Retrieving values of checkboxes created dynamically

well i don't think request.getParameterValues(). is used here.

According to OP shes says she is dynamically populating set of check boxes with names check1,check2 & check3.....

to my understading we can use request.getParameterValues() when multiple values are associated to same name(control) for example a Multiple select Box where you select multiple values.

@OP

Well if you need get dynamically generated names and their associated values extracting from request. you might have to construct a Map with key parametersName and use it as per you need....

just in a given case i'm assuming that you need to have the hidden values of all the checkboxes.which starts with the name "check" and associated number(assuming it to be a single digit number) with it...

here is how you can do it...

public doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{

HashMap cbmap = new HashMap();

for (Enumeration e = request.getParameterNames(); e.hasMoreElements();) {

String param = (String) e.nextElement();

// checking whether the parameter names is of the pattern "check[0 -9]"

if(param.matches("check\d")){

String value = request.getParameter(param);

cbmap.put(param,value);

}

}

Please excuse me if i was wrong with my understading(Users description).

Hope this might help :)

However,i'd still stand on what my fellow poster have said ppl here will not provide you the code they can give you some advices its your responsiblity to implement things out on the thoughts provided.

REGARDS,

Sorry i was just reconfirming on it... :)

Hope you have a gr8 day

@OP

Guess the below code snippet wud be more brief.

public doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{

HashMap cbmap = new HashMap();

int n = Integer.parseInt(request.getParameter("n"));

for(int i = 1 ; i <= n ; i++){

String str = request.getParameter("check"+i);

// String str[] = request.getParameterValues("check"+i);

cbmap.add("check"+i,str);

}
