mouseevent - Increase Javascript Mouse Events - i know if there way increment sample rate of mousemove events of js. when cross window around 10-20 events, not plenty purpose of app, when can reach +100; thanks in advance, i think, maybe i'm wrong, mousemove events "sample rate" not determined javascript, sample rate of mouse. means whenever mouse sends event browser, event fired (if mouse has moved of @ to the lowest degree 1 pixel) , can respond it. mouse higher sample rates create more events (and more precise), mouse lower sample rate create fewer events. why when play quake 4 sample rate of mouse affects precision of aiming. so don't think it's problem of javascript, , should have app respond accordingly events generated mouse. same thing done in first person shooter auto aiming option. javascript mouseevent

[\s\s]* seems more used, perhaps because it's more portable. regex
