    regarding checkbox

    hello all,

    this is my first post on the site.

    I just want to Know the javascript which is used to disable the checkboxes on click of another checkbox?

    means if we click on checkbox, the other 2, 3 checkboxes should be disabled.

    Actually, i am retriving Questions and their answers from SQL Server using ASP. And the ID's of these Questions and answers are set as value to the respective checkboxes.

    If, I clicked on the question checkbox then the answers checkboxes should be disabled.

    pl help me

      Hi yash777,

      Welcome to The Scripts!

      Give this script a try. It's pretty simple and you should be able to adapt it for your own uses.
      Code:
       <html> 
<head>
 <script type="text/javascript">
 function check()
 {
 var check1 = document.TestForm.Check1
 
 if (check1.checked = true)
  {
  document.TestForm.Check2.checked = false;
  document.TestForm.Check3.checked = false;
  }
 } 
 </script>
</head>
<body>
 <form method="post" name="TestForm">
  <input type="checkbox" value="1" name="Check1" onchange="check();">If I check this checkbox...</input>
  <br /><br />
  <input type="checkbox" value="2" name="Check2" checked="checked">This one and...</input>
  <input type="checkbox" value="3" name="Check3" checked="checked">this one should uncheck!</input>
 </form>
</body>
</html>
      If you have any problems then please let me know.

      Hope this helps,

      Dr B

                  I'm afraid I don't understand what it is you're trying to do.

                  Can you try to explain it a little more clearly with an example and some code if possible? The clearer the question is the more chance we have of quickly helping you out.

                      thanks for ur reply Dr.B,

                      this is my code:

                      <%while not rs.eof%>//////first recordset of Questions
                      <tr>
                      <td height="18" align="center"> <input type="checkbox" name="chkquesti on" value="<%=ID%>" ></td>
                      </tr>

                      <% while not rsd.eof%>//////second recordset of Answers
                      <tr>
                      <td height="18" align="center"> <input type="checkbox" name="chksoluti on" value="<%=rsd(" S_id")%>"></td>
                      </tr>

                      <%wend
                      rsd.movenext()

                      wend

                      rs.movenext()
                      %>


                      So, i want to disable the answer checkbox if the question checkbox is checked.

                          Are the questions and answers coming as pairs? So if I check Question 1(Q1) then Answer 1 (A1) is disabled and if I check Q2 then A2 is disabled and so on?
