JS實現快遞單列印功能

最近做專案需要列印快遞單,在網上搜索了一下發現直接給出程式碼的比較少。
首先說一下js網頁列印的幾種方法:
1.window.print()
會彈出列印對話方塊
2.使用html 標籤引入Webbrowser控制元件
這種方式是其只相容IE10以下的瀏覽器,其他瀏覽器不可使用
3.document.execCommand(”print”)
類似window.print()
4.採用JQuery外掛
5.用瀏覽器列印第三方外掛如lodpod等

由於我這邊不需要相容ie10以下,而且個人不喜歡在react專案中引入jquery,同時嫌第三方外掛太麻煩,最終選擇window.print(),具體這幾種方法區別大家可以去網上查一下,這類部落格很多。
廢話不多說,直接貼程式碼

通過css3 print控制列印樣式,不需要列印的可以通過新增 class為noPrint來隱藏

一開始在ff和chrome打印出來的會有細微差別,這是由於瀏覽器自帶樣式的影響,清除瀏覽器樣式後基本沒區別了
還有就是chrome需要將瀏覽器設定裡自定義字型中最小字型調到最低,不然會影響列印效果
ff這需要在列印裡設定頁頭頁尾為空白,不然列印的帶頁頭頁尾。
此外chrome打印出來的比ff清楚,這點原因我還沒搞清楚。
貼兩張列印預覽,上面是chrome,下面是ff
