Does selectedIndex work in Netscape?

joelwenzel · Jul 30, 2002

This works in IE but not in Netscape

document.forms[0].SelectName.selectedIndex = 12;

In Netscape, I can retreive the value of selectedIndex but I cannot set it.

This works for me in NS4.7
<head>
<script type="text/javascript">
function setList () {
document.forms[0].wl_cars.selectedIndex = 1;
}
</script>
</head>
<body text="#000000" bgcolor="#ffffff" onload="setList();">
<form>
<select name=wl_cars>
<option value="-">-Cars-
<option value=ford>Ford
<option value=chevy>Chevy
</select>
</form>
</body>
[/code] Hope this helps,

This is the script I'm using. I cannot figure out this result and why it doesn't work in netscape

<script language=javascript>
document.forms[0].SelectName.selectedIndex = 13;
//Shows 13 in netscape/ie
alert(document.forms[0].SelectName.selectedIndex);
</script>

<script language=javascript>
//Shows 0 in netscape, 13 in ie
alert(document.forms[0].SelectName.selectedIndex);
</script>

Where are the alerts in relation to the SelectName object and to each other? Hope this helps,

exactly as they are shown. they appear after the <select> tag and within the<body> and <form> tags.

Normally, I find the programmer is to blame for most errors but in this case I think it might be netscape, especially since it works fine in ie

Hmmmm...I tried to simulate what you describe here:

It seems ok in Netscape 4.7, but I don't have any later versions to test with. Both alerts display 1.

Code:

<html>
<head>
<title></title>
<script type=&quot;text/javascript&quot;>

<!--
function doThis() {
  var cars = eval(&quot;document.forms[0].wl_cars&quot;);
  var car = cars.value;
  var colors = eval(&quot;document.forms[0].wl_colors&quot;);
  var color = colors.options[colors.selectedIndex].value;
  if (car == &quot;-&quot; || color == &quot;-&quot;) {
    cars.options[0].selected = true;
    colors.options[0].selected = true;
  }
}
// -->
</script>
</head>
<body text=&quot;#000000&quot; bgcolor=&quot;#ffffff&quot;>
<form>
<select name=wl_cars>
<option value=&quot;-&quot;>-Cars-
<option value=ford>Ford
<option value=chevy>Chevy
</select> &nbsp;&nbsp;
<select name=wl_colors>
<option value=&quot;-&quot;>-Colors-
<option value=red>Red
<option value=blue>Blue
</select>
<br>
<input type=button name=wb_button value=&quot;check me&quot; onclick=&quot;doThis();&quot;>
<script language=javascript>
   document.forms[0].wl_cars.selectedIndex  = 1;
   alert(document.forms[0].wl_cars.selectedIndex);
</script>

<script language=javascript>
   alert(document.forms[0].wl_cars.selectedIndex);
</script>
</form>
</body>
</html>

Hope this helps,

Yup. That's basically what I have for my code.

I tried your code in my version of netscape (6.2) and I got the same error.

Displayed 1 and then 0. I guess that means it's a netscape problem.
