Hii lch

Two ways to do the thing
1)for that u need to assign values at the runtime.
  like
   <script>//define javascript array
             var arr=new Array()
            //assign values to this array
             <% for(i=0;i<=10;i++) %>
              arr[<%=i%>]=<%=jsparray[i]%>
       </script>
2)alternative apporach is that make a combined(join) values of all the jsparray element separated by "~" and pass it to the javascript function ,now javascript function split that value on the "~" basis and that returns the array.

Note-it's not possible to pass the serverside array to the client side javascript function ,so you will have only two approaches.
If there is any other method then let me know.
Hope this will help you

Cheers :)

thx !!! i am grateful to ur helping!!!

i think i need to explain clearly to u all !!1

now i have 2 files: middle.jsp and body.js

in the middle.jsp

<%
Collection result = menuManager.getUserRoleMenu(webSessionUser.getGnus erId());

String menuname[]=new String[200];
int menucounter=0;
Iterator vi = result.iterator();
while(vi.hasNext())
{
HashMap hm=(HashMap)vi.next();
menuname[menucounter]=hm.toString();
menucounter++;
}
%>
<html>
<body>
....

the other one is the body.js ! it is the collection of the methods !!!

i want to pass the string array:menuname to the body.js ???
so ...what can i do ???

now ....my senior advise me like below:
use the form to pass the value !!

<script language="javascript">
function djfkd()
{
var abc=documen.form0.(hidden name).value;
}
</script>
<form name=form0>
<input type=hidden name=??? value="value in jsp">
</form>

Hiii Ich !!!

Life is very cool to enjoy lets make it simple :)
I am also a new student in programming

copy this code on new jsp page
and run it,please import all the required class.

<script language="javascript">
function ShowValue(arrvalues)
{
myarray=arrvalues.split("~") //here menuname(==myarray) will be actual Array that you want to pass
//since we can not pass directly array to the client side variable

for(i=0;i<myarray.length-1;i++)
{
alert(myarray[i])
}
}
</script>
<%
Collection result = menuManager.getUserRoleMenu(webSessionUser.getGnus erId());

String str=""
Iterator vi = result.iterator();
while(vi.hasNext())
{
HashMap hm=(HashMap)vi.next();
str=str+hm.toString()+"~";
}
%>

<script>
ShowValue('<%=str%>');
</script>

Hope this will help you

Cheers :)

dear vinod,

i have read ur code already, and i have tested it ....

now i have 2 questions:
1. if use the "alert" , it will pop- up the message , but i dun want the message! must use the "alert" to pass the value from jsp to js ?? as i know, "alert" 's function just pop up the message only , not for the value passing!!!or u just want to show me the content of the string array :) hehehe!!

2.in the body.js , it is the "destination" of the value passing !! how can i get and store the string ?? or i can use the "myarray" directly in the body.js!! how to initiate in the body.js???

sorry , i just touch the javascript less than 1 month ...so, it is strange to me !!! i am doing the java application!!! i never touch the javascript before !!!

thx for ur helping !!!
