Jquery click event don't want to fire - javascript

I have read a lot of questions here about click function and i try to follow the answers, but i can't make it work.
There is definitely logical problem.
Does not matter what is lower the 2nd line, because the console.log doesn't logs anything.
Here is the code:
$('#play')[0].click(function() {
console.log('click');
$("html,body").animate({
scrollTop : arrOfDivs[2].offset().top - 80
}, 700);
return false;
});
Here is jsfiddle: http://jsfiddle.net/W3y88/
Thanks!

i updated your code http://jsfiddle.net/W3y88/3/
$('#play').on("click",function() {
alert('click');
return false;
});

One issue here is that when you declare an ID, you can only use it once on the page. If you want to affect multiple instances, you should consider using classes on those items you want to alter.
Try changing your id to a class, then change your code to:
$('.play').click(function() {
console.log('click');
$("html,body").animate({
scrollTop : arrOfDivs[2].offset().top - 80
}, 700);
return false;});
Of course, I am assuming you have given multiple objects the same id. If you could paste more code, it would be helpful.
A reference on ID's: https://softwareengineering.stackexchange.com/questions/127178/two-html-elements-with-same-id-attribute-how-bad-is-it-really
Alternately, you can remove the [0] if you are referring to a unique ID and your original code may work.

There are few ways you can do this: http://jsfiddle.net/DWU5Y/
But, you had few thigns missing:
The script include for Jquery.
The id is unique so I am not sure why you used $('#id')[0]

JQuery click() event listener not working

im trying to get a lil project going but im stuck on a very annoying thing.
$(document).ready(function() {
$("#search-button").click(console.log('hello'))
});
as you can see im targeting a search button with the id search-button and as soon as i click it something should happen. in this case i put a console.log in to test if it works but it doesn't. it always logs it as soon as i load the page , not when i click the button i target. ... what am i doing wrong
if you need more info on this pls tell me i tried to keep it as simple as i could
ty for your help
O.k
The click handler needs a function argument, not just the console.log by itself. Try this:
$(document).ready(function() {
$("#search-button").click(function() {
console.log('hello');
});
});
Inside of .click should be a handler .click(handler) and the handler should be a function. The browser is reading the code and when it hits console.log('hello'), it does it! It's seeing .click etc, but it doesn't matter; it next sees console.log and does it.
Try
$(document).ready(function() {
$("#search-button").click(function() {
console.log('hello');
});
});
As others have mentioned, the click function requires its own callback function. You can also use this, without requiring the use of document:
$("#search-button").on('click', function() {
console.log('hello')
})
I hope You're using jQuery version 3 or up. if you use 3 or up jquery version the good practice is you use Document binding Example:
jQuery(document).on('click', '#search-button', function(event) {
//your Code here...
console.log('hello');
});

JavaScript alert callback not working inside a function

I am trying to make a image preview containing of about 5-6 images which will appear one after another when user hovers over it (not like a carousel with prev and next buttons). Here is the fiddle consisting of what I gathered so far.. i don't know if this approach is right or not.. but I am stuck as the alert callback is not working. Could someone please tell me what is wrong?
$(function()
{
var imageCount = $('#product_grid_list').find('figure')[0].getElementsByTagName('img');
for (var i = 0, n = imageCount.length; i < n; i++) {
imageCount[i].on('click', function(e)
{
alert('Everything is going fine!');
}
);
}
}
);
The root cause of click event callback can't be triggered is that you're trying to register a event handler on a "DOM" (in this case: imageCount[i]) element in jQuery way. Try to register the event handler like this if you want to use pure javascript solution:
imageCount[i].addEventListener('click', function(e){
alert('Everything is going fine!');
});
Here is a jsfiddle demo.
Note: I didn't consider the cross browser issue in this case.
BTW, try to cache the length of imageCount node list, it will improve the performance.
You are using js AND jQuery at same time. It's wrong. If you use jQuery, than click event will be like this:
$(document).('click', '#product_grid_list figure img', function(){
alert('Everything is going fine!');
});
You are using a mix of jQuery and standalone javascript. You might as well go all the way to jQuery, with something like:
$('#product_grid_list figure:first img').click(function(e) {
alert('Everything is going fine, hopefully!');
});
You did not send the corresponding HTML, so we cannot test whether the above is correct.
it's just a simple click event in jQuery, no need to use js: http://jsfiddle.net/wP3QQ/11/
$('#product_grid_list').find('figure img').click(function(e){
alert('Everything is going fine!');
e.preventDefault();
});
You want the hover effect, so click event should not be used over here. It should be mouseover.
Working Fiddle
Code Snippet:
$(document).on('mouseover','#product_grid_list figure img',function(e){
alert("now it is working");
});
You are attempting to call on(), a jQuery method, on an HTMLElement (a DOM element). You can't do that, jQuery methods can only be called on jQuery collections. It's easy to get a jQuery collection for the elements you desire:
Use .find() to match the images
There's no need for a for() loop, jQuery's .on() will handle looping for you.
You may also want to prevent the default behaviour of your anchors
$(function () {
var imageCount = $('#product_grid_list').find('figure img');
imageCount.on('click', function (e) {
e.preventDefault()
alert('Everything is going fine!');
})
});

