jQuery button click only working once

I'm trying to use jQuery to hide and show elements on a button click. I have the following code:
$(function(){
$('#link-form').hide()
$('#link-submit').hide()
$('#main-header-submit').on("click", function() {
$('#link-form').show();
$('#main-yield').fadeTo("fast", 0.2)
$(this).on("click", function() {
$('#link-form').hide()
$('#main-yield').fadeTo("fast", 1)
})
})
})
This successfully shows and hides the divs when I click the 'main-header-submit' button, but when I click the button (effectively for a third time) to make the elements show again nothing happens. Any help much appreciated.

If you rewrite your code like this, it should work:
$(function(){
$('#main-header-submit').on("click", function() {
$('#link-form').toggle("fast");
})
})
The toggle function hides the elements if they are shown and shows them if they are hidden. Check here http://api.jquery.com/toggle/

The issue is because you're attaching another click handler on each successive click. The first shows the link-form, while the second hides it. This is why you never see any change.
From what I can see of your code, to achieve what you require you simply need to use toggle() and fadeTo() with a ternary instead. Try this:
$('#main-header-submit').on("click", function() {
$('#link-form').toggle();
$('#main-yield').fadeTo("fast", $('#main-yield').css('opacity') == '1' ? 0.2 : 1);
});
Working example

Essentially, using $("selector").on('click', function() { ... }); will run the ... on the click event for that element.
Inside the ... function definition, you're overwriting the .on('click') by another function.
So in other words, the first time you click, you're telling the code to show your element, then rebind the click to hide. So every subsequent click will hide the already hidden element.
What you need to do is to something like this:
$('#main-header-submit').on("click", function() {
if ($(this).is(":visible")){
$('#link-form').hide()
$('#main-yield').fadeTo("fast", 1)
}
else{
$('#link-form').show();
$('#main-yield').fadeTo("fast", 0.2)
}
});

use toggle() and fadeToggle
$('#main-header-submit').on("click", function() {
$('#link-form').toggle();
$('#main-yield').fadeToggle("fast")
})

Dynamically created div behavior on button click

I went through many post from SO but not able to relate with my scenario.
I have this code on button click. by which User can create as many div on runtime as he wants to on UI.
$('#adddiv').click(function () {
debugger;
$('#main').append('<div class="ara-dynamic-div">
<div class="box box-solid bg-light-blue-gradient">
</Div></div>');
});
code to get buttonclick event from that div
$(document).on('click', '#remove', function () {
showMakeAndHold(this);
});
function showMakeAndHold(obj) {
alert(obj);
$('.ara-dynamic-div').fadeOut();
}
Now the problem is that I have to create multiple dynamic div. and each div will have button to close itself. When I call this function it will close all created div's instead of the one which button is clicked.
I am not able to find the proper div by which request for close come. I am new to DOM and JQuery. not able to relate the things

First of all, if you're using multiple divs you shouldn't give the close button an ID, but a class instead (let's say, .close)
Next you can use event delegation to find the correct element:
$(document).on('click', '.ara-dynamic-div .close', function( event ) {
$(this).closest('.ara-dynamic-div').fadeOut();
} )
The delegator handles all click events in any .ara-dynamic-div .close button, catching them all and allowing you to use $(this).closest(...) to get to the parent container.
Edit: Corrected a mistake

You can use jQuery's .closest() function.
function showMakeAndHold(obj) {
alert(obj);
$(obj).closest('.ara-dynamic-div').fadeOut();
}
JSFiddle

Replace this:
$(document).on('click', '#remove', function () {
showMakeAndHold(this);
});
by this:
$(document).on('click', '#remove', function () {
$(".ara-dynamic-div").not($(this).parents(".ara-dynamic-div")).fadeOut(function () {
$(this).remove();
});
});
Here is the JSFiddle demo
What the code does is that it remove all other .ara-dynamic-div except the one for which the button was clicked.

Two OnClick events overlap, causing the first one to stop executing properly

I am trying to fit a new jQuery toggle function within an already working code. Basically, the toggle function should show/hide the below lying div form_fields_con with an onclick event.
The problem is that the form_fields_con div contains AJAX functionality triggered as well with an onclick event.
Toggle works when nothing in the form_fields_con div is changing but once clicked, the toggle function stops working.
This is the toggle function:
$(document).ready(function() {
$(".slidingDiv").hide();
$(".show_hide_search").show();
$('.show_hide_toggle').on('click', function(e) {
e.preventDefault();
var self = this,
sliding = $(this).closest('div').next('.slidingDiv').slideToggle(function() {
$($(self).children()[0]).text(function(_, txt) {
return txt == "–" ? "+" : "–";
});
});
});
});
And this is the AJAX one contained in form_fields_con div:
function selectcombobox(fuelcombobox, fuelid, fuelContainer, field_name) {
var popupvar = jQuery.noConflict();
popupvar('#'+fuelcombobox).css('display', 'none');
popupvar('#'+fuelid).css('display', 'block');
popupvar('#'+fuelContainer).css('display', 'none');
}

How to prevent the two onclick functions' collision?

