document.all[id] vs document.getElementById [id]

[SimonTheSponge]

Could somebody enlighten me to the differences in these functions

My understanding

document.all[id] = IE4+
document.layers[id] = NS5+
document.getElementById [id] = IE5+ and NS6+

if I want to create a crossbrowser script that refers an elememtn in a DIV or Layer Tag is it safer to use the first 2 and ingnore getElementById as I have had problems with this in older browsers

Thanks

My advice is don't try to develop for IE4 and NS4. Both are nearly obsolete and comprise such a small percentage of browser usage that it's not worth the effort. You'll spend 80% of your time developing for less then 5% of the browsers. There's always a better way...
