Remove an image when mouse leaves a div - javascript

I have a 3X3 box and currently I have it so that when you hover over any one of the squares the background turns blue and then when you hover out the box reverts back to empty. I also have it so that when any of the boxes are clicked an image appears. What I am trying to accomplish now is to make it so that when the box is clicked the image will appear and when that same box is clicked again the image will disappear and so on using Jquery.
Here is what I have:
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
<script type="text/javascript">
$(function () {
$('.divs').hover(function () {
$(this).css("background-color", "#0000EE");
console.log('hover');
}, function () {
$(this).css("background-color", "");
console.log('hoverout');
});
$('.divs').click(function () {
$(this).prepend("<img class='divimg' src=http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/SMirC-cool.svg/320px-SMirC-cool.svg.png>");
console.log('divclicked');
});
});

Just check if there is an image there already
var $img = $("img", this);
if ($img.length > 0)
$img.remove();
else
$(this).prepend("<img class='divimg' src=http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/SMirC-cool.svg/320px-SMirC-cool.svg.png>");
If you don't want to remove the image, you just toggle the visibility
var $img = $("img", this);
if ($img.length > 0) {
$img.toggle();
} else {
$(this).prepend("<img class='divimg' src=http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/SMirC-cool.svg/320px-SMirC-cool.svg.png>");
}

Have you tried jQuery().hide() and jQuery().show()

The other option is to use CSS :hover attribute.
.divs:hover {
background-color: #0000ee;
}
Regarding click you can add images to your divs and use jQuery toggling.
HTML:
<div class="divs"><img src="..." alt=""></div>
JavaScript:
$('.divs').click(function () {
$(this).children("img").toggle();
});

Try the following code in you click function
if($('img.divimg').length == 0){
$('img.divimg').fadeOut(function(){
$(this).remove()
});
}else{
$(this).prepend("<img class='divimg' style='display:none;' src=http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/SMirC-cool.svg/320px-SMirC-cool.svg.png>").fadeIn();
}
Another option is to make the remove action on the added image (when it is clicked).
var img = $('<img>')
.attr('src', 'http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/SMirC-cool.svg/320px-SMirC-cool.svg.png')
.addClass('divimg')
.css('display', 'none')
.bind('click', function(){
$(this).remove();
});
$(this).prepend(img);

jquery swap image on element click not functioning

I am trying to swap an image on click with jquery. I have got it to work with the click being bound to the image class. However, if I try and wrap the function and bind the event to a button or anchor, it will not swap the images. Here is the jquery:
<script type="text/javascript">
jQuery(document).ready(function( $ ) {
$(".test_toggle").click(function(){
$(this).find(".img-swap").live('click', function() {
if ($(this).attr("class") == "img-swap") {
this.src = this.src.replace("_off","_on");
} else {
this.src = this.src.replace("_on","_off");
}
$(this).toggleClass("on");
});
});
});
</script>
This worked:
jQuery(document).ready(function( $ ) {
$(".img-swap").live('click', function() {
if ($(this).attr("class") == "img-swap") {
this.src = this.src.replace("_off","_on");
} else {
this.src = this.src.replace("_on","_off");
}
$(this).toggleClass("on");
});
});
Any help is greatly appreciated.
I don't think there's any need to delegate the event listeners so I've removed them. Simply add the click event to the image and then you can manually 'trigger' a click on it when the .test-toggle is clicked. E.G:
$(function() {
//add on click event
$(".img-swap").on('click', function() {
if (this.src.indexOf("_off")>0) {
this.src = this.src.replace("_off","_on");
} else {
this.src = this.src.replace("_on","_off");
}
});
//add remote trigger
$(".test_toggle").on('click', function(){
$(".img-swap").trigger("click");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img class="img-swap" src="https://placehold.it/300?text=_off" />
<button class="test_toggle">test toggle</button>
Thats because unlike like img.
a or button doesn't have a src attribute.
So when you bind the event to a button or anchor, this.src in your second instance of the code will be invalid.
I would delete this line:
$(this).find(".img-swap").live('click', function() {
What is it's purpose? You can swap this image right after the first click, right?
Also, make sure that .img-swap is inside the tag with class test_toggle.
You are using:
$(this).find(".img-swap")
find() searches only in children of selected element.
If it's not nested use
$(".img-swap")
instead of:
$(this).find(".img-swap")
I have re-written the js, but not tested. Can I nest clicks?
$(".test_toggle").click(function(){
$.find(".img-swap").click(function(){
if ($(this).attr("class") == "img-swap") {
this.src = this.src.replace("_off","_on");
} else {
this.src = this.src.replace("_on","_off");
}
$(this).toggleClass("on");
});
});

