Hi  All,

Is it possible to run a javascript funtion without assigning it to an event? for example, conditionally in an if statement as in the example below.

If somevariable = somevalue then

call javascriptfunction()

else

continue page

End if

or does anyone know of an alternative way to automatically run some javascript based on a condition.

Thanks in advance,
Nev.

You can do this:

<body onLoad="<% if x=something then%>javascriptfunction()<%end if%>" >

If you can tie to the onload event, use f_t_b's example ^^^.  Otherwise, it's messy, but you can directly output the javascript:

<%
IF some_condition THEN
   response.write("<script language='JavaScript'>")
   response.write("var x=" & x & ";")
   (continue jscript)
   response.write("</script>")
ELSE
   (do other stuff)
END IF
%>

Frodman has that right:

consider the following:

<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
<TITLE></TITLE>
</HEAD>
<BODY>

<P>&nbsp;</P>
<SCRIPT LANGUAGE=javascript>
<!--
alert("hi");
//-->
</SCRIPT>

</BODY>
</HTML>


So, we know that works (try it!). The next step then would be:

<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
<TITLE></TITLE>
</HEAD>
<BODY>
<%if someCondition then%>
<SCRIPT LANGUAGE=javascript>
<!--
alert("hi");
//-->
</SCRIPT>
<%end if%>
</BODY>
</HTML>