You change/recreate the DOM elements holding the onClick listener, a simple approach to get around your problem is event-delegation: http://api.jquery.com/on/ (see se second argument)
$('.slidingDiv').on('click', '.select_con_car', function() {
alert('clicked');
});

Detecting class on HTML element not working correctly

I have a button and when it is clicked it should add a class to the HTML element, but then when the .class is clicked, it isn't detected.
This is the use case:
Click button - "testerclass" will be added to HTML element
Click "testerclass" - removes that class from that element
The detection for when "testerclass" is clicked only seems to work when the class exists before the page load, not when I add the class manually after load. Is this something to do with the problem?
I have tried to recreate the problem on jsfiddle, but I can't recreate the use case where the class is already added to the HTML element, as I can't edit that on jsfiddle.
But here is jsfiddle one, In this one you can see that the buttonone adds a class to HTML, but the detection for clicks on .testerclass never come through.
And here is jsfiddle two. In this one, I have changed the .testerclass selector to html, and this shows that HTML clicks are bubbling through (which I was unsure of when I first hit this problem).
And offline I created a third testcase where the HTML element already had the testerclass, and it detected the clicks sent through to it.
$(document).ready(function() {
$('button.1').click(function() {
$('html').addClass('testerclass');
$('.test').append('"testerclass" added to html<br />');
});
$('.testerclass').click(function() {
$('.test').append('testerclass clicked and removed<br />');
$('html').removeClass('testerclass');
});
});
Edit: I also tried doing this with a slightly different method of:
$('html').click(function() {
if(this).hasClass('testerclass') {
//do stuff
}
});
but that didn’t work either.

Since the testerclass is dynamic, you need to use event delegation to handle events based on that. Which will require us to register the event handler to the document object that causes another problem because the click event from the button will get propagated to the document object which will trigger the testerclass click handler as well. To prevent this from happening you can stop the event propagation from the button.
$(document).ready(function () {
$('button.1').click(function (e) {
e.stopPropagation();
$('html').addClass('testerclass');
$('.test').append('"testerclass" added to html<br />');
});
$(document).on('click', '.testerclass', function () {
$('.test').append('testerclass clicked and removed<br />');
$('html').removeClass('testerclass');
});
});
Demo: Fiddle

You need to stop the propagation to the html so the other click handler does not pick it up.
$('button.1').on("click", function(evt) {
$('html').addClass('testerclass');
$('.test').append('"testerclass" added to html<br />');
evt.stopPropagation();
});
$(document).on("click", function() {
$('.test').append('testerclass clicked and removed<br />');
$('html').removeClass('testerclass');
});
Other option would be to add one event handler and use the event target to see if it is the button or not and change the content that way.
$(document).on("click", function (evt) {
var isButton = $(evt.target).is(".btn");
var message = isButton ? '<p>"testerclass" added to html</p>' : '<p>"testerclass" clicked and removed</p>'
$('html').toggleClass('testerclass', isButton);
$(".test").append(message);
});
JSFiddle: http://jsfiddle.net/69scv/

here's a neat way to do it
$('html').on('click', function(e) {
var state = !!$(e.target).closest('button.1').length;
var msg = state ? 'class added' : 'class removed';
$(this).toggleClass('testerclass', state);
$('.test').append(msg + '<br>');
});
FIDDLE

You add a class to html element, so when this class is clicked, it means the html element is click. Now the problem is when you click any where in page, it will remove this class away from html! Let try add this class to body element instead.
$(document).ready(function() {
$('button.1').click(function() {
$('body').addClass('testerclass');
$('.test').append('"testerclass" added to html<br />');
});
$('.testerclass').click(function() {
$('.test').append('testerclass clicked and removed<br />');
$('body').removeClass('testerclass');
});
});
And now you can check it:
$('html').click(function() {
if(this).hasClass('testerclass') {
//do stuff
}
});

jQuery FadeOut function

I'm trying to add a fadeOut function which links to another. CLICK HERE At present I have a flashing logo. When the user clicks on the logo, the flashing stops, has a slight delay then slowly fades Out. Is there anyone out there that is able to correct me on the code I have pasted below?
<script>
$(document).ready(function(){
$("#center-gif").click(function(){
$('#center-gif').hide();
$('#center-img').show();
});
$('#center-img').click(function(){
$('#center-img').hide();
$('#center-img-gif').show();
});
$('flash-link').click(function(){
$('center-img').fadeOut(5000);
});
});
</script>

If you want to access element with class/id; you must always define . and # these at the begining, like css.
Some Examples:
$('img').fadeOut();//selects all img elements
$('.img').fadeOut();//selects all elements with class="img"
$('myClass').fadeOut(); //false
$('.myClass').fadeOut(); //true
$('myId').fadeOut(); //false
$('#myId').fadeOut(); //true
Here is working jQuery for your question with less code:
$(document).ready(function(){
$("img").click(function(){
var takeId = $(this).attr('id');//takes clicked element's id
$('img').hide();//hides all content
$('#'+takeId).show();
//matches clicked element's id with element and shows that
});
$('#flash-link').click(function(){//define '#' id declaration here
$('#center-img').fadeOut(5000,//new function after fadeOut complete
function() {
window.open('url','http://iamnatesmithen.com/jukebox/dancers.php');
return false;
});
);
});
});

So I assume your problem is that that image does not fade out, right?
This could solve it:
First of all change your .click()-functions to that:
$().click( function(event) {
// cour code
event.preventDefault();
}
And than change the last one like that:
$('#flash-link').click( function(event) {
$('#center-img').fadeOut( 5000, function() {
window.location.href = 'jukebox/dancers.php';
});
event.preventDefault();
});
I didn't test that, but it should work. What it does is: It fades out the image and calls a function when ready. This functions then redirects to your next page.
The event.preventDefault(); will tell the browser not to delegate the click-event. If you don't put it there, the browser opens the anchor without waiting for any JavaScript to execute.
Note
When you want to select an element with an ID use this selector: $('#[id]')as this selector $('html')works only with HTML-elements.
