Events in javascript

I want to open a form on click of modify. I also want form to disappear when i click outside the form. When i use mouseleave event for that, the form is getting open and close automatically and i am failing to fill the form. I am not getting which event to use here.
JS
$(document).ready(function() {
$("#div1").load("compare-form-site.html");
});
$( ".m-search" ).click(function() {
$( "#modify" ).show( "blind",700 );
$( "#bank" ).hide();
$( ".slider" ).hide();
$( "#type" ).hide();
$( "#sort" ).hide();
});
$(".m-search").mouseleave(function(){
$('#modify').hide( );
});
HTML
<ul>
<li class="m-search">
Modify Search
<i class="fa fa-search-plus" aria-hidden="true">
</i>
<div id="modify" class="modify">
<div id="div1">
</div>
</div>
</li>
</ul>

You can compare to the target element and check if you click outside the form or in it. I f outside then hide the form.
$(document).on('click', function(e){
var $target = $('.modify');
if($target.is($(e.target)) && !$trigger.has(e.target).length) {
$('.modify').hide();
}
})

A working fiddle would be better for all to help you.
Here is an working example that should be help you:
// open the form
$('.modify').on('click', function(e) {
$(this).parent().find('.dialog').fadeIn();
});
// close the form (button inside form)
$('.close').on('click', function(e) {
$(this).parents('.dialog').fadeOut();
});
// hide the form if you click outside the form
$(document).mouseup(function (e) {
var container = $(".dialog");
if (!container.is(e.target) && container.has(e.target).length === 0) {
container.hide();
}
});
ul li button {
display: block;
}
.dialog {
display: none;
position: absolute;
top: 10%;
bottom: 10%;
left: 10%;
right: 10%;
background: blue;
}
.dialog .close {
float: right;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>
Modifiy Search
<button class="modify">Test</button>
<div class="dialog">
<span class="close">Close me</span>
Im a test dialog
</div>
</li>
</ul>

mouseleave doesn't react on click but on the current pointer position. You have to add a click (mousedown) listener to e.g. document to listen to click events outside

Reorder Divs Vertically using Jquery Issue

I'm asking as a last resort before I tear the last of my hair out. At the moment I am showing an initial 2 divs. The user can then add these two divs below the original as many times as they want. They can also remove the 2 divs if necessary. I am trying to allow reording of the divs using drage and drop. I've tried numerous methods but I just can't get it working. As an extra note, the divs need to reindex themselves once the user has dragged and dropped. Here is the code that I have. Please take into consideration that I have added and deleted lots of code attempts before settling on this basic implementation. Thanks in advance.
Load JQuery
Display first div to end user
<!--Div contains each answer step-->
<div id = "answer_step" class = "answer_step">
<!--This placeholder text is styled from CSS and will empty the div once the user starts typing-->
<div id="answer_step_equation0" class="answer_step_equation" contenteditable="true" placeholder="Enter The Next Solution Step This Question"></div>
<div id="answer_step_description0" class = "answer_step_description" contenteditable="true" placeholder="Enter A Description as to how this step was reached or how to solve the next step"></div>
</div>
</div>
<!-- Buttons to dynamically add and remove answer divs. The remove functionality is added in JQuery for the add button-->
<button id="add_answer_step_button" class="add_answer_step_button">+ Add next Step</button>
This code appends the new divs. I have to put the three divs within a div like above but I can't get it to work.
<!--Script to append/remove div when user clicks on add_answer_step_button-->
<script type = "text/javascript" language = "javascript">
$(document).ready(function() {
<!--This variable gives each new set of answer divs a unique id by appending a number to the end of th id-->
<!--The first set of answer divs will have an id of zero-->
var answer_identifier_number = 1;
$("button.add_answer_step_button").click(function () {
$("div.answer_steps").append('<div id="answer_step_equation' + answer_identifier_number + '" class="answer_step_equation" contenteditable="true" placeholder="Enter The Next Solution Step This Question"></div>');
$("div.answer_steps").append('<div id="answer_step_description' + answer_identifier_number + '" class = "answer_step_description" contenteditable="true" placeholder="Enter A Description as to how this step was reached or how to solve the next step"></div>');
$("div.answer_steps").append('<button id="remove_answer_step_button' + answer_identifier_number + '" class = "remove_answer_step_button">- Remove This Step</button>');
answer_identifier_number++;
});
});
</script>
Allow the divs to be draggable
<script type = "text/javascript" language = "javascript">
$(function() {
$( "#answer_steps" ).sortable();
$( "#answer_steps" ).disableSelection();
cursor: move;
});
</script>
I haven't figured out how to reindex the names yet but I have experience of that part so I should be fine. Thanks for your help.

