I'm loading a custom page type that is just comments for a post. This is so I can use Disqus threads for easier usability when multiple loop posts are on a single page.
When loading an iFrame with the following structure I keep getting this syntax error. Are my escape characters wrong?
$(".boxyComments a").click(function (event) {
event.preventDefault();
var post_id = $(this).attr("rel");
$(".commentsIframeBig")
.get(0).contentWindow.location.href =
$("<?php echo get_site_url(); ?>","\/ajax-post-fold\/",post_id);
What's happening is the get retrieves the Wordpress hook to print the site url (in this case it prints http://whateverdomainex.com for the 1st call, 2nd should print /ajax-post-fold/ and the last call should print the post ID so the entire url ends up printing as http://whateverdomanex.com/ajax-post-fold/2825.
Instead my Chrome console gives me the following message:
Uncaught Error: Syntax error, unrecognized expression: /ajax-post-fold/
Update
I've put this variable into place and called it rather than the $("<?php echo get_site_url(); ?>","\/ajax-post-fold\/",post_id); as the get reference:
var postLink = $("<?php echo get_site_url(); ?>"+"\/ajax-post-fold\/"+post_id);
Implemented as such:
$(".boxyComments a").click(function (event) {
event.preventDefault();
var postLink = $("<?php echo get_site_url(); ?>"+"\/ajax-post-fold\/"+post_id);
var post_id = $(this).attr("rel");
$(".commentsIframeBig")
.get(0).contentWindow.location.href = postLink;
Which gives me the following Chrome message:
Uncaught Error: Syntax error, unrecognized expression: http://www.theciv.com/ajax-post-fold/28448
The URL that should be in the src attribute for the iFrame looks like it should be fine and good to go, so why is this syntax error still being output?
UPDATE
var postLink = "<?= site_url('\/ajax-post\/'); ?>"+post_id;
$(this).closest(".boxy").find(".commentsIframeBig")
.css("display","block")
.animate({height: "100%"}, 500)
.get(0).contentWindow.location.href = postLink;
With the proper structure above, the custom page is now loading in the iFrame. However the additional construct of +page_id which includes the rel attribute containing the post's id isn't loading properly.
Moreover when calling the new url as it's original custom page template, then adding the post's id does not load the correct page with post id. Confused yet? Read it again. Took me awhile to write that sentence.
In any case, now my mission to have the post id load when adding the custom page and the post_id as an added string for the iFrame's url to load properly.

Here is final working code to load Disqus comments into same page, pseudo multiple times.
Basically this is pushing a post id to the end of a custom page type, resulting in the post's content and attributable elements being loaded into the custom page template.
When stripping that custom page template down to just show the comments for the page, you can create a load/unload reaction whereby you are only calling Disqus once, removing that instance and then loading it again when another Load Comments button is clicked within a subsequently loaded post on the same page. Yay. Multiple Disqus commenting on one page with minimal Ajax loading.
Here is the structure et al that is almost working for me. Only 2 bugs left. First is the secondary load when emptying, then reloading the new Disqus page into the Ajax element using the .ajaxComplete() callback function.
What's happening now is the callback is basically not being fired at all. As far as I can tell. Clicking on it a second time however, does make the call. But this is due to the class parameters being met for the else statement.
Second bug left is I'm having a hard time figuring out how to get the appropriate elements to enlarge, while leaving the others the same size.
// Load comments and/or custom post content
$(".boxyComments a").click(function (event) {
event.preventDefault();
$.ajaxSetup({cache:false});
var post_id = $(this).attr("rel"); var excHeight = $(this).closest('.boxy').find('.initialPostLoad').height();
var postHeight = $(this).closest('.boxy').find('.articleImageThumb').height();
var postWidth = $(this).closest('.boxy').find('.articleImageThumb').width();
// close other comments boxes that may already be open
if($('.commentsOpen').length ) {
console.log('comments are open');
$('.bigBoxy').closest('.boxy')
.animate({height:(postHeight + excHeight)}, 500);
$('.showComments')
.removeClass('bigBoxy')
.removeClass('commentsOpen');
$('.commentsAjax')
.empty(function(){
$(this).closest(".boxy").find(".showComments")
.addClass("commentsOpen")
.addClass("bigBoxy");
$(".bigBoxy").find(".commentsAjax ")
.css("display","block")
.animate({height: "500px"}, 500)
.load("http://<?php echo $_SERVER[HTTP_HOST]; ?>/ajax-post/",{id:post_id});
$(this).closest(".boxy")
.ajaxComplete(function() {
var excHeight = $(this).closest('.boxy').find('.initialPostLoad')
.height();
var postHeight = $(this).closest('.boxy').find('.articleImageThumb')
.height();
$(this).closest(".boxy").animate({height: (postHeight + excHeight)}, 500)
});
});
} else {
$(this).closest(".boxyComments").find(".showComments")
.addClass("commentsOpen")
.addClass("bigBoxy");
$(this).closest(".boxy").find(".commentsAjax")
.css("display","block")
.animate({height: "500px"}, 500)
.load("http://<?php echo $_SERVER[HTTP_HOST]; ?>/ajax-post/",{id:post_id});
$(this).closest(".boxy")
.ajaxComplete(function() {
var excHeight = $(this).closest('.boxy').find('.initialPostLoad')
.height();
var postHeight = $(this).closest('.boxy').find('.articleImageThumb')
.height();
$(this).closest(".boxy").animate({height: (postHeight + excHeight)}, 500)
});
}
});
Okay, here's full working code to do what you want. You'll have to swap out a few placeholders for your actual code:
<script>
jQuery(document).ready(function($){$(".boxyComments a").click(function (event) {
event.preventDefault();
var post_id = $(this).attr("rel");
var postLink = "<?= site_url('/path/'); ?>"+post_id;
$("#myFrame").attr('src', postLink);
});
});
</script>
And sample divs & iFrame:
<div class='boxyComments'>
<a href='#' rel='some-url'>test link</a>
</div>
<div class=".commentsIframeBig">
<iframe id='myFrame' height="500px" width="800px" src=''>
</iframe>
</div>
Tested it locally and it worked no problem. You might have been running into issues with it not properly accessing the iFrame. If you can give the iFrame an id that makes it easier.
