h5预览pdf

背景

在h5中预览pdf，原做法是直接location.href，但是内嵌网页在ios和android上的表现出入太大，因此选择使用组件实现，经过多次试错，最终选择了pdfh5官方文档。

直接上代码

页面调用就很简单了

<template lang="pug">
div
    PdfViewer(:pdfurl="pdfurl")
</template>

结果

完美实现兼容，目前还未发现问题。

注意事项

详细文档和需要下载的文件请点击最上方的官方文档，这里仅做接入示例参考。
在index.html里引入，主要是因为文件过大，打包的时候会报警。
我的项目使用的是vite+vue3，如果用vue2的话记得注意区分。
