Vue3实现打印功能
1、安装插件
npm i vue3-print-nb --save2、main.js全局配置
import print from 'vue3-print-nb'
app.use(print)3、设置打印区域
为打印区域设置 id 选择器
<div id="printData"><el-table border :data="tableData" style="width: 100%"><el-table-column prop="date" label="Date" width="180" /><el-table-column prop="name" label="Name" width="180" /><el-table-column prop="address" width="180" label="Address" /></el-table>
</div>4、绑定打印事件
为打印按钮绑定 v-print
<el-button v-print="print" type="success">点击打印</el-button>
// 打印
const print = {id: "printData",popTitle: "打印数据",
};5、完整代码
<template><div><el-card><template #header><el-button v-print="print" type="success">点击打印</el-button></template><div id="printData"><el-table border :data="tableData" style="width: 100%"><el-table-column prop="date" label="Date" width="180" /><el-table-column prop="name" label="Name" width="180" /><el-table-column prop="address" width="180" label="Address" /></el-table></div></el-card></div>
</template>
<script setup>
const tableData = [{date: "2024-05-03",name: "知否君",address: "中国北京",},{date: "2024-05-02",name: "工藤新一",address: "中国上海",},
];
// 打印
const print = {id: "printData",popTitle: "打印数据",
};
</script>
<style lang="scss" scoped>
@page {size: auto;margin-bottom: 5mm;
}
</style>
6、解决打印表格无边框
使用原生table
<div id="printData"><table class="printTable" border="1"><thead><tr><th>姓名</th><th>生日</th><th>地址</th></tr></thead><tbody><tr><td>张三</td><td>1998-02-25</td><td>河北避暑山庄</td></tr><tr><td>李四</td><td>1996-02-24</td><td>北京大兴</td></tr><tr><td>王五</td><td>1997-02-26</td><td>浙江杭州</td></tr></tbody></table>
</div>
.printTable {color: #616161;width: 100%;border-collapse: collapse;border: 0.25px solid #ededed;text-align: left;font-size: 15px;th,td {padding: 6px;}
}
7、解决单选框复选框打印不选中
@media print {::v-deep .el-radio__input,::v-deep .el-checkbox__input {-webkit-print-color-adjust: exact;-moz-print-color-adjust: exact;color-adjust: exact;}
}8、去除页脚页眉
@page {size: auto;margin: 0mm;}9、解决打印內容不自动换行
word-wrap:break-word;
