Call user defined jQuery function with JS

I use a jQuery window libray https://github.com/humaan/Modaal
which triggers events this way $("class of element").modaal({arg1, arg2,...});
--- I updated my question here to make it more general and used an iframe / Html instead of an external svg ---
To trigger an element e.g. in an external Html which is loaded within an iframe, I applied the following code to the iframe:
<iframe src="External.html" id="mainContent" onload="access()"></iframe>
which calls this function:
function access() {
var html = document.getElementById("mainContent").contentDocument.getElementById("IDofDIVelement");
html.addEventListener('click', function() {clicker();});
}
function clicker()
{
// console.log('hooray!');
$("#mainContent").contents().find("IDofDIVelement").modaal({});
//return false;
}
Actually it will only work on every second click. Any idea what I did not consider properly?

You do not need to wait windows loading but iframe only:
$(function() {
$("#mainContent").bind("load",function(){
var myIframeElement = $(this).contents().find(".modaal");
myIframeElement.modaal({
content_source: '#iframe-content',
type: 'inline',
});
});
});

The reason why it did not work was that the iframe was not completely loaded, while jQuery tried to attach the function. As $(document).ready(function(){} did not work, the workaround was to initialize it with
$( window ).on( "load",function() {
$("#mainContent").contents().find("IDofDIVelement").modaal({});
});
This worked properly to attach the functionallity to an element within the iframe.
Actually modaal will vanish the envent handler after the overlay was opened and closed again.
So maybe someone wants to trigger an iframe element for modaal, too, here is a setup which would solve this issue.
(It can be optimised by #SvenLiivaks answer):
$(window).on("load", function() {
reload();
});
function reload() {
var length = $("#iframeID").contents().find("#IDofDIVelement").length;
// The following check will return 1, as the iframe exists.
if (length == 0) {
setTimeout(function() { reload() }, 500);
} else {
$("#iframeID").contents().find("#IDofDIVelement").modaal({
content_source: '#modalwrapper',
overlay_close: true,
after_close: function reattach() {
reload();
}
});
}
}

How to use jQuery to load codepress

I am using codepress in a CMS to edit files in the filesystem. Everything works nicely, however when trying to load the same page using jQuery load() function, codepress seems to break.
My javascript code looks like this which loads the php file with codpress, however codepress seems to not fire.
$('.content').on('click', '#fileSystemWrap a', function (event) {
event.preventDefault();
var fileName = $(this).data('file');
$('#rightColWrap').fadeOut(150, function(){
$('#rightColWrap').load('/?url=developer/edit-file.php&open=' + fileName, function(){
$('#rightColWrap').fadeIn(150);
});
});
});
Digging into codepress.js I see this at the end of the file but I'm not understanding if there is something I could add to my initial on click event listner script to help codpress fire.
if(window.attachEvent) window.attachEvent('onload',CodePress.run);
else window.addEventListener('DOMContentLoaded',CodePress.run,false);
Here is the link to codepress on sourceforge
https://sourceforge.net/projects/codepress/

To be logic : when the data are loaded, we want to initialize CodePress.
So your code should look like :
$('.content').on('click', '#fileSystemWrap a', function (event) {
event.preventDefault();
var fileName = $(this).data('file');
$('#rightColWrap').fadeOut(150, function(){
$('#rightColWrap').load('/?url=developer/edit-file.php&open=' + fileName, function(){
CodePress.run();
$('#rightColWrap').fadeIn(150);
});
});
});
If this didn't work please provide error from the console.
Edit : corrected answer, seen Robson França's comment.
Last issue was that CodePress.run; should have been written CodePress.run();

The answer was that we needed to add parentheses to CodePress.run and after the fadeIn() call.
$('#content').on('click', '#fileSystemWrap a', function (event) {
event.preventDefault();
var fileName = $(this).data('file');
$('#content').fadeOut(150, function(){
$('#content').load('/?url=developer/edit-file.php&open=' + fileName, function(){
$('#content').fadeIn(150, function(){
CodePress.run();
});
});
});
});

