屏蔽苹果浏览器对数字的识别Meta标签中的format-detection属性及含义

<meta content="telephone=no" name="format-detection">

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">

CSS判断横屏竖屏

@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。
