is passed to .html() prior to scripts being
removed. This executes the script blocks before they are discarded. If
.load() is however called with a selector expression appended to the
URL, the scripts are stripped out prior to the DOM being updated,
which is why they are never executed. An example of both cases can be
seen below:
Here, any JavaScript loaded into #a as a part of the document will
successfully execute.
$('#a').load('article.html');
However in this case, script blocks in the document being loaded into
#b are stripped out prior to being executed:
$('#b').load('article.html #target');
I think that's your problem (although I have no solution for you, sorry).
Proposal: Maybe you can load the whole page (including the Scripts) and remove (or hide) the parts you don't need?
Cheers.
