div with an id wont accept any event handlers JavaScript. No Jquery

Im trying to pause a timed slideshow when you're hovering over a div
<div id="play_slide" onMouseOver="clearTimeout(playTime)"></div>
If i put onMouseOver="clearTimeout(playTime)" inside an li on the page, it'll pause, so I know my code is correct, it just wont work on the div! Also if i get rid of the id, it will alert when i put an alert function into an event handler
This is the js.
var playTime;
function playSlide()
{
var slideshow = document.getElementById("play_slide").style;
var images = new Array("an", "complete", "red", "thirteen");
indexPlay++;
if(indexPlay > images.length - 1)
{
indexPlay = 0;
}
slideshow.backgroundImage = "url('assets/images/play/"+images[indexPlay]+".png')";
playTime = setTimeout("playSlide()", 2500);
}
you can see this here: www.nicktaylordesigns.com/work.html

I would do it like this:
( and no inline script... just <div id="play_slide">Something</div> )
var playTime;
var indexPlay = 0;
var slideElement;
window.onload = function () {
slideElement = document.getElementById("play_slide");
slideElement.addEventListener('mouseenter', function () {
console.log('stop');
clearTimeout(playTime);
});
slideElement.addEventListener('mouseleave', function () {
console.log('continue');
playTime = setTimeout(playSlide, 2500);
});
playSlide();
}
function playSlide() {
var slideshow = slideElement.style;
var images = new Array("an", "complete", "red", "thirteen");
indexPlay++;
if (indexPlay > images.length - 1) {
indexPlay = 0;
}
slideshow.backgroundImage = "url('assets/images/play/" + images[indexPlay] + ".png')";
playTime = setTimeout(playSlide, 2500);
}
Fiddle

This issue is related to the script loading. Your script gets loaded after the DOM is processed so function doesn't get attached to the event.
If you are using jQuery then you can use below code.
$(function () {
$("#play_slide").mouseover(function(){
var playTime = 33;
clearTimeout(playTime);
});
});
If you don't want to use JQuery then you can do the same thing in JavaScript as below.
window.onload = function(){
document.getElementById("play_slide").onmouseover = function(){
var playTime = 33;
clearTimeout(playTime);
};
}

I got it! the div tag was somehow broken, I coded a div around it and gave it the event handlers and a class. That worked, then i simply changed the class to an id and got rid of the original div. Idk what was going on but it works now. Thanks for your suggestions!

Can you try this,
<div id="play_slide" onmouseover="StopSlide();">Stop</div>
<script>
var playTime;
var indexPlay;
function playSlide()
{
var slideshow = document.getElementById("play_slide").style;
var images = new Array("an", "complete", "red", "thirteen");
indexPlay++;
if(indexPlay > images.length - 1)
{
indexPlay = 0;
}
slideshow.backgroundImage = "url('assets/images/play/"+images[indexPlay]+".png')";
playTime = setTimeout("playSlide()", 2500);
}
function StopSlide(){
window.clearTimeout(playTime);
}
playSlide();
</script>

jQuery Show/Hide divs one at a time

I have slightly modified the code in this post jQuery div content partial hide, show all to show/hide a list of div's on my page.
I am still learning jQuery and am trying to figure out how I can modify the code so that when I open one div, it will close any other's that are open.
Thanks a lot for any help. Here is my code block:
function setScroll(){
var slideHeight = 80;
$(".container").each(function() {
var $this = $(this);
var $wrap = $this.children(".wrap");
var defHeight = $wrap.height();
if (defHeight >= slideHeight) {
var $readMore = $this.find(".heading");
$wrap.css("height", slideHeight + "px");
$readMore.append("<div id='clickButton' class='expand-div'>Click for More Info</div>");
$readMore.children("#clickButton").bind("click", function(event) {
var curHeight = $wrap.height();
if (curHeight == slideHeight) {
$wrap.animate({
height: defHeight
}, "normal");
$(this).removeClass("expand-div").addClass("collapse-div");
$(this).text("Close");
$wrap.children(".gradient").fadeOut();
} else {
$wrap.animate({
height: slideHeight
}, "normal");
$(this).removeClass("collapse-div").addClass("expand-div");
$(this).text("Click for More Info");
$wrap.children(".gradient").fadeIn();
}
return false;
});
}
});
}

