关于vue.js:vue项目添加CLodop批量打印和单个打印

jiezi

请在 C -Lodop 官网中下载插件
1、在 src/utils 中增加 LodopFuncs.js 文件 

var CreatedOKLodop7766 = null, CLodopIsLocal;

//==== 判断是否须要 Web 打印服务 CLodop:===

//===(不反对插件的浏览器版本须要用它)===

export function needCLodop() {

 try {

 var ua = navigator.userAgent;

 if (ua.match(/WindowssPhone/i))

 return true;

 if (ua.match(/iPhone|iPod|iPad/i))

 return true;

 if (ua.match(/Android/i))

 return true;

 if (ua.match(/EdgeD?d+/i))

 return true;

 var verTrident = ua.match(/TridentD?d+/i);

 var verIE = ua.match(/MSIED?d+/i);

 var verOPR = ua.match(/OPRD?d+/i);

 var verFF = ua.match(/FirefoxD?d+/i);

 var x64 = ua.match(/x64/i);

 if ((!verTrident) && (!verIE) && (x64))

 return true;

 else if (verFF) {verFF = verFF[0].match(/d+/);

 if ((verFF[0] >= 41) || (x64))

 return true;

 } else if (verOPR) {verOPR = verOPR[0].match(/d+/);

 if (verOPR[0] >= 32)

 return true;

 } else if ((!verTrident) && (!verIE)) {var verChrome = ua.match(/ChromeD?d+/i);

 if (verChrome) {verChrome = verChrome[0].match(/d+/);

 if (verChrome[0] >= 41)

 return true;

 }

 }

 return false;

 } catch (err) {return true;}

}

//==== 页面援用 CLodop 云打印必须的 JS 文件, 用双端口 (8000 和 18000）防止其中某个被占用：====

2、页面援用 

import {getLodop} from '@/utils/LodopFuncs'

3、vue 中 html 代码 

<!-- 全副打印 -->
<a-dropdown>
 <a-button icon="printer" type="primary">
    打印全副
    <a-icon type="down" />
 </a-button>
 <a-menu slot="overlay">
    <a-menu-item type="primary" @click="printPreview(0,'all')"> 间接打印 </a-menu-item>
    <a-menu-item type="primary" @click="printPreview(1,'all')"> 打印预览 </a-menu-item>
     <a-menu-item type="primary" @click="printPreview(2,'all')"> 打印保护 </a-menu-item>
    <a-menu-item type="primary" @click="printPreview(3,'all')"> 打印设计 </a-menu-item>
  </a-menu>
</a-dropdown>
<!-- 单个打印，通过 index 下标 -->
<a-dropdown>
 <a-button icon="printer" type="primary">
    打印全副
    <a-icon type="down" />
 </a-button>
 <a-menu slot="overlay">
