微信限制内置浏览器的访问方法

<script type="text/javascript">
    // 对浏览器的UserAgent进行正则匹配，不含有微信独有标识的则为其他浏览器
    var useragent = navigator.userAgent;
    if (useragent.match(/MicroMessenger/i) != ‘MicroMessenger‘) {
        // 这里警告框会阻塞当前页面继续加载
        alert(‘已禁止本次访问：您必须使用微信内置浏览器访问本页面！‘);
        // 以下代码是用javascript强行关闭当前页面
        var opened = window.open(‘about:blank‘, ‘_self‘);
        opened.opener = null;
        opened.close();
    }
</script>

function onBridgeReady(){
 WeixinJSBridge.call(‘hideOptionMenu‘);
}

if (typeof WeixinJSBridge == "undefined"){
    if( document.addEventListener ){
        document.addEventListener(‘WeixinJSBridgeReady‘, onBridgeReady, false);
    }else if (document.attachEvent){
