Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, I am having a few probs with the below

print "Content-type: text/html\n\n";

print "<html><head><script="javascript" src="demo.js"</script><title>T
+ESTING</title></head>";

....
<FORM ACTION="expandtree.cgi" METHOD="POST"
ENCTYPE="multipart/form-data">

<div align="left"><br>
<input type="checkbox" name="option1" value="N" checked> N-linked<br>

<SELECT MULTIPLE NAME=demo SIZE=2>
<OPTION VALUE="A1">A1 
<OPTION VALUE="A2">A2 

</SELECT>
<INPUT TYPE=button VALUE="Select All" ONCLICK="selectAll(this.form.dem
+o,true)">
<INPUT TYPE=button VALUE="Clear All" ONCLICK="selectAll(this.form.demo
+,false)">

function selectAll(cbList,bSelect) {
  for (var i=0; i<cbList.length; i++)

A few things. You don't have the complete code listed or the error you are seeing. This information could help us help you. I would also do some searches as these issues have been touched on before here. And I would try your js in a static html page to make sure it works in a clean environment.

If you change those `print "<html here>"; to print qq(<html here>);` (or q() see perlop), I bet it will work. Other then that we'll need a better description of the problems your having with it.

There is nothing in your 'print' lines that needs to be interpolated, you could just change for example: `print "<html><head><script="javascript" src="demo.js"</script><title>T +ESTING</title></head>";` [download] to `print '<html><head><script="javascript" src="demo.js"</script><title>T +ESTING</title></head>';` [download] Not sure if this is your issue, but you have unescaped "s in the line.

Can I suggest that you put the closing angle bracket on the `script` tag? ie. change: `<script="javascript" src="demo.js"</script>` [download] to `<script="javascript" src="demo.js"></script>` [download] Personally I would change that entire line to read: `<script type=\"text/javascript\" src=\"demo.js\"></script>` [download] Why, you ask? Well a tag name (such as `script`) should have a space before the first argument (`type=\"text/javascript\"`). Also the quote marks should be escaped within a Perl string as mentioned above. update: reformatted mis-escaped `<code>` tag. update: accidently pressed the update button twice.

Nice catch, I completely missed that one. Especially after the cutting, and pasting. ;)	[reply]
