今天小編給大家分享一下vue項(xiàng)目怎么實(shí)現(xiàn)前端預(yù)覽word與pdf格式文件的相關(guān)知識(shí)點(diǎn)，內(nèi)容詳細(xì)，邏輯清晰，相信大部分人都還太了解這方面的知識(shí)，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。
頁(yè)面上傳pdf文件效果如下：
頁(yè)面預(yù)覽pdf文件效果如下：
頁(yè)面上傳word文件效果如下：
頁(yè)面預(yù)覽word文件效果如下：
這里先從上傳組件頁(yè)面說起，上傳頁(yè)面組件完整代碼如下，按鈕里面v-show=“$checkPermission([‘Register_tuotpUpload’])“都是給這個(gè)按鈕設(shè)置了按鈕權(quán)限的，我們只需要關(guān)注上傳那一部分的代碼即可，我們用了el-upload組件實(shí)現(xiàn)的手動(dòng)上傳，由于需求要求只能上傳word和pdf，所以能看到屬性設(shè)置的有 accept=”.pdf, .doc, .docx”，然后不展示上傳成功的文件的列表設(shè)置的屬性有:show-file-list=“false”，而handleExceed回調(diào)函數(shù)和limit都是為了限制只能上傳一個(gè)文件，上傳前的回調(diào)鉤子函數(shù)beforeAvatarUpload里進(jìn)行了文件類型判斷與提醒，手動(dòng)上傳是通過UploadFile里進(jìn)行完成的，需要注意的是由于docx-preview這個(gè)插件只能預(yù)覽后綴為docx的word文件，如果是doc后綴格式的word文件一定要讓后端強(qiáng)制將上傳doc格式的文件改為docx格式，目前對(duì)于doc格式的word文件實(shí)現(xiàn)網(wǎng)頁(yè)在線預(yù)覽我只想到了docx-preview這個(gè)插件和這個(gè)解決辦法：

preview() {
console.log("預(yù)覽", this.fileList, this.tuopuForm);
if (!this.fileList) {
this.$message.error(
"拓?fù)鋱D文件為空不能預(yù)覽,請(qǐng)先上傳拓?fù)鋱D文件后再預(yù)覽",
6000
);
return false;
}
this.$router.push({
path: "TuotpPreview",
query: {
fileName: this.tuopuForm.fileName,
fileUrl: this.tuopuForm.fileUrl
}
});
}再來看預(yù)覽頁(yè)面，也就是TuotpPreview.vue組件。word預(yù)覽比較簡(jiǎn)單，先通過命令cnpm i docx-preview --save安裝插件docx-preview，需要注意的是這個(gè)插件只能預(yù)覽后綴為docx的word文件，如果是doc后綴格式的word文件一定要讓后端強(qiáng)制將上傳doc格式的文件改為docx格式，然后當(dāng)前頁(yè)面組件就直接import { defaultOptions, renderAsync } from “docx-preview”;引入，最后在data里進(jìn)行docxOptions配置，然后在頁(yè)面上 要顯示的div上綁定一個(gè) id="bodyContainer"的，因?yàn)橄旅嬉ㄟ^document.getElementById來獲取dom并操作dom，最后調(diào)用renderAsync方法即可。
cnpm i docx-preview --save //安裝word預(yù)覽插件docx-preview
import { defaultOptions, renderAsync } from "docx-preview"; //引入docx-preview插件對(duì)應(yīng)的方法
docxOptions: {
className: "kaimo-docx-666", // string：默認(rèn)和文檔樣式類的類名/前綴

},pdf文件的預(yù)覽是通過獲取到blob文件流之后，直接通過window.open打開新窗口，通過瀏覽器就能預(yù)覽pdf，還有一種就是我現(xiàn)在的這種需求，要在頁(yè)面上預(yù)覽pdf，那就需要通過iframe,然后把blob流對(duì)應(yīng)的src地址賦值回顯即可。完整代碼如下：
