jQuery selector for element not on page

I have the following jQuery on the page:
$('#nav-icon1,#nav-icon3').click(function(){
});
And corresponding HTML like this:
<div id="nav-icon3" class="">
<span class="whitehamburger origin"></span>
<span class="whitehamburger origin"></span>
<span class="whitehamburger origin"></span>
<span class="whitehamburger origin"></span>
</div>
There's no nav-icon1 anywhere on the page, but when I change the jQuery to be this:
$('#nav-icon3').click(function(){
});
It stops working.
What am I missing? Thanks!

it's necessary attach that event to your div? check if your spans are position "relative" because if they are "absolute" your div "nav-icon3" may not be visible with height:0px.
another way to add events is using "bind"
$(function(){
$("#nav-icon3").bind('click', function()
{
// some code...
});
});
or
$(function(){
$("#nav-icon3").bind('click', _onNavClick);
});
function _onNavClick(event)
{
// some code...
}

It seems different error, what you are doing is working just how it is. Check it here jsfiddle.net/ed9xsh62/ Check your console or share URL to check the exact error.

$(function(){
$( "#nav-icon3" ).click(function() {
//code goes here
//can do a simple alert to test the function
});
});
Could be a possibility that you just did not have your code in document.ready function (I used the shorthand version). I tried your code and it worked perfectly as long as it was in the document.ready function.

onClick eventlistener in JS without using onclick function in HTML

I have a html file and js file I want to execute JS when a button is clicked in html. for this I can use onclick event in html but the condition is that I should not modify the HTML file.
I tried to add eventlistener in my JS but that didn't worked.
<p align=center>
<button class="stdbutton" id=button2 name=button2>
Click Me
</button>
</p>
$("button2").click(function() {
alert("button2 clicked");
});
please see the fiddle link for further reference: http://jsfiddle.net/gqpr0g9w/
thanks in advance

Try the FIDDLE,
Basically the first issue with your fiddle was you are using js library other than jquery. Jquery code won't execute without referencing the jquery library.
Secondly you are using an invalid selector,
$("button2")
you can replace this with an id based selector (# selector) as per your markup
$("#button2")
And finally try wrapping the code under jquery closure under document ready event that will ensure that the event will attach when the related object is loaded on the browser.
Finally will becomes
$(document).ready(function() {
$("#button2").click(function() {
alert("button2 clicked");
});
});
Hope it works for you..

Include jQuery in your jsfiddle. Use one of the below to attach an event listener for click using jQuery
$("#button2").on("click", function() {
alert("button 2 clicked");
});
or
$("#button2").click(function() {
alert("button2 clicked");
});

case jQuery is included in the html:
js file -
$("#button2").click(function() {
alert("button2 clicked");
});
// notice the # symbol before the word "button2" representing that we are looking for an ID
case jQuery is NOT included in the html:
<script src="lib/jquery-2.1.4.min.js"></script>
<script src="js/myJavaScript.js"></script>
jQuery script must first be included
and then you can execute the same code as shown above.

Well, you are trying to use jQuery, but there is no jQuery included in your html-File. In fact there is no script included in your html at all like
<script src="lib/jquery-2.1.4.min.js"></script>
<script src="js/myJavaScript.js"></script>
I don't think you will be able to do that without modifying the html-file.

on click for jquery not being recognized

I have done on hover and on click with jQuery plenty of times, but this is baffling me. I have the jQuery library imported, and I have the following:
$(document).ready(function() {
$('.content_main_left_bottom').bind("click", function(e) {
alert('hi');
});
});
For some reason, it's NEVER reaching the alert!! I even put the alert right above document and it's showing there. I have the div tag with content_main_left_bottom within my code somewhere, is there something else I should do with that class?

jQuery(document).ready(function($) {
$('.content_main_left_bottom').bind("click", function(e) {
alert('hi');
});
});
first i would try this if the element with CLASS name (not ID) content_main_left_bottom exists it should work fine ...except you have any other javascript error in the code which you can find out by pushing f12 in your browser and go to the console section

Using jQuery to change the background image

I am trying to change the background image of a link when it get clicked. I keep getting the error that you cannot call 'click' on null.
JQuery (in the header)
<script type="text/javascript">
$('a.upvote-arrow').click(function(){
$('#tempid1').css('background-image','url(../images/icons/up-arrow2.png)');
});
</script>
HTML
<div class="top-comment-vote">
</div>
Thanks

Try adding $(document).ready:
<script type="text/javascript">
$(document).ready(function(){
$('a.upvote-arrow').click(function(){
$(this).css('background-image','url(../images/icons/up-arrow2.png)');
});
})
</script>

Are you sure this script is being loaded after the html is in the DOM?
Try wrapping what you wrote in a onload closure.
$(function() {
$('a.upvote-arrow').click(function(){
$('#tempid1').css('background-image','url(../images/icons/up-arrow2.png)');
});
});
Another thing you can do is take advantage of delegation for the event registration.
$('body').on("click", ".a.upvote-arrow", function(){
$('#tempid1').css('background-image','url(../images/icons/up-arrow2.png)');
});
This binds it to the body instead.

Try wrapping your script with document.ready; I suspect that you're script might be running before your entire page loads.

Toggle text with function called with onclick

my question is a short one but I couldn't figure it out by myself. I've got a function like -> http://jsfiddle.net/gtU56/ . I'm calling a javascript-function with an event-listener(onclick) in my html-code. The function itself is more complex but I need the last snippet. By clicking 'Show More' the text should change. Why won't the text change?

Because the toggleText function isn't available when the html code is rendered.
In other words the function isn't set until the page is ready so the onclick function doesn't reference anything.
Either have the function like here http://jsfiddle.net/gtU56/2/
or have it in the head of the page because its needs to be ready immediately
If you want it to wait for the ready state you can do the following and remove the onclick action all together
http://jsfiddle.net/gtU56/7/
$(".text").click(function()
{
$(".text").toggle();
});

toggleText = function () {
$('.text').toggle();
}
check here http://jsfiddle.net/gtU56/3/

It's because of how you're loading the function. Switch it from onLoad to no wrap (head) and it works fine.
jsFiddle example
Using jsFiddle's onLoad wraps your function in a window.onload call like this:
<script type="text/javascript">
//<![CDATA[
$(window).load(function(){
function toggleText() {
$('.text').toggle();
}
});//]]>
</script>
While no wrap (head) just adds it normally like this:
<script type="text/javascript">
//<![CDATA[
function toggleText() {
$('.text').toggle();
}
//]]>
</script>

since you are already claiming having jquery, you need not use inline javascript. try this
var elems = $('.text');
elems.click(function(){
elems.toggle();
});
fiddle : http://jsfiddle.net/gtU56/5/

$('.text').click(function() {
$('.text').toggle('slow', function() {
// do your animation..
});
});
​
Js Fiddle

This is the solution - http://jsfiddle.net/gtU56/6/
You need to first make sure that the function is registered after page load. Then, bind a click event to the div.
Hope this helps!

First you should organize you jQuery code like this:
$.(document).ready(function() {
// enter jQuery code here
});
Otherwise you're accessing a not completly loaded html document.
Also, you don't need the event-listener if you are using jQuery.
This should work for you:
$.(document).ready(function() {
$('.text').click(function() {
$(this).toggle();
});
});

Is very easy. You can use ID or CLASS.
onclick="$('NAME ID or CLASS').toggle(ANIMATION or DURATION);"
<div>
<div class="text" onclick="$('.text2').toggle(400);">Show More</div>
<div class="text2" style="display:none">Show Less</div>
</div>
