Why my `onclick` doesn't work despite others things works?

So I'm using some parts of gentelella and there is a file custom.js. I have some problems with this file because some parts works and other don't.
The problem is with this method:
$(document).ready(function() {
console.log("custom.js inside document ready");
$('.collapse-link').on('click', function() {
console.log("clicked on a collapse-link");
var $BOX_PANEL = $(this).closest('.x_panel'),
$ICON = $(this).find('i'),
$BOX_CONTENT = $BOX_PANEL.find('.x_content');
// fix for some div with hardcoded fix class
if ($BOX_PANEL.attr('style')) {
$BOX_CONTENT.slideToggle(200, function(){
$BOX_PANEL.removeAttr('style');
});
} else {
$BOX_CONTENT.slideToggle(200);
$BOX_PANEL.css('height', 'auto');
}
$ICON.toggleClass('fa-chevron-up fa-chevron-down');
});
$('.close-link').click(function () {
console.log("close-link clicked")
var $BOX_PANEL = $(this).closest('.x_panel');
$BOX_PANEL.remove();
});
});
It write "custom.js inside document ready" but when I click nothing happened.
And if I look into the HTML I have the same classes as in the JS:

it might be that on document ready these specific elements are not found.
In general a best practice is to delegate the events to the document, like this:
$(document).ready(function() {
console.log("custom.js inside document ready");
$(document).on('click', '.collapse-link' /* <--- notice this */, function() {
console.log("clicked on a collapse-link");
var $BOX_PANEL = $(this).closest('.x_panel'),
$ICON = $(this).find('i'),
$BOX_CONTENT = $BOX_PANEL.find('.x_content');
// fix for some div with hardcoded fix class
if ($BOX_PANEL.attr('style')) {
$BOX_CONTENT.slideToggle(200, function(){
$BOX_PANEL.removeAttr('style');
});
} else {
$BOX_CONTENT.slideToggle(200);
$BOX_PANEL.css('height', 'auto');
}
$ICON.toggleClass('fa-chevron-up fa-chevron-down');
});
$(document).on('click', '.close-link' /* <--- notice this */, function () {
console.log("close-link clicked")
var $BOX_PANEL = $(this).closest('.x_panel');
$BOX_PANEL.remove();
});
});

You have written the click event on the a tag. In general functional specific tags like submit button, a tag will do their default functionality on click. So as it is anchor it will check for href which is not there so the it is not redirecting to anywhere. We can supress the default behaviour of these kinds using e.preventDefault(). Here e is the event. So change your function to
$('.collapse-link').on('click', function(e) {
e.preventDefault();
console.log("clicked on a collapse-link");
var $BOX_PANEL = $(this).closest('.x_panel'),
$ICON = $(this).find('i'),
$BOX_CONTENT = $BOX_PANEL.find('.x_content');
// fix for some div with hardcoded fix class
if ($BOX_PANEL.attr('style')) {
$BOX_CONTENT.slideToggle(200, function(){
$BOX_PANEL.removeAttr('style');
});
} else {
$BOX_CONTENT.slideToggle(200);
$BOX_PANEL.css('height', 'auto');
}
$ICON.toggleClass('fa-chevron-up fa-chevron-down');
});
And
$('.close-link').on('click', function(e) {
e.preventDefault();
console.log("close-link clicked")
var $BOX_PANEL = $(this).closest('.x_panel');
$BOX_PANEL.remove();
});

