JavaScript - How To Drag A Div If A Image In It?

Hey complete beginner to javascript here so sorry if I'm doing something stupid

Basically I've tried to follow this guide to make it so that I can move an image on the page.

I have a style tag in the head

Code:

<style type="text/css">.drag{position: relative;}</style>

I have an image like this:

Code:

<img src="logo.png" class="drag" alt="logo" />

which is obviously in the body

I copied and pasted the code given in the guide:

Code:

<script language="JavaScript" type="text/javascript">
<!--
var _startX = 0;			// mouse starting positions
var _startY = 0;
var _offsetX = 0;			// current element offset
var _offsetY = 0;
var _dragElement;			// needs to be passed from OnMouseDown to OnMouseMove
var _oldZIndex = 0;			// we temporarily increase the z-index during drag
var _debug = $('debug');	// makes life easier


InitDragDrop();

function InitDragDrop()
{
	document.onmousedown = OnMouseDown;
	document.onmouseup = OnMouseUp;
}

function OnMouseDown(e)
{
	// IE is retarded and doesn't pass the event object
	if (e == null) 
		e = window.event; 
	
	// IE uses srcElement, others use target
	var target = e.target != null ? e.target : e.srcElement;
	
	_debug.innerHTML = target.className == 'drag' 
		? 'draggable element clicked' 
		: 'NON-draggable element clicked';

	// for IE, left click == 1
	// for Firefox, left click == 0
	if ((e.button == 1 && window.event != null || 
		e.button == 0) && 
		target.className == 'drag')
	{
		// grab the mouse position
		_startX = e.clientX;
		_startY = e.clientY;
		
		// grab the clicked element's position
		_offsetX = ExtractNumber(target.style.left);
		_offsetY = ExtractNumber(target.style.top);
		
		// bring the clicked element to the front while it is being dragged
		_oldZIndex = target.style.zIndex;
		target.style.zIndex = 10000;
		
		// we need to access the element in OnMouseMove
		_dragElement = target;

		// tell our code to start moving the element with the mouse
		document.onmousemove = OnMouseMove;
		
		// cancel out any text selections
		document.body.focus();
		
		// prevent text selection in IE
		document.onselectstart = function () { return false; };
		// prevent IE from trying to drag an image
		target.ondragstart = function() { return false; };
		
		// prevent text selection (except IE)
		return false;
	}
}

function ExtractNumber(value)
{
	var n = parseInt(value);
	
	return n == null || isNaN(n) ? 0 : n;
}

function OnMouseMove(e)
{
	if (e == null) 
		var e = window.event; 

	// this is the actual "drag code"
	_dragElement.style.left = (_offsetX + e.clientX - _startX) + 'px';
	_dragElement.style.top = (_offsetY + e.clientY - _startY) + 'px';
	
	_debug.innerHTML = '(' + _dragElement.style.left + ', ' + _dragElement.style.top + ')';	
}

function OnMouseUp(e)
{
	if (_dragElement != null)
	{
		_dragElement.style.zIndex = _oldZIndex;

		// we're done with these events until the next OnMouseDown
		document.onmousemove = null;
		document.onselectstart = null;
		_dragElement.ondragstart = null;

		// this is how we know we're not dragging
		_dragElement = null;
		
		_debug.innerHTML = 'mouse up';
	}
}
//-->
	</script>

I have tried putting the javascript in the head and the body but no matter where I put it, I can't drag and drop the image. What am I doing wrong?

Thank you for your time

Hello,

I have a system where one clicks on an image an a floating calculator appear.

<img src="images/groutculatorman.png" width="114" height="85" onclick="showdiv()"/>

<div id="demo" style="visibility:hidden"> <div id="calculator" class="drag">

<script type="text/javascript">


function closeCalculator() {
document.getElementById("calculator").style.display = "none";
window.location.href = window.location.href;}



var ie = document.all;
var ns6 = document.getElementById && !document.all;
var dragapproved=false;
var z, x, y;

function move(e) {
if (dragapproved) {
z.style.left=ns6? temp1+e.clientX-x: temp1+event.clientX-x;
z.style.top=ns6? temp2+e.clientY-y : temp2+event.clientY-y;

PROBLEM

I added a drop down function on the image in order to open different calculators.

The system works however the calculator won't drop (doesn't deselect).

Any ideas.


New code.

<a href="javascript:;" onMouseOver="MM_showMenu(window.mm_menu_1009090908_0,11,82,null,'image1')" onMouseOut="MM_startTimeout();">

<img src="images/groutculatorman.png" name="image1" width="114" height="85" border="0" id="image1">

There seems to be a lot out there, but I haven't found a javascript for a click and drag that has been bug free.

Does anyone have any suggestions?

The last one I had didn't work in Safari.

Thanks so much for any help.

Hello, I'm in need of help on my drag and drop code. How can I make 2 images (1 draggable, 1 static) each switch to alternate images when the draggable is dragged over the static?

Hei,

I should start by saying that I am very new in Javascript.. what I need to do is to drag the entire window...any ideas how to do that ?

Thanks

Hi

When i'm trying to put a picture in empty div it works fine, but when i put the second picture to the div where already is picture, then second picture "disappear".
If i have only one div, then everything is ok, but with 2 or more divs i have issue.


