<body>
  <input type="button" value="调用原生">
  <script>
    // h5调用ios
    document.querySelector('input').onclick = function(){
      window.webkit.messageHandlers.useNative.postMessage('ty')
    }
    // 修改背景色
    function changeBackgroundCOlor(){
      document.body.style.backgroundColor = 'hotpink';
      document.body.innerHTML = '我是ty，你好！'
    }
  </script>
</body>
</html>

url scheme 基本用法

代码演示

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width,user-scalable=no,initial-scale=1.0,maximum-scale=1,0,minimum-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=dege"/>
  <title>Document</title>
</head>
<body>
  <input type="button" value="调用原生">
  <input type="button" class="url" value="通过 url scheme方式交互">
  <script>

    document.querySelector('.url').onclick = function(){
      const iframe = document.createElement('iframe')
      iframe.src = 'heima://click';
      iframe.style.height = 0;
      iframe.style.width = 0;
      document.body.appendChild(iframe);
      document.body.removeChild(iframe);
    }
    // h5调用ios
    document.querySelector('input').onclick = function(){
      window.webkit.messageHandlers.useNative.postMessage('ty')
    }
    // 修改背景色
    function changeBackgroundCOlor(){
      document.body.style.backgroundColor = 'hotpink';
      document.body.innerHTML = '我是ty，你好！'
    }
  </script>
</body>
</html>

混合app开发框架

页面适配

有关1px的边框的问题

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width,user-scalable=no,initial-scale=1.0,maximum-scale=1,0,minimum-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=dege"/>
  <title>界面适配</title>
</head>
<style>
  div{
    height:100px;
  }
  .border-top{
    border-top:1px solid black;
  }
  .border-bottom{
    border-bottom:1px solid black;
  }

  @media screen and (-webkit-min-device-pixel-ratio:2){
    .border-bottom{
      position:relative;
      border-bottom:0;
    }
    .border-bottom:before{
      position:absolute;
      right:0;
      bottom:0;
      left:0;
      height:1px;
      content:'';
      transform:scaleY(0.5);
      background-color: black;
    }
  }
</style>
<body>
  <div class="border-top border-bottom"></div>

</body>
</html>