jquery - colorbox - adding a function to the popup

I have a "quick view" feature that captures a dynamic URL also known as "qvURL" and creates a colorbox with it via:
<script type="text/javascript">
$(function(){
$(".quickview_btn").click(function(e){
e.preventDefault();
var qvURL = $(this).attr("href");
$.colorbox({"href": qvURL})
});
$.colorbox.resize();
});
</script>
Now. I need to make some changes in the child window - but it seems the AJAX or whatever is wiping out the entire DOM and anything I load from the parent window doesn't reflect.
For instance - let's say I just want to add a div that says qwerty!
[I'm actually wanting to create an mbox around a Call To Action]
Any insight would be greatly appreciated!
Please note - the URLs it's loading is content that I can not manipulate - so it has to be done in the parent window.
Thanks!
Please see below for my full snippet:
<script>
$( document ).ready(function() {
$('.quickview_btn').click(function(){
//Quickview tracking
$('.quickview').attr('id', 'quickviewClicked-area');
mboxDefine('quickviewClicked-area','quickviewClicked','clicked=Y');
$( 'div.quickview' ).bind( 'click', function() {
console.log('clicked!');
product = $(this).children().attr('href');
console.log(product)
mboxUpdate('quickviewClicked', "link="+product);
});
//thumbnail add to cart tracking
$('div.add-to-cart').attr('id', 'ThumbnailAddToCart-area');
mboxDefine('ThumbnailAddToCart-area','ThumbnailAddToCartClicked','clicked=Y');
$( 'div.qlBtns' ).bind( 'click', function() {
;
mboxUpdate('ThumbnailAddToCartClicked', "clicked=Y");
console.log('mbox updated!')
});
});
});
/*
$(document).ready(function(){
$(qvURL).$colorbox({
iframe : true,
frastIframe: false,
onComplete: function(){
$('.name').html('yeah you got it');
}
});
});
*/
</script>
< script >
$(document).ready(function() {
$('.quickview_btn').click(function() {
//Quickview tracking
$('.quickview').attr('id', 'quickviewClicked-area');
mboxDefine('quickviewClicked-area', 'quickviewClicked', 'clicked=Y');
$('div.quickview').bind('click', function() {
console.log('clicked!');
product = $(this).children().attr('href');
console.log(product)
mboxUpdate('quickviewClicked', "link=" + product);
});
//thumbnail add to cart tracking
$('div.add-to-cart').attr('id', 'ThumbnailAddToCart-area');
mboxDefine('ThumbnailAddToCart-area', 'ThumbnailAddToCartClicked', 'clicked=Y');
$('div.qlBtns').bind('click', function() {;
mboxUpdate('ThumbnailAddToCartClicked', "clicked=Y");
console.log('mbox updated!')
});
});
});
/*
$(document).ready(function(){
$(qvURL).$colorbox({
iframe : true,
frastIframe: false,
onComplete: function(){
$('.name').html('yeah you got it');
}
});
});
*/
< /script>

I see this line in your code:
$.colorbox({"href": qvURL})
and my first question is whether or not that selector is enough. Mind you I am more a middle-ware than a client-side guru, but from my knowledge of jQuery, that selector won't do anything because jQuery can't tell what you mean. See how you used the quotes in the assignment of the click function?
$(".quickview_btn").click(function(e){
e.preventDefault();
if you used $("#colorbox") to get the object (if that is its id) or $(".colorbox" if is is a a class you are targeting.
(I am not an expert, as I said, but those who are agree:
$(".someClass") selects all elements with class name someClass
$("#testButton") selects the element with the id value of testButton
-- Courtesy of the DZone jQuery Ref Card at https://dzone.com/refcardz/jquery-selectors
So it may be that everything else is fine, you just aren't passing your code anything to hook into the colorbox object.

Javascript ignoring if statements

I'm somewhat new to Javascript. I'm trying to make it so that clicking on an image on one page takes you to a new page and shows a specific div on that new page, so I used sessionStorage to remember and booleans to keep track of which image is being clicked. Right now, the code always executes the first if statement, regardless of which image is clicked. This code works fine in normal java so I can't figure out why my if statements are being ignored in javascript. I also tried adding an 'else' at the end, and tried ===. Here's my javscript, and thank you!
sessionStorage.clickedLeft;
sessionStorage.clickedMiddle;
sessionStorage.clickedRight;
function openedProjectFromGallery() {
if(sessionStorage.clickedLeft) {
$(".left-project-pop-up").show();
} else if (sessionStorage.clickedMiddle) {
$(".middle-project-pop-up").show();
} else if (sessionStorage.clickedRight) {
$(".right-project-pop-up").show();
}
sessionStorage.clickedLeft = false;
sessionStorage.clickedMiddle = false;
sessionStorage.clickedRight = false;
}
$("document").ready(function () {
$(".pop-up .x-button").click(function(){
$(".pop-up").hide();
});
$(".project-description .x-button").click(function(){
$(".project-pop-up").hide();
});
$(".left-project-thumb img").on("click", ".left-project-thumb img", function(){
sessionStorage.clickedLeft = true;
sessionStorage.clickedMiddle = false;
sessionStorage.clickedRight = false;
openedProjectFromGallery();
});
$(".profile-left-project img").click(function(){
$(".left-project-pop-up").show(1000);
});
$(".middle-project-thumb img").on("click", ".middle-project-thumb img", (function(){
sessionStorage.clickedMiddle = true;
sessionStorage.clickedLeft = false;
sessionStorage.clickedRight = false;
openedProjectFromGallery();
});
$(".profile-middle-project img").click(function(){
$(".middle-project-pop-up").show(1000);
});
$(".right-project-thumb img").on("click", ".right-project-thumb img", (function(){
sessionStorage.clickedRight = true;
sessionStorage.clickedLeft = false;
sessionStorage.clickedMiddle = false;
openedProjectFromGallery();
});
$(".profile-right-project img").click(function(){
$(".right-project-pop-up").show(1000);
});
});

