讓富文本編輯器支持複製doc中多張圖片直接粘貼上傳

讓富文本編輯器支持複製doc中多張圖片直接粘貼上傳

 

Chrome+IE默認支持粘貼剪切板中的圖片，可是我要發佈的文章存在word裏面，圖片多達數十張，我總不能一張一張複製吧？

我但願打開文檔doc直接複製粘貼到富文本編輯器，直接發佈

感受這個彷佛很困難，由於Ueditor自己不支持，粘貼後直接就是空白，這裏面必定有緣由。

好，開始嘗試UMeditor，Chrome只能得到本地路徑，沒法讀取文件。

https://ueditor.baidu.com/website/umeditor.html（有興趣能夠試試）

 

 

難道就這麼失敗了？

不，可是我意外發現UMeditor居然支持粘貼word中的多張圖片（僅支持IE11，不支持IE10如下版本、以及Chrome等）

切換HTML，會看到你的圖片被組織成base64

nice，機會來了，既然IE支持複製word中的多張圖片直接粘貼base64，既然有了base64咱們就有辦法上傳轉圖片啦！

那麼咱們來改造Ueditor，讓他支持IE11（總比沒得用強吧）

打開你的ueditor.all.js(1.4.3版本如下行號根據本身使用的版本可能不一樣)

1、註釋掉14679行（暫時不明確有什麼不良影響）

//執行默認的處理

//me.filterInputRule(root);

2、在28725行插入如下代碼（若是是使用IE11粘貼會獲得base64，先用佔位符佔位，再逐個把base64專成Blob文件並上傳，上傳完成再替換爲你的img屬性src爲服務器圖片url）

服務端上傳代碼

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);

                   //自動建立目錄

                   if (!Directory.Exists(folder)) Directory.CreateDirectory(folder);

                   HttpPostedFile file = Request.Files.Get(0);

 

                //原始文件名稱，由控件自動生成。               

                string nameOri = file.FileName;

                   string ext = Path.GetExtension(nameOri).ToLower();

 

                   string filePathSvr = Path.Combine(folder, nameOri);

 

                   Response.Write(uploadPath + nameOri);

              }

         }

     }

}

 

處理後的效果，可以批量上傳word中全部的圖片

 

圖片上傳後保存在服務器端

 

3、處理ueditor提供的uploadimage方法

客戶已經使用半年，沒有問題，很是有用，很是方便的功能
