1、引入Js <script src="/webPage/pcPage/AppMarketManager/js/wangEditor.js"></script>(只需要下载一个js文件即可)
2、使用建议参考官方文档
3、修改源码实现本地上传视频功能
a、源码
function Video(editor) { this.editor = editor; this.$elem = $(‘<div class="w-e-menu"><i class="w-e-icon-play"></i></div>‘); this.type = ‘panel‘; // 当前是否 active 状态 this._active = false; } // 原型 Video.prototype = { constructor: Video, onClick: function onClick() { this._createPanel(); }, _createPanel: function _createPanel() { var _this = this; // 创建 id var textValId = getRandom(‘text-val‘); var btnId = getRandom(‘btn‘); // 创建 panel var panel = new Panel(this, { width: 350, // 一个 panel 多个 tab tabs: [{ // 标题 title: ‘插入视频‘, // 模板 tpl: ‘<div><input id="‘ + textValId + ‘" type="text" class="block" placeholder="u683Cu5F0Fu5982uFF1A<iframe src=... ></iframe>"/><div class="w-e-button-container"><button id="‘ + btnId + ‘" class="right">u63D2u5165</button></div></div>‘, // 事件绑定 events: [{ selector: ‘#‘ + btnId, type: ‘click‘, fn: function fn() { var $text = $(‘#‘ + textValId); var val = $text.val().trim(); if (val) _this._insert(val); // 插入视频 // 返回 true,表示该事件执行完之后,panel 要关闭。否则 panel 不会关闭 return true; } }] }] // tabs end }); // panel end // 显示 panel panel.show(); // 记录属性 this.panel = panel; } // 插入视频 _insert: function _insert(val) { var editor = this.editor; editor.cmd.do(‘inserthtml‘, val + ‘<p><br></p>‘); } }
b、实现文件上传 ,图片上传在UploadImg中uploadImg方法中实现,参考一下,在UploadImg中添加一个uploadVideo方法
// 上传视频 UploadImg.prototype.uploadVideo=function uploadVideo(files) { var _this3 = this; if (!files || !files.length) { return; } // ------------------------------ 获取配置信息 ------------------------------ var editor = this.editor; var config = editor.config; var uploadVideoServer = config.uploadVideoServer; var maxSize = config.uploadVideoMaxSize; var maxSizeM = maxSize / 1024 / 1024; var maxLength = config.uploadVideoMaxLength || 10000; var uploadFileName = config.uploadFileName || ‘‘; var uploadVideoParams = config.uploadVideoParams || {}; var uploadVideoParamsWithUrl = config.uploadVideoParamsWithUrl; var uploadVideoHeaders = config.uploadVideoHeaders || {}; var hooks = config.uploadVideoHooks || {}; var timeout = config.uploadVideoTimeout || 30 * 60 * 1000; // 30分钟 var withCredentials = config.withCredentials; if (withCredentials == null) { withCredentials = false; } var customUploadVideo = config.customUploadVideo; if (!customUploadVideo) { // 没有 customUploadVideo 的情况下,需要如下两个配置才能继续进行图片上传 if (!uploadVideoServer) { return; } } // ------------------------------ 验证文件信息 ------------------------------ var resultFiles = []; var errInfo = []; arrForEach(files, function (file) { var name = file.name; var size = file.size; // chrome 低版本 name === undefined if (!name || !size) { return; } if (/.