移动端页面开发基础和延迟问题

1.移动端的开发中必须要引入 viewport

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">

2.解决移动端点击300ms延迟问题

<script src="https://as.alipayobjects.com/g/component/fastclick/1.0.6/fastclick.js"></script>
<script>
      if ('addEventListener' in document) {
        document.addEventListener('DOMContentLoaded', function() {
          FastClick.attach(document.body);
        }, false);
      }
      if(!window.Promise) {
        document.writeln('<script src="https://as.alipayobjects.com/g/component/es6-promise/3.2.2/es6-promise.min.js"'+'>'+'<'+'/'+'script>');
      }
</script>

这个引进来在chrom谷歌浏览器中双击会报错

所以要加一行css

*{ touch-action: none; }