It's because you're declaring var postlink as a jQuery object. You just need to get it as a string that you can then pass to the iframe.
var post_id = $(this).attr("rel");
var postLink = "<?= site_url('/ajax-post-fold/'); ?>"+post_id;
UPDATE 2
Looks like the string shouldn't be included within the <?= get_site_url() ?> after all.
Instead I've created a few vars to affect it. Code updated below with answer:
var postDir = "\/ajax-post-fold\/";
var postLink = "<?= get_site_url(postDir); ?>"+"\/ajax-post-fold\/"+post_id;

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
I'm evaluating Featherlight lightbox and I'm not able to implement code that satisfies my use case. I need a lightbox that will be used as a report viewer which displays dynamically created content assigned to a JavaScript variable. The value of the string is a valid HMTL5 page.
I've looked at the iframe example, but it depends upon a static iframe being in the DOM. That's not what I need.
I've reviewed this GitHub issue and this jsfiddle and I'm not able to successfully modify the fiddle to display a string.
This is an example of the string I would like to display:
var s = '<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Title of the document</title></head><body><p>Content of the document......</p></body></html>';
Is this possible and if so how?
I expect that $.featherlight() will be called manually in response to a button click.
The solution I came up with was to modify the Featherlight source code in 2 places as indicated in this block of code (currently around line 383).
iframe: {
process: function(url) {
var deferred = new $.Deferred();
var $content = $('<iframe/>')
.hide()
.attr('src', url)
.attr('id', this.namespace + '-id') // [KT] 10/31/2016
.css(structure(this, 'iframe'))
.on('load', function() {if ($content.show()) {deferred.resolve($content.show()) } else {deferred.resolve($content)} ; }) // [KT] 10/31/2016
// We can't move an <iframe> and avoid reloading it,
// so let's put it in place ourselves right now:
.appendTo(this.$instance.find('.' + this.namespace + '-content'));
return deferred.promise();
}
},
The id attribute is added to the iframe so content can be added by JavaScript, like this:
var s = '<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Title of the document</title></head><body><p>Content of the document......</p></body></html>';
var oIframe = document.getElementById('featherlight-id'); // Featherlight's iframe
var iframeDoc = (oIframe.contentDocument || oIframe.contentWindow.document);
iframeDoc.open();
iframeDoc.write(s);
iframeDoc.close();
This then works:
$.featherlight({iframe: 'about:blank', iframeWidth: '96%' });
The 2nd modification is required so that the url 'about:blank' doesn't raise an error.
I also modified the css so as to get the scroll bars to work as needed.
Edit: the issue with Featherlight not opening an iframe when the url is abount:blank has been fixed as of version 1.5.1.
Edit 2: Using v1.5.1, this works without having to make a modification to Featherlight to add an id to to the iframe:
var s = '<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Title of the document</title></head><body><p>Content of the document......</p></body></html>';
$.featherlight({iframe: 'about:blank'});
var $iframe = $('.featherlight iframe');
$iframe.ready(function () {
$iframe.contents().find("body").append(s);
});

Hi I'm trying to load an element from a webpage via ID.
My code reads the url from the 'href' attribute of the tag and then loads the page. I'm stripping the document anchor.
This script works but won't discard the surround elements and loads the entire page.