(pdf|rm|rmvb|3gp|avi|mpeg|mpg|mkv|dat|asf|wmv|flv|mov|mp4|ogg|ogm)$/i.test(name) === false) { // 后缀名不合法,不是视频 errInfo.push(‘u3010‘ + name + ‘u3011u4E0Du662Fu56FEu7247‘); return; } if (maxSize < size) { // 上传视频过大 errInfo.push(‘u3010‘ + name + ‘u3011u5927u4E8E ‘ + maxSizeM + ‘M‘); return; } // 验证通过的加入结果列表 resultFiles.push(file); }); // 抛出验证信息 if (errInfo.length) { this._alert(‘视频验证未通过: ‘ + errInfo.join(‘ ‘)); return; } if (resultFiles.length > maxLength) { this._alert(‘一次最多上传‘ + maxLength + ‘个视频‘); return; } // ------------------------------ 自定义上传 ------------------------------ if (customUploadVideo && typeof customUploadVideo === ‘function‘) { customUploadVideo(resultFiles, this.insertLinkVideo.bind(this)); // 阻止以下代码执行 return; } // 添加图片数据 var formdata = new FormData(); arrForEach(resultFiles, function (file) { var name = uploadFileName || file.name; formdata.append(name, file); }); // ------------------------------ 上传图片 ------------------------------ if (uploadVideoServer && typeof uploadVideoServer === ‘string‘) { // 添加参数 var uploadVideoServerArr = uploadVideoServer.split(‘#‘); uploadVideoServer = uploadVideoServerArr[0]; var uploadVideoServerHash = uploadVideoServerArr[1] || ‘‘; objForEach(uploadVideoParams, function (key, val) { // 因使用者反应,自定义参数不能默认 encode ,由 v3.1.1 版本开始注释掉 // val = encodeURIComponent(val) // 第一,将参数拼接到 url 中 if (uploadVideoParamsWithUrl) { if (uploadVideoServer.indexOf(‘?‘) > 0) { uploadVideoServer += ‘&‘; } else { uploadVideoServer += ‘?‘; } uploadVideoServer = uploadVideoServer + key + ‘=‘ + val; } // 第二,将参数添加到 formdata 中 formdata.append(key, val); }); if (uploadVideoServerHash) { uploadVideoServer += ‘#‘ + uploadVideoServerHash; } // 定义 xhr var xhr = new XMLHttpRequest(); xhr.open(‘POST‘, uploadVideoServer); // 设置超时 xhr.timeout = timeout; xhr.ontimeout = function () { // hook - timeout if (hooks.timeout && typeof hooks.timeout === ‘function‘) { hooks.timeout(xhr, editor); } _this3._alert(‘上传视频超时‘); }; // 监控 progress if (xhr.upload) { xhr.upload.onprogress = function (e) { var percent = void 0; // 进度条 var progressBar = new Progress(editor); if (e.lengthComputable) { percent = e.loaded / e.total; progressBar.show(percent); } }; } // 返回数据 xhr.onreadystatechange = function () { var result = void 0; if (xhr.readyState === 4) { if (xhr.status < 200 || xhr.status >= 300) { // hook - error if (hooks.error && typeof hooks.error === ‘function‘) { hooks.error(xhr, editor); } // xhr 返回状态错误 _this3._alert(‘上传视频发生错误‘, ‘u4E0Au4F20u56FEu7247u53D1u751Fu9519u8BEFuFF0Cu670Du52A1u5668u8FD4u56DEu72B6u6001u662F ‘ + xhr.status); return; } result = xhr.responseText; if ((typeof result === ‘undefined‘ ? ‘undefined‘ : _typeof(result)) !== ‘object‘) { try { result = JSON.parse(result); } catch (ex) { // hook - fail if (hooks.fail && typeof hooks.fail === ‘function‘) { hooks.fail(xhr, editor, result); } _this3._alert(‘上传视频失败‘, ‘上传视频返回结果错误,返回结果是: ‘ + result); return; } } if (!hooks.customInsert && result.errno != ‘0‘) { // hook - fail if (hooks.fail && typeof hooks.fail === ‘function‘) { hooks.fail(xhr, editor, result); } // 数据错误 _this3._alert(‘上传视频失败‘, ‘上传视频返回结果错误,返回结果 errno=‘ + result.errno); } else { if (hooks.customInsert && typeof hooks.customInsert === ‘function‘) { // 使用者自定义插入方法 hooks.customInsert(_this3.insertLinkVideo.bind(_this3), result, editor); } else { // 将图片插入编辑器 var data = result.data || []; data.forEach(function (link) { _this3.insertLinkVideo(link); }); } // hook - success if (hooks.success && typeof hooks.success === ‘function‘) { hooks.success(xhr, editor, result); } } } }; // hook - before if (hooks.before && typeof hooks.before === ‘function‘) { var beforeResult = hooks.before(xhr, editor, resultFiles); if (beforeResult && (typeof beforeResult === ‘undefined‘ ? ‘undefined‘ : _typeof(beforeResult)) === ‘object‘) { if (beforeResult.prevent) { // 如果返回的结果是 {prevent: true, msg: ‘xxxx‘} 则表示用户放弃上传 this._alert(beforeResult.msg); return; } } } // 自定义 headers objForEach(uploadVideoHeaders, function (key, val) { xhr.setRequestHeader(key, val); }); // 跨域传 cookie xhr.withCredentials = withCredentials; // 发送请求 xhr.send(formdata); } }
c、插入编辑器(插入视频也写在UploadImg.prototype中)
// 根据链接插入视频 insertLinkVideo: function insertLinkVideo(link) { if (!link) return; var _this2 = this; var editor = this.editor; var config = editor.config; // 校验格式 var linkVideoCheck = config.linkVideoCheck; var checkResult = void 0; if (linkVideoCheck && typeof linkVideoCheck === ‘function‘) { checkResult = linkVideoCheck(link); if (typeof checkResult === ‘string‘) { // 校验失败,提示信息 alert(checkResult); return; } } editor.cmd.do(‘insertHTML‘, ‘<iframe src="‘ + link + ‘" style="width:650px;height: 366px" frameborder="0"></iframe>‘); }
d、添加视频上传的默认参数(在config中添加一些上传视频默认参数, 加不加无所谓,在使用方法中都做了参数判断,为了规范代码,这里添加一下。)
// 是否显示添加网络视频的 tab showLinkVideo: true, // 插入网络视频的回调 linkVideoCallback: function linkVideoCallback(url) { // console.log(url) // url 即插入视频的地址 }, // 默认上传视频 max size: 512M uploadVideoMaxSize: 512 * 1024 * 1024, // 配置一次最多上传几个视频 uploadVideoMaxLength: 5, // 上传视频的自定义参数 uploadVideoParams: { // token: ‘abcdef12345‘ }, // 上传视频的自定义header uploadVideoHeaders: { // ‘Accept‘: ‘text/x-json‘ }, // 自定义上传视频超时时间 30分钟 uploadVideoTimeout: 30 * 60 * 1000, // 上传视频 hook uploadVideoHooks: { // customInsert: function (insertLinkVideo, result, editor) { // console.log(‘customInsert‘) // // 视频上传并返回结果,自定义插入视频的事件,而不是编辑器自动插入视频 // const data = result.data1 || [] // data.forEach(link => { // insertLinkVideo(link) // }) // }, before: function before(xhr, editor, files) { // 视频上传之前触发 // 如果返回的结果是 {prevent: true, msg: ‘xxxx‘} 则表示用户放弃上传 // return { // prevent: true, // msg: ‘放弃上传‘ // } }, success: function success(xhr, editor, result) { // 视频上传并返回结果,视频插入成功之后触发 }, fail: function fail(xhr, editor, result) { // 视频上传并返回结果,但视频插入错误时触发 }, error: function error(xhr, editor) { // 视频上传出错时触发 }, timeout: function timeout(xhr, editor) { // 视频上传超时时触发 } }
e、使用(初始化编辑器,配置上传视频参数)
var editor = new window.wangEditor(‘#text-editor‘); // 图片上传 editor.customConfig.uploadImgServer = ‘upload/editUpload‘; // 上传接口 editor.customConfig.uploadFileName = ‘files‘; // 上传文件参数名 editor.customConfig.uploadImgHooks = { // 上传完成处理方法 customInsert: function (insertImg, result) { if (result.ret === 200) { (result.data || ‘‘).split(‘,‘).forEach(function (link) { link && insertImg(link); }); } else { flavrShowByTime(‘上传失败‘, null, ‘danger‘); } } }; // 视频上传 editor.customConfig.uploadVideoServer = ‘editUpload‘; // 上传接口 editor.customConfig.uploadVideoHooks = { // 上传完成处理方法 customInsert: function (insertVideo, result) { if (result.ret === 200) { (result.data || ‘‘).split(‘,‘).forEach(function (link) { link && insertVideo(link); }); } else { flavrShowByTime(‘上传失败‘, null, ‘danger‘); } } }; editor.create();
