标签:scale   time   body   button   view   else   java   alt   div   

最近要做一个活动,需要用倒计时,写好之后再IOS上无效,经过百度知道了,原来IOS不能识别格式“2017-11-09 ……”,所以要进行转换才有效

直接上代码了:

<body>
    <textarea name="" id="txt1" cols="30" rows="10"></textarea>
    <textarea name="" id="txt2" cols="30" rows="10"></textarea>


    <button id="time_btn">测试倒计时</button>
    <div id="timelayer" class="timelayer">
        <div class="con">
            <h4>离活动开始还有</h4>
