Hi All!

Just thought that It would be a nice idea to expose this new function, and get your comments and improvments...

code:

<html>

<head>

<title>Function Append!</title>

</head>

<script language="JavaScript">

<!--

  function appendFunction(from_fnc, to_fnc)

  {

    function parseFunctionName(fnc)

    {

      str = String(fnc);

      return str.substr(str.indexOf("function ") + 8, str.indexOf("(") - 8 - (document.layers ? 1 : 0)); // 8 = length("function ");

    }

    fnc = new Function(

                       "function F_A() {\n" + 

                            to_fnc + "\n" + 

                            parseFunctionName(to_fnc)+ "();\n" + 

                          "}\n" + 

                       "function F_B() {\n" + 

                            from_fnc + "\n" + 

                            parseFunctionName(from_fnc)+ "();\n" + 

                          "}\n" + 

                       "F_A(); F_B();"

                      );

    return fnc;

  }

//-->

</script>



<body onload="alert('body loaded');">

<script language="JavaScript">

<!--

  x = appendFunction(new Function("alert('a');"), new Function("alert('b');"));

  alert('now appending all to the window.onload');

  x = appendFunction(x, window.onload);

  window.onload = x;

//-->

</script>

</body>

</html>

so...
x = appendFunction(new Function("alert('a');"), new Function("alert('b');"));
will append the first function to the second one, and they will be called as: function2(); function1();

Is there is any simple way to append two functions?

Well, not really. But just making a new function like

function twofunc()
{
funcone();
functwo();
}

does the trick fine. Nonetheless, it's an interesting peice of code.
