1.实现思路
创建一个xx.txt文件，存放于项目路径下用文件流去读取文件内容并将读取的内容存放到页面的富文本编辑器框内富文本编辑框内容改变后，保存时用文件流的方式保存到xx.txt文件中提示：注意编码问题，否则容易出现中文乱码
2.页面展示
编辑器默认为禁止编辑状态，点击编辑按钮时可编辑内容，编辑完成后，点击保存按钮即可完成。
3.前端代码

js代码：
var editor;$(function(){editor = UE.getEditor('coursecontent',{readonly: true});// setTimeout(() => {// editor.disable();// }, 3000);});//编辑function item_edit(){$('#edit').attr("style","display:none;");$("#save").attr("style","display:block;");editor.enable();}//保存function item_save(){$.ajax({url: basePath + "/company/company_save",data:{words: encodeURI(encodeURI(editor.getContent()))},type: 'post',dataType: 'json',success(result){if(result.code == '1') {dialogMsg('保存成功！', 0);$('#edit').attr("style","display:block;");$("#save").attr("style","display:none;");editor.disable();}else{dialogMsg('保存失败！', 0);}}});}
4.后台代码
