The Option
tag has a javascript attribute defaultSelected
that's set to true
if the option had a selected
value on page load. Note that this is the option
tag and not the select
one, so you'll have to loop through the options and check for the attribute.
Something like
var DAccess;
var AccessSelect = document.forms[UIDF]["Access"];
for (var i = 0 ; i<AccessSelect.length ; i++)
{
if (AccessSelect[i].defaultSelected)
DAccess = AccessSelect[i].value;
}
Or, more to the point:
var AccessHasChanged = false;
var AccessSelect = document.forms[UIDF]["Access"];
for (var i = 0 ; i<AccessSelect.length ; i++)
{
if (AccessSelect[i].defaultSelected &&
AccessSelect.value != AccessSelect[i].value)
AccessHasChanged = true;
}
