Remove from inside div using jQuery - javascript

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>

Making div invisible and visible using toggle in jQuery

I have a div where when you click it, it's suppose to turn invisible, and when you click on it again, it's suppose to turn visible. But something's wrong with my code. Please take a look:
<div id = "id"> Hello </div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script type = "text/javascript">
//*****************************************************************************
function toggleOnClick($id){
$("#"+$id).click(function() {
$("#"+$id).toggle(
function () {
$(this).css({visibility: "hidden"});
},
function () {
$(this).css({visibility: "visible"});
}); //end of $("#"+$id).toggle
}); //end of $("#"+$id).click(function()
} //end of function toggleOnclick($id)
//*****************************************************************************
$(document).ready(function(){
toggleOnClick("id");
});
</script>
P.S: Got my source from the accepted answer in this link: jQuery toggle CSS?
tggle() will toggle between display property so it will not retain place for element after it hides, You need to use css() with callback and update its opacity, it will retain it's place.
Update : The click event will not fire on element with visibility: hidden so you need to use opacity:0
Callback in css() is a function returning the value to set. this is the current element. Receives the index position of the element in the set and the old value as arguments. ( Taken from http://api.jquery.com/css/#css-propertyName-function )
<div id="id">Hello</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script type="text/javascript">
//*****************************************************************************
function toggleOnClick($id) {
$("#" + $id).click(function() {
$("#" + $id).css('opacity', function(i, v) {
return v == 0 ? 1 : 0; //end of $("#"+$id).toggle
});
}); //end of $("#"+$id).click(function()
} //end of function toggleOnclick($id)
//*****************************************************************************
$(document).ready(function() {
toggleOnClick("id");
});

On click add/remove overflow hidden

I'm trying to add/remove .css('overflow-y','hidden') onclick, Which I did. The problem appears when I try to remove that css, also onclick. But this time, user needs to click on another element.
Idea is to have modal (twitter bootstrap 2.3) window where there is some data and when user click on modal button (triggers) the css applies to html element in order to prevent scrolling of the website. And now when I click anywhere on modal (modal shuts down) but there is still overflow-y styling and because of it I can't scroll my page.
So this is what I've made, but I have been stuck here and don't know where I am making mistake. Could anyone help me with this one, and if is possible give me some advice so I could take care in future.
Thanks!
<script type="text/javascript">
$('#myModal').modal('hide') // initializes and invokes show immediately</p>
$('.note').delay(10000).fadeOut('slow');
$(document).ready(function() {
var $html = $('html');
var $button = $('.container > .btn-primary');
var $modal = $('.modal-backdrop');
$button.on('click', function(e) {
$html.css('overflow-y', 'hidden');
if ($html.attr('style')) {
alert('WORKS!');
}
else {
$modal.onclick( function() {
$html.css('overflow-y','scroll');
});
};
});
});
</script>
Put your css in a class and use jquery's .toggleClass() to show/hide the overflow.
Here's a simplified example: http://jsbin.com/towiyaqa/1/
You can use like this:
$button.on('click', function(e) {
$html.css('overflow-y','hidden' ? 'scroll' : 'hidden');
e.preventDefault();
})
Here is solution for problem:
$(document).ready(function() {
var $html = $('html');
var $button = $('.container > .btn-primary');
var $modal = $('.modal-backdrop');
$button.on('click', function(e) {
$('.note').delay(10000).fadeOut('slow');
$html.css('overflow-y', 'hidden');
if ($html.attr('style')) {
console.log("overflow-y: hidden added");
}
});
$('#myModal').on('hidden.bs.modal', function () {
// do something…
console.log("fires myModal");
$html.css('overflow-y','scroll');
});
});
</script>

