JS实现快递单打印功能【推荐】

时间：2021-05-26

最近做项目需要打印快递单，在网上搜索了一下发现直接给出代码的比较少。

首先说一下js网页打印的几种方法：

1.window.print()

会弹出打印对话框

2.使用html 标签引入Webbrowser控件

这种方式是其只兼容IE10以下的浏览器，其他浏览器不可使用

3.document.execCommand(”print”)

类似window.print()

**4.采用JQuery插件

5.用浏览器打印第三方插件如lodpod等**

由于我这边不需要兼容ie10以下，而且个人不喜欢在react项目中引入jquery，同时嫌第三方插件太麻烦，最终选择window.print()，具体这几种方法区别大家可以去网上查一下，这类博客很多。

废话不多说，直接贴代码

<!DOCTYPE html><html><head> <meta charset=" utf-8"> <title>打印</title> <link rel="stylesheet" href="./print.css" rel="external nofollow" type="text/css"> <style type="text/css"> @import url("print.css") print; </style> <script language="javascript"> function remove_ie_header_and_footer() { let HKEY_Root, HKEY_Path, HKEY_Key; HKEY_Root = "HKEY_CURRENT_USER"; HKEY_Path = "\\Software\\Microsoft\\Internet Explorer\\PageSetup\\"; try { let RegWsh = new ActiveXObject("WScript.Shell"); HKEY_Key = "header"; RegWsh.RegWrite(HKEY_Root + HKEY_Path + HKEY_Key, ""); HKEY_Key = "footer"; RegWsh.RegWrite(HKEY_Root + HKEY_Path + HKEY_Key, ""); } catch (e) {} } function printPage(printpage) { if (!!window.ActiveXObject || "ActiveXObject" in window) { //是否ie remove_ie_header_and_footer(); } let newstr = printpage.innerHTML; let oldstr = document.body.innerHTML; document.body.innerHTML =newstr; window.print(); document.body.innerHTML=oldstr; return false; } window.onload = function() { let bt=document.getElementById("bt"); let page=document.getElementById("printPage"); bt.onclick=function() { printPage(page); } } </script></head><body><!--startPrint--><div id="printPage" > <div id="emsType" class="left"> <span class="deviation">标准快递</span> </div> <div id="barcode" class="right"> <span class="deviation">二维码</span> </div> <div id="sender" class="left"> <span class="deviation">寄件：</span> <span>xxxx</span> </div> <div id="area" class="right"> <span class="deviation">xxx区</span> </div> <div id="recipient" class="left"> <span class="deviation">收件：</span> <span class="deviation">xxxx人xxxx手机xxxxxxx</span> <span class="deviation">xxxxxxxx小区</span> </div> <div id="pay" class="left"> <span class="deviation">付款方式：</span> <span></span> <br/> <span class="deviation">计费重量（KG）：</span> <span></span> <br/> <span class="deviation">保价金额（元）：</span> <span></span> <br/> </div> <div id="delivers" class="right"> <span class="deviation">收件人\代收人：</span> <span></span> <br/> <span class="deviation">签收时间：</span> <span></span> <span>年</span> <span></span> <span>月</span> <span></span> <span>日</span> <span></span> <span>时</span> <br/> <span id="note">快件送达收货人地址，经收件人或收件人允许的代收人签字，视为送达</span> </div> <div id="order" class="left"> <span class="deviation">订单号：</span> <span></span> <span class="deviation">件数：</span> <span></span> <span class="deviation">重量（KG）：</span> <span></span> <span></span> </div> <div id="divide" class="left"> </div> <div id="number" class="left right"> <span class="deviation">条码</span> </div> <div id="send" class="left right"> <span class="deviation">寄件：</span> <span></span> </div> <div id="pickup" class="right"> <span class="deviation">收件：</span> <span></span> </div> <div id="remark" class="left"> <span class="deviation">备注：</span> <span></span> </div> <div id="net" class="left"> <span class="deviation">www.ems.cn &nbsp;&nbsp;&nbsp;&nbsp; 客服电话：11183</span> </div> <div id="QRCode" class="right"> <span class="deviation">二维码</span> </div></div><!--endPrint--><input name="print" class=" no-print" type="button" id="bt" value="点击打印" /></body></html>

