Place one "var objA;" before the loop then remove the "var" inside.
Redeclaring a variable is a bad practice that will bite you in other
languages.

It's doing its job, it's alerting the value of intI, which is what you left
it. The easiest solution is to add a custom property to the object to hold
the current value of intI:

objA.currentI = intI;
objA.onclick = function(){ alert( this.currentI ); };
