利用前端实现打印功能

先引入两个CSS,文件下载地址：https://github.com/xiaorenwu-dashijie/print.git

<link rel="stylesheet" type="text/css" href="css/print.css" media="print"/>

<link rel="stylesheet" type="text/css" href="css/screen.css" media="screen"/>

选中id为myDivId的div进行打印即可，前提是电脑能连上打印机

function printReport(){

var newstr = document.getElementById("myDivId").innerHTML;

var oldstr = document.body.innerHTML;

document.body.innerHTML = newstr;

window.print();

document.body.innerHTML = oldstr;

return false;

}

打印效果如下
