js判断手机浏览器操作系统及微信浏览器的方法

今天用到的代码，一并奉上。

js判断手机系统并跳转 if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) { //alert(navigator.userAgent); window.location.href ="apple.htm"; } else if (/(Android)/i.test(navigator.userAgent)) { //alert(navigator.userAgent); window.location.href ="android.htm"; }else{ window.location.href ="xxx/tablet.htm"; };

js判断微信浏览器并提示

<script type="text/javascript"> function is_weixin() { var ua = navigator.userAgent.toLowerCase(); if (ua.match(/MicroMessenger/i) == "micromessenger") { return true; } else { return false; } } var isWeixin = is_weixin(); var winHeight = typeof window.innerHeight != 'undefined' ? window.innerHeight : document.documentElement.clientHeight; function loadHtml(){ var div = document.createElement('div'); div.id = 'weixin-tip'; div.innerHTML = '<p><img src="http://photo.101rc.com/weixin/live_weixin.png" alt="微信打开"/></p>'; document.body.appendChild(div); } function loadStyleText(cssText) { var style = document.createElement('style'); style.rel = 'stylesheet'; style.type = 'text/css'; try { style.appendChild(document.createTextNode(cssText)); } catch (e) { style.styleSheet.cssText = cssText; //ie9以下 } var head=document.getElementsByTagName("head")[0]; //head标签之间加上style样式 head.appendChild(style); } var cssText = "#weixin-tip{position: fixed; left:0; top:0; background: rgba(0,0,0,0.8); filter:alpha(opacity=80); width: 100%; height:100%; z-index: 100;} #weixin-tip p{text-align: center; margin-top: 10%; padding:0 5%;}"; if(isWeixin){ loadHtml(); loadStyleText(cssText); } </script>