ok, before you go tearing your hair out, have a look at this 'drag and drop' fiddle - its a heres-one-I made-earlier one jsfiddle.net/RachGal/ahnx7kwc It'll give you an idea about how the whole drag and drop thing works – Rachel Gallen 2 days ago

Simplify this javascript for Show one, Hide Rest

I am using a script for a gallery in which clicking on an element in the navigation shows only one div, but hides the others.
Currently my script is very specific, as I need to add a new function for every possible instance. See below... You can imagine this grows out of control easily the more images are added.
Can someone help me make this code more generic and elegant? I'm not very experienced with Javascript/JQuery but this is getting a bit embarrassing lol
So in case it's not clear from the code: the #li1, #li2, #li3 etc are the navigational thumbnails which are always visible. The #img1, #img2, #img3 etc. are the variable displayed divs. When one is visible, the rest should be hidden.
Additional questions:
for every #img1 displayed, I'd like to also show a title in a separate div, let's say #title1, #title2, etc. How do I do this? So eg clicking #li1 would show #img1 and #title1 but hide all other #img.. and #title..
all #'s contain images. I've noticed that when one of the images is broken, the whole script stops working properly (all #img.. divs show at once). Why is that?
this script doesn't actually hide all the images until everything is loaded, which you don't notice when running the HTML locally, but you do when you're waiting for the images to download. I'm suspecting because the $("#li1").load(function() refers to a div that is further down in the document. How can I counter this?
I hope I'm not asking too much, I've tried to understand this myself but I can't figure it out.
$("#li1").load(function() {
$("#img2, #img3, #img4, #img5, #img6, #img7, #img8, #img9, #img10, #img0, #intro").hide();
$("#img1").show();
});
$("#li1").on('click', function() {
$("#img2, #img3, #img4, #img5, #img6, #img7, #img8, #img9, #img10, #img0").hide();
$("#img1").show();
});
$("#li2").on('click', function() {
$("#img1, #img3, #img4, #img5, #img6, #img7, #img8, #img9, #img10, #img0").hide();
$("#img2").show();
});
$("#li3").on('click', function() {
$("#img2, #img1, #img4, #img5, #img6, #img7, #img8, #img9, #img10, #img0").hide();
$("#img3").show();
});
etc.

I would probably try something like this:
Thumbnails like:
<li class="thumbnail" data-imageId="0">
...thumbnail...
</li>
<li class="thumbnail" data-imageId="1">
...thumbnail...
</li>
<li class="thumbnail" data-imageId="2">
...thumbnail...
</li>
Images like:
<div class="image" data-imageId="0">
...image...
</div>
<div class="image" data-imageId="1" style="display: none;">
...image...
</div>
<div class="image" data-imageId="2" style="display: none;">
...image...
</div>
<!-- The style attribute in these element hides the element by default,
while still allowing jQuery to show them using show(). -->
And then the JS:
$(".thumbnail").click(function() {
// Hides all images.
$(".image").hide();
// Shows appropriate one.
var imageId = $(this).data("imageId"); // Fetches the value of the data-imageId attribute.
$(".image[data-imageId="+imageId+"]").show();
});

I see that your li's have ids of 'li1', 'li2', etc. Assign them all a specific class, like 'liLinks'.
Then, add an event handler for that class like this:
$(".liLinks").click(function(){
var ImageToShow = $(this).prop("id").replace("li", ""); // This gets the number of the li
for (i=0; i<= 10; i++){ //or however many images you have
if (i != ImageToShow)
$("#img" + i).hide();
else
$("#img" + i).show();
}
});
Oh, and you can show and hide any other elements with the same method used above. Just make sure their naming convention is the same, and you should be all set!

