This is how to do it. I know I could have made a plugin but im lazy right now.
$("element"
).each(
function(index, value) {
var textToLower = $(this).text();
$(this).text(textToLower.toLowerCase());
}
);
$("element").each(
function(index, value) {
var textToLower = $(this).text();
$(this).text(textToLower.toUpperCase());
}
);
