自制在线富文本编辑器，精简完整版
一、实现功能，截图如下：
二、用到的技术：
html+css+js+php
主要技术：js
三、项目文件目录：
需要搭建本地服务器，或传到远程服务器上
四、项目源代码如下
Index.php代码如下：
<!DOCTYPE html>
<html lang="en">

五、项目图标
工具条图标：
表情
六、后台接入
七、总结及注意事项
不需要插入图片功能的去掉php代码然后将.php文件改为.html即可变成本地文本编辑器，是不是很酷！当然功能跟world比没那么强大！
需要图片插入功能的注意保存上传图片的文件夹的位置和代码里设置的一致。写的比较快，可能会有不足，各位看官多多谅解！需要帮忙或解惑的可以加我的QQ群：184037581（验证信息写上来自博客园）