So, I have two solutions for you:
First option: Edit the HTML code to fix this logic:
<li class="nav" data-image="0">0</li>
<li class="nav" data-image="1">2</li>
<li class="nav" data-image="2">3</li>
...
...and so on.
Now the JavaScript code will be pretty short and easy, here it is:
function showOne(e) {
var max = 5, // assuming that there are 5 images, from #img0 to #img4
toShow = e.target.dataset.image;
for (var i=0; i < max; i++) {
if (i == toShow) $('#img'+i).hide();
else $('#img'+i).show();
}
}
$('.nav').bind('click', showOne);
If your logic isn't this one then i suggest you to edit the HTML to fix this logic, which is the easiest way to do what you want.
Second option: I am assuming that you use a logic like this:
#li0 shows #img0
#li1 shows #img1
#li2 shows #img2
...
#liN shows the Nth img of the array
Here's the code then:
function showOne() {
var max = 4, // assuming that there are 5 images, from #img0 to #img4
toShow = this.id.substr(2);
$('#img'+toShow).show();
for (var i=0; i < max; i++) {
if (i != toShow) $('#img'+i).hide();
}
}
$('#li0, #li1, #li2, #li3, #li4').bind('click', showOne);
In this snippet I only used 5 images, but you can add more images changing the max value and adding the relative li elements in the $('#li0, #li1, ...) selector.

Just hide all of them with CSS, then override the one you care about to show.

#showbox.show4 img#img4 { display: block; }

</body>
</html>

Your images is not hidden while the images is loading because you didn't use
$(function () {
$("imgs").hide ();
});
This function is excuted when the DOM (HTML) is loaded not the images.
The code will be "HTML":
link1
link2
link3
...
jQuery:
$(function () {
$(".img").hide ();
$(".nav").click (function (e) {
$(".img").show ();
});
});
As you might expect you need to change this code to be more progressive but you now get the idea of making them hidden when the page finish liading not when the images finish downloading. And good luck ;) .

var $img = $('#images img'); /* Cache your selector */
$('#nav li').click(function(){
$img.fadeOut().eq( $(this).index() ).stop().fadeIn();
});
#images{ position:relative; }
#images img{ position:absolute; left:0; }
#images img + img {display:none; } /* hide all but first */
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id=nav>
<li>1</li>
<li>2</li>
<li>3</li>
</ul>
<div id=images>

<img src="//placehold.it/50x50/f0f" alt="">
<img src="//placehold.it/50x50/444" alt="">
</div>

Following is an approach:
Add special classes to identify images.
Use classes to show/hide image like: .showing{display:block;}
Use data attribute to store title like: data-title="title"
Add class to identify li and mark selected li with another class like active
$(function() {
$("li.switch").click(function() {
var liActive = $("li.active");
var imgActive = liActive.data("image");
$(imgActive).removeClass("showing").addClass("hidden");
$(liActive).removeClass("active");
//currently clicked li
var $this = $(this);
$this.addClass("active");
var d = $this.data("image");
$(d).removeClass("hidden").addClass("showing");
$("#imgTitle").text($(d).data("title"));
});
});

