概述:
百度Ueditor如果config.json中配置的文件管理中的'file'与'video'不是一个目录,那么就不能浏览已上传过的视频;根据文件管理的相关代码添加了浏览在线视频的功能。
1.修改config.json, 添加视频相关参数
"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;
}
#online .pagination {
margin-bottom: 10px;
margin-right: 10px;
display: inline-block;
float: right;
}
#online .pagebtn {
display: inline;
border-radius: 4px;
padding: 2px;
cursor: default;
text-align: center;
color: #495060;
background: url("../image/images/bg.png") no-repeat 0 -30px;
}
3. 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'的标签 -->
...
</div>
<div id="tabBodys" class="tabbody">
...
<div id="upload" class="panel">
...
</div>
<div id="online" class="panel"> <!-- 添加'online'标签的容器 -->
<div id="videoList"><var id="lang_imgLoading"></var></div>
</div>
</div>
4. 修改dialogs/video/video.js
var video = {},
...
uploadFile,
onlineFile;
window.onload = function(){
...
initOnline();
...
}
function addOkListener(){
...
case "online":

break;

height: 280,
align: "none"
})
});
editor.execCommand('insertvideo',videoObjs, 'upload');
}
function initOnline(){

}

/* 添加视频到列表界面上 */
pushData: function (list) {

说明:当然,如果上传的视频是一个视频服务器,也就没必要此功能。
