    Replicate textbox value

    Hi.

    I have a form with some textboxes in it. When a user clicks a button,
    I need to verify if only one of the textboxes if filled and if so, I
    need to replicate the value of this textbox to all other textboxes on
    the form. If two or more textboxes are filled I don't need to do the
    replication. How can I do that?

    Thanks,

    Robert Scheer

      Re: Replicate textbox value

      Here is sample code to do that:

      <html>
      <head>
      <script language="JavaS cript" type="text/javascript">
      <!--
      function checkForm1(call erValue){
      if (howManyFilled( ) == 1)
      fillAll(callerV alue)
      }

      function fillAll(value){
      for (var i=0; i < document.forms['form1'].elements.lengt h; i++){
      document.forms['form1'].elements[i].value = value;
      }
      }

      function howManyFilled() {
      var howmany = 0;
      for (var i=0; i < document.forms['form1'].elements.lengt h; i++){
      if (document.forms['form1'].elements[i].value == "")
      continue
      howmany++
      }
      return (howmany);
      }
      //-->
      </script>
      </head>

      <body>
      <form name="form1">
      <input type="text" name="textbox1" onchange="check Form1(this.valu e)"><br>
      <input type="text" name="textbox2" onchange="check Form1(this.valu e)"><br>
      <input type="text" name="textbox3" onchange="check Form1(this.valu e)"><br>
      <input type="text" name="textbox4" onchange="check Form1(this.valu e)"><br>
      <input type="text" name="textbox5" onchange="check Form1(this.valu e)"><br>
      <input type="text" name="textbox6" onchange="check Form1(this.valu e)"><br>
      <input type="text" name="textbox7" onchange="check Form1(this.valu e)"><br>
      <input type="text" name="textbox8" onchange="check Form1(this.valu e)"><br>
      </form>
      </body>
      </html>
