安装file-saver
npm install file-saver --save
// 页面完整代码
<template>
<div id="pcContract">
<div @click="download()">合同</div>
<img src="../../assets/logo.png" alt="" />
</div>
</template>
<script>
// eslint-disable-next-line no-unused-vars
import saveAs from 'file-saver'
import '../../utils/jquery.wordexport'
export default {
data() {
return {}
},
created: function() {},
methods: {
download() {
// eslint-disable-next-line no-undef
$('#pcContract').wordExport('文档')
},
},
}
</script>
<style lang="scss" scoped></style>
这样就能把vue页面下载成word文档啦
