    Question Disable Certain Input Boxes With Javascript

    I'd like to disable certain input boxes, but without changing the HTML code manually.

    For example:
    I'd like to disable the input boxes with the following id's:
    id="first_field"
    id="fourth_field"
    id="sixth_field"


    HTML Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Disable Certain Input Boxes With Javascript</title>
    </head>
    
    <body>
    
      <div>
        <form action="">
          <fieldset>
            <input type="text" id="first_field"/>
            <input type="text" id="second_field"/>
            <input type="text" id="third_field"/>
            <input type="text" id="fourth_field"/>
            <input type="text" id="fifth_field"/>
            <input type="text" id="sixth_field"/>
          </fieldset>
        </form>
      </div>
    
    </body>
    </html>

    Anyone know a Javascript that can do this?

    Hi,

    add this to the bottom of your HTML document, just before the closing <body> tag.

    Code JavaScript:
    <script type="text/javascript">
      var els = ["first_field", "fourth_field", "sixth_field"]
      for (var i = 0; i < els.length; i++)
      document.getElementById(els[i]).disabled = true;
    </script>

    This should do what you want.
