Is it possible to pass a value from JSP to Javascript

[Ramesh Shanmugam]

I have a JSP page, in which i need to pass a Value of a Text box to a Javascript.
IS it possible to do so.

You can write the value that's known during HTML generation to the Javascript using JSP code before the HTML is sent to the client.
You can use Javascript to read the actual value at the client at any time, read a Javascript book.

How often must we repeat: JSP is SERVERside code, Javascript is CLIENTside code. They can NOT interact during execution.

Here is an example

 
<script language="JavaScript">
 
var jsColumnType;
var jsColumnName;
var jsColumnSize;
var jsIsColumnNull;
 

function getColumnDetails() {
    <% 
    int index=0;
    while(enumColumnType.hasMoreElements()
    %>
 
       jsColumnType[<%=index%>]='<%=enumColumnType.nextElement()%>';
       jsColumnName[<%=index%>]='<%=enumColumnName.nextElement()%>';
       jsColumnSize[<%=index%>]='<%=enumColumnSize.nextElement()%>';
       jsIsColumnNull[<%=index%>]='<%=enumvColumnIsNull.nextElement()%>';
    <%
      index++;
    }
    %>  
</script>
