为date类型的input设置默认值为当前时间

<input type="date" id="date" placeholder="请选择日期"/>

 $(document).ready(function () {var date= new Date();var day = ("0" + date.getDate()).slice(-2);var month = ("0" + (date.getMonth() + 1)).slice(-2);var today= date.getFullYear() + "-" + (month) + "-" + (day);$('#date').val(today);})
