Django 项目试炼blog(9) -- 文本编辑器的使用(文件存储,预览)
HTML
<div class="col-md-9"> <div> <p class="text-center" style="background-color: #e5eef7;font-size: 18px" >添加文章</p> <form action="" method="post" style="margin-top: 40px"> {% csrf_token %} <label for="title">文章标题</label> <input type="text" id="title" class="form-control" name="title"> <div style="margin-top: 10px"> <label for="">内容</label> <div> <textarea id="editor_id" name="content" style="width:900px;height:400px;" ></textarea> </div> </div> <input type="submit" class="btn btn-info " value="提交文章" style="margin-top: 10px"> </form> </div> </div>
Jquery

from bs4 import BeautifulSoup @login_required def add_article(request): data = get_data(request.user.username) if request.method=='POST': title=request.POST.get('title') content = request.POST.get("content")

重点
1、在jquery中文本编辑器(kindeditor)的引入,与初始化
2、后端文件存储位置,拼接。
3、前端文本编辑器上传后,的预览功能。(后端传送的地址非文件地址,而是前端可以直接访问文件的URL)
4、利用bs4对纯属内容进行过滤(前端纯属到后端的内容是带标签样式名的),通过bs4过滤切割,过滤掉数据中的标签名
