Hi there, I just found these forums and several questions I had have been answered by just reading the posts but this one.
I have simplified my code in order to just get to the point with my question.
This is my html code: -
<html>
-
<head>
-
</head>
-
<body>
-
-
<img id="img1" src="images/smile.jpg" style="border:#0000FF solid 2px;"/>
-
-
<script language="javascript">
-
-
my_image = new Image;
-
my_image.src="images/sad.jpg"; my_image.style.border="#FFFFFF solid 5px";
-
-
x=document.getElementById("img1");
-
x=my_image;
-
</script>
-
-
</body>
-
</html>
-
Before I set "x=my_image ", the x object is referring to the image object within the document, so far so good. After the assignment, x is referring to the my_image object and now there is no relationship at all with the image within the document. What I want to accomplish is for the image object within the document to be referring to the my_image object so it updates all of the properties I pre-set for my_image(which will be several in my real code). How can I do that?, or is it best to remove the image object and then append the new my_image to the document(or to the container that will hold it)?
I want to do an image slicing within an html document so I would be updating that object with different images and properties through an adequate set of controls and javascript events of course, this code is just the idea to present my problem.

The Image object is not an html element. It does have a src property, which you can read and apply to an img element.
my_image = new Image();
my_image.src="i mages/sad.jpg";
document.getEle mentById("img1" ).src= my_image.src;

The Image object is not an html element.
dont want to be a wise-guy, but i think you might be wrong: -
var i = new Image(100,100);
-
-
alert(i.constructor) // "HTMLImageElement"
-
-
// also it can be appended just like any other element:
-
-
i.src="http://bytes.com/forum/customavatars/avatar117351_1.gif";
-
document.body.appendChild(i)

>> How can I do that?, : you can't. once its in the dom, you have to use dom MPEs to alter it in a way that changes appear.
>> or is it best to remove the image object and then append the new my_image to the document(or to the container that will hold it)? : thats what i would do, or perhaps give the tag a id, and put all of your images inside the container, img.style.displ ay="none".
then simply 1. hide all of them. 2. show the one you need. to change the image.

Hello,
I am trying to open a window containing an image and I would like
the image to be flush against the window -- i.e. have no padding or
border. Can I make this happen with a single call to a window.open
function? I would prefer not to create a separate HTML page. So far
all I have is the basic
var cwin = window.open('images/KJV-THANKS.gif',
'Thanks', 'width=243,height=420,');
cwin.focus();

Hello All,
I¡¯m using a context menu associated with some pictureboxes to provide
copy/paste functionality. Copying the image to the clipboard was easy. But
pasting an image from the clipboard is proving to be more difficult. These
pictureboxes are bound to an AccessDB. If the user wants to add an image,
they select an image using an OpenFileDialog:
Dim result As DialogResult = Pic_Sel.ShowDialog()
If (result = DialogResult.OK) Then

Hello, I am daring to stick my head above the parapet and ask as
question. I am working on redesigning a website to use CSS rather than
tables for layout. I have come across a problem when trying to float an

For ease of looking at the problem, I have stripped away other parts of
the page layout, and have just included the "content" section in the
examples below.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
