Ueditor中支持音频

Ueditor中支持音频

作者: DK_S | 来源:发表于2018-04-17 16:41 被阅读0次

已有不少小伙伴给出了Ueditor中拓展支持插入音频功能的方法,但还是存在一些特例性的问题。踩完数个坑后总算把音频功能基本搞顺畅,这里整理汇总留个记录,以防年长健忘。

1. 修改ueditor.config.js文件,增加插入音频功能入口:

(1)在toolbars中增加'insertaudio'

toolbars: [[
    'source', '|', 'undo', 'redo', '|',
    ...
    'simpleupload',  'insertimage',  'emotion', 'insertaudio', 'insertvideo', 
    '|',
    'horizontal', 'date', 'time', 'spechars', '|', 'wordimage'
]]

(2)在labelMap中增加'insertaudio'对应的提示文字

labelMap: {
    'anchor' : '', 
    'vaecolor' : '自定义字体颜色',
    'insertaudio' : '音频',
}

2. 修改ueditor.all.js文件,增加插入音频页面和命令入口:

(1)在iframeUrlMap中增加插入音频页面的路径

var iframeUrlMap = {
    ...
    'insertaudio':'~/dialogs/audio/audio.html',
    'insertvideo':'~/dialogs/video/video.html',
    ...
    };

(2)在btnCmds中增加点击插入音频触发的命令

var btnCmds = ['undo', 'redo', 'formatmatch',
    ...
    'insertaudio'];

(3)在dialogBtns的ok属性中增加插入音频对话框

var dialogBtns = {
    noOk: ['searchreplace', 'help', 'spechars', 'webapp','preview'],
    ok: ['attachment', 'anchor', 'link', 'insertimage', 'map', 'gmap', 
        ...
        'insertaudio', 'vaecolor']
};

3. 增加audio.html:

(1)在ueditor/dialogs目录下增加audio目录,并增加audio.html,实现点击插入音频按钮时弹出的插入音频页面(此处可根据自身业务需求参照video.html或image.html来实现)

注:此页面中提供了插入音频和上传音频两种方式,现只实现了上传音频的功能。插入音频相对比较简单,不详述

<!doctype html>
<html>
<head>
    <meta charset="UTF-8">
    <title>音频对话框</title>

                    <div class="row">
                        <label for="url"><var id="lang_input_url"></var></label>

                    </div>
                    <div class="row">
                        <label><var id="lang_input_title"></var></label>
                        <span><input class="text" type="text" id="title"/></span>
                    </div>
                </div>
                <div class="right"><div id="preview"></div></div>
            </div>

            <!-- 上传音频 -->
            <div id="upload" class="panel focus">
                <div class="titleBar">
                    <label>标题</label>
                    <input type="text" class="uploadAudioTitle"/>
                </div>
                <div id="queueList" class="queueList">
                    <div class="statusBar element-invisible">
                        <div class="progress">
                            <span class="text">0%</span>
                            <span class="percentage"></span>
                        </div><div class="info"></div>
                        <div class="btns">
                            <div id="filePickerBtn"></div>
                            <div class="uploadBtn"><var id="lang_start_upload"></var></div>
                        </div>
                    </div>
                    <div id="dndArea" class="placeholder">
                        <div class="filePickerContainer">
                            <div id="filePickerReady"></div>
                        </div>
                    </div>
                    <ul class="filelist element-invisible">
                        <li id="filePickerBlock" class="filePickerBlock"></li>
                    </ul>
                </div>
            </div>
        </div>
    </div>
    <script type="text/javascript" src="audio.js"></script>
</body>
</html>

(2)增加audio.css用以实现audio.html中的相关样式(此处可照搬video.css或image.css后对应修改下)

/* 上传音频 */
.tabbody #upload.panel {
    width: 0;
    height: 0;
    overflow: hidden;
    position: absolute !important;
    clip: rect(1px, 1px, 1px, 1px);
    background: #fff;
    display: block;
}

.tabbody #upload.panel.focus {
    width: 100%;
    height: 300px;
    display: block;
    clip: auto;
}

#upload .titleBar {
    width: 100%;
    margin: 10px;
    font-size: 14px;
}

#upload .titleBar .uploadAudioTitle {
    margin-left: 5px;
    width: 88%;
}

// 后面省略,照搬后修改即可
...

