Looping though multiple fields - misnamed as [Javascript] Named Layers in IE

[javascript@xxxxxxxxxx (TomMallard)]

Correct, you have to add the tests for those cases and handle them
separately.

if(typeOf(document.Form1.MyField[i]) != 'object'){
    ...there are 0 or 1 so use name...
    if(document.Form1.MyField.name == 'someName'){
        var strName = document.Form1.MyField.value;
    }
}else{
    var arrMyField = document.Form1.MyField;
    if(arrMyField.length>0){
        for(i=0;i<arrMyField.length;i++){
            ...process arrMyField[i].name...
        }
    }
}
