I've using the first example by this code: http://jqueryui.com/draggable/#handle like this:
$(function() {
$("#draggable").draggable({
handle: "p"
});
});
#draggable {
width: 100px;
height: 100px;
padding: 0.5em;
float: left;
margin: 0 10px 10px 0;
}
#draggable p {
cursor: move;
}
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.2/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.2/jquery-ui.js"></script>
<div id="draggable" class="ui-widget-content">
<p class="ui-widget-header">I can be dragged only by this handle</p>
</div>
I would to start touch outside "draggable handle" and activate it when mouse passing over it.
I try to explain better with an image:
Is it possibile? How can I do this?

I am using jQuery draggable. I have added draggable function to main div. Now in all the child elements it's also draggable. How can I disable dragging inside child div if parent is draggable?
$(function() {
$("#draggable").draggable();
});
#draggable {
width: 150px;
height: 150px;
padding: 0.5em;
border: black solid 2px;
}
.noDrag {
width: 100px;
height: 50px;
border: blue solid 2px;
}
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<div id="draggable" class="ui-widget-content">
<p>Drag me around</p>
<div class='noDrag'>No Drag</div>
</div>
To fix this use the cancel property, and provide it a selector to match the element you want to disable the drag behaviour on, like this:
$(function() {
$("#draggable").draggable({
cancel: '.noDrag'
});
});
#draggable {
width: 150px;
height: 150px;
padding: 0.5em;
border: black solid 2px;
}
.noDrag {
width: 100px;
height: 50px;
border: blue solid 2px;
}
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<div id="draggable" class="ui-widget-content">
<p>Drag me around</p>
<div class="noDrag">No Drag</div>
</div>
you can use cancel or disableselection() like suggest in jQuery-ui documentation https://jqueryui.com/draggable/#handle

I'm trying to implement a drag-drop scenario.
A problem that I'm having is that I need to drop an element on an outer div but the event fires on the inner div.
Here is a codepen to demonstrate my problem:
http://codepen.io/anon/pen/KdvboR
<html>
<head>
<style>
.dropDiv {
height: 100px;
width: 200px;
border: 1px solid black;
}
.innerDiv {
height: 100px;
width: 100px;
border-right: 1px solid black;
}
.drag {
border: 1px solid green;
}
.drop {
border: 1px solid red;
}
</style>
</head>
<body>
<span id="text" draggable="true" ondragstart="drag(event)" ondragend="dragend(event)" class="">Drag Text</span>
<br>
<br>
To Here:
<div class="dropDiv" ondrop="drop(event)" ondragenter="dragenter(event)" ondragleave="dragleave(event)" ondragover="allowDrop(event)">
<div class="innerDiv"></div>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
function allowDrop(ev) {
ev.preventDefault();
}
function drag(ev) {
$(ev.target).addClass('drag');
ev.dataTransfer.setData('text', ev.target.id);
}
function dragenter(ev) {
$(ev.target).addClass('drop');
}
function dragleave(ev) {
$(ev.target).removeClass('drop');
}
function dragend(ev) {
$(ev.target).removeClass('drag');
}
function drop(ev) {
ev.preventDefault();
var data = ev.dataTransfer.getData('text');
ev.target.appendChild(document.getElementById(data));
$(ev.target).removeClass('drop');
}
</script>
</body>
</html>
I need that whenever the dragged element is in the outer div the border will be red. but when the mouse is over the inner div, only the inner div's border is red.
Any suggestions?
Thanks.

You are only one div on your container. remove container and try
<div class="innerDiv" ondrop="drop(event)" ondragenter="dragenter(event)" ondragleave="dragleave(event)" ondragover="allowDrop(event)"></div>
<div class="innerDiv" ondrop="drop(event)" ondragenter="dragenter(event)" ondragleave="dragleave(event)" ondragover="allowDrop(event)"></div>
.innerDiv {
height: 100px;
width: 100px;
border: 1px solid;
float:left;
}
Thanks everybody,
eventually, I solved it by checking if the event coords are in the outer div.
$(document).ready(function() {
$( "#box" ).resizable();
});
.container {
width: 450px;
height: 450px;
background-color: #000;
}
#box {
width: 150px;
height: 150px;
background-color: red;
padding: 0.5em;
}
<div class="container">
<div id="box">
</div>
</div>
All I see is a red box, inside a black box, cannot see the resize icon at all like in the example here:
http://jqueryui.com/resizable/#helper
I looked at their css file, it seems like with the class .ui-widget-content it works, but why?
What makes that resize icon popup in there?
Why doesn't it work?

You're missing the jQuery UI stylesheet:
<link href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" rel="stylesheet"/>
The entire jQuery UI project uses stylesheets to determine the look and feel of the widgets. The resizable icon is in the stylesheet:
.ui-icon-gripsmall-diagonal-se {
background-position: -64px -224px;
}
.ui-icon, .ui-widget-content .ui-icon {
background-image: url("images/ui-icons_222222_256x240.png");
}
The width and height of your element is controlled via styles. On the jquery download page, there is a section (at the bottom) to customize the look and feel. You're free to design your own; the one that I referenced is the default.
Just use this....
#box { resize:both; }
in css
I've been having some trouble getting JQuery UI selectable to work with my site. I'm still very new to coding and I'm not sure what I'm doing wrong. I've searched for relevant questions and haven't been able to find any that let me figure it out.
I'm trying to create whats essentially a glorified label maker for work, and would like to be able to select cells in a grid using a mouse "lasso." But for some reason, I can't get selectable to work at all.
Here is the js:
$('document').ready(function() {
for (i=0; i<117;i++) {
$('#plateActual').append('<div class="cell"/>');
}
$('#plateActual').selectable();
});
Here is the HTML:

margin: 0px auto;
padding: 0;
}
.cell {

border: 1px dotted;
}
I apologize if my code is messy and unorganized. I am still figuring out how to best keep it organized and generally write it in an acceptable fashion. Thanks a lot for your help.
Update: I've made the change Ando suggested, but I'm still unable to get selectable to work. I've tried changing #plateActual to an ol or ul and appending li.cell instead but that did not work either.
I was wondering if the reason is my css is somehow interfering with it, but I'm not sure how to fix that without destroying the formatting.
The element returned by append will be the element to which the add is performed - in your case plateActual- so you will be adding the cell class to the wrong element.
When you append the cells - you use $('<div/>') - which will translate to "get the elements of type '<div/>' from the dom and move them inside my 'plateActual' element" - you should add without $ as you are creating an element that does not yet exist.
Something like this should work (http://jsfiddle.net/k3YJY/):
for (var i=0; i<5;i++) {
$('#plateActual').append('<div class="cell"/>');
}
i have a drag and drop code here from jquery i wanted to get the value of the image then insert it to the database and when the image is remove from the droppable area then update and remove the image value.. how can i do it?

Off the top of my head something like this should give you the src of the image
drop: function( event, ui ) {
var image_src = $(ui).attr('src');
