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
javascript
<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>
2.重写link方法
javascript
// 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
3.给link生成的超链接按钮添加点击事件
javascript
toolbar.addHandler("link", (value) => {
if (value) {
debugger
console.log('this.$refs.upload',this.$refs.upload)
this.$refs.uploadFile.$children[0].$refs.input.click();
} else {
this.quill.format("link", false);
}
});
4.添加upload的on-success、on-error方法
javascript
handleUploadSuccessFile(res, file) {
// 如果上传成功
if (res.code == 200) {
// 获取富文本组件实例
let quill = this.Quill;
// 获取光标所在位置
let length = quill.getSelection().index;
// 插入文件 res.url为服务器返回的图片地址
quill.insertEmbed(length, "link",
{
href: process.env.VUE_APP_BASE_API + res.fileName,
innerText: res.originalFilename
},
);
// 调整光标到最后
quill.setSelection(length + 1);
} else {
this.$message.error("文件插入失败");
}
},
handleUploadErrorFile() {
this.$message.error("文件插入失败");
},
