(部分机型不适用)解决ios10及以上Safari双击和双指缩放无法禁止的问题

<script>/*禁止ios缩放，双击和双指*/window.onload=function () {document.addEventListener('touchstart',function (event) {if(event.touches.length>1){event.preventDefault();}});var lastTouchEnd=0;document.addEventListener('touchend',function (event) {var now=(new Date()).getTime();if(now-lastTouchEnd<=300){event.preventDefault();}lastTouchEnd=now;},false);document.addEventListener('gesturestart', function (event) {event.preventDefault();});};</script>

直接贴上代码就行
