Question

Netscape 4.0 won't reference onchange(this.value) in a form select box.

Asked by: tandy

Hi,

I can't seem to get Netscape 4.0 to recognize a simple reference to a select box selections value property.

I tried all kinds of methods, even explict references but
it returns a JavaScript Error box with the message 'null'. When I try the different references in iexplorer 5.0, all is well and my reference is returned properly.


here is the code I am using:

<html>
<head>

<TITLE>Image Slideshow</TITLE>
     <SCRIPT LANGUAGE="JAVASCRIPT" TYPE="TEXT/JAVASCRIPT">
     <!-- Hide script from old browsers


</script>


</head>
<body>





<FORM NAME="myform">
<INPUT NAME="messages" TYPE=TEXT SIZE=25 VALUE="Slide Show Messages">

<SELECT  TYPE=TEXT NAME="slideChoice" onchange="alert(window.document.myform.slideChoice.value)">
               <OPTION VALUE="none" SELECTED>Select Slide Show</OPTION>
               
                        <OPTION VALUE="Bowling">Bowling</OPTION>
               <OPTION VALUE="Basketball">Basketball</OPTION>
               <OPTION VALUE="Fair Play">Fair Play</OPTION>
               <OPTION VALUE="Floor Hockey">Floor Hockey</OPTION>
        </SELECT>

</FORM>

</body>
</html>

Is there another way to reference the value object that both versions will recognize?

I tried "alert(this.value)" and again iexplorer returned the value and Netsacpe shows null. Am I missing something here..

Tandy,
  Netscape 4.x is a pain when it comes to getting the select box selected item value.  But, there is a solution.

I recommend the following:

In your onChange event call a javascript function:
onChange="myfunction()"

then inside myfunction have this:

----Begin Example----
myfunction()
{
 x = document.myform.slideChoice.options[document.myform.slideChoice.selectedIndex].value;
 alert(x);
 return false;
}
----End Example----

I hope this helps you out.

Mike Metzger
