    Cut & Paste

    I use these two functions for Copy & Paste with buttons in some text area
    into a form:

    <SCRIPT LANGUAGE="Javas cript">

    function copy(area){
    var temp = eval("document. " + area);
    aa=temp;
    window.clipboar dData.setData(' Text',aa);
    }

    function paste(area2){
    var temp2 = eval("document. " + area2);
    bb=window.clipb oardData.getDat a('Text');
    temp2 = bb;
    }
    </SCRIPT>
    </head>


    If i call the Copy function (dinamically with php) with a parameter like:
    form1.text1.val ue it works fine, but with the Paste function doesn't work.
    I think the problem is in the evaluate statement of the parameter area2.

    Anyone can help me ?? Thanks

      Try this:

      <div id=from>qwerty</div>
      =============== ============
      <div id=to>asdfg</div>

      <script type="text/javascript">

      function copy(area){
      var temp = document.getEle mentById(area);
      window.clipboar dData.setData(' Text',temp.inne rHTML);
      }

      function paste(area){
      var temp = document.getEle mentById(area);
      temp.innerHTML = window.clipboar dData.getData(' Text');
      }

      copy("from")
      paste("to")


      </script>

      Tested IE6

          Wow... where do I start?

          1. Do not use LANGUAGE. Instead, use TYPE
          2. Do not use eval(). There are always better ways to do it
          3. Dont make so many temp variables. It makes it hard to read
          4. clipboardData only works in IE 5+. I dont know if anything like this
          exists in other browsers.

          Try something more like this. Of course, modify it for a better set of
          what you need, but this should give you a good start.