Toggling one thing with two different elements

In my previous question I asked about how can I toggle a textarea with a paragraph. I got the answer. Now I want to do the opposite of it. First I was showing the already hidden textarea + 2 buttons by a click of a hyperlink. Now on the click of one of the buttons I want to hide the text + 2 buttons and show the paragraph that was first already shown.
I have tried this JS so far but it's not working:
$(document).ready(function () {
$(".no_link").click(function (e) {
e.preventDefault();
});
$(".edit_offer").on('click', function () {
toggleEditPanel($(this));
});
$("#cancel_edits").on('click', function () {
$(this).closest("button").hide();
$(this).closest("textarea").hide();
$(this).closest("p.content").show();
});
});
function toggleEditPanel(link) {
link.parent().parent().parent().find("textarea").toggle();
link.parent().parent().parent().find("button").toggle();
link.parent().parent().parent().find("p.content").toggle();
}
But its not working. How can I solve this error?
If I am trying to call the function toggleEditPanel() again. Its not working then aswell.
You can find the markup in the fiddle. Here's the fiddle.
UPDATE 1:
Just came up with a solution. I can use the $.siblings() function to toggle the elements beside the button. Still, is there any better solution?
Here's the code that I came up with:
$("#cancel_edits").on('click', function () {
$(this).hide();
$(this).siblings("button").hide();
$(this).siblings("textarea").hide();
$(this).siblings("p.content").show();
});
UPDATE 2:
The problem in the above code is that if there are more than one panels like this then the code is not working. How can I solve that issue aswell?
You are using Id for selector $("#cancel_edits") .
Id selectors returns only first element , so if there are multiple pannel it will work only for first.
Instead give some class name and use it for selector. Further you can use chaining and caching in your code for better performance.
$(".cancel_edits").on('click', function () {
var elm=$(this);
elm.add(elm.siblings("button,textarea")).hide();
elm.siblings("p.content").show();
});
I would recommend referencing your elements by ID:
$("#cancel_edits").on('click', function () {
$('#save_edits').hide();
$('#edited_content').hide();
$(this).hide();
$("p.content").show();
});
JSFiddle
The great thing about using IDs is that you are guaranteed they are unique - no need to use closest() to find the element you want. If, however, you're using classes instead, closest() might be necessary or helpful.

How can I access the parent in the jquery on selector

I have the following jQuery code:
$('#temp_modals').on('mouseleave','*[data-username]',function() {
///my logic
});
However I need to to have the mouseleave event on the the parent div of *[data-username].
As this element is added dynamically to the webpage I cannot use a normal selector and need to use the $.on.
In short I want to achieve that code like this runs.
$('#temp_modals').on('mouseleave','*[data-username]'.parent(),function() {
///my logic
});
How can I do that?
Try
$('#temp_modals').on('mouseleave','*:has(> [data-username])',function(event) {
///my logic
// this should get you the parent.
$(event.target).parent();
});
Demo: Fiddle
According to the spec this should work
http://api.jquery.com/parent-selector/
$('#temp_modals').on('mouseleave','*[data-username]:parent',function() {
///my logic
});
EDIT : Indeed this won't work, thanks for pointing it out, :parent doesn't do what i was expected. This will work :
$('#temp_modals').on('mouseleave',$('*[data-username]').parent(),function() {
console.log(this)
});

Javascript + jQuery, click handler returning false to stop browser from following link

I'm trying to stop the browser from following certain links, rather I want to unhide some Divs when they are clicked.
I'm having trouble just getting the links to not be followed though.
Here's what I have:
var titles = $('a.highlight');
jquery.each(titles, function(){
this.click(function(){
return false;
});
});
It seems like the click handler is not being assigned. What am I missing?
Try
this.click(function(e){ e.preventDefault(); }
Actually, it looks like you might need to use the jQuery constructor on this:
$(this).click(function(){ return false; }
You could also try using parameters on the each function instead of using this:
jQuery.each( titles, function(index, elem) { $(elem).click( function() { return false; } ) } );
Personally, I would just do titles.each( ... though. In that instance you can use this to bind the click handler. I am not sure off the top of my head what this binds to with jQuery.each
Or just calling click on titles:
titles.click( function() { return false; } )
That will bind click to every element in titles. You don't need to loop through them.
You can compress that jquery a bit:
$('a.highlight').click(function() { return false; });
You should also make sure that:
There are no other click handlers registered for those elements later on.
The code you have is attaching after the elements have loaded. If they're not completely loaded, they won't be found in the $('a.highlight') selector. The easiest way to do this is to put your code in a $(document).ready(function() { *** code here *** }); block.
Edit: As per other responses - the problem was that this represents a DOM object, while $(this) is a jquery object. To use the .click function to attach a handler, you need a jquery object.
In short, using this inside the each loop won't work with what you're trying to do. You'll need to get a jquery representation by using $(this) instead.
