Trying to use jQuery to trigger an anchor click after the page loads

So this has been asked a number of times on here, and while I've read all of the threads I can find, this still isn't working for me.
A little background: I'm working on a Wordpress site with a grid plugin, and I'm trying to trigger a filter when the page loads, depending on a url parameter. For the purpose of this thread I've just hardcoded a url parameter (the category variable) as an example because that functionality is working fine.
The anchor tag I'm trying to trigger:
Tarps and Covers
The broken code I'm trying to use to trigger the click event:
<script type="text/javascript">
$(document).ready(function() {
var hash = window.location.hash;
var category = '55';
var anchor = $("[data-category=" + category + "]");
anchor.click();
});
</script>
A console log returning the anchor variable confirms that I'm selecting the correct jQuery object, and I've also tried anchor[0].click() to trigger it with no success. Does anyone see any problems that I'm overlooking?

I tried it :
$(document).ready(function() {
var hash = window.location.hash;
var category = '55';
var anchor = $("[data-category=" + category + "]");
anchor.click();
anchor.on('click',()=>{
alert();
})
});
Everything is working

Youtube Iframe jQuery code fails on ajax website

My webpage is full ajax navigation, when clicking through various links in the page and I have jQuery code being used on the page but it fails to load when clicking ajax links. I have tried using on. live. delegated. but they all did not work.
I used the below code I found on here to reload my jquery code
//function initialise(){
$('.youtube iframe').each( function(){
// return if we're dealing with google ads iframe
if ( typeof $(this).attr('src') == 'undefined' ) return;
var $this_video = $(this),
src_attr = $this_video.attr('src'),
wmode_character = src_attr.indexOf( '?' ) == -1 ? '?' : '&',
this_src = src_attr + wmode_character + 'wmode=opaque&rel=0&showinfo=0&modestbranding=1&theme=light';
$this_video.attr('src',this_src);
} );
};
// $(document).ready(function(){
initialise();
});
// $(document).ajaxComplete(function () {
initialise();
});
But when I use this code the iframe on the page seems stucked in a loop.I assume it's stuck in the loop because the ajax call checks for an update every few seconds but I want to know how I can apply my jQuery iframe code and not have it reloaded every few seconds

Running a check on content loaded in via a .load() function

had this niggling issue that i cant seem to figure out.
I have a blog post on a CMS that i am building and there is some content saved into a div with it own unique ID. When the user clicks an edit button, a CKeditor is shown (containing the same text as the div). I also display a save button which when clicked, calls the processing PHP script via AJAX.
On a database update success, i use this in my AJAX call:
if (response.databaseSuccess) {
$("#container #" +response.postid).load("#container #" +response.postContentID);
}
This works perfectly and loads the updated content into the div.
Now the issue...
On page load i use this:
$(document).ready(function () {
// check each image in the .blogtest divs for their width. If its less than X make it full size, if not its poor and keep it normal
function resize() {
var box = $(".blogtest");
box.find("img.buildimage").on('load', function () {
var img = $(this),
width = img.width();
if (width >= 650) {
img.addClass("buildimage-large");
} else if (width < 500 && width > 101) {
img.addClass("buildimage-small");
}
// if image is less than X, its most likely a smiley
else if (width < 100) {
img.addClass("buildimage-smiley");
}
}).filter(function () {
//if the image is already loaded manually trigger the event
return this.complete;
}).trigger('load');
}
resize();
});
This works, and checks the images for their width and acts accordingly. After the page has fully loaded the images correctly get given their new class which changes their width.
The problem is that i cannot get this function to work on the data that is saved. So when i click save and the content is loaded via .load(), the new images are not checked.
I have tried adding the above function into the AJAX success return but it doesnt do anything.
Any ideas?

If you are trying to hook into the onload event for images that have already been added to the page, it is very easy to miss the onload event, particularly if the image is already in the browser cache (and thus will load quickly) as the onload event may have already fired before you get a chance to attach your event handler. The usual work-around is to do something like this where you check to see if it's already loaded before attaching an onload handler:
box.find("img.buildimage").each(function() {
if (this.complete) {
// image already loaded so just process it here
} else {
// image not yet loaded so attach an onload handler
$(this).on("load", function() {
// now the image is loaded so process it here
});
}
});
I'm not sure exactly what code you're using to dynamically load new content. If you're doing that with Ajax, you need to make sure you don't fire the above code until after the content has been added to the page (the success or completion handler of whatever load operation you're using).
So, if this is where you're loading new content:
if (response.databaseSuccess) {
$("#container #" +response.postid).load("#container #" +response.postContentID);
}
then, you would use a completion handler callback on the .load() function to trigger the above code:
if (response.databaseSuccess) {
$("#container #" +response.postid).load("#container #" +response.postContentID, function() {
// code here that looks at the dynamically loaded content
});
}

