week兼容性不好

datetime兼容性不好,推荐用datetime-local

time用来设置时间(小时和分钟);

month用来设置年和月;

date用来设置年月日;

datetime用来设置年月日和时间;

    email:="email" name="email"br    url:="url"="url"    tel:="tel"="tel"    number:="number"    date:="date"="date"    month:="month"="month"    week:="week"="week"    time:="time"="time"    datetime:="datetime"="datetime"    datetime-local:="datetime-local"="datetime-local"    range:="range" min="1"="10"    search:="search"="search"    color:="color"="color">>