PHP Code:

hi all, i dont know exactly how to explain this but ill give it a go.

What im looking for is to have a database hold a list of images ( or numbers that corrospond to images)... that should be easy enough. The part im having trouble with is having these images aligned in a grid which is inside a window /frame/ box on the web page. The user can click and drag and it will move around this collection of images.....

like so (numbers represent images):

5 4 3
6 1 2
7 8 9

so if the user clicked and dragged to the right the images would then look like:

4 3 12
1 2 11
8 9 10

the new images are taken from the database and the user can drag in any direction.

i hope that makes sence, can someone help with this ? even if its just what this is called that i should search for, ive tried draggable images, scrolling images etc etc


thanks

P.s like google maps

Dear forum

Rather than use a library, I have attempted to write my own attempt at a script that allows multiple elements to be dragged around the page. It starts by loading all divs into an array, and then forms a new array of only divs with the required class name. I believe this script doesn't work for internet explorer, but I am not concerned by this.

As you will see if you run the code below, the script works well for divs containing text, but if I include an image inside a div, then the image will follow the mouse even if the button is released.

I have spent a whole day on this tiny script and really don't know where to go from here! Could anybody shed some light on this please?

Thanks

Matt

Hi. I'm trying to get drag and drop script working from this tutorial:
http://www.webreference.com/programm...mn2/index.html

I want to drag items between columns (DIV's).

Here is my code:
Code:

document.onmousemove = mouseMove;
document.onmouseup   = mouseUp;
document.onmousedown = mouseDown; 

window.onload = function(){
	// Create our helper object that will show the item while dragging
	dragHelper = document.createElement('DIV');

Hi Folks,

I've been trying to create a drag drop homepage like www.bbc.co.uk, google etc.

I can get the basic drag and drop to work, but I can't get the layout to save anywhere. Can anyone please help?

Here is what I have so far.

It uses Glow, which doesn't have any cookie functions apparantly.

Could anyone please help me save my layout, any example code would be much appreciated

Manu thanks

Hello CodingForums! I need some help with drag & drop links / downloads.
I would like an example like the following website;
http://panic.com/

I am creating a website that runs an iFrame with website displayed in it. On that page, in the frame, there is a simple href hyperlink. I have a text element next to the iFrame that is acting as an address bar. I want to be able to drag the link from the frame to the address bar and ondrop have the iframe redirect to the dragged link url. Here is the code I have
Code:

<html>
<head>
<style>
#NetFrame {
border:2px solid #0A9;
height:650px;
width:75%;
Position: absolute;
top:2%;
left:25%;

}
#url {
width:25%;
height:650px;
}
</style>
<script type="text/javascript">
function getUrl() {
var source = document.getElementById('url').value;
loadUrl(source);
}
function loadUrl(source) {
var showUrl = document.getElementById('NetFrame');

NetFrame.src = source;

document.getElementById('url').value="";
}
</script>
</head>
<body>
<form>
<input type="text" id="url" onDragEnd="getUrl()"/>

</form>
<iframe src="link1.html" id="NetFrame"> </iframe>
</body>
</html>

The iFrame is called NetFrame and the Text element is url. I have not coded in 6 years and am stuck here. Please Help, and be specific you are explaining to an absolute novice.

I can't figure out how to drag and drop. I've followed some tutorials but no success. I use Firefox as my browser. Any tutorial you would recommend?

Hi everyone

I am having a bit of trouble with a question that I have been given for my Javascript assignment.

I was given a web page with a series of boxes (created by <div> tags) which could be dragged and dropped anywhere on the web page, and they were dragged by holding the mouse down and dragging, and released when the mouse button was released. The web page can be viewed at http://adamr.hitwebs.net/dragDropOriginal.html and the source can be viewed at http://adamr.hitwebs.net/dragDropOriginal.js.

The assignment was to make any other element drag-and-droppable, so I chose to make a jigsaw puzzle and hence make images drag-and-droppable, but with minimal changes to the script (simply changing the class name and id of my images), the dragging and dropping process is visually very different (the images appear to "stick" to the cursor on mouse up, and you have to actually click a second time to drop the image).

Can someone please help me to fix this so that the drag and drop looks like what the boxes did (an example of what I want is exactly how the smiley faces are dragged-and-dropped at http://elouai.com/javascript-drag-and-drop.php).

My jigsaw puzzle can be viewed at http://adamr.hitwebs.net/drag&Drop.html and the source can be downloaded from http://adamr.hitwebs.net/dragDrop.js.

As you will see, apart from the large sections of script that I added, I only changed about two or three words of the original script, and it stopped working properly as soon as I started using images, which was long before I made my own additions to the script.

Also note that there are A LOT of comments in my code because this is an assignment, and I have to note every change that I made to the original code, as well as put explanatory comments in my own code.

P.S. Please don't tell me to use the script on the smiley face web page that I have provided, as this would not be useful to me. I must amend the script that I was originally given with the boxes. As for the assignment, I have checked this with the teacher, and I will not lose any marks for the terrible drag-and-drop effect as it does not appear to be my fault. This post is purely for my curiosity and because I hate not being able to solve a problem, and to me, this is a problem.

Thanks heaps,
- Adam