(3)增加audio.js用以实现audio.html中的上传音频、插入音频代码等操作(同样的,照搬vedio.js或image.js后对应修改即可)

注:涉及到几个特例化的地方:①音频上传至服务器或云存储,改造过图片上传的应该驾轻就熟了;②因要求给插入的音频配上标题,此处上传为单个音频文件上传,故要禁用多选批量上传;③开始上传、暂停上传、取消上传的相应功能;④最终insertList的结构,要传递给ueditor.all.js中的insertaudio命令以向编辑器内插入音频控件代码

(function () {

    var insertaudio,
        uploadaudio;
    // 音频文件key前缀
    var keyPrefix = editor.getOpt('keyPrefix') + '/audio';
    
    window.onload = function () {
        initTabs();
        initButtons();
    };

    /* 初始化tab标签 */
    function initTabs() {
        var tabs = $G('tabhead').children;
        var audio = editor.selection.getRange().getClosedNode();
        var id = tabs[0].getAttribute('data-content-id');
        for (var i = 0; i < tabs.length; i++) {
            domUtils.on(tabs[i], "click", function (e) {
                var j, bodyId, target = e.target || e.srcElement;
                id = target.getAttribute('data-content-id');
                for (j = 0; j < tabs.length; j++) {
                    bodyId = tabs[j].getAttribute('data-content-id');
                    if(tabs[j] == target){
                        domUtils.addClass(tabs[j], 'focus');
                        domUtils.addClass($G(bodyId), 'focus');
                    }else {
                        domUtils.removeClasses(tabs[j], 'focus');
                        domUtils.removeClasses($G(bodyId), 'focus');
                    }
                }
            });
        }
        switch (id) {
        case 'remote':  // 插入音频/远程音频(预留)
            insertaudio = insertaudio || new RemoteAudio();
            break;
        case 'upload':  // 上传音频(主要)
            uploadaudio = uploadaudio || new UploadAudio('queueList');
            break;
        }
    }

    /* 初始化onok事件 */
    function initButtons() {
        dialog.onok = function () {
            var remote = false, list = [], id, tabs = $G('tabhead').children;
            for (var i = 0; i < tabs.length; i++) {
                if (domUtils.hasClass(tabs[i], 'focus')) {
                    id = tabs[i].getAttribute('data-content-id');
                    break;
                }
            }
            switch (id) {
                case 'remote':
                    list = insertaudio.getInsertList();
                    break;
                case 'upload':
                    list = uploadaudio.getInsertList();
                    var count = uploadaudio.getQueueCount();
                    if (count) {
                        $('.info', '#queueList').html('<span style="color:red;">' + '还有2个未上传文件'.replace(/[\d]/, count) + '</span>');
                        return false;
                    }
                    
                    // 配上标题
                    var title = $('.uploadAudioTitle').val();
                    if (!title || $.trim(title) == '') {

                        return false;
                    }
                    if(list) {
                        for(var i = 0; i < list.length; i++) {
                            var f = list[i];
                            f['title'] = title;

                        }
                    }
                    break;
            }
            
            if(list) {
                editor.execCommand('insertaudio', list);
                remote && editor.fireEvent("catchRemoteAudio");
            }
        };
    }

    /* 上传音频 */

            uploader.on('uploadError', function (file, code) {

            }
            return list;
        }
    };

})();

(4)修改ueditor.css文件,增加插入音频按钮图标及页面窗口的相关样式:

.edui-default  .edui-for-insertaudio .edui-icon {
    background-position: -320px -20px;
}

/*audio-dialog*/
.edui-default .edui-for-insertaudio .edui-dialog-content {
    width: 590px;
    height: 390px;
}

/* audio*/
.edui-default  .edui-for-insertaudio .edui-icon {
    background-image: url(../images/audio.png) !important;
}

音频按钮图标放在ueditor目录的themes/default/images下。

(5)修改zh-cn.js文件,增加insertaudio的相关配置(类同insertvideo):

