Using return !count++ in a onClick event enables to disable a link, but how to know if it's clicked for the 1st,2nd,3rd times ?....

onclick="if(!count++) return true;else { alert(count+' clicks'); return 
false; }"
So, the variable count will tell you how many times it's been clicked, 
after the ++ line has been run.
(The if statement takes advantage of the postfix operator's feature of 
returning the value of the variable BEFORE it's incremented.  Remaining 
code sees count with it's value AFTER it's incremented.)
