使用element 在线预览pdf
- npm pdf
npm install --save vue-pdf
- 导入 pdf
import pdf from 'vue-pdf';
- components中添加 pdf
components: {
pdf
},
- 简单使用
<pdf
:src="url"
:page="pdfPage"
@num-pages="pageCount = $event"
@page-loaded="pdfPage = $event"
style="display: inline-block; width: 100%"
></pdf>
- 添加样式 viewVisible为true时显示
<el-dialog
:title="pdfTiTle"
:visible.sync="viewVisible" width="80%" center
:append-to-body="true"
@close='closeDialog'
>
<div style="margin-bottom: 15px; text-align: right">
<el-button type="primary" size="small" @click.stop="previousPage">
上一页
</el-button>
<el-button type="primary" size="small" @click.stop="nextPage">
下一页
</el-button>
<span>当前第{{pdfPage}}页 / 共{{pageCount}}页</span>
</div>
<div>
<pdf
:src="url"
:page="pdfPage"
@num-pages="pageCount = $event"
@page-loaded="pdfPage = $event"
style="display: inline-block; width: 100%"
></pdf>
</div>
</el-dialog>
//关闭窗口初始化PDF页码
closeDialog(){
this.pdfPage = 1;
this.viewVisible = false;
},
//PDF改变页数
previousPage(){
var p = this.pdfPage
p = p>1?p-1:this.pageCount
this.pdfPage = p
},
nextPage(){
var p = this.pdfPage
p = p<this.pageCount?p+1:1
this.pdfPage = p
}
传入文件名 获取后缀(return pdf),用来判断存在
//传入文件名 获取后缀
extname(filename){
if(!filename||typeof filename!='string'){
return false
};
let a = filename.split('').reverse().join('');
let b = a.substring(0,a.search(/\./)).split('').reverse().join('');
return b
},
