Android 4.x 去除输入框的蓝色边框

        var ua = navigator.userAgent.toLowerCase();
        if(ua.match(/android/i)=="android"){
            var android = ua.split(/android/i)[1];
            var version = trim(android.split("\.")[0]);
            if(version >= 4){

                /*目的是解决Android 4.x输入框的问题（其实Android 4.x有BUG）*/
                $("allMain").style.left = "100%";
                

                 /*用CSS3的方法把页面移过来*/

                 $("allMain").style.webkitTransform = 'translate3d(-'+gWidth+'px, 0, 0)';
            }
        }
