Python3 + Django2.0 百度Ueditor 富文本编辑器的集成
百度富文本编辑器官网地址：http://fex.baidu.com/ueditor/
疑问：为什么要二次集成？
答案：因为百度富文本编辑器Ueditor没有对python的支持
步骤1：
在官网下载Ueditor的任意版本代码：http://ueditor.baidu.com/website/download.html#ueditor
步骤2：
将下载的代码放入到 django 项目中
步骤3：前端引用
在前端HTML代码中引用富文本编辑器【注意：此时因为还没有实例化富文本编辑器，所以暂时无效果！！！】
<!-- 引用对应的js文件 --> <script type="text/javascript" charset="utf-8" src="{% static 'xxx/xxx/ueditor.config.js' %}"></script> <script type="text/javascript" charset="utf-8" src="{% static 'xxx/xxx/ueditor.all.min.js' %}"></script> <!-- 富文本编辑器 --> <div> <script id="uedit" type="text/plain></script> </div>
步骤6：js代码
在前端引用之后，使用js实例化Ueditor，并且配置一些参数：
// 富文本编辑器处理方法 News.prototype.listenEditor = function () { // 实例化一个富文本编辑器 window.ue = UE.getEditor('editor', { 'initialFrameHeight': 400,//设置富文本编辑器的高度 //'serverUrl': '/ueditor/upload/', //设置文件上传的视图函数（服务器路径） /* * initialFrameWidth:"100%"：设置富文本 编辑器自适应宽度 * 也可以在：ueditor.config.js中修改initialFrameWidth 达到同样的目的 */ initialFrameWidth:"100%" }); };
步骤6：军事机密，django + python服务端的集成处理（直接复制就可以用了）
1> views.py 中逻辑代码，还需要在settings进行对应的配置
