dynamic images

[twopeak]

Hello

How do I get the alt tag of an image to appear in a textbox?
this is what I'm trying

function addsmile(image_ name) {
var smiley;
smiley = document.image_ name.alt; // <= THIS RULE SHOULD BE CORRECTED!!!!!
doc_content = document.form.b ericht.value + smiley;
document.form.b ericht.value = doc_content;
document.form.b ericht.focus();
}

so when a user clicks a link, it sends the name of the image to the
function, and smiley should be the alt tag of the image!
if the variable image_name = "een"
then the line should be
smiley = document.een.al t;

thank you very much for any help!

You should never assume that a named element can be accessed as just
"name" or "document.name" . Some browsers allow it, others don't, but
it is always safer to go through the propert collections:

smiley = document.images[image_name].alt;
[color=blue]
> doc_content = document.form.b ericht.value + smiley;
> document.form.b ericht.value = doc_content;[/color]

var berichtElem = document.forms['form'].elements['bericht'];
berichtElem.val ue += smiley;
[color=blue]
> document.form.b ericht.focus();[/color]

berichtEleme.fo cus();
[color=blue]

It should be
smiley = document.images .een.alt;
but since "een" is stored in the string called "image_name ", it's
smiley = document.images[image_name].alt;
