<img> width height

[News]

I am trying to be able to manipulate the width and height of an <img> but do
not seem to be able.

"Yes", I know the JavaScript will "not" manip anything, which is ok. I
simply do not know how to capture the width or height. Once I can do that I
can manipulate them.

Here is the HTML for the <img>
<div class="ImgMnp" id="myImg" onmouseover="im gSize('myImg',' fpImg)">
<img src="images/FirePlace.jpg" width="480" height="640" id="fpImg" />
</div>

Here is the JavaScript I tried to manipulate the <img>
function imgSize(myID,my Img)
{
var myDiv= document.getEle mentById(myID); //get correct <div>
var myImage=documen t.getElementByI d(myImg); //get correct <img>
var myWidth=myImage .style.width; //attempt to capture width of <img>
var myHeight=myHeig ht.style.height ; //attempt to capture height of <img>
alert("myWidth+ , +myHeight"); //show if I this function works
}

Will someone please tell me what I am doing wrong

There is a syntax error in this line, near the end. You're
missing an apostrophe. It should go:

<div class="ImgMnp" id="myImg" onmouseover="im gSize('myImg',' fpImg');">

Don't know if that was what was breaking the code though.

simplest way :

<img src="pict.jpg"
onmousover="ale rt('width = '+this.width+' height = '+this.height)" ;>

maybe your code would be better with :

var myWidth= myImage.style&& myImage.style.w idth? myImage.style.w idth :
myImage.width; //attempt to capture width of <img>
var myWidth= myImage.style&& myImage.style.h eight? myImage.style.h eight :
myImage.height; //attempt to capture height of <img>

idea :
If your image didn't get a width or height style, you can't catch it.

I did not know I need that apostrophe thanks.

Nope did not correct the problem, if I take out these two lines

var myWidth=myImage .style.width;
var myHeight=myHeig ht.style.height ;

the function works, put them in the function crashes.

At first I thought it was a triune if true this else that type statement but
I don't have a clue what it is.

Hu ?

myHeight=myHeig ht

from where comes this 2nd myHeight ?

would be better with the image 'myImag' , no ?

var myWidth=myImage .style.width; //attempt to capture width of <img>
var myHeight=myImag e.style.height; //attempt to capture height of <img>
// ^^^^^^^
alert("myWidth+ , +myHeight"); //show if I this function works
}

yes it was (would have to be).

if myImage has style and myImage has style width,
miWidth is myImage.style.w idth
else
miWidth is myImage width

because perhaps your image has no style (or no width or height style) ?

in fact the error was much more stupid
(all as I've done in my code myWidth=myImage .style.height ! !)

You may spend a long time runing around a stupid mistake

Listen, guys: "Micro$oft must die, and stuff"- but if you still want to
make your solution workable on the damned IE (which is not mandatory
but presuming if), it is not a shame at all to visit
<http://msdn.microsoft. com> and read what the producer has to say about
your question.

MSDN is going to put this sentence in bold soon I guess: "You want to
manipulate width/height - you *don't* hardcode it through the img
attributes, you use style rules instead". The rest of the attractive
reading is on MSDN :-)
