alert("It works&quot

}

i want to be able to store the name in a variable

var temporary = test

and be able to call the function

can I do this - does anyone have any syntax

Thanks in advance

store the function name in a string and then execute it using the eval() function

Code:

<HTML>
<HEAD>
<TITLE>Test</TITLE>
<SCRIPT LANGUAGE=JavaScript>

var blah = &quot;test()&quot;;

function test() {
   alert (&quot;blah&quot;);
}

</SCRIPT>
<BODY>
<FORM NAME=&quot;blahForm&quot;>
<INPUT TYPE=BUTTON VALUE=BLAH ONCLICK='javascript:eval(blah);'
</FORM>
</BODY>
</HTML>

I forgot to close my button tag above.... not that it probably matters for your program

Code:

<INPUT TYPE=BUTTON VALUE=BLAH ONCLICK='javascript:eval(blah);'>

you can also do something like this:

Code:

function foo() {
	alert(&quot;foo&quot;);
}

var bar = foo;

bar();
bar();
bar();
