    radio button value

    in JavaScript

    Posted · Edited by jwzumwalt

    dsonesuk - Thank you for taking the time to explain the problem AND provide the solution.
    I use to write most my web programs in PHP and have started to convert many of them to JS - would have never figured this out :)
    I do keep good notes, and won't have to go through this again!

    radio button value

    in JavaScript

    Posted

    I am trying to get the value of a radio button.

    The value of the radio button should get put into the answer box.
    Why won't the radio value get returned and/or shown?
    Thx
      

    <head>
  <script>
    function test() {
      var myinput = document.getElementById("guess").value;
      document.getElementById("answer").value = myinput;
    }
  </script>  
</head>

<body>
  <input type="radio" name="guess" value="1"> One<br>
  <input type="radio" name="guess" value="2"> Two<br>
  <input type="radio" name="guess" value="3"> Three<br>
  <input type="radio" name="guess" value="4"> Four<br>      
  <br>
  <br>
  Answer  <input type="text" id="answer" size=8 style="background-color:#cfc;">
  <br>
  <br>
  <button onclick="test()">Calculate</button> 
</body>

     

    js causes form submit

    in JavaScript

    Change the function name so it does not match id or name attribute values for example id="bankdate' or name='bankdate', its a conflict.

     

    That fixed it! Thanks :)

    (I am still baffled why this caused a form submission...)

    I cant get this PHP code for contact form to work

    in PHP

    The link provided did not work so I could not check the source code.
    A better pattern match is
    $pattern = "/^(+d{1,2}s)?(?d{3})?[s.-]d{3}[s.-]d{4}$/";
    The if statement has two errors.
    1) a elseif is needed
    2) a condition/check is needed for the elseif
    There are two else in a row; this is not allowed.
    it looks like the proper code should be just a single else like this...
      //Check for a valid phone number  if (!empty($_REQUEST['phone'])) {  // something was sent    $phone = $_REQUEST['phone'];    $pattern = "/^[0-9_]{7,20}/";    if (preg_match($pattern,$phone)){       $phone = $_REQUEST['phone'];    } else {   // illegal chars      $errors[] = 'Your Phone number can only be numbers.';    } // end of preg_match  } else {   // no entry - blank    $errors[] = 'You forgot to enter your Phone number.';  } // end of !emptyThis is how the code would be if more than one condition needed to be checked.// proper form of "if...elseif...else"if ( condition ) {// Type your code here} elseif ( condition ) {  // other code} else {  // other code}  //Check for a valid phone number  if (!empty($_REQUEST['phone'])) {    $phone = $_REQUEST['phone'];    $pattern = "/^[0-9_]{7,20}/";    if (preg_match($pattern,$phone)){       $phone = $_REQUEST['phone'];    } else {       $errors[] = 'Your Phone number can only be numbers.';  }  else {       $errors[] = 'You forgot to enter your Phone number.';    }

     

    js causes form submit

    in JavaScript

    Posted · Edited by jwzumwalt

    I am not a accomplished js programmer. I am trying to get

    JS to fill a input box with today's date when a button is clicked.

    I am using Google Chrome. For some reason the code causes

    a form submit which I do not want because I would like other

    form input fields to be able to be filled in. I have done quite a

    few other js forms and never had this problem.

    What am I doing wrong?