Try it in this fiddle

Fix from Ricardo van den Broek's code, because
var imageId = $(this).data("imageId");
is seem doesn't work. It's returns "Undefined". So we need to change it to
var imageId = $(this).attr("data-imageId");
Here is all the code,
HTML (Thumbnail section)
<ul>
<li class="thumbnail" data-imageId="0">
Thumbnail 0
</li>
<li class="thumbnail" data-imageId="1">
Thumbnail 1
</li>
<li class="thumbnail" data-imageId="2">
Thumbnail 2
</li>
</ul>
HTML (Image section)
<div class="image" data-imageId="0">
Image 0
</div>
<div class="image" data-imageId="1" style="display: none;">
Image 1
</div>
<div class="image" data-imageId="2" style="display: none;">
Image 2
</div>
JavaScript (jQuery)
$(".thumbnail").click(function() {
$(".image").hide();
// Shows the appropriate one.
var imageId = $(this).attr("data-imageId");
$(".image[data-imageId="+imageId+"]").show();
});

JQuery show and hide div on mouse click (animate)

This is my HTML code:
<div id="showmenu">Click Here</div>
<div class="menu" style="display: none;">
<ul>
<li>Button1</li>
<li>Button2</li>
<li>Button3</li>
</ul>
</div>
And I want to show .menu on click on #showmenu sliding from left to right (with animate). On click again on #showmenu or anywhere in site page, .menu will hide (slide back to left).
I use JQuery 2.0.3
I've tried this, but it doesn't do what I want.
$(document).ready(function() {
$('#showmenu').toggle(
function() {
$('.menu').slideDown("fast");
},
function() {
$('.menu').slideUp("fast");
}
);
});

That .toggle() method was removed from jQuery in version 1.9. You can do this instead:
$(document).ready(function() {
$('#showmenu').click(function() {
$('.menu').slideToggle("fast");
});
});
Demo: http://jsfiddle.net/APA2S/1/
...but as with the code in your question that would slide up or down. To slide left or right you can do the following:
$(document).ready(function() {
$('#showmenu').click(function() {
$('.menu').toggle("slide");
});
});
Demo: http://jsfiddle.net/APA2S/2/
Noting that this requires jQuery-UI's slide effect, but you added that tag to your question so I assume that is OK.

Of course slideDown and slideUp don't do what you want, you said you want it to be left/right, not top/down.
If your edit to your question adding the jquery-ui tag means you're using jQuery UI, I'd go with nnnnnn's solution, using jQuery UI's slide effect.
If not:
Assuming the menu starts out visible (edit: oops, I see that isn't a valid assumption; see note below), if you want it to slide out to the left and then later slide back in from the left, you could do this: Live Example | Live Source
$(document).ready(function() {
// Hide menu once we know its width
$('#showmenu').click(function() {
var $menu = $('.menu');
if ($menu.is(':visible')) {
// Slide away
$menu.animate({left: -($menu.outerWidth() + 10)}, function() {
$menu.hide();
});
}
else {
// Slide in
$menu.show().animate({left: 0});
}
});
});
You'll need to put position: relative on the menu element.
Note that I replaced your toggle with click, because that form of toggle was removed from jQuery.
If you want the menu to start out hidden, you can adjust the above. You want to know the element's width, basically, when putting it off-page.
This version doesn't care whether the menu is initially-visible or not: Live Copy | Live Source

else {
// Slide in
$menu.show().css("left", -($menu.outerWidth() + 10)).animate({left: 0});
}
});
});
</script>

</html>

I would do something like this
DEMO in JsBin: http://jsbin.com/ofiqur/1/
Click Here
<div class="menu">
<ul>
<li>Button 1</li>
<li>Button 2</li>
<li>Button 3</li>
</ul>
</div>
and in jQuery as simple as
var min = "-100px", // remember to set in css the same value
max = "0px";
$(function() {
$("#showmenu").click(function() {
if($(".menu").css("marginLeft") == min) // is it left?
$(".menu").animate({ marginLeft: max }); // move right
else
$(".menu").animate({ marginLeft: min }); // move left
});
});

