让富文本编辑器支持复制doc中多张图片直接粘贴上传
Chrome+IE默认支持粘贴剪切板中的图片,但是我要发布的文章存在word里面,图片多达数十张,我总不能一张一张复制吧?
我希望打开文档doc直接复制粘贴到富文本编辑器,直接发布
感觉这个似乎很困难,因为Ueditor本身不支持,粘贴后直接就是空白,这里面一定有原因。
好,开始尝试UMeditor,Chrome只能获得本地路径,无法读取文件。
https://ueditor.baidu.com/website/umeditor.html(有兴趣可以试试)
难道就这么失败了?
不,但是我意外发现UMeditor竟然支持粘贴word中的多张图片(仅支持IE11,不支持IE10以下版本、以及Chrome等)
切换HTML,会看到你的图片被组织成base64
nice,机会来了,既然IE支持复制word中的多张图片直接粘贴base64,既然有了base64我们就有办法上传转图片啦!
那么我们来改造Ueditor,让他支持IE11(总比没得用强吧)
打开你的ueditor.all.js(1.4.3版本以下行号根据自己使用的版本可能不同)
1、注释掉14679行(暂时不明确有什么不良影响)
//执行默认的处理
//me.filterInputRule(root);
2、在28725行插入以下代码(如果是使用IE11粘贴会得到base64,先用占位符占位,再逐个把base64专成Blob文件并上传,上传完成再替换为你的img属性src为服务器图片url)

服务端上传代码
using System;
using System.Web;
using System.IO;
namespace WordPasterCK4
{
publicpartialclassupload : System.Web.UI.Page
{
protectedvoid Page_Load(object sender, EventArgs e)
{
string fname = Request.Form["UserName"];
int len = Request.ContentLength;
if (Request.Files.Count > 0)
{
DateTime timeNow = DateTime.Now;
string uploadPath = "/upload/" + timeNow.ToString("yyyyMM") + "/" + timeNow.ToString("dd") + "/";
string folder = Server.MapPath(uploadPath);
//自动创建目录
if (!Directory.Exists(folder)) Directory.CreateDirectory(folder);
HttpPostedFile file = Request.Files.Get(0);
//原始文件名称,由控件自动生成。
string nameOri = file.FileName;
string ext = Path.GetExtension(nameOri).ToLower();
string filePathSvr = Path.Combine(folder, nameOri);
Response.Write(uploadPath + nameOri);
}
}
}
}
处理后的效果,能够批量上传word中所有的图片
图片上传后保存在服务器端
3、处理ueditor提供的uploadimage方法
客户已经使用半年,没有问题,非常有用,非常方便的功能