<script type="text/javascript">
$(function() {
var a_href = $('#pycom').attr('href').split('#');
$('div#pop-up').load(a_href[0] + '#synopsis');
});
</script>
<body>
<a id="pycom" href="content/documentation/CommandsPython/ls.html#hFlags">ls</a>
</body>
http://help.autodesk.com/cloudhelp/2015/ENU/Maya-Tech-Docs/CommandsPython/ls.html
The above link exists locally on my server (XAMPP) as per the 'html' code above.
Below is the element I would like to extract.
<p id="synopsis">
<code>
xform([objects...],
[absolute=<i>boolean</i>],
[boundingBox=<i>boolean</i>],
.....
.....
</code>
Thanks
Jamie
At first get your page, and then inside the
content find your element with id named 'synopsis' as below:
var a_href = $('#pycom').attr('href').split('#');
$("div#pop-up").load(a_href[0] + " #synopsis" );
It should work, but before that check whether your browser supports mixed content. If your url contains http inside https then browser may not support, In that case you have to disallow the checking in the browser.
Thanks.
OK solved. I was using jQuery 2.4.1 which apparently has a bug that is supposed to be fixed.. but appears to be not?? see here http://bugs.jquery.com/ticket/14773
I am instead using jQuery 1.11.3
below is my final code:
<script type="text/javascript" src="content/scripts/jquery-1.11.3.js"></script>
<script type="text/javascript">
$(function() {
var moveLeft = -10;
var moveDown = 10;
$('a#pycom').hover(function(e) {
var a_href = $(this).attr('href').split('#');
$('#pop-up').load(a_href[0] + ' #synopsis');
$('div#pop-up').show().css('top', e.pageY + moveDown).css('left', ((e.width/100)*1) + moveLeft);
}, function() {
$('div#pop-up').hide();
});
});
</script>
The following method using .get also works exactly the same except gives the benefit of being able to process the returned string in the callback.. in this case the trailing section of the requested selected element... very nice stuff.
$('a#pycom').hover(function(e) {
var a_href = $(this).attr('href').split('#');
$.get(a_href[0], function(response) {
$('#pop-up').html($(response).filter('#synopsis').html().split('<br>')[0]);
});
});
Now owning jQuery like a BOSS!!
Thank you to all those who helped out.
Chur!

You should not give any space in the URL. There is a space before ' #synopsis'.
$('div#pop-up').load(a_href[0] + '#synopsis');
I am trying to send data to a index page when a link on that page is clicked. the index.php page looks like this:
include "../app/bootstrap.php";
include ("../src/controllers/DisplayContentsController.php");
$data = new DisplayContentsController();
$link = (isset($_POST['link']) ? $_POST['link'] : null);
if ($link != null)
{
$data->show($twig, $starting_file_path . '/' . $link);
$starting_file_path = $starting_file_path . '/' . $link;
}
else
{
$data->show($twig, $starting_file_path);
}
and on the Twig template that is loaded I have this:
<script>
jQuery('.show_content').click(function(e)
{
e.preventDefault();
var href = jQuery(this).attr('href');
jQuery.post(window.location, { link: href });
});
</script>
I want to reload the page with the new link that way it loads the correct directory. But when I do the jQuery.post() the content that is displayed does not change. Can someone help my find out what is going wrong and how I can accomplish this?
The output from the POST request would be returned on the success handler function. For example, you would need to do something like this:
jQuery('.show_content').click(function(e)
{
e.preventDefault();
var href = jQuery(this).attr('href');
jQuery.post(window.location, { link: href } , function(data){
//data will have the new HTML after the page posted back. You can use that
//HTML to load if onto an element on the page. Something like:
$('#content_result').html(data);
});
});
Assuming you have a div with "id = content_result" -or something like that- that you can use to load the HTML into it.
If you want to append the result to the existing HTML already displayed inside #content_result then simply do:
$('#content_result').html($('#content_result').html()+data);
Now, keep in mind that this will return everything - the full page - and if you blindly keep appending things, you'll end up with a page that does not conform to valid HTML -for example, a page with more than 1 <head>,<body> sections, etc. The best thing to do is to extract the section that you really care about, and append only that section such that you always end up with a valid HTML document.
jQuery offers plenty of options to do this sort of thing.
I am trying to add an external link to the Title in the images in colorbox, so that by clicking the title leads to an external page. Have added custom field in the posts( I am using Wordpress) and given key = 'url' and value = an external link, say http://facebook.com. Have around 10 images on my page.
I am calling the following in the jQuery ready function in my home.php, which further calls a loop.php to display the images in hp-thumb format. .
<script type="text/javascript">
jQuery(document).ready(function($) {
var keyValues = new Array();
keyValues = <?php echo get_post_custom_values('url');?>
var newLandingPage = keyValues[0];
$("a[rel='colorbox']").colorbox({title:function() {
return 'Go For This';
}
});
</script>
The problem is this is not displaying the Title at all. Where am I going wrong?
Thanks in Advance.
I got the solution. It was a small syntax mistake in php.
I needed to use:
var newLandingPage = keyValues['0'];
And I am done.
