Selecting a Specific Option

mike

I need to be able to select a specific option in a select list. This is
what I have:
<select name="mysel">
<option value=""></option>
<option value="1">First </option>
<option value="2" selected>First</option>
<option value="3">First </option>
</select>

But I want to select the first option. Here is my code:

var frm_objs = document.report .elements;
for ( j=0; j<frm_objs.leng th; j++ )
{
if ( frm_objs[j].type=='select-one' )
{
if ( frm_objs[j].name=='mysel' )
{
frm_objs[j].options[0].selected=true;
}
}
}

I think is should select the first ooption but it does not. The default
option 2 remains selected.

Any help is apreciated.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
