List bullet toggle

[Capone]

How can I toggle between bullet and no bullet in an unordered list on a mouseover of the list item?

css:

li{list-style-type:none;}
li{list-style-type:disc;}

li.nothing {list-style-type:none;}
li.a_label {list-style-type:disc;}

Thank you, Fang. As I understand it, your lines would make classes of list items with or without bullets. But how to get to bullets appearing/disappearing on mouseover/mouseout on a single list item?

[Fang]

Initial class should be 'nothing'
onmouseover="this.className='a_label';"
onmouseout="this.className='nothing';"

Thank you. Excellent. Works perfectly.
