JavaScript - Drag And Scroll Images

Hi All,

I'm new to the CF forums and also to JavaScript. Trying to get a pop-up div to be draggable, but it doesn't seem to be working. Can someone help me out? I'd be very grateful!

JavaScript I'm using:
Code:

//used for dragging div
function agent(v) 
{ 
return(Math.max(navigator.userAgent.toLowerCase().indexOf(v),0)); 
}
function xy(e,v) 
{ 
return(v?(agent('msie')?event.clientY+document.body.scrollTop:e.pageY):(agent('msie')?event.clientX+document.body.scrollTop:e.pageX)); 
}

function dragOBJ(d,e) 
{

function drag(e) 
{ 
if(!stop) 
{ 
d.style.top=(tX=xy(e,1)+oY-eY+'px'); 
d.style.left=(tY=xy(e)+oX-eX+'px'); 
} 
}

var oX=parseInt(d.style.left),oY=parseInt(d.style.top),eX=xy(e),eY=xy(e,1),tX,tY,stop;

document.onmousemove=drag; 
document.onmouseup=function()
{ 
stop=1; 
document.onmousemove=''; 
document.onmouseup=''; 
};
}

//used for pop-up div
function pop(div) 
{
document.getElementById(div).style.display='block';
return false
}
function hide(div) 
{
document.getElementById(div).style.display='none';
return false
}

Also, here is the HTML:
Code:

<a href="#" onclick="return pop('myDiv2')">Pop-up div #2</a> - Hidden div shows upon clicking this link, but it won't drag

<div class="bubble" onmousedown="dragOBJ(this,event); return false;"> 
   <div id="myDiv2" class="parentDisable"> 
   Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
   <p><a href="#" onClick="return hide('myDiv2')">Close [X]</a></p> 
   </div> 
</div>

And the CSS:
Code:

.parentDisable { 
position:absolute;
margin:120px;
padding:20px;
width:400px;
display:none;
z-index:3;
background-color:#DEDEDE;
border:1px solid #DEDEDE;
border-radius:5px; -moz-border-radius:5px; -webkit-border-radius:5px;
}

.bubble { position:fixed; width:400px; top:150px; left:250px; cursor:move; }

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.

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.

hi,
i want to drag the div which have a image in it:
but i find that if i click on the image, i cannot drag the div, (in FF3.5)
any advice would be appreciated.
Code:

<div id="div1">
<imc src="XXX.jpg">
</div>

and i have a JS something like that...:
Code:

drag();
function drag(){
document.onmousedown = startdrag;
document.onmouseup = enddrag;
}

function startdrag(e){
dragobj=e.target;
alert(dragobj.id);
}
......................

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.

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

All I Want To Make Happen Is That If You Drag and Drop A Div Into A Table An Action Happens

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?

Hi all,

I'm currently developing a drag on drag editor at work.

I have a list of fields on the right which I drag onto a form and it adds the input object onto the form. I also have editable divs which I using to add text as a kind of very scaled down RTE.

Rather than dragging a field the form, I could use the field as display only so I would like to embed this into the editable div as part the text.

I'm thinking I could do something like facebook does where if I type a "@" then I could create a auto suggest to embed a field value into text but what i would like to do is drag the field into the text.

So my question is this, is it possible to know the positon in the text of where I performed the drop, I suppose that would be where the mouseup occurs?

Any thoughts much appericated,
Thanks,
Dale

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 setting up a website where we want a drag n drop solution for a customer to place an email.
To give you an idea on what we want, picture this...
A form where the customer can enter there details.
Below the form are icons of items.
The customer can then drag these items into an image of a box below.
Would also be nice if it could list what is "in" the box.
Once customer is satisfied, the contents get emailed to us and we can provide further details from there.
Mainly has to look nice from the customers side, on our side we are happy to receive just the titles or codes of what they are dragging into this box.

Hopefully i have made this simple to understand, if anyone needs any more information, please do not hesitate to ask me.

Also, this will be implemented into a Joomla site once sorted out, if that makes any difference.

Thank you in advance!

Has anyone modified this script to drag multiple items?

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.

http://www.sandwell.nhs.uk/test/test.html

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

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;