'insertaudio' : {
        'static' : {
            'lang_tab_remote' : "插入音频",
            'lang_tab_upload' : "上传音频",
        },
        'uploadSelectFile' : '点击选择音频文件',
        'uploadAddFile' : '继续添加',
        'uploadStart' : '开始上传',
        'uploadPause' : '暂停上传',
        'uploadContinue' : '继续上传',
        'uploadCancel' : '取消上传',
        'uploadRetry' : '重试上传',
        'uploadDelete' : '删除',
        'uploadTurnLeft' : '向左旋转',
        'uploadTurnRight' : '向右旋转',
        'uploadPreview' : '预览中',
        'uploadNoPreview' : '不能预览',
        'updateStatusReady' : '选中_个音频文件,共_KB。',
        'updateStatusConfirm' : '已成功上传_个音频文件,_个音频文件上传失败',
        'updateStatusFinish' : '共_个(_KB),_个上传成功',
        'updateStatusError' : ',_个音频文件上传失败。',
        'errorNotSupport' : 'WebUploader 不支持您的浏览器!如果你使用的是IE浏览器,请尝试升级 flash 播放器。',
        'errorLoadConfig' : '后端配置项没有正常加载,上传插件不能正常使用!',
        'errorExceedSize' : '文件大小超出',
        'errorFileType' : '文件格式不允许',
        'errorInterrupt' : '文件传输中断',
        'errorUploadRetry' : '上传失败,请重试',
        'errorHttp' : 'http请求错误',
        'errorServerUpload' : '服务器返回出错',
        'remoteLockError' : "宽高不正确,不能所定比例",
        'numError' : "请输入正确的长度或者宽度值!例如:123,400",
        'audioUrlError' : "不允许的音频格式或者图片域!",
        'audioLoadError' : "音频加载失败!请检查链接地址或网络状态!",
        'searchRemind' : "请输入搜索关键词",
        'searchLoading' : "音频加载中,请稍后……",
        'searchRetry' : " :( ,抱歉,没有找到音频!请重试一次!"
    },

(6)修改config.json文件,增加音频上传的相关配置

/* 上传音频配置项 */
"audioActionName": "uploadaudio", /* 执行上传音频的action名称 */
"audioFieldName": "file", /* 提交的音频表单名称 */
"audioMaxSize": 30720000, /* 上传大小限制,单位B */
"audioAllowFiles": [".mp3", ".wma", ".wav", ".amr"], /* 上传音频格式限制 */
"audioUrlPrefix": "http://audio.ushallnotpass.com/" /* 音频访问路径前缀 */

4. 修改ueditor.all.js文件,增加audio插件

<audio>标签自带样式不太好看,此处audio插件对插入的音频控件样式进行了改造,并实现了相关的播放控制事件。感谢Dandelion_drq

5. 解决ueditor复制粘贴冲突

上述几个步骤完成后,插入音频功能就已实现了。但在编辑器中插入音频后再粘贴其他内容时,会发现音频控件的进度条样式出了问题。这是因为ueditor在粘贴后会对空内容div进行删除,而audio插件所插入的音频控件中有空内容div。可修改相应方法将音频控件中的div排除。

在ueditor.all.js中找到filter(div)方法,再找到以下这段代码:

if (browser.webkit) {
    var br = root.lastChild();
    if (br && br.type == 'element' && br.tagName == 'br') {
        root.removeChild(br)
    }
    utils.each(me.body.querySelectorAll('div'), function (node) {
        if (domUtils.isEmptyBlock(node)) {
            domUtils.remove(node,true)
        }
    })
 }

对删除div的判定条件进行修改,排除音频控件的相关div:

if (domUtils.isEmptyBlock(node) && node.className != 'progress-bar-bg' && node.className != 'progressBar') {
    domUtils.remove(node,true)
 }

6. 文章页面音频控件初始化

在ueditor中编辑完文章内容之后,在展示文章时也需要对文章内容中的音频控件进行初始化,故需要提供相应的初始化方法供页面调用。实现方式比较简单,和audio插件中的方法基本一致,不详述。

另若需支持移动端的访问,则需要对点击、滑动等事件进行区分处理,对PC端访问要响应mouse事件,对移动端访问要响应touch事件:

// 定义不同端事件调用
var hasTouch = 'ontouchstart' in window,
startEvent = hasTouch ? 'touchstart' : 'mousedown',
moveEvent = hasTouch ? 'touchmove' : 'mousemove',
endEvent = hasTouch ? 'touchend' : 'mouseup',
cancelEvent = hasTouch ? 'touchcancel' : 'mouseup';
