1、附件上传
需求:
在编辑器中上传word,pdf,excel等附件后,能根据上传附件的名称生成link链接,在展示页面能实现点击链接下载或预览附件,效果图如下:
实现方法:
quill编辑器自身带有link,但不满足需求,于是我修改了原有的link方法,使其适配目前的需求
1.增加el-upload上传组件
<el-upload :action="uploadUrl" :before-upload="handleBeforeUploadFile" :on-success="handleUploadSuccessFile" :on-error="handleUploadErrorFile" name="file" :show-file-list="false" :headers="headers" style="display: none" ref="uploadFile" v-if="this.type == 'url'" > </el-upload>
复制
2.重写link方法
// 源码中是import直接倒入,这里要用Quill.import引入 const Link = Quill.import("formats/link"); // 自定义a链接 class FileBlot extends Link { // 继承Link Blot static create (value) { let node = undefined; if (value && !value.href) { // 适应原本的Link Blot node = super.create(value) } else { // 自定义Link Blot node = super.create(value.href) node.href = value.href node.innerText = value.innerText // node.setAttribute('download', value.innerText); // 左键点击即下载 } return node; } } FileBlot.blotName = "link" // 这里不用改,如果需要也可以保留原来的,这里用个新的blot FileBlot.tagName = "A" Quill.register(FileBlot) // 注册link
复制
3.给link生成的超链接按钮添加点击事件
toolbar.addHandler("link", (value) => { if (value) { debugger console.log('this.$refs.upload',this.$refs.upload) this.$refs.uploadFile.$children[0].$refs.input.click(); } else { this.quill.format("link", false); } });
复制
4.添加upload的on-success、on-error方法
handleUploadSuccessFile(res, file) { // 如果上传成功 if (res.code == 200) { // 获取富文本组件实例 let quill = this.Quill; // 获取光标所在位置 let length = quill.getSelection().index; // 插入文件 res.url为服务器返回的图片地址 quill.insertEmbed(length, "link", { href: process.env.VUE_APP_BASE_API + res.fileName, innerText: res.originalFilename }, ); // 调整光标到最后 quill.setSelection(length + 1); } else { this.$message.error("文件插入失败"); } }, handleUploadErrorFile() { this.$message.error("文件插入失败"); },
