How to get SELECT value with getElementById

robulator · Sep 21, 2001

I'm trying to extract the selected value from a SELECT element using getElementById() so that it will be compatible with IE and NS 6. It works fine in NS 6, but not in IE 5.5. No value is returned in IE. Does anyone know if it can be made to work in both browsers? By the way, getElementsByTagName doesn't work in IE with the SELECT element either.

Thanks for help

Perhaps you could give some sample code. I think some browsers allow selectObj.value, whereas others need selectObj.options[ selectObj.selectedIndex ].value.

Here's some code:
<HTML>
<BODY>

<SCRIPT>
function ShowWell() {
alert(document.getElementById("Location&quot

.NSSelect.value)
}
</SCRIPT>

<FORM NAME="Location" ID="Location">
<SELECT ID="NSSelect" NAME="NSSelect" SIZE=1>
<OPTION SELECTED> NORTH
<OPTION> SOUTH
</SELECT><BR>

<INPUT TYPE="BUTTON" VALUE="Select" onclick="ShowWell()">
</FORM>
</BODY>
</HTML>

As a variation you can try document.getElementById("NSSelect&quot

.value, but neither work in IE.

OK. I've got it. In IE you must define the VALUE attribute in the SELECT tag, but this is not necessary in NS6.
