$(".button").click(function () {
var id = $(this).attr("id");
if (id == "next") {
$("#prev").removeClass("disabled");
if ( child >= length ) {
$(this).addClass("disabled");
$("#submit").removeClass("disabled");
} else if ( child <= length ) {
child++;
}
} else if(id == "prev") {
}
});
this is a shorthand, but I am confused here what is this pointing at?
Is it the clicked button element or the section?
