Domino JavaScript combobox validation

Domino, JavaScript, Validation

I would like to ask if someone has a JavaScript code which does the validation on a combobox field. If nothing is selected, a warning pops up and reminds the user that a value has to be selected. I tried to use this code which works fine on regular text fields:

if (document.forms[0].AppName.value == "")
{
alert("You have not selected an application. Please select an application and then continue.");
document.forms[0].AppName.focus();
return false;
}

I would appreciate it if I can get any help on this.

The value property is directly exposed on single select boxes in IE, but the proper syntax is:

document.forms[0].selectBox.options[document.forms[0].selectBox.selectedIndex].value. You have to access the value as an index of the options collection.