Try this:
<script type="text/javascript">
$.fn.toggleFuncs = function() {
var functions = Array.prototype.slice.call(arguments),
_this = this.click(function(){
var i = _this.data('func_count') || 0;
functions[i%functions.length]();
_this.data('func_count', i+1);
});
}
$('$showmenu').toggleFuncs(
function() {
$( ".menu" ).toggle( "drop" );
},
function() {
$( ".menu" ).toggle( "drop" );
}
);
</script>
First fuction is an alternative to JQuery deprecated toggle :) . Works good with JQuery 2.0.3 and JQuery UI 1.10.3

<script type="text/javascript" src="jquery-1.9.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".click-header").click(function(){
$(this).next(".hidden-content").slideToggle("slow");
$(this).toggleClass("expanded-header");
});
});
</script>
.demo-container {

Use slideToggle(500) function with a duration in milliseconds for getting a better effect.

In your js file, if you need child propagation for the animation then remove the second click event function and its codes.
$(document).ready(function(){
$(".js--growth-step").click(function(event){
$(this).children(".step-details").slideToggle(500);
return false;
});
//for stoping child to manipulate the animation
$(".js--growth-step .step-details").click(function(event) {
event.stopPropagation();
});
});

JQuery UI - How to apply containment to selector that matches multiple divs?

Example:
<div>
<div class='drop'>
<div class='drag'></div>
</div>
<div class='drop'>
</div>
<div class='drop'>
</div>
<div class='drop'>
</div>
<div>
</div>
</div>
$('div.drag').draggable({ containment: 'div.drop' });
Normally, if there is only 1 "div.drop" element, it works as intended. If there are more than 1(like in the example above), I thought that it would be dragged/dropped in any of the "div.drop" divs. As it turns out, it is only draggable/droppable to the first element matched by the "div.drop" selector.
Is there a workaround for this(that is, make it contained/droppable/draggable only in the "div.drop" divs)?
EDIT: I guess you are right guys. After some introspection, I realized that I didn't go for your suggested solutions since there are padding between the divs and I don't want the the "div.drag" divs to be dropped on the padded area.

It don't works like that !!
The containment is to constraint bound of dragging.
You want drag and drop.
Then you have to configure drag for div.grag:
$('div.drag').draggable();
And configure drop for div.drop:
$('div.drop').droppable();
You can add containment for your drag element with your first div level:
<div id='dragZone'>
<div class='drop'>
<div class='drag'></div>
</div>
<div class='drop'>
</div>
</div>
$('div.drag').draggable({ containment: '#dragZone'});

containment restricts the movement of a draggable within the bounds of the given element(s). You could set containment to the parent of the div.drops.
You should make the div.drops droppable, append the draggable on drop, and use the revert: 'invalid' option so that the draggable reverts if it's not dropped on a droppable
$('div.drop').droppable({drop: function(e, ui) {
ui.draggable.appendTo(this);
}});
$('div.drag').draggable({
helper: 'clone',
revert: 'invalid'
});

As the guys have pointed out the containment selector does not work like that as it Constrains dragging to within the bounds of the specified element or region.
You could try something like below:

<script type="text/javascript">
$('div.drag').draggable({ containment: '#dragContainer', revert: "invalid" });
$('div.drop').droppable( {
drop: handleDropEvent

function handleDropEvent( event, ui ) {
var draggable = ui.draggable;
alert( 'Ok to drop here onto me!' );
}
</script>

Do try my code
<style>
.container {
border: 2px solid #000;
}
.container img {
width: 45px;
height: 45px;
}
.draggable {
width: 40px;
height: 40px;
background: #F90;
border-radius: 10px;
margin: 0 0 0 0;
float: top;
}
.draggable.is-pointer-down {
background: #09F;
z-index: 2; /* above other draggies */
}
.draggable.is-dragging { opacity: 0.7; }
</style>
<script>
$(document).ready( function() {
var $draggables = $('.draggable').draggabilly({
// contain to parent element
    **containment: "#box"**
});
});
</script>
Hello. I think this might help you :)
<div class="container" id="box">
and my images are inside this div.
