text: Title: 建议添加ios浏览器input禁止缩放的代码~
  Body: 1. ios端，点击数量或者输入邮箱时，会放大，会出现难看的滚动条~
  
  2. 解决方法，input的字体，调为16px，然后添加<meta>和Js，我自己调整的如下：
  
  <script>
  // 禁用缩放
     function addMeta() {
     $('head').append('<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />');} setTimeout(addMeta, 3000);
    
   // 禁用双指放大
    document.documentElement.addEventListener('touchstart', function (event) {
     if (event.touches.length > 1) {
     event.preventDefault();
    } }, {
     passive: false
     });
  
   // 禁用双击放大
   var lastTouchEnd = 0;
   document.documentElement.addEventListener('touchend', function (event) {
   var now = Date.now();
   if (now - lastTouchEnd <= 300) {
   event.preventDefault(); }
   lastTouchEnd = now; }, {passive: false });
  </script>
  
  <style>
  input{font-size:16px !important}
  </style>
