Hi Friends,

Please take a look on given codes and find out where I have committed any mistake. Actually I have created 5 buttons and trying to display a pyramid after clicked on button. I am using a javascript function which is catching value. Can you please suggest how can i use switch function with this program.

\<html\>  
\<head\>\<title\>\</title\>  
\<script language=“javascript”\>  
function display(num)  
{  
var i;  
for(i==1;i\<=num;i++)  
{

document.write("_");  
document.write("\<br\>");  
document.write("_,_");  
document.write("\<br\>");  
document.write("_,_,_");  
document.write("\<br\>");  
document.write("_,_,_,_,");  
document.write("\<br\>");  
document.write("_,_,_,_,_");  
document.write("\<br\>");  
document.write("_,_,_,_,_,_");  
document.write("\<br\>");  
document.write("_,_,_,_,_,_,_");  
document.write("\<br\>");  
document.write("_,_,_,_,_,_,_,_");  
document.write("\<br\>");  
document.write("_,_,_,_,_,_,_,_,\*");

}  
}

\</script\>  
\</head\>  
\<body\>  
\<form\>  
\<input type=button name=“pramind1” onclick=“display(5)” value=“Pramind 5”\>  
\<input type=button name=“pramind1” onclick=“display(6)” value=“Pramind 6”\>  
\<input type=button name=“pramind1” onclick=“display(7)” value=“Pramind 7”\>  
\<input type=button name=“pramind1” onclick=“display(8)” value=“Pramind 8”\>  
\<input type=button name=“pramind1” onclick=“display(9)” value=“Pramind 9”\>  
\<input type=button name=“pramind1” onclick=“display(10)” value=“Pramind 10”\>

\</form\>  
\</body\>  
\</html\>