Instagram api is not working

I have very few knowledge about using api, javascript.
(I'm a html/css coder)
I've been requested to use this API to get instagram pictures
that users posted using certain hashtag.
Here's the demo that's been shared by jsfiddle
http://jsfiddle.net/j9ynxvox/10/
$(function() {
// 「表示」を押すと、画像を取得します
var endpoint = 'https://tagplus.jp/demo/api/json/medias';
// ポップアップ用の関数
var popup = function(item) {
var $container = $('<div>', {'class': 'popup-container'});
$('<div>', {'class': 'popup-overlay'}).appendTo($container);
var $template = $($('#popup-template').html());
$template.find('.popup-image').attr('src', item.images.standard_resolution);
var userLink = 'https://instagram.com/' + item.media_user.username;
$template.find('.user-link').attr('href', userLink);
$template.find('.profile-picture')
.attr('src', item.media_user.profile_picture);
$template.find('.media-user-name').text(item.media_user.username);
$template.appendTo($container);
$('body').append($container);
$container.fadeIn();
};
$(document).on(
'click',
'.popup-overlay',
function(e) {
e.preventDefault();
$('.popup-container').fadeOut(
'fast',
function() {
$(this).remove();
}
);
}
);
$('button').click(function() {
$('#thumbnail').text('');
$.get(
endpoint,
{count: 12},
function(res) {
res.data.forEach(function(item) {
var $thumb = $('<img>', {
'class': 'insta-thumb',
src: item.images.thumbnail
});
$thumb.appendTo($('#thumbnails'));
$thumb.click(function(e) {
e.preventDefault();
popup(item);
});
});
},
'jsonp'
);
});
$(document).keyup(function(e) {
if (e.keyCode === 27) {
$('.popup-container').fadeOut(
'fast',
function() {
$(this).remove();
}
);
}
});
});
In my case, I've been asked to use this API address. https://tagplus.jp/plazastyle_Campaign/api/json/medias
(its called http://tagplus.jp/)
To start off, I simply copied and pasted this jsfiddle code
to my local files but it is not working when I click the button to load instagram pictures.
Here's my demo
http://1ne-studio.com/test2/sample.html
id : test
pass : ny2016
Why is it not working and how could I fix this?
Thank you for your time!

EDIT: So it looks like your script is totally different from the one in the fiddle. Replace your script to the one from the fiddle and try again!
Old answer:
It's because you do not have jQuery!
Add this somewhere in the head and try again
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>

jqueryui slider not working inside bootstrap popover

i have number of bootstrap popover and some of them have jqueryui slider as content of the bootstrap popover and that slider is not working
Fiddle
https://jsfiddle.net/yasirhaleem/43qfkjtb/
$( document ).ready(function() {
$('.triggerOverlay').popover({
html : true,
content: function() {
var $this = $(this);
var cont = $this.data('toggle');
return $('#'+cont).html();
},
trigger: 'manual'
}).click(function() {
$('.slider').slider();
});
$(document).on('click', function (e) {
// always hide them all.
var popov = $(".popover");
if (!popov.is(e.target) && popov.has(e.target).length==0 ){
$('.triggerOverlay').popover('hide');
} // if e.target has a popover toggle it.
if ($(e.target).hasClass('triggerOverlay')) {
$(e.target).popover('toggle');
}
});
$( "#slider" ).slider();
});

found the solution to my question posting reply to my own question hope it will be helpful for others.
if someone has better solution please post or suggest in comments.
here is the fiddle https://jsfiddle.net/yasirhaleem/s1ytug1c/
this fiddle http://jsfiddle.net/mmfansler/5kuB8/9/ was not helpful for me i had different schenario, my html was already generated i was using different solution for popover and than we decided to use bootstrap popover and we run into this problem.
All i needed was a callback function below code extend the popover and adds callback function
Extending popover
var tmp = $.fn.popover.Constructor.prototype.show;
$.fn.popover.Constructor.prototype.show = function() {
tmp.call(this); if (this.options.callback) {
this.options.callback();
}
}
Popover Call
$('.triggerOverlay').popover({
html : true,
callback: function () {
$('.slider').slider();
},
content: function() {
var $this = $(this);
var cont = $this.data('toggle');
return $('#'+cont).html();
},
trigger: 'manual'
});
HTML
button<br><br><br><br><br>
<div id="user-profile-overlay" class="customoverlay">content goes here<div class="slider"></div>
</div>

