RE: Passing JavaScript variable to a Java Scriptlet on a JSP page

[Oliver Reflé]

I don't know exactly why you want to do that ?
Why don't you use
<% Hashtable states = new Hashtable();
states = Combo.getStates(country);
....
%>
and then you use
Country: <%=country.toString()%>

You don't need to use this javascript stuff, cause the disadvantage
is that you execute this document.write stuff on the client side.
You first execute you java scriptlet, the transfer the date to the
client and there the javascript code is executed.

So it would be easier if you would only work with Java scriptlets or Tags
here

Subject: Passing JavaScript variable to a Java Scriptlet on a JSP page


Hi,

I have this piece of code on my JSP:

<Script language = "javascript">
 function fnGetStates()
 {
country = document.searchAcctForm.cboAcctAddrCountry.value;
alert(country);
document.write('<% Hashtable states = new Hashtable(); %>');
document.write('<% states = Combo.getStates(country);%>');
document.write('<% Enumeration state = states.keys(); %>');
document.write('<% while (state.hasMoreElements()) { %>');
document.write('<% String statecode = (String)state.nextElement(); %>');
document.write('<% String sts = (String)states.get(statecode); %>');
document.write('<html:option value="<%= statecode %>"><%= sts
%></html:option>');
document.write('<%  } %>');
}
</Script>


The problem is that "alert" is able to show the value of country. But within
the document.write, It  is not able to get the value of "country". It throws
the following error :

~:\citione\web\WEB-INF\_tmp_war_myserver_myserver_web\jsp_servlet\_jsp\_sear
ch\__searchacct.java:801: cannot resolve symbol
probably occurred due to an error in /jsp/search/searchacct.jsp line 197:
document.write('<% states = Combo.getStates(country);%>');
Could some one help ?
Thanks
Sanjeev
