Why do you need this? If you need client side checks, why use server side controls?
If you really need it, use Developer tools to see exactly what renders on your page and find the value you need like this:
$("#<%=dlstZone.CliendID %> a:active") or maybe :selected or, if it isn't a but input[type="checkbox"] etc...

Because its an existing work and I can't change the layout... i can only develop a chart based on this data list click... i have already built a chart using a radio button list yesterday, now I have another chart which is formed from a datalist click...

Well, the same logic applies. Same way you grabbed radio button value, you can grab datalist value, selector will depend on particular element, but the basic grab is the same.

If you can alter itemtemplate you could use OnClientClick property to call javascript function to do what you need to do. Don't forget to return false if you don't want default handler to trigger
