百度Ueditor如果config.json中配置的文件管理中的'file'與'video'不是一個目錄，那麽就不能瀏覽已上傳過的視頻；根據文件管理的相關代碼添加了瀏覽在線視頻的功能。

1.修改config.json， 添加視頻相關參數

"videoManagerActionName": "listvideo",
"videoManagerListPath": "static/upload/video/",
"videoManagerUrlPrefix": "http://127.0.0.1:5000/",
"videoManagerListSize": 20,
"videoManagerAllowFiles": [
    ".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
    ".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid"
]

2. 修改lang/zh-cn/zh-ch.js

# 343
'insertvideo':{
        'static':{
            'lang_tab_insertV':"插入視頻",
            'lang_tab_searchV':"搜索視頻",
            'lang_tab_uploadV':"上傳視頻",
            'lang_tab_onlineV':"在線視頻",     // 添加'online'標簽翻譯
            ...
         }
         ...
}

3. 修改dialogs/video/video.css

#online {
    width: 100%;
    height: 336px;
    padding: 10px 0 0 0;
}
#online #videoList{
    width: 100%;
    height: 100%;
    overflow-x: hidden;
    overflow-y: auto;
    position: relative;
}
#online ul {
    display: block;
    list-style: none;
    margin: 0;
    padding: 0;
}
#online li {
    float: left;
    display: block;
    list-style: none;
    padding: 0;
    width: 113px;
    height: 113px;
    margin: 0 0 9px 9px;
    *margin: 0 0 6px 6px;
    background-color: #eee;
    overflow: hidden;
    cursor: pointer;
    position: relative;
}
#online li.clearFloat {
    float: none;
    clear: both;
    display: block;
    width:0;
    height:0;
    margin: 0;
    padding: 0;
}
#online li img {
    cursor: pointer;
}
#online li div.file-wrapper {
    cursor: pointer;
    position: absolute;
    display: block;
    width: 111px;
    height: 111px;
    border: 1px solid #eee;
    background: url("./images/bg.png") repeat;
}
#online li div span.file-title{
    display: block;
    padding: 0 3px;
    margin: 3px 0 0 0;
    font-size: 12px;
    height: 13px;
    color: #555555;
    text-align: center;
    width: 107px;
    white-space: nowrap;
    word-break: break-all;
    overflow: hidden;
    text-overflow: ellipsis;
}
#online li .icon {
    cursor: pointer;
    width: 113px;
    height: 113px;
    position: absolute;
    top: 0;
    left: 0;
    z-index: 2;
    border: 0;
    background-repeat: no-repeat;
}
#online li .icon:hover {
    width: 107px;
    height: 107px;
    border: 3px solid #1094fa;
}
#online li.selected .icon {
    background-image: url(images/success.png);
    background-image: url(images/success.gif) \9;
    background-position: 75px 75px;
}
#online li.selected .icon:hover {
    width: 107px;
    height: 107px;
    border: 3px solid #1094fa;
    background-position: 72px 72px;
}

4. 修改dialogs/video/video.html

<div id="tabHeads" class="tabhead">
    ...
    <span tabSrc="upload" data-content-id="upload"><var id="lang_tab_uploadV"></var></span>
    <span tabSrc="online" data-content-id="online"><var id="lang_tab_onlineV"></var></span>    <!-- 添加'online'的標簽 -->
    ...
</div>
<div id="tabBodys" class="tabbody">
   ...
   <div id="upload" class="panel">
   ...
   </div>
   <div id="online" class="panel">                             <!-- 添加'online'標簽的容器 -->
      <div id="videoList"><var id="lang_imgLoading"></var></div>
   </div>
</div>

5. 修改dialogs/video/video.js

說明：當然，如果上傳的視頻是一個視頻服務器，也就沒必要此功能。