You are defining function openedProjectFromGallery() with in document.ready . Define it outside document.ready and also give your three booleans some initial value at the top of your code if not initialized with some value or they are empty. I hope this would help.

It is not really answer to your orginal question,as the main issue with your code is, as #njzk2 says, that openProjectFromGallery only being called once, and not on each event, however I wanted to put my two coins on how this code could look like.
This is good example where custom events should be used
$(document).on('showPopup', function( e, popup ) {
$('.'+popup + '-project-pop-up').show()
})
$(document).on('hidePopup', function( e ) {
$('.popup').hide()
})
$('.left-project-thumb img').on('click', function(e) {
$(document).trigger('showPopup', ['left'])
})
$('.right-project-thumb img').on('click', function(e) {
$(document).trigger('showPopup', ['right'])
})
I think you get an idea.
On the other hand, it always nice to use event delegation with a lot of similar events as well as dom data.
<div class='popup' data-popup='left'>
<img />
</div>
$(document).on('click','.popup', function( e ) {
$(document).trigger('showPopup', [$(this).data('popup')])
})

From what I can see openedProjectFromGallery is only getting called on document load.
Add a call to it into each of the event handling functions or use jQuery's delegate function to assign event handling to each image.

jquery event once all images are loaded (including cached images)?

I have the following function which is for ajaxing in a page and the showing it only once all the images are loaded:
$.get('target-page.php', function(data){
var $live = $('#preview_temp_holder').html(data);
var imgCount = $live.find('img').length;
$('img',$live).load(function(){
imgCount--;
if (imgCount==0){
//DO STUFF HERE ONCE ALL IMAGES ARE LOADED
$('#preview_pane').html($live.children()).fadeIn(800);
$live.children().remove();
}
});
});
The problem comes with cached images not firing the .load() event and thus not decrementing the imgCount.
I know i need to implement Nick Craver's solution but am not sure how. Can anyone help me?

I spent a long time looking for solutions for this. The plugin suggested on the jQuery API page (https://github.com/peol/jquery.imgloaded/raw/master/ahpi.imgload.js) did not work in firefox.
My solution was to loop through each image and only add the load event if it was not already loaded (i.e. cached by the browser). The code below includes a counter that I was using to check that load events were only firing for images not already in the cache:
$(document).ready(function () {
var images = $("img.lazy");
$(".image-wrapper").addClass("loading");
var loadedCount = 0;
images
.hide()
.each(function () {
if (!this.complete) {
$(this).load(function () {
loadedCount++;
console.log(loadedCount);
displayImage(this);
});
}
else {
displayImage(this);
}
});
});
function displayImage(img) {
$(img).fadeIn(300, function () {
$(this).parents(".image_wrapper").removeClass("loading");
});
}
I'm no javascript expert so if you spot any problems with this solution please do let me know. As I say, it works in IE8, Chrome and Firefox (not sure about older versions of IE).

Ok, managed to get them merged:
$.get('target-page.php', function(data){
var $live = $('#preview_temp_holder').html(data);
var $imgs = $live.find('img')
var imgCount = $imgs.length;
$imgs.one('load', function() {
imgCount--;
if (imgCount==0){
//DO STUFF HERE
//ALL IMAGES ARE LOADED
$('#preview_pane').html($live.children()).fadeIn(800);
}
})
.each(function() {
if(this.complete){
$(this).load();
}
});
});
note: a 404-ing image would break this.

Change:
$('img',$live).one('load', function(){
...
});
And after above append:
$live.find('img').each(function() {
if(this.complete) $(this).load();
});
Generally I suggest to reuse $live.find('img') from previous count statement.
