stefanocerra Obsessive-Compulsive (I) Inmate From: Bologna, Italy Insane since: Feb 2003	posted 02-05-2003 16:57 maybe i'm asking something idiot.. please forgive me! I'm trying to use some javascript function in a xsl stylesheet, and it doesn't work. Theese are the functions: <script language="JavaScript"> <!-- function MM_reloadPage(init) { //reloads the window if Nav4 resized if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) { document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }} else if (innerWidth!=document.MM_pgW \| \| innerHeight!=document.MM_pgH) location.reload(); } MM_reloadPage(true); //--> function MM_findObj(n, d) { //v4.0 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);} if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n]; for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); if(!x && document.getElementById) x=document.getElementById(n); return x; } function MM_showHideLayers() { //v3.0 var i,p,v,obj,args=MM_showHideLayers.arguments; for (i=0; i<(args.length-2); i+=3) if ((obj=MM_findObj(args[i]))!=null) { v=args[i+2]; if (obj.style) { obj=obj.style; v=(v=='show')?'visible' v='hide')?'hidden':v; } obj.visibility=v; } } //--> //--> </script> I copied them from a html document made with dreamweaver! And I tried to call them in the stylesheet in this way: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl utput method="html" /> <xsl:template match="/"> <head> <title> - </title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"></meta> ... <!-- I create a layer with div tag and the name is given through a generete-id function --> <div id="generate-id(.)" style=" visibility: visible"><b><xsl:value-of select="./numnota" /> </font><xsl:value-of select="./testonota" /></b> </div> <!-- then i recall the function trying to hidden the layer, referring to the same element and so the same generated id --> <b onClick="MM_showHideLayers('generate-id(.)','','hidden')"> [<xsl:value-of select="./numnota" />]</b> I don't know which is the way to put the javascript functions in the xsl stylesheet! I dont understand why dreamweaver is using comment tags containing the javascript functions... if I erase these tags, and use & etc., the browser can use my stylesheet, but the functions don't work (Errors loading the page...) I hope of having been clear, and that someone can help me! thanks a lot, Stefano
Slime Lunatic (VI) Mad Scientist From: Massachusetts, USA Insane since: Mar 2000	posted 02-05-2003 18:04 In XSLT, anything within comment tags (<!--, --> ) is ignored. Your script is within comment tags. Those must be removed. If you want the transformed document to have comment tags, you must use <xsl:comment>...</xsl:comment>. Secondly, the appearance of an ampersand(& in an XML language means an entity (such as <, for instance) is coming up. So all &'s in your script must be replaced with &amp;. This means you'll have a lot of "if (blah &amp;&amp; blah)" in your script. [edit: stupid UBB messes up character entities; turned all my &amp;'s into &'s] [This message has been edited by Slime (edited 02-05-2003).]

Slime Lunatic (VI) Mad Scientist From: Massachusetts, USA Insane since: Mar 2000	posted 02-05-2003 23:59 Did you actually try the character entities? They're required, and will be parsed into what you intend the code to be. (That is, if you say "if (blah &amp;&amp; blah)", the parser will insert the text "if (blah && blah)" into the HTML document. Or is the problem occuring after it's been put into the document (for instance, it's a javascript error)? If that's the case, then show us the produced HTML code that fails. What is the specific error that you get?

The browser can load the page, but when i click in the place where i activated the javascript, an error message is displayed on the status bar. (I'm using an italian version of Explorer, but the meaning is "Error while loading the page"). In this moment i'm not able to show you the html code, i'll try monday. Thank you a lot. S.
Slime Lunatic (VI) Mad Scientist From: Massachusetts, USA Insane since: Mar 2000	posted 02-07-2003 17:38 Double-click the text "error while loading the page," and a more detailed error message should appear. It will also give you the line number in the HTML code that the error appears. You can look into the HTML code with right click -> view source to see what's on that line, and then see if you can figure out what went wrong. If you commonly develop with JavaScript, you should also click the "Always display this when a page has errors" checkbox on the error report.

maybe i'm asking something idiot.. please forgive me!

I'm trying to use some javascript function in a xsl stylesheet, and it doesn't work.
Theese are the functions:

<script language="JavaScript">



function MM_findObj(n, d) { //v4.0
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && document.getElementById) x=document.getElementById(n); return x;
}

function MM_showHideLayers() { //v3.0
var i,p,v,obj,args=MM_showHideLayers.arguments;
for (i=0; i<(args.length-2); i+=3) if ((obj=MM_findObj(args[i]))!=null) { v=args[i+2];
if (obj.style) { obj=obj.style; v=(v=='show')?'visible' v='hide')?'hidden':v; }
obj.visibility=v; }
}
//-->
//-->
</script>

I copied them from a html document made with dreamweaver!

And I tried to call them in the stylesheet in this way:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl utput method="html" />

<xsl:template match="/">

<head>
<title> - </title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"></meta>

...



<div id="generate-id(.)" style=" visibility: visible"><b><xsl:value-of select="./numnota" /> </font><xsl:value-of

select="./testonota" /></b> </div>



<b onClick="MM_showHideLayers('generate-id(.)','','hidden')"> [<xsl:value-of select="./numnota" />]</b>

I don't know which is the way to put the javascript functions in the xsl stylesheet! I dont understand why dreamweaver is using comment tags containing the javascript functions... if I erase these tags, and use & etc., the browser can use my stylesheet, but the functions don't work (Errors loading the page...)

I hope of having been clear, and that someone can help me!

Well i have to explain... in the former example i was using the tag <script> in the head section of the html code generated by the xsl stylesheet. If i erase the comment tags i have to use the entity names & and < --- and the functions don't work.

Then i tried to do something like that:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:lxslt="http://xml.apache.org/xslt"

version="1.0">

<xsl utput method="html" />

<lxslt:script lang="JavaScript">

function MM_reloadPage(init) {
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
else if (innerWidth!=document.MM_pgW | | innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);

function MM_findObj(n, d) {
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && document.getElementById) x=document.getElementById(n); return x;
}

function MM_showHideLayers() {
var i,p,v,obj,args=MM_showHideLayers.arguments;

}

<xsl:template match="/">

etc...

But it doesn't work again!
