function onGet(){
var val = Cookie.get(name);
if (val){
$('content').value='查询结果：' + val;
}else{
$('content').value='查询结果：未设置或过期';
}
}
function onSet(){
Cookie.set(name, value, {duration: 1}); //duration的值为天数，默认365，0为浏览器进程结束后过期
$('content').value='Cookie已设置';
}
function onRemove(){
Cookie.remove(name);
$('content').value='Cookie已清除';
}
