[電腦知識]備份FB聊天室訊息

Step 1.  使用 Google Chrome Web Browser

Step 2.  https://m.facebook.com/messages/

Step 3.  點入欲備份那個人的聊天室

Step 4.  按下 Ctrl+Shift+J (Windows/Linux) 或 Cmd+Opt+J (Mac) 進入 Console

Step 5.  複製下面代碼並貼上到上述彈出的視窗

         var id =
         setInterval(function () { document.getElementById('see_older')
                    .getElementsByClassName('content')[0].click(); }, 500);

Step 6.  （可略）等到全部的訊息都載入完成之後鍵入 clearInterval(id)

Step 7.  Ctrl+S 或 Cmd+S 儲存成 HTML 檔案
             Ctrl+P 或 Cmd+P 匯出成 PDF  檔案

步驟7如果游標指到Console會無法成功儲存(變成Console指令)
要在右側對話框的區塊按Ctrl+S或是Ctrl+P..或是簡單一點滑鼠右鍵選擇另存(Html)或列印即可


To start, use a computer and open the google chrome browser. If you don’t have google chrome, then download it. Then use the google chrome browser to go to http://m.facebook.com/messages/

Then click the person you want to see the first message with. Now press “Ctrl + Shift + J” and then paste this code into the lower window that pops up, and then press enter. It will then proceed to load old messages until it reaches the very first message. Here is the code:


setInterval(function () {
document.getElementById('see_older')
.getElementsByClassName('content')[0].click();
}, 500); 


Now once it loads everything, you have two options. You can right click anywhere on the page and choose “save as” and then save that file somewhere on your computer. Then use google chrome to open it when you want to view it later (won’t look right in internet explorer). This will save the entire chat, complete with pictures and emoticons. When you want to search for a particular day, press “Ctrl + F” to bring up the find box. Then type in “Mar 2”, for example, to bring up the conversation on March 2nd.
