embedding javascript using html into perl script

happyse27

Hi All,

I am creating the perl script using html form(with embedded javascript inside).

When using this html form with javascript alone, it works where the form validation will pop up javascript windows to say the field is not keyed into properly. However, when i convert this html(with javascript inside) into perl script, the perl script did not validate when i keyed incorrect data in the form and it straight away executed perl script without using the java script validation.

The code is below.

Thanks and Best Rgds,
Andrew

pls advise why onsubmit="return ValidateForm1('this')" did not work in the form validation... The below example worked however...

Expand|Select|Wrap|Line Numbers

 
#!c:/perl/bin/perl.exe -w

#!/usr/local/bin/perl
 
my $random_number = int( rand( 10)); 
 
print "Content-type: text/html\n\n";

print qq|
 
<html> 

<head> 

<title>A Random Number</title> 
 
<script language="JavaScript" type="text/javascript">

var myNumber = $random_number; 
 
function display() { 

alert( "Your random number is "+ myNumber); 

} 

</script> 
 
<style> 

.display { padding: 50px; text-align: center; background: lightblue; } 

</style> 
 
</head> 
 
<body> 

<div class="display" onMouseOver="display();">HOVER HERE TO SEE THE NUMBER!</div> 

</body> 
 
</html> |;

In your first code you have this:

Expand|Select|Wrap|Line Numbers

  
print qq%
 
#this portion will be html with javascript alone, except %; at the closing end.

You need to remove the line that starts with # because that is not a comment that is just text inside of a qq string and the % symbol is breaking your code in that line. I don't know if that will make your javascript code work but it should make your perl code work.

oh, the # comment was not part of the code. Only my comments... at wits end. Surveyed many websites... still not able... thanks...
