禁用微信字體縮放功能

僅僅安卓機禁用縮放功能

 var u = navigator.userAgent, app = navigator.appVersion;
            var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1; //g
            var isIOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios終端
            if (isAndroid) {
                    if (typeof WeixinJSBridge == "object" && typeof WeixinJSBridge.invoke == "function") {
                    handleFontSize();
                } else {
                    if (document.addEventListener) {
                        document.addEventListener("WeixinJSBridgeReady", handleFontSize, false);
                    } else if (document.attachEvent) {
                        document.attachEvent("WeixinJSBridgeReady", handleFontSize);
                        document.attachEvent("onWeixinJSBridgeReady", handleFontSize);  }
                }
                function handleFontSize() {
                    // 設置網頁字體爲默認大小
                    WeixinJSBridge.invoke('setFontSizeCallback', { 'fontSize' : 0 });
                    // 重寫設置網頁字體大小的事件
                    WeixinJSBridge.on('menu:setfont', function() {
                        WeixinJSBridge.invoke('setFontSizeCallback', { 'fontSize' : 0 });
                    });
                }
            }

全部機型禁用縮放功能

   if (typeof WeixinJSBridge == "object" && typeof WeixinJSBridge.invoke == "function") {
                    handleFontSize();
                } else {
                    if (document.addEventListener) {
                        document.addEventListener("WeixinJSBridgeReady", handleFontSize, false);
                    } else if (document.attachEvent) {
                        document.attachEvent("WeixinJSBridgeReady", handleFontSize);
                        document.attachEvent("onWeixinJSBridgeReady", handleFontSize);  }
                }
                function handleFontSize() {
                    // 設置網頁字體爲默認大小
                    WeixinJSBridge.invoke('setFontSizeCallback', { 'fontSize' : 0 });
                    // 重寫設置網頁字體大小的事件
                    WeixinJSBridge.on('menu:setfont', function() {
                        WeixinJSBridge.invoke('setFontSizeCallback', { 'fontSize' : 0 });
                    });
