1.window.print()

<template>

<div id="contenteBox">内容</div>

<button @click="printContent">打印</button>

</template>

<script>

export default{

data(){

return{}

},

methods:{

printContent(){

let contentDom=document.getElementById('contenteBox')

let html=`

<head>

<style lang='scss'>

#contenteBox{font-size:18px;background-color:#333}

<style>

</head>

<body>${contentDom.innerHTML}</body>

`

window.print()

}

}

}

</script>

let contentDom=document.getElementById('contenteBox') //获取id为contenteBox的dom元素

html //设置打印主体以及css样式

window.print() //打印

也可以let bodyContent = document.getElementById('contenteBox').innerHTML 通过获取需要打印的元素

通过 document.body.innerHTML=bodyContent 把当前页面替换为打印内容HTML

window.print()打印 //记得最后还原页面
