一段判断是否微信和ie打开的js代码

微信判断代码

<script>
//判断是否微信登陆
function isWeiXin() {
    var ua = window.navigator.userAgent.toLowerCase();
    console.log(ua); 
    //mozilla/5.0 (iphone; cpu iphone os 9_1 like mac os x) applewebkit/601.1.46 (khtml, like gecko)version/9.0 mobile/13b143 safari/601.1
    if (ua.match(/MicroMessenger/i) == 'micromessenger') {
        return true;
    } else {
        return false;
    }
}
if (isWeiXin()) {
    alert(" 请不要使用微信打开，可以复制网址到浏览器打开...")
}
</script>

ie判断代码

<script type="text/javascript">
//判断是否ie
(function (window) {
    var userAgent = navigator.userAgent;
    var isIE = userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1;
    var isIE11 = userAgent.indexOf('Trident') > -1 && userAgent.indexOf("rv:11.0") > -1;
    var isWeixin = userAgent.indexOf('micromessenger') > -1;
    if (isIE || isIE11) {
        alert("请勿使用IE浏览器哦，推荐谷歌、QQ、360等浏览器~");
        window.open("about:blank");
    }
    
    var isWechat = (function () {
        return navigator.userAgent.toLowerCase()
            .indexOf('micromessenger') !== -1
    })();
})(window)
</script>
