Loop function in Javascript fails when combined with perl array Can't Post

I am taking backend perl variables and using it at the front end for display. Here is the code.

@head1 and @head2 are the variable names taken from perl script. I use that and display those headers of grid on webpage.

Code
 
var headname1= "@head1";
var headname2= "@head2";



Now, if there are 100 headers, i would have to assign variables 100 times separately. so its better to make it dynamic. Taking values from backend and assigning it to javascript variable. This task will be dynamic. Here is my attempted code for that.

I hav taken all the headers from backend and assigned it to line_array. @line_arry is the name of that array. If i do @line_arry[0] and so on. appropriate values will be displyaed.


Code
var headname=[]; 

for(var i=0;i<total_columns;i++) {
headname[i+1]= "@line_arry[(i)]";
}



This code doesnot work. It displays only the first column. i.e.


Code
 headname[1] = "Order"; 
headname[2] = "Order";


Order is the name of the first header. In headname[2], header of second column should be displayed. but it still displays "Order"

If i write the below code, it displays first and second header.


Code
headname[i+1]= "@line_arry[(0)]"; 
headname[i+1]= "@line_arry[(1)]";



"@line_arry" doesnt work whereas
"@line_arry[0], @line_arry[1] works.
Can anyone suggeest why it is not performing looping action using variable i

You need to provide more details and context. Perl is a server side language and Javascript is a client side language.
