Im developing a web page, where i can drag one image upon another background image and merge them...
my problem is , i want to know the position of dragged image by the user..
im using php and javascript functions to develop this...
please anybody know about this ..please get me information..
thanks in advance..
Shanti.
Hello Shanti, theImage.offsetTop and theImage.offsetLeft will give you the values you need to display to your user.
Than you can chose where you like to display them.
most probably in: window.status = theImage.offsetTop +" : " + theImage.offsetLeft p.s.:
For the values to get dynamically updated, you should use it inside your imagedrag function.
Regards.

INSTRUCTIONS:
=============
Step One:
---------
Place this script in the head of the page.
Set the six dimensioning variables where
shown in the script (below).
Step Two:
---------
In the body, give each image a unique name
and attach the functions as shown:
<img src="someimage.jpg"name="imageOne"width="100" height="100"onDrag="dragResizeImage(event,this.name)"
onClick="clickResetImageSize(this.name)">
<img src="anotherimage.jpg"
name="imageTwo"
width="100" height="100"
onDrag="dragResizeImage(event,this.name)"
onClick="clickResetImageSize(this.name)">
Any number of images may be used; however,
all should usually be the same default size.
Step Three:
-----------
Add the iBeReady variable to an onload event
in the body tag:
<body onload="iBeReady=true;">
*/
// THE SCRIPT:
// ===========
// sets the default size of the image(s)
defaultXsize = 100;
defaultYsize = 100;
// sets the minimum size of the image(s)
minimumXsize = 50;
minimumYsize = 50;
// sets the maximum size of the image(s)
maximumXsize = 250;
maximumYsize = 250;
// Do not edit below this line.
// ----------------------------
iBeReady = false;
function dragResizeImage(dragEvent,which){
alert(which);
if (iBeReady){
posX = eval("document."+which+".offsetLeft");
posY = eval("document."+which+".offsetTop");
newXsize = dragEvent.x;
newYsize = dragEvent.y;
newXsize = newXsize - posX;
newYsize = newYsize - posY;
if (newXsize >= maximumXsize) newXsize = maximumXsize;
if (newYsize >= maximumYsize) newYsize = maximumYsize;
if (newXsize <= minimumXsize) newXsize = minimumXsize;
if (newYsize <= minimumYsize) newYsize = minimumYsize;
eval("document."+which+".width=newXsize");
eval("document."+which+".height=newYsize");
}
}
function clickResetImageSize(which){
if (iBeReady){
eval("document."+which+".width=defaultXsize");
eval("document."+which+".height=defaultYsize");
}
}
function frame(id){
document.getElementById("div1").setAttribute("background","themes/New Folder/imgb"+id+".gif");
}
function frame_image(id){
document.getElementById("div2").setAttribute("src","images/img"+id+".jpg");
}
