Can you make a model of your situation ? that could help.
What do you want to do exactly? to show/hide many tds when a checkbox
is clicked? and changeBg(), that's for creating a zebra-like striping
of the cells ?
First of all, if you want to show ALL the cells in a table, or a row,
you can just toggle the table or the row. That's surely faster. Maybe
this helps...
function myToggleShow( checkbox, targets ){
targets = $(targets);
$(checkbox).click( function() {
if ( this.checked ){
targets.show('slow');
changeBg(); //is really neccesary to call this EVERY time you
click the checkbox?
} else {
targets.hide('slow');
}
}).triggerHandler('click');
}
myToggleDisplay('#myCheckboxID', 'td.areaToShow');