通过css3 print控制打印样式，不需要打印的可以通过添加 class为noPrint来隐藏

@media print{ body, h1, h2, h3, h4, h5, h6, hr, p, blockquote, dl, dt, dd, ul, ol, li, pre, form, fieldset, legend, button, input, textarea, th, td { margin:0; padding:0; } body, button, input, select, textarea { font:12px/1.5 arial,"黑体", \5b8b\4f53; } h1, h2, h3, h4, h5, h6{ font-size:100%; } address, cite, dfn, em, var { font-style:normal; } code, kbd, pre, samp { font-family:couriernew, courier, monospace; } small{ font-size:12px; } ul, ol { list-style:none; } a { text-decoration:none; } a:hover { text-decoration:underline; } sup { vertical-align:text-top; } sub{ vertical-align:text-bottom; } legend { color:#000; } fieldset, img { border:0; } button, input, select, textarea { font-size:100%; } table { border-collapse:collapse; border-spacing:0; } .no-print{ display:none; } @page{ size: 100mm 150mm; margin: 1.75mm; } #printPage { width: 96mm; height: 146mm; position: relative; border: 1px dotted #000000; box-sizing: border-box; } #printPage span{ margin-left: 2mm; } .left { border-left: 1px dotted #000000; border-right: 1px dotted #000000; border-bottom: 1px dotted #000000; left: 0; } .right { border-right: 1px dotted #000000; border-bottom: 1px dotted #000000; } .deviation{ margin-left: 2mm; } #emsType{ width: 40mm; height: 14mm; position: absolute; top: 0; padding-top: 6mm; font-size: 20px; border-top: 1px dotted #000000; } #barcode{ width: 56mm; height: 20mm; position: absolute; top: 0; left: 40mm; border-top: 1px dotted #000000; } #sender{ width: 46mm; height: 15mm; font-size: 12px; position: absolute; top: 20mm; } #area{ width: 50mm; height: 15mm; position: absolute; top: 20mm; left: 46mm; } #recipient{ width: 96mm; height: 17mm; position: absolute; left: 0; top: 35mm; font-size: 12px; } #pay{ width: 40mm; height: 14mm; position: absolute; top: 52mm; font-size: 12px; } #delivers{ width: 56mm; height: 14mm; position: absolute; top: 52mm; left: 40mm; font-size: 12px; } #order{ width: 96mm; height: 20mm; position: absolute; left: 0; top: 66mm; font-size: 12px; } #divide{ width: 96mm; height: 4mm; position: absolute; left: 0; top: 86mm; } #number{ width: 96mm; height: 15mm; position: absolute; left: 0; top: 90mm; font-size: 12px; } #send{ width: 40mm; height: 17mm; position: absolute; top: 105mm; font-size: 12px; } #pickup{ width: 56mm; height: 17mm; position: absolute; top: 105mm; left: 40mm; font-size: 12px; } #remark{ width: 68mm; height: 17mm; position: absolute; top: 122mm; font-size: 12px; } #net{ width: 68mm; height: 7mm; position: absolute; top: 139mm; font-size: 12px; } #QRCode{ width: 28mm; height: 24mm; position: absolute; top: 122mm; left: 68mm; } #note{ font-size: 6px; }}

一开始在ff和chrome打印出来的会有细微差别，这是由于浏览器自带样式的影响，清除浏览器样式后基本没区别了还有就是chrome需要将浏览器设置里自定义字体中最小字体调到最低，不然会影响打印效果 ff这需要在打印里设置页头页脚为空白，不然打印的带页头页脚。

此外chrome打印出来的比ff清楚，这点原因我还没搞清楚。

贴两张打印预览，上面是chrome，下面是ff