Remove dynamically generated div with jquery

I would like to add/remove a new div when the corresponding checkbox is checked/unchecked with jQuery. Here's my attempt:
<script type="text/javascript">
$(function() {
$("#form1 :checkbox#checkbox1").click(function() {
var d = document.createElement('div');
if ($(this).is(":checked")) {
$(d).addClass("newdiv")
.html("This is a new div")
.appendTo($("#mydiv"))
.hide()
.fadeIn(1000);
}
else {
//$(".newdiv").fadeOut(1000);
$(d).fadeOut(1000);
}
});
});
</script>
The fadeIn process comes out smoothly. But when I tried to fadeOut $(d) using the same methodology, it didn't work: the new generated div remained on the page. I did some research and get a work around, with $(".newdiv").fadeOut(1000); (commented in the code above), but that's not the best solution for me I think. And also I really want to know why my first attempt didn't work. Any suggestions? Thanks.
There are few changes you can make
1. No need for the selector #form1 :checkbox#checkbox1 since you have an id for the checkbox, you can just use #checkbox1
2. Create the div using jQuery instead of using createElement $('<div/>')
3. After fading out the div you need to remove it from the dom
$(function() {
$("#checkbox1").click(function() {
if ($(this).is(":checked")) {
$('<div/>').addClass("newdiv")
.html("This is a new div")
.appendTo($("#mydiv"))
.hide()
.fadeIn(1000);
}
else {
$('#mydiv .newdiv').fadeOut(function(){
$(this).remove()
})
}
});
});
Demo: Fiddle
Another solution is to have a static div which will be shown and hidden
$(function() {
var div = $('<div/>').addClass("newdiv")
.html("This is a new div")
.appendTo($("#mydiv"))
.hide();
$("#checkbox1").click(function() {
if ($(this).is(":checked")) {
div.fadeIn(1000);
} else {
div.fadeOut(1000)
}
});
});

Every time your click handler runs, you're creating a new variable d with a new element. Instead, do that before the click handler, so each instance will reference the same element. I have included other optional improvements below.
A change event is more appropriate for checkboxes. Also, notice I made your selector just #checkbox1, since that is already unambiguous and maximally specific.
To get a better visual effect, don't add the element, hide it, then fade it in. In most browsers that will show the element flicker before it appears. Instead, use a class to hide it with css: .hidden {display: none;}. You can also use fadeToggle to toggle the visibility, instead of doing if/else. clearQueue removes extra events for multiple clicks during a transition, and makes transitions appear smoother.
Finally, use jQuery to create the element:
$(function () {
var $d = $('<div>', {
"class": "hidden",
text: "This is a new div"
}).appendTo("#mydiv");
$("#checkbox1").change(function () {
$d.clearQueue()
.stop()
.fadeToggle(1000);
});
});
You better make d a jQuery object.
<script type="text/javascript">
$(function() {
$("#checkbox1").click(function() {
var d = $('<div class="newdiv"></div>');
if ($(this).is(":checked")) {
d.html("This is a new div")
.appendTo($("#mydiv"))
.hide()
.fadeIn(1000);
}
else {
d.fadeOut(1000);
}
});
});
</script>

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.

Jquery toggle background color

I have a jquery function that when a li is clicked, the li expands. That part is working fine. Now, I want, when the li is clicked it toggles a background color. But it works, however when i have to click on the li item again to untoggle the background color. Can someone assist me in the right direction on how to achieve this.
$(function() {
$('.a').click(function() {
var name = $(this).attr("name");
var content = $('.content[name=' + name + ']');
$('.content').not(content).hide('fast');
$('.selected').css('background', 'yellow');
content.slideToggle('fast');
});
$("li").click(function() {
$(this).toggleClass("highlight");
});
});​
On every click set your <li>-s to default color and highlight the current:
$("li").click(function() {
$("li").removeClass("highlight");
$(this).addClass("highlight");
});
...
UPDATE
http://jsfiddle.net/NXVhE/4/
$(function() {
$('.a').click(function() {
$(this).removeClass("highlight");
var name = $(this).attr("name");
var content = $('.content[name=' + name + ']');
$('.content').not(content).hide();
content.toggle();
});
$("a").click(function () {
$("a").removeClass("highlight");
if ( $(".content").is(":visible") ) {
$(this).addClass("highlight");
}
});
});
Assuming the <li>s are all siblings, it would be slightly more efficient to do something like this, and would allow for more than one list on the same page to function independently of one another (again, assuming that is the desired functionality)
$('li').click(function() {
$('this').addClass('highlight').siblings().removeClass('highlight').
});
