JS调用浏览器的打印功能
Posted

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了JS调用浏览器的打印功能相关的知识，希望对你有一定的参考价值。
参考技术A 最近做一个后台管理系统，其中有个用户需求要求调用 浏览器打印 的功能去打印订单，本来以为需要用户手动（ Ctrl+P ）、或者打开 右键菜单 ，再选择打印功能。后来经过查询文档，JS提供了调用浏览器打印功能的API。页面（全屏弹窗）内容设计如上图所示：
其中页面右下方有两个按钮：
这样可以调用浏览器打印功能，但是打印预览页面上会出现右下方的两个按钮，这肯定是用户不想看到的。
因此还需要根据 CSS媒体查询 来区分：

打印功能的实现往往是新建一个页面，然后在新建页面中画出你想要的效果，然后调用浏览器的打印功能进行打印
项目依赖：
layui
jquery
记得换layui和jquery引入路径完整项目代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>layui打印</title>
<link rel="stylesheet" href="layui/css/layui.css" media="all" />
</head>
<body class="layui-bg-gray">
<div style="margin: 20px;">
<div class="layui-card">
<div class="layui-card-body">
<button type="button" class="layui-btn layui-btn-normal"
onclick="print('test')">layui自定义打印表格</button>
<button id="printSelect" type="button" class="layui-btn layui-btn-normal">自定义打印</button>
</div>

<div class="layui-card">
<div class="layui-card-body">
