Quick way to use checkbox to show/hide a div

The following code illustrates a simple show/hide feature, based on status of a checkbox.  The checkbox calls it onClick.

myShowHideFunc = function(obj){
 var displayMode = (obj.checked)?"none":"inline";
 var focusobj = $("#DivToToggle");
 $(focusobj).css({'display':displayMode});
}

I draw your attention to the displayMode variable which is set by the if-then switch to a language that the jQuery css command can understand.