Simple example (jsfiddle) demonstrates closing all and opening one.
var divs = $('div.highlander').hide();
var which = divs.length;
$('#cycler').click(function () {
which += 1;
if (which >= divs.length) {
which = 0;
}
divs.hide();
divs.eq(which).show();
});

Roy's answer is good. I have another example of something you could do. A little bit more general and possible easier to understand. http://jsfiddle.net/sFR6Q/2/
<button class="show1">show1</button>
<button class="show2">show2</button>
<button class="show3">show3</button>
<button class="show4">show4</button>
<div class="show1">1</div>
<div class="show2">2</div>
<div class="show3">3</div>
<div class="show4">4</div>
var divs = $("div")
$('button').click(function () {
divs.hide();
$("div." + $(this).attr("class")).show();
});

First close all the div's irrespective of if they are open or closed.
Then just open the div you need.

Getting the next image and previous image from an gallery

I am trying to code my own image gallery using html css jquery. I have a modal window to show the clicked in images. Inside my modal window I have a previous and next button.
My question is how can i show the previous images or next images when someone click that button.
Here's my jsFiddle
jquery code i am using to show clicked in images.
$(function(){
$('.gallery a').click(function(evt) {
evt.preventDefault( );
var imgPath = $(this).attr('href');
$('.gallery-overlay').show()
.find('.gallery-image').attr('src',imgPath);
return false;
});
});

Add this to your jQuery.
Declare a variable current image in your function and keep current image saved in that variable. Update the variable whenever current image is changed.
Updated jsfiddle
Click on the second image in the images and see the prev and next image then.
$('.gallery-control-previous').click(function(){
var imgPath = current_img.prev().attr('href');
current_img = current_img.prev();
$('.gallery-overlay').show().find('.gallery-image').attr('src',imgPath);
});
$('.gallery-control-next').click(function(){
var imgPath = current_img.next().attr('href');
current_img = current_img.next();
$('.gallery-overlay').show().find('.gallery-image').attr('src',imgPath);
});
If you have understood this answer, add checks to the code showing next, prev elemments only when they exist.
You can find how to do that,
here..
Updated.
Get the first child of next row, and pass that.
$('.gallery-control-next').click(function(){
if(current_img.next().length){
current_img = current_img.next();
}else{
current_img = current_img.parents(".row").next(".row").find("a:first");
}
var imgPath = current_img.attr('href');
$('.gallery-overlay').show().find('.gallery-image').attr('src',imgPath);
});

I have added img_no to each a tag to identify the current active image and get next or previous image
Working Demo
$(function () {
$('.gallery a').click(function (evt) {
evt.preventDefault();
var imgPath = $(this).attr('href');
var img_no = $(this).attr('img_no');
$('.gallery-overlay').show()
.find('.gallery-image').attr('src', imgPath).attr('img_no', img_no);
return false;
});
});
i = 1;
$('.row a img').each(function () {
$(this).attr('img_no', i);
$(this).parents('a').attr('img_no', i);
i++;
});
images_length = i - 1;
console.log(images_length);
$('.gallery-control-next').click(function () {
var img_no = $(this).parent().parent().find('.gallery-image').attr('img_no');
img_no++;
if (img_no > images_length) {
img_no = 1;
}
$('.row a').each(function () {
if ($(this).attr('img_no') == img_no) {
imgPath = $(this).attr('href');
}
});
$('.gallery-imagebox img').attr('src', imgPath).attr('img_no', img_no);
});
$('.gallery-control-previous').click(function(){
var img_no = $(this).parent().parent().find('.gallery-image').attr('img_no');
img_no--;
if (img_no <= 0) {
img_no = images_length;
}
$('.row a').each(function () {
if ($(this).attr('img_no') == img_no) {
imgPath = $(this).attr('href');
}
});
$('.gallery-imagebox img').attr('src', imgPath).attr('img_no', img_no);
});