Use the same button to trigger two different JQuery events

I am trying to use the same button to trigger an ajax call to add a database entry if it is clicked and then trigger a different ajax call to remove the entry it is clicked again.
I have tried using toggleClass and although the button class does change and it's appearance changes accordingly the function still thinks it has the old class name.
$(document).ready(function() {
$(".selected").on("click", function() {
$(this).text(function (i, oldText) {
return $.trim(oldText) == 'Use Image' ? 'Selected' : 'Use Image';
});
$(this).toggleClass('selected selected_btn');
});
$(".selected").on("click", function() {
alert('selected');
});
$(".selected_btn").on("click", function() {
alert('de selected');
});
});
With the present code the alert is always 'selected'.

$(document).ready(function() {
$(".selected_btn").on("click", function() {
$(this).text(function (i, oldText) {
return $.trim(oldText) == 'Use Image' ? 'Selected' : 'Use Image';
});
$(this).toggleClass('selected');
if($(this).hasClass("selected"))
alert("Selected")
else
alert("de-Selected")
});
});
here is a fiddle:
http://fiddle.jshell.net/prollygeek/3LLN2/

Here is a simple and readable example on how to do this:
$(document).ready(function() {
$('.select-img').on('click', function(){
var $el = $(this);
var isSelected = $el.attr('data-selected');
if( isSelected != 'true' ){
firstFn();
$el.html('Use Image').attr('data-selected', true)
}else{
secondFn();
$el.html('Select').attr('data-selected', false)
}
})
var firstFn = function(){
alert('first thing to do');
}
var secondFn = function(){
alert('second thing to do');
}
})
Demo

Use *Class functions:
hasClass
removeClass
addClass
Working code:
$("a").on("click", function() {
if($(this).hasClass("bob")) {
// do delete
alert("delete");
$(this).removeClass("bob");
} else {
// do insert
alert("insert");
$(this).addClass("bob");
}
});
Demo

$(".selected").on("click", function() {
alert('selected');
});
Overrides the event you put on the beginning of the document.ready, I think.
(might not be true, but I think it is)

jQuery not working in IE, works in other browsers

Currently coding a mates portfolio and not to my surprise the code isn't loading in IE!
I'm coding it using standard AJAX, here's the relevant jQuery:
//ajax shtuff
$(window).load(function() {
// Ajax Cache!
$.ajaxSetup ({
cache: false
});
var $loadW = '<div id="whiteLoader" />';
var $loadurl = $('.current').attr('href');
// Initial Page Load
$('#con').prepend($loadW);
$('#main').fadeOut('slow', function() {
$(this).load($loadurl + ' .page', function() {
$(this).parent().find('#whiteLoader').fadeOut('slow', function() {
$(this).parent().find('#main').fadeIn('slow').css({background: 'red'});
$(this).remove();
});
});
});
$('nav ul li a').each(function() {
$(this).click(function(e) {
var $loadW = '<div id="whiteLoader" />';
var $loadurl = $(this).attr('href');
// Prevent default hotlink
e.preventDefault();
// Add the current state
$('*').removeClass('current');
$(this).addClass('current');
// Load the Page
$('#main').fadeOut('slow', function() {
$('#con').prepend($loadW);
$('#main').load($loadurl + ' #main', function() {
$('#whiteLoader').fadeOut('slow', function() {
$('#main').fadeIn('slow');
$(this).remove();
});
});
});
});
});
});
Literally have no idea why this doesnt work lol, here's a link to the live page (I've put the background as red just to show you the area.)
Also the reason the initial page is using the 'this' method is because I was testing it both ways.

have you tried
$(document).ready(function() {
// Stuff to do as soon as the DOM is ready;
});
instead of window.load?

Often IE has trouble styling / selecting any of the new HTML5 elements such as section and nav. Try using something like this or simply using a div
