只需在组件的src属性传入pdf的链接就能显示相应的pdf文件。
三、API
Props属性
:src
String/Object
pdf的链接,可以是相对、绝对地址或者是一个pdf的加载任务(后面会讲到);
:page
Number-default:1
需要展示pdf的第几页;
:rotate
Number-default:0
pdf的旋转角度,‘90’的倍数才有效;
Events回调
@password
(updatePassword,reason
)
updatePassword:函数提示需要输入的密码;
reason:提示('NEED_PASSWORD' or 'INCORRECT_PASSWORD');
@progress
Number
pdf的页面的加载进度,Rang[0,1];
@page-loaded
Number
pdf某个页面加载成功回调,number为页面索引值;
@num-pages
Number
监听pdf加载,获取pdf的页数;
@error
Object
pdf加载失败回调;
@link-clicked
Number
单机内部链接时触发;
Public methods公共方法
print(dpi,pageList)
调用浏览器打印功能;
dpi打印的分辨率(100)
pageList需要打印的页面array
Public static methods静态方法
createLoadingTask(src)
这个方法创建一个当前pdf的加载任务,可以作为:src使用或者公开的获取当前pdf的页面总数;
单页pdf展示及api使用
可以进行页数切换、pdf旋转、部分打印、全部打印、显示加密pdf功能;
监听当前页面加载,加载进度;
<template>
<div class="pdf">
<div class="pdf-tab">
class="btn-def btn-pre"
@click.stop="prePage">上一页</div>
class="btn-def btn-next"
@click.stop="nextPage">下一页</div>
class="btn-def"
@click.stop="clock">顺时针</div>
class="btn-def"
@click.stop="counterClock">逆时针</div>
class="btn-def"
@click.stop="pdfPrintAll">全部打印</div>
class="btn-def"
@click.stop="pdfPrint">部分打印</div>
<div>{{pageNum}}/{{pageTotalNum}}</div>
<div>进度:{{loadedRatio}}</div>
<div>页面加载成功: {{curPageNum}}</div>
ref="pdf"
:src="pdfUrl"
:page="pageNum"
:rotate="pageRotate"
@password="password"
@progress="loadedRatio = $event"
@page-loaded="pageLoaded($event)"
@num-pages="pageTotalNum=$event"
@error="pdfError($event)"
@link-clicked="page = $event">
</template>
<script>
import pdf from 'vue-pdf'
export default {
name: 'Pdf',
components:{
data(){
return {
pdfUrl:"http://file.dakawengu.com/file/2018-05-29/20180527-tianfeng.pdf",
pageNum:1,
pageTotalNum:1,
pageRotate:0,
// 加载进度
loadedRatio:0,
curPageNum:0,
mounted: function() {
methods: {
prePage(){
var p = this.pageNum
p = p>1?p-1:this.pageTotalNum
this.pageNum = p
nextPage(){
var p = this.pageNum
p = p<this.pageTotalNum?p+1:1
this.pageNum = p
clock(){
this.pageRotate += 90
counterClock(){
this.pageRotate -= 90
password(updatePassword, reason) {
updatePassword(prompt('password is "123456"'))
console.log('...reason...')
console.log(reason)
console.log('...reason...')
pageLoaded(e){
this.curPageNum = e
pdfError(error){
console.error(error)
pdfPrintAll(){
this.$refs.pdf.print()
pdfPrint(){
this.$refs.pdf.print(100,[1,2])

展示全部pdf
上面的示例只能显示单页的pdf,并且pdf的总页数也只能在pdf加载完成后才能获取。下面介绍createLoadingTask的用法,来显示所有pdf。
<template>
<div class="pdf">
<div class="pdf-tab">
:class="['btn-def',{'btn-active':activeIndex==index}]"
v-for="(item,index) in pdfList"
@click.stop="pdfClick(item.pdfUrl,index)">{{item.title}}</div>
v-for="i in numPages"
:key="i"
:src="pdfUrl"
:page="i">
</template>
<script>
import pdf from 'vue-pdf'
export default {
name: 'Pdf',
components:{
data(){
return {
pdfList:[
pdfUrl:"https://dakaname.oss-cn-hangzhou.aliyuncs.com/file/2018-12-29/1546049718768.pdf",

pdfUrl: '',
numPages:1,
activeIndex:0,
mounted: function() {
this.pdfTask(this.pdfList[0].pdfUrl)
methods: {
pdfTask(pdfUrl){
var self = this
var loadingTask = pdf.createLoadingTask(pdfUrl)
loadingTask.then(pdf => {
self.pdfUrl = loadingTask
self.numPages = pdf.numPages
}).catch((err) => {
console.error('pdf加载失败')
pdfClick(pdfUrl,index){
if(index == this.activeIndex)return
this.activeIndex = index
this.pdfUrl = null
this.pdfTask(pdfUrl)
