Issue
I'm quite new to the process of web development, so I apoligise if this seems a really silly question.
Basically, I'm creating a servlet whereby a user will answer 'yes' or 'no' to three 3 questions, and then submit the form.
What I wish to do is to retrieve the value of each button, and store it a data structure such as an array, where I can perform a check on it. However, I am a little lost at this point. Is there a method in java I can call on each button, something along the lines of getValue()?
A look at the code ive developed so far:
out.println("<FORM ACTION=\"Game\" METHOD = \"POST\">" +
"<b>Question 1: Are you over the age of 25?. </b><br> <br>" +
"<input type = \"radio\" name = \"rad1Q1\" onclick = \"getAnswer('a')\"> Yes " +
"<input type = \"radio\" name = \"rad2Q1\" onclick = \"getAnswer('b')\"> No<br>" +
"<br><br><b>Question 2: Are you from planet earth. </b><br> <br>" +
"<input type = \"radio\" name = \"rad1Q2\" onclick = \"getAnswer('a')\"> Yes " +
"<input type = \"radio\" name = \"rad2Q2\" onclick = \"getAnswer('b')\"> No <br>"
Solution
input values in the html form will be submitted as request parameters to the servlet. In the servlet where the form is submitting to, you can do
String rad1Q1 = request.getParameter("rad1Q1");
to get the selected value.
I do suggest you do put the html code in the jsp tho instead of servlet to make the code more clear and easier to maintain.
