funClick = function(btnID,changeClass){
btnID.onclick = function() {
var boxClass = btnID.parentNode.parentNode.className;
var ifClass = boxClass.indexOf(changeClass);
if(ifClass < 0){
boxClass = boxClass + " " + changeClass;
}else {
boxClass = boxClass.replace(changeClass,"");
}
btnID.parentNode.parentNode.className = boxClass;
