nodejs+express+mysql 之 简单的在线HTML编辑器

<script src="/kindeditor/kindeditor-min.js" type="text/javascript"></script> --- 这里是第一步的文件路径，如果不是按照上一步做的，你需要修改此引用路径
<form style="padding-top:10px;padding-left:5%;">
    <textarea name="content" style="width:90%;height:500px;visibility:hidden;"></textarea>
  </form>
  <p>
    <input type="button" name="getHtml" onclick="getHtml();" value="取得HTML" />
    <input type="button" name="setHtml" onclick="setHtml();" value="设置HTML" />
  </p>
<script type="text/javascript">
  var _editor;
  $(function(){
    KindEditor.ready(function(K) {
      _editor = K.create('textarea[name="content"]', {
        pasteType : 2,
        items : [
          'source', '|','formatblock','fontname', 'fontsize', '|', 'forecolor','lineheight', 'bold', 'italic', 'underline',
          'removeformat', '|', 'justifyleft', 'justifycenter', 'justifyright', 'insertorderedlist',
          'insertunorderedlist', '|', 'emoticons', 'image', 'link','code','insertfile','clearhtml', 'quickformat','preview']//这里可自定义显示的功能
      });
    });
  });

  function getHtml(){
    console.log(_editor.html());
  }
</script>

app.get('/editor',function (req, res){ 
	res.render('editor', { layout:'layout/gray'});//这里指定显示的模板，若是默认的话，去掉就行
});

		uploadJson = K.undef(self.uploadJson, self.basePath + 'php/upload_json.php'),//将php....该为上传之后要执行的代码，我这里改为了upload

if (formatUploadUrl) {
	url = K.formatUrl(url, 'absolute');//将这里改成url = window.location.origin + '/'+url;，因为图片路径在同一个文件夹下
}

app.post('/kindeditor/upload',function (req,res){

4.完成上传文件的功能
