vue预览本地pdf文件方法之vue-pdf组件使用_Vue.js

1、npm安装

npm install --save vue-pdf

2、页面引入

3、具体实现

<div class="pdf" v-show="filetype === 'pdf'">
<p class="arrow">
    <span @click="changepdfpage(0)" class="turn" 
             :class="{grey: currentpage==1}">preview</span>
    {{currentpage}} / {{pagecount}}
    <span @click="changepdfpage(1)" class="turn" 
            :class="{grey: currentpage==pagecount}">next</span>
</p>                              
<pdf  :src="pdfsrc" :page="currentpage" @num-pages="pagecount=$event" 
        @page-loaded="currentpage=$event"   @loaded="loadpdfhandler">
</pdf>
</div>

4、method方法

// 改变pdf页码,val传过来区分上一页下一页的值,0上一页,1下一页
      changepdfpage (val) {
        // console.log(val)
        if (val === 0 && this.currentpage > 1) {
          this.currentpage--
          // console.log(this.currentpage)
        }
        if (val === 1 && this.currentpage < this.pagecount) {
          this.currentpage++
          // console.log(this.currentpage)
        }
      },
 
      // pdf加载时
      loadpdfhandler (e) {
        this.currentpage = 1 // 加载的时候先加载第一页
      },
