Hi all!
I've wrote this code: -
<script type="text/javascript">
-
var largImg;
-
var altImg;
-
var txtTop = '<b>Ottima scelta!</b> Ora compila il form e premi "Ricevi banner". Il codice HTML ti verrà mostrato in questa pagina e, per comodità, ti verrà inviato, via mail, all\'indirizzo da te fornito. Se invece vuoi cambiare il banner premi "Seleziona banner"';
-
var txtButton = 'Cambia banner';
-
var testo = '';
-
var maxLarg = 450;
-
var maxAlt = 80;
-
var diffLarg;
-
var diffAlt;
-
var diff;
-
function setBanner(url, id){
-
window.opener.document.getElementById("testoReceive").innerHTML = txtTop;
-
window.opener.document.getElementById("bannerSel").value = txtButton;
-
largImg = window.document.getElementById(id).width;//parseInt(url.split("/")[url.split("/").length-1].split("_")[0].split("x")[0]);
-
-
altImg = window.document.getElementById(id).height;//parseInt(url.split("/")[url.split("/").length-1].split("_")[0].split("x")[1]);
-
-
txtLarg = "Larghezza: " + largImg + "px";
-
txtAlt = "Altezza: " + altImg + "px";
-
diff = (largImg - altImg) + Math.abs(largImg - altImg);alert(diff);
-
testo += '<table cellpadding="0" cellspacing="0" width="100%">';alert(1);
-
testo += '<tr>';
-
testo += '<td valign="middle">';
-
testo += '<img id="previewBanner" src="' + url + '"/>';
-
testo += '</td>';
-
if(diff != 0){
-
testo += '</tr><tr>';
-
}
-
testo += '<td valign="middle">';
-
testo += txtLarg + '<br/><br/>';
-
testo += txtAlt;
-
testo += '</td>';
-
testo += '</tr>';
-
testo += '</table>';
-
window.opener.document.getElementById("divBanner").innerHTML = testo;
-
diffLarg = (largImg - maxLarg) + Math.abs(largImg - maxLarg);
-
diffAlt = (altImg - maxAlt) + Math.abs(altImg - maxAlt);
-
if(diffLarg != 0){
-
if(diffAlt != 0){
-
var propDiff = (Math.abs(largImg - maxLarg) - Math.abs(altImg - maxAlt)) + Math.abs(Math.abs(largImg - maxLarg) - Math.abs(altImg - maxAlt));
-
if(propDiff != 0){
-
window.opener.document.getElementById("previewBanner").style.width = maxLarg + 'px';
-
}
-
else{
-
window.opener.document.getElementById("previewBanner").style.height = maxAlt + 'px';
-
}
-
}
-
else{
-
window.opener.document.getElementById("previewBanner").style.width = maxLarg + 'px';
-
}
-
}
-
else{
-
if(diffAlt != 0){
-
window.opener.document.getElementById("previewBanner").style.width = maxAlt + 'px';
-
}
-
else{
-
window.opener.document.getElementById("previewBanner").style.width = largImg + 'px';
-
window.opener.document.getElementById("previewBanner").style.height = altImg + 'px';
-
}
-
}
-
window.close();
-
}
-
</script>

It's simple:
1) the caller send an url like "140x257_1. jpg" and an id generated by xsl
2) the function substitute what's in caller page's "testoRecei ve" div with a pre-set variable
3) change the value of a caller page's button
4) get the dimension of the image
5) check which dimension is the higher with a difference. If largImg is higher than altImg, diff will not be 0.
Ex: (5 - 3) + abs(5-3) = 2 + 2 = 4; Ex2: (3 - 5) + abs(3 - 5) = -2 + 2 = 0
6) insert into variable "testo" the HTML code to create a table.
7) use variable testo as HTML of caller page's divBanner div
8) check if the dimensions are higher than a max. If it's, resize the image.
9) set image's width and height.
My problem is: firefox execute the function until "alert(diff )" included. From next istruction don't do anything.
I've tried to remove all table's attribute but nothing change, I've tried to insert <tbody> but nothing.
Someone would help me please?
Thank you.

Does it not even alert 1 on line 22? What error message do you get?
The only alert I have is at line 21. Click here to try.
Pressing "Seleziona banner" ("select banner" translated in english) you have the page. It's an xml page formatted with an xsl stylesheet. The script is inside the xsl code. So if you try to get the source you'll have an xml page. Click here to have the complete xsl file.
Thank you!

In Firefox, I see the error:
window.opener.d ocument.getElem entById("previe wBanner") has no properties
http://www.naera.it/public/xml/bannerNaera.xml
Line 44
I know. But the problem is that previewBanner is create dinamically by the previous lines. So...what's the problem??? Why previewBanner has no properties??? Why in IE work properly???
I don't see anything strange...
My only thought is that HTML added by Javascript isn't accessible by Javascript...bu t...I hope it's possible...
Or...maybe firefox don't insert HTML code contained in variable "testo" into opener page...but why do not should do that?
Uff...I hate Firefox!!!
Thank you all!

In Firefox, the code appears like this (with indents): - testo += '';
-
testo += '';
-
testo += '';
-
testo += '';
-
testo += '';
-
if(diff != 0){
-
testo += '';
-
}
-
testo += '';
-
testo += txtLarg + '';
-
testo += txtAlt;
-
testo += '';
-
testo += '';
-
testo += '';
No wonder it doesn't work!
In addition, your html contains attributes which do not exist. In one inline styling, you say "stile" instead of "style". Also, id names must be unique to one element on a page. You cannot use them more than once.
In your CSS, you have several properties that begin with a 's' so these do not exist.
Also, the values have no unit, such as px, specified.
Validate your html and css for those lists of errors.
Uff...I hate Firefox!!!
Never, ever use IE as a reference to how things should work. It is 10 years behind web standards, particularly the DOM. It is buggy and incomplete in its implementations . Always use a modern browser, such as Firefox, Opera or Safari to initially test your page. Then check in IE to adjust for its quirks and bugs.
Guys I've found the problem...
I don't know why but Firefox want that simbols "<" and ">" must be translated with "<" and ">", differently from IE.
In IE, writing < or > show "<" and ">" like no-code simbols.
Mah...Firefox.. .what a strange browser...
Thank you all!

Glad you managed to fix the problem.
Mah...Firefox.. .what a strange browser...
Have you tested in Opera, Netscape, Safari and others? You'll find, more often than not, that what doesn't work in Firefox won't work with the rest either.
More appropriately, What works in all browsers most likely won't work in IE because it is non-standard or broken.
I hate to keep preaching that but until people understand that coding to IE is coding to a bug, they will constantly have questions as to why things don't work in the modern browsers.
Again, never, ever, ever use IE as a reference for how anything. should work.
