how do i pass a javascript Array from a
jsp to a
servlet??
in my javascript script tag i have written this code
what i m trying to do is pass all the values of the list box to array and pass this array to servlet for inserting into the database.
function addVar()
{
//alert("hi");
var val=new Array();
val=document.getElementById("ListedSubjectID");
var i=val.length;
//alert(i);
for(var j=0;j<i;j++)
{
//alert(val.options[j].Value);
val.options[j].Value;
}
document.getElementById("Val1")[0].value=val;
}
where Val1 is the hidden field.
and ListedSubjectID is the list box name
and in my servlet i did something like
String values[]=request.getParameterValues("Val1");
for (String value : values)
{
System.out.println("The value is "+value);
}
String value=request.getParameter("Val1");
System.out.println("The Parameter value is "+value);
i tried both the methods but it does not print any thing.
the value of values[]=""
and value is =""
please help
