i need a javascript function to be called on certain button click, upon that click the button name will change.
ie,

<input type=button id = button1 value=boy onclick=function(boy,girl)>

i need the javascript function to take 2 parameters and check if the value of the button is the first paramter, then the value will become the 2nd and vice versa.

so if i press the button and it says BOY, it will become Girl
and if i press the button and it says Girl it will become boy!
using javascript please thx.

    There are many ways to do this, but by getById function showed below you will have a portable function to access to DOM elements by id :

    <html>
    <script type="text/javascript">

        function getById(a) {
           if (document.getElementById && document.getElementById(a)) {
              return document.getElementById(a)
           } else {
              if (document.all && document.all(a)) {
                 return document.all(a)
              } else {
                 if (document.layers && document.layers[a]) {
                    return document.layers[a]
                 } else {
                    return false
                 }
              }
           }
        }
        function myfunc()
        {
        getById("button1").value =(getById("button1").value=="boy")?"girl":"boy";
        }
    </script>
<head>
</head>
<input type="button" value="boy" id="button1" onclick="myfunc();" />
</html>