Remove from inside div using jQuery

I have written a script that is supposed to render text (later a partial view) inside a div on click. I detect if div is visible or not and if not, I add text on click and make the div visible. This part works perfectly. When clicked and the div is visible I want to remove what has been added so that it wont multiply if I click it multiple times.
I get both alert - so detection of div visibility works but the text is not removed and it multiplies if I click it many times.
Here is my code - can you tell me what i am doing wrong?
<script language="javascript">
$(document).ready(function () {
$(".content").hide();
$(".heading").click(function () {
var id = $(this).attr("id");
var content = $(this).next(".content");
if (content.is(":hidden")) {
content.append("<p id='render-object'>Testing rendering on click</p>");
alert('Content is opening');
}
else if (content.is(":visible")) {
content.next("#render-object").remove();
alert('Content is closing');
}
content.slideToggle(100);
});
});
</script>
You probably want to use .find() instead of .next() when removing.
Use .html() instead of .append()
<script language="javascript">
$(document).ready(function () {
$(".content").hide();
$(".heading").click(function () {
var id = $(this).attr("id");
var content = $(this).next(".content");
if (content.is(":hidden")) {
content.html("<p id='render-object'>Testing rendering on click</p>");
alert('Content is opening');
}
else if (content.is(":visible")) {
content.find("#render-object").remove();
alert('Content is closing');
}
content.slideToggle(100);
});
});
</script>
Edit : - use .find() instead of .next() as render-object is child of content and not sibling
use .find instead of .next and use .html instead of .append
<script language="javascript">
$(document).ready(function () {
$(".content").hide();
$(".heading").click(function () {
var id = $(this).attr("id");
var content = $(".content");
if (content.is(":hidden")) {
content.html("<p id='render-object'>Testing rendering on click</p>");
alert('Content is opening');
}
else if (content.is(":visible")) {
content.find("#render-object").remove();
alert('Content is closing');
}
content.slideToggle(100);
});
});
</script>

text show when hover img1 - hide only when hover img2

Have something like:
<div id="Oobj51">
<script type='text/javascript'>
$(function() {
$('#Oobj51').hover(function() {
$("#Oobj58").show(500);
}),
$("#Oobj58").hover(function() {
//do nothing if hovered over
},
function(){
//hide on hover out
$("#Oobj58").hide(500);
});
});
</script>
<button type="submit" class="przed" onmouseover="this.className='po'" onmouseout="this.className='przed'"/>
</div>
Then I have 7 images like "Oobj51" and to each one of them there's a part of form in this case "Oobj58".
How to make the Oobj58 disaapear not when hover out but when hover on next img "Oobj52" where next part of form "Oobj59" should appear.??
First give every div the same class name:
<div class="Oobj" id="Oobj51">
Then use the id of the hovered div to define what to do next:
$(function() {
$('.Oobj').hover(function() {
var currentId = $(this).attr('id');
if(currentId == 'Oobj51') {
$("#Oobj58").show();
$("#Oobj59").hide();
} else if(currentId == 'Oobj52') {
$("#Oobj58").hide();
$("#Oobj59").show();
}
});
});
You could take a look at mouseenter event (doc http://api.jquery.com/mouseenter/)
$("#Oobj51").mouseenter(function()
{
$("#Oobj58").show();
})
$("#Oobj51").mouseleave(function()
{
$("#Oobj58").hide();
});

