How do you check to see if a Javascript function exists within a page. Need to know if it's there before I call it!!

Hi.
An example:
<html>
<Script Language="JavaScript">
function newWin()
{
var strm="mmde\"fggrgr";
alert(strm);
}
</Script>
<body>
kekfergregreg
<input type=button value="KKKK" onclick="newWin()">
<input type=button value="check" onclick="javascript : try { isTrue() }catch(Exception){alert('Not valid!'); }">
</body>
</html>
The check button call an invalid method.
regards, Kirilla

this works for me:
function func()
{
alert('bob');
}
if(typeof(func) != "undefined"
{
func();
} luciddream@subdimension.com
function func()
{
alert('bob');
}
if(typeof(func) != "undefined"
{
func();
} luciddream@subdimension.com
