在vue中使用vue-layer+vue-pdf弹出框查看PDF,支持滚轮滚动 ctrl按住可缩放查看,输入页码跳转

先看效果图:
默认打开的弹出框 可自定义大小

可缩放弹框 全屏

缩放到左下角

下面教你使用
首先需要导入对应的插件
vue-layer 点击进入作者去查看相关属性及方法 本文只做弹出框+PDF展示 可以自定义

Attribut 官网可设置的属性
{
  type: 0, //0（信息框，默认）1（页面层）2（iframe层）3（加载层）4（tips层）
  title: '信息',
  content: '',
  area: 'auto',
  offset: 'auto',
  icon: -1,
  btn: '确定',
  time: 0,
  shade: true,//是否显示遮罩
  yes: '',
  cancel: '',
  tips: [0,{}],//支持上右下左四个方向，通过1-4进行方向设定,可以设定tips: [1, '#c00']
  tipsMore: false,//是否允许多个tips
  shadeClose: true,//点击遮罩是否关闭
  maxmin: true,//开启最大化最小化
  scrollbar: true, //是否允许浏览器出现滚动条:默认是允许
  resize: false //是否允许拉伸，默认是不允许
}

vue-layer  //npm install vue-layer
vue-pdf  //npm install vue-pdf

导入后需要在项目的main.js中引入插件

import layer from 'vue-layer'
import 'vue-layer/lib/vue-layer.css';
Vue.prototype.$layer = layer(Vue);

查看PDF的页面

 import pdfView from './pdfView'
 this.$layer.iframe({
            content: {
              content: pdfView, //传递的组件对象
              parent: this,//当前的vue对象
              data:{
                pdfUrl:this.src
              }//props
            },
            shade: 0,//不显示遮罩层
            maxmin: true,//显示最大化最小化按钮
            area:[width,height],
            title: '查看PDF',
             })

复制进入你的项目可以直接使用的
