    • 移除HTML5 input在type="number"时的上下小箭头

      • 在chrome下：

          input::-webkit-outer-spin-button,input::-webkit-inner-spin-button{
      -webkit-appearance: none !important;
      margin: 0; 
  }

      • Firefox下：

          input[type="number"]{-moz-appearance:textfield;}

      • 第二种方案：

        • 将type="number"改为type="tel"，同样是数字键盘，但是没有箭头。

    • HTML5手机浏览直接给一个号码打电话，发短信

    <a href="tel:15222222222">移动WEB页面JS一键拨打号码咨询功能</a>
<a href="sms:15222222222">移动WEB页面JS一键发送短信咨询功能</a>
<!--移动web页面自动探测电话号码-->
<meta name="format-detection" content="telephone=no">
<meta http-equiv="x-rim-auto-match" content="none">
    @media screen and (orientation: portrait) {
  /*竖屏 css*/
} 
@media screen and (orientation: landscape) {
  /*横屏 css*/
}
    //判断手机横竖屏状态：
window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", function() {
        if (window.orientation === 180 || window.orientation === 0) { 
            alert('竖屏状态！');
        } 
        if (window.orientation === 90 || window.orientation === -90 ){ 
            alert('横屏状态！');
        }  
    }, false); 
//移动端的浏览器一般都支持window.orientation这个参数，通过这个参数可以判断出手机是处在横屏还是竖屏状态。