Using ajax javascript to load content into a div in web page

I am having a little problem using javascript-ajax here. In my page, I load in the content into one of the div with id content in an ajax manner, whenever the user clicks on links which have the class myajaxreq, and the contents are loaded into the div in a fade in manner. The javascript that I am using is this
$(document).ready(function(){
$("#content").load($('.myajaxreq:first').attr('href'));
});
$('.myajaxreq').click(function() {
var myhref=$(this).attr('href');
$('#content').hide().load(myhref).fadeIn('slow');
return false;
});
All works great on localhost, but when i put it online and then when we click on these links, then: First the same content which was initially there in the div is loaded in fade in manner. After a few seconds, the new content is loaded.
I think I am missing some sort of
if(content document is ready)
then load in a fade in manner
and so on..
Please somebody help me out here !!

call fade in after success callback... try this
var jContent = $('#content').hide();
jContent.load(
myhref,
{},
function(){
jContent.fadeIn('slow');
}
);
here the whole code (untested)
$(document).ready(function(){
var jContent = $("#content").load($('.myajaxreq:first').attr('href'));
$('.myajaxreq').click(function() {
var myhref=$(this).attr('href');
jContent
.hide()
.load(
myhref,
{},
function(){
jContent.fadeIn('slow');
}
);
return false;
});
});

Load javascript in html within content pane

I have an html file that I want to be loaded from various pages into a dijit.contentpane. The content loads fine (I just set the href of the contentpane), but the problem is that javascript within the html file specified by href doesn't seem to be executed at a consistent time.
The final goal of this is to load an html file into a contentpane at an anchor point in the file (i.e. if you typed in index.html#tag in order to jump to a certain part of the file). I've tried a few different methods and can't seem to get anything to work.
What I've tried:
1.
(refering to the href of the dijit.contentpane)
href="page.htm#anchor"
2.
(again, refering to the href of the dijit.contentpane -- didn't really expect this to work, but decided to try anyways)
href="#anchor"
3. (with this last try inside the html specified by href)
<script type="text/javascript">
setTimeout("go_to_anchor();", 2000);
function go_to_anchor()
{
location.href = "#anchor";
}
</script>
This last try was the closest to working of all of them. After 2 seconds (I put the delay there to see if something in the dijit code was possibly loading at the same time as my javascript), I could see the browser briefly jump to the correct place in the html page, but then immediately go back to the top of the page.

Dojo uses hashes in the URL to allow bookmarking of pages loaded through ajax calls.
This is done through the dojo.hash api.
So... I think the best thing you can do is use it to trigger a callback that you write inside your main page.
For scrolling to a given position in your loaded contents, you can then use node.scrollIntoView().
For example, say you have a page with a ContentPane named "mainPane" in which you load an html fragment called "fragment.html", and your fragment contains 2 anchors like this :
-fragment.html :
Anchor 1
<p>some very long contents...</p>
Anchor 2
<p>some very long contents...</p>
Now say you have 2 buttons in the main page (named btn1 and btn2), which will be used to load your fragment and navigate to the proper anchor. You can then wire that up with the following javascript, in your main page :
<script type="text/javascript">
require(['dojo/on',
'dojo/hash',
'dojo/_base/connect',
'dijit/layout/BorderContainer',
'dijit/layout/ContentPane',
'dijit/form/Button'],
function(on, hash, connect){
dojo.ready(function(){
var contentPane = dijit.byId('mainPane');
var btn1 = dijit.byId('btn1');
var btn2 = dijit.byId('btn2');
btn1.on("Click", function(e){
if (!(contentPane.get('href') == 'fragment.html')) {
contentPane.set("href", "fragment.html");
}
hash("anchor1");
});
btn2.on("Click", function(e){
if (!(contentPane.get('href') == 'fragment.html')) {
contentPane.set("href", "fragment.html");
}
hash("anchor2");
});
// In case we have a hash in the URL on the first page load, load the fragment so we can navigate to the anchor.
hash() && contentPane.set("href", "fragment.html");
// This callback is what will perform the actual scroll to the anchor
var callback = function(){
var anchor = Array.pop(dojo.query('a[href="#' + hash() + '"]'));
anchor && anchor.scrollIntoView();
};
contentPane.on("DownloadEnd", function(e){
console.debug("fragment loaded");
// Call the callback the first time the fragment loads then subscribe to hashchange topic
callback();
connect.subscribe("/dojo/hashchange", null, callback);
});
}); // dojo.ready
}); // require
</script>

If the content you're loading contains javascript you should use dojox.layout.ContentPane.