a second click to close a toggle div

I’m using the following jQuery for hiding and showing content (toggle), as a tree navigation menu in my website. I found this code extremely useful because by clicking, it displays only one div at a time.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
function show_region(chosen_region) {
$('.city_div').each(function(index) {
if ($(this).attr("id") == chosen_region) {
$(this).slideDown(200);
}
else {
$(this).slideUp(600);
}
});
}
</script>
<style type="text/css">
.city_div {display: none;}
</style>
North<br>
<div class="city_div" id="box01">Div #01</div>
Centre<br>
<div class="city_div" id="box02">Div #02</div>
South<br>
<div class="city_div" id="box03">Div #03</div>
The problem is that I can close a div only by opening another div.
How to close the div by a second click on it?
You can use slideToggle, change from slideDown to slideToggle:
function show_region(chosen_region) {
$('.city_div').each(function(index) {
if ($(this).attr("id") == chosen_region) {
$(this).slideToggle(200); // instead of slideDown
}
else {
$(this).slideUp(600);
}
});
}
First of all, don't use inline event handlers.
<script type="text/javascript">
$(document).ready(function() {
var boxes = $('.city_div');
$('.city-toggle').click(function(e) {
var box = $(this).next();
var isHidden = box.is(':hidden');
boxes.slideUp(600);
if(isHidden) {
box.slideDown(200);
}
e.preventDefault();
});
});
</script>
<style type="text/css">
.city_div {display: none;}
</style>
North
<div class="city_div" id="box01">Div #01</div>
Centre
<div class="city_div" id="box02">Div #02</div>
South
<div class="city_div" id="box03">Div #03</div>
Also, if your links don't go anywhere meaningful, use # as the href and make sure the boxes are visible by default. (Hide them using boxes.hide(); right at the start.)
Also also, <br> isn't what you should use there. <div>s are already block-level elements. If you want more padding, give them a top margin.
try this:
$(document).ready(function(){
$('.city_div').click(function(){
$(this).hide(); //or whatever code you want to hide it
});
});
that way when you click on a div, it will hide it.
Since you are using jQuery you could try using the jQuery.toggle function.
function show_region(chosen_region) {
$('#' + chosen_region).toggle('slide');
return false;
}
Keep track of the div you have clicked last:
var globalLastClickedButtonId;
$("div.city_div").click(function() {
if (globalLastClickedButtonId == $(this).attr("id")) {
$(this).hide();
} else {
var box = $(this).next().next();
var clickedId = $(this).attr("id");
$("div.city_div").each(function() {
if ($(this).attr("id") == clickedId)
box.slideDown(200);
else
box.slideUp(600);
}
}
globalLastClickedButtonId = $(this).attr("id");
});
First, why are you using such an old version of jQuery?
Second, your JavaScript can be simplified. jQuery works on sets; you don't need the .each, or loops.
Here is a working example: http://jsfiddle.net/gibble/25P9z/
Simplified HTML:
North<br>
<div class="city_div" id="box01">Div #01</div>
Centre<br>
<div class="city_div" id="box02">Div #02</div>
South<br>
<div class="city_div" id="box03">Div #03</div>​
New JavaScript:
function show_region(e) {
var $target = $(e.target);
var chosen_region = $target.attr('data-contentDiv');
var openDiv = $('#' + chosen_region);
openDiv.slideDown(200);
$('.city_div').not(openDiv).slideUp(600);
}
Last, attach events, don't inline them in your HTML.
$('a[data-contentDiv]').click(show_region);​
Because you are using an animation it is best to keep track of the div that is currently shown. If you don't, then you will start to see multiple divs showing if you click links in quick succession.
You can use this:
$(function() {
$("a").click(function(e) {
e.preventDefault();
var selectedDiv = $("#" + $(this).attr("href"));
var hide = selectedDiv.data("shown");
$(".city_div").slideUp(600);
$(".city_div").data("shown", false);
if (hide) {
selectedDiv.data("shown", false);
}
else {
selectedDiv.data("shown", true);
selectedDiv.slideDown(200);
}
});
});​
Here is a working example
You should keep a variable with your old chosen region name
<script type="text/javascript">
var old_chosen_region="";
function show_region(chosen_region) {
$('.city_div').each(function(index) {
if (($(this).attr("id") == chosen_region)&&(chosen_region!=old_chosen_region)) {
$(this).slideDown(200);
old_chosen_region=chosen_region;
} else {
$(this).slideUp(600);
}
}
old_chosen_region='';
});
</script>
This allows you to 'remember' which region you chose last and, if the chosen one equals the last you close it.
You should set old_chosen_region='' in the end to let the tab reopen.

Toggle element's class by ID

I’m trying to change the class of an element when it is clicked on from one value A to value B and then from value B back to value A when it is clicked a second time. I found some code on here that allowed me to change it once, but not a second time. (See original here).
Here is the original code:
<script type="text/javascript">
function changeClass() {
document.getElementById("MyElement").className += " MyClass";
document.getElementById("MyElement").className = document.getElementById("MyElement").className.replace(/(?:^|\s)MyClass(?!\S)/g, '')
}
</script>
And here is my code:
<script type="text/javascript">
function changeClass() {
if (document.getElementByID("arrow").className == "arrowdown") {
document.getElementById("arrow").className.replace(/(?:^|\s)arrowdown(?!\S)/g, 'arrowup')
}
elseif(document.getElementByID("arrow").className == "arrowup") {
document.getElementById("arrow").className.replace(/(?:^|\s)arrowup(?!\S)/g, 'arrowdown')
}
}
</script>
$('#arrow').toggleClass('arrowup arrowdown');
Why not simply use jQuery toggleClass instead along with a id selector?
$('#arrow').toggleClass('arrowup');
$('#arrow').toggleClass('arrowdown');
And save yourself debugging and a few lines of code!
Check this FIDDLE
Its far easier with JQuery..
$(function() {
var i = 0;
$('div').on('click', function() {
i++;
if( i % 2 == 0){
$(this).addClass('arrowup').removeClass('arrowdown');
}
else{
$(this).addClass('arrowdown').removeClass('arrowup');
}
});
});​
just use jquery addClass() and removeClass() or even better the toggleClass inside your click event
<div id="elemID" class="class1">
</div>
function changeClass()
{
$("#elemID").toggleClass("class1");
$("#elemID").toggleClass("class2");
}

I faced something similar to this today. In my code for each feature the user would express his opinion by pressing thumbs up or thumbs down. The selected thumb icon would have a brighter color, so when the user would click the thumbs up icon, the thumbs up icon would turn green and the thumbs down icon (if it were green) would turn black.
I solved it using jQuery:
$(document).ready(function () {
$('#vote-yes-#(Model.ProductReviewId)').click(function () {
setProductReviewHelpfulness#(Model.ProductReviewId)('true');
$('#1vote-yes-#(Model.ProductReviewId)').toggleClass('green');
$('#1vote-no-#(Model.ProductReviewId)').removeClass('green').addClass('black');
});
$('#vote-no-#(Model.ProductReviewId)').click(function () {
setProductReviewHelpfulness#(Model.ProductReviewId)('false');
$('#1vote-no-#(Model.ProductReviewId)').toggleClass('green');
$('#1vote-yes-#(Model.ProductReviewId)').removeClass('green').addClass('black');
});
});