javascript Remove value from array, array problems

I am trying to fill an array with strings, the elements that will be added are the HTML of the clicked <\li>, im probably filling it correctly.
My problem is when the user clicks on the checked link again, i want to remove this item from the array
Here is a code sample:
$(document).ready(function(){
var chosen = [];
var chosenCounter = 0;
find("ul").find("li").click(function(){
var checkBox = $(this).find("img").first();
var checkBoxSrc = checkBox.attr("src");
if(checkBoxSrc == "images/unchecked.png"){
checkBoxSrc = "images/checked.png";
checkBox.attr("src",checkBoxSrc);
checkBox = "";
checkBoxSrc = "";
var temp = this.outerHTML;
chosen[chosenCounter] = temp;
chosenCounter ++;
}
if(checkBoxSrc == "images/checked.png"){
checkBoxSrc = "images/unchecked.png";
checkBox.attr("src",checkBoxSrc);
checkBox = "";
checkBoxSrc = "";
for (var j =0; j<=chosen.length; j++){
var tempRemove = this.outerHTML;
chosen.splice( chosen.indexOf( tempRemove ), 1 );
tempRemove = '';
}
}
});
});
I have been trying all functions and ways i found on internet .. but the results doesn't works well, i would be very thankful for a correction and explanation.
Thanks all in advance.

I've gone through an rewritten the code to work much better. There were a number of issues but here is the fixed version that I tested.
Your original code had an if statement and then another if statement. You needed an if and then an else if.
Notice when finding the child element I just use $('img', this) instead of the find operator and first().
Use ID instead of HTML
For debugging there is a console.log statement in there. Remove this so it works in IE.
To add an element to an array use push
No need to loop over splice to remove the item. Just call splice once.
$(document).ready(function () {
var chosenIDs = [];
$("ul li").click(function () {
var checkBox = $('img', this);
var checkBoxSrc = checkBox.attr("src");
var id = $(this).attr('data-id');
console.log(id + ' ' + chosenIDs.length + ' ' + checkBoxSrc);
if (checkBoxSrc == "images/unchecked.png") {
checkBoxSrc = "images/checked.png";
checkBox.attr("src", checkBoxSrc);
chosenIDs.push(id);
}
else if (checkBoxSrc == "images/checked.png") {
checkBoxSrc = "images/unchecked.png";
checkBox.attr("src", checkBoxSrc);
chosenIDs.splice(chosenIDs.indexOf(id), 1);
}
});
});

get id of child element when parent is clicked

Hello I have seen similar posts but none answer what I want to accomplish
I made a sample here
http://jsfiddle.net/edgardo400/R6rVJ/
What i basically want is when a click happens in the parent you get the id of the child
and store it in a variable so i can pass the variable currentID to the code below otherwise I will have to replicate this code 9 times for each id from box1 to box9
jQuery(currentID).delegate("a", "hover", function(event){
var $img = jQuery(this).parent("li").find('img');
var image = jQuery(this).attr('data-img');
jQuery('.defaultimg').stop(true, true).fadeOut();
if( event.type === 'mouseenter' ) {
if($img.length){
$img.show();
}else{
jQuery(this).parent("li").append('<img id="theImg" src="' + image + '" />');
}
}else{
if($img){
$img.hide();
}
jQuery('.defaultimg').stop(true, true).fadeIn();
}
});
});

$('#boxes').on('click', function(e) {
var currentID = e.target.id;
console.log(currentID);
......rest of code

In javascript it would be:
var a = document.getElementById('#boxes');
a.onclick = function(e){
console.log(e.target.id);
}

If you only wish to make your code working and displaying on your console the box name, you should probably set
jQuery('#boxes').bind('click', function(event) {
var currentID = jQuery(event.srcElement).attr('id');
/* rest of your code */
});
You might want to do something easier
jQuery('#boxes').children().bind('click', function() {
jQuery(this).delegate...
});
Although I'm not sure why you are doing this ...
