Thinkphp5框架中引入Markdown编辑器操作示例

本文实例讲述了thinkphp5框架中引入markdown编辑器操作。分享给大家供大家参考，具体如下：

编辑器下载地址以及演示:

1.把下载的项目放在public目录下

2.页面中引入jquery.js，editormd.js，editormd.css

demo

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>markdown测试</title>
  <link rel="stylesheet" href="/public/markdown/css/editormd.css" rel="external nofollow" />
  <script src="__js__/jquery.min.js"></script>
  <script src="/public/markdown/editormd.js"></script>
</head>
<body>
  <form action="{:url('test')}" enctype="multipart/form-data" method='post'>
    <div id="content-editormd" class="form-group">
      <textarea style="display:none;" class="form-control" id="content-editormd-markdown-doc" name="content-editormd-markdown-doc"></textarea>
    </div>
    <button>提交</button>
  </form>
<script type="text/javascript">
  $(function() {
    editormd("content-editormd", {
      placeholder : '编辑你的内容...',
      width  : "100%",
      height : 1000,
      syncscrolling : "single",
      path  : "/public/markdown/lib/",
      watch  : true,
      previewtheme : "white",//预览
      theme : 'white',//工具栏
      savehtmltotextarea : true, // 保存html到textarea
      // 图片上传
      imageupload : true,
      imageformats: ["jpg","jpeg","gif","png","bmp","webp"],
      imageuploadurl: "/api/upload/markdownupload",
        toolbaricons : function() { //自定义工具栏，后面有详细介绍
     return editormd.toolbarmodes['full']; // full, simple, mini
   },
    });
  });
//上传
/*
{
  success : 0 | 1,      // 0 表示上传失败，1 表示上传成功
  message : "提示的信息，上传成功或上传失败及错误信息等。",
  url   : "图片地址"    // 上传成功时才返回
}
*/
</script>
</body>
</html>

上传图片

  public function markdownupload(){
    $config = [
      'size' => 2097152,
      'ext' => 'jpg,gif,png,bmp'
    ];
 
    $file = $this->request->file('editormd-image-file');
    $upload_path = str_replace('\\', '/', root_path . 'public/uploads');
    $save_path  = '/uploads/';
    $info    = $file->validate($config)->move($upload_path);
    if ($info) {
      $result = [
        'success' => 1,
        'message' => '上传成功',
        'url'  => str_replace('\\', '/', '/public/'.$save_path . $info->getsavename())
      ];
    } else {
      $result = [
        'success'  => 0,
        'message' => $file->geterror(),
        'url'  => str_replace('\\', '/', '/public/'.$save_path . $info->getsavename())
      ];
    }
    return json($result);
  }

3.页面加载markdown格式内容

<!doctype html>
<html lang="en">
<head>
 <meta charset="utf-8">
 <title>页面加载markdown格式内容</title>
 <link href="/public/markdown/css/editormd.min.css" rel="external nofollow" rel="external nofollow" rel="stylesheet" />
 <script src="__js__/jquery.min.js"></script>
 <script src="/public/markdown/lib/marked.min.js"></script>
 <script src="/public/markdown/lib/prettify.min.js"></script>
 <script src="/public/markdown/lib/raphael.min.js"></script>
 <script src="/public/markdown/lib/underscore.min.js"></script>
 <script src="/public/markdown/lib/sequence-diagram.min.js"></script>
 <script src="/public/markdown/lib/flowchart.min.js"></script>
 <script src="/public/markdown/lib/jquery.flowchart.min.js"></script>
 <script src="/public/markdown/editormd.js"></script>
</head>
<body>
 <div id="doc-content">
 <textarea style="display:none;">
```php
 &lt;?php
 
 echo 1;
 ?&gt;
```
</textarea>
</div>
 
<script type="text/javascript">
  var testeditor;
  $(function () {
    testeditor = editormd.markdowntohtml("doc-content", {//注意：这里是上面div的id
      htmldecode: "style,script,iframe",
      emoji: true,
      tasklist: true,
      tocm: true,
      tex: true, // 默认不解析
      flowchart: true, // 默认不解析
      sequencediagram: true, // 默认不解析
      codefold: true
    });});
 
</script>
</body>
</html>

4.直接展示html格式的内容

<!doctype html>
<html lang="en">
<head>
 <meta charset="utf-8">
 <title>前端显示</title>
 <link href="/public/markdown/css/editormd.min.css" rel="external nofollow" rel="external nofollow" rel="stylesheet" />
 <script src="__js__/jquery.min.js"></script>
 <script src="/public/markdown/lib/marked.min.js"></script>
 <script src="/public/markdown/lib/prettify.min.js"></script>
 <script src="/public/markdown/editormd.min.js"></script>
 
</head>
<body>
 <div id="doc-content">
 {:htmlspecialchars_decode($data)}
 </div>
<script type="text/javascript">
  $(function () {
    editormd.markdowntohtml("doc-content");
  })
</script>
</body>
</html>
