vue使用lodop打印控件實現(xiàn)瀏覽器兼容打印的方法

更新時間：2021年02月07日 11:40:55 作者：Allen-沐風(fēng)

這篇文章主要介紹了vue使用lodop打印控件實現(xiàn)瀏覽器兼容打印的方法，本文給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值,需要的朋友可以參考下

前言

此控件直接進(jìn)行打印底部會有水印，通過官網(wǎng)購買可以解決；
如不想購買，可先執(zhí)行預(yù)覽，彈出預(yù)覽框進(jìn)行打??；
需要用到的js文件和api文檔附后，請注意查看。
首先需要在局部或全局引入LodopFuncs.js文件
import {getLodop} from '../../../components/js/LodopFuncs'

方法中調(diào)用

print(){
   let LODOP = getLodop();
   LODOP.PRINT_INITA(0,0,800,1600,"打印庫位名稱");
   LODOP.SET_PRINT_PAGESIZE(1,700,500,"") //設(shè)定紙張大小
    LODOP.NewPage();//初始化
    LODOP.SET_PRINT_MODE("RESELECT_PRINTER",true);
    LODOP.ADD_PRINT_TEXT('10mm','50mm','30mm','20mm','iphone20Plus');//打印文字
    LODOP.SET_PRINT_STYLEA(0,"FontSize",30);//字體樣式
    LODOP.ADD_PRINT_LINE('10mm','35mm','40mm','35mm',0,1);//打印直線
    LODOP.ADD_PRINT_BARCODE('10mm','2.5mm','35mm','35mm',"QRCode",'123456');//打印二維碼
    LODOP.SET_PRINT_STYLEA(0,"AlignJustify",2);//二維碼樣式和規(guī)則
    LODOP.SET_PRINTER_INDEXA("TSC TTP-244 Pro");//選擇打印機
   // LODOP.PRINT_DESIGN()//打開設(shè)置
   // LODOP.PREVIEW(); //預(yù)覽
    LODOP.PRINT() //直接打印
  },

LodopFuncs.js文件

//==本JS是加載Lodop插件及CLodop服務(wù)的綜合示例，可直接使用，建議看懂后融進(jìn)自己頁面程序==

var CreatedOKLodopObject, CLodopIsLocal, CLodopJsState;


//==判斷是否需要CLodop(那些不支持插件的瀏覽器):==
export function needCLodop() {
  try {
    var ua = navigator.userAgent;
    if (ua.match(/Windows\sPhone/i))
      return true;
    if (ua.match(/iPhone|iPod|iPad/i))
      return true;
    if (ua.match(/Android/i))
      return true;
    if (ua.match(/Edge\D?\d+/i))
      return true;

    var verTrident = ua.match(/Trident\D?\d+/i);
    var verIE = ua.match(/MSIE\D?\d+/i);
    var verOPR = ua.match(/OPR\D?\d+/i);
    var verFF = ua.match(/Firefox\D?\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(/Chrome\D?\d+/i);
      if (verChrome) {
        verChrome = verChrome[0].match(/\d+/);
        if (verChrome[0] >= 41)
          return true;
      }
    }
    return false;
  } catch (err) {
    return true;
  }
}

//==引用CLodop的主JS,用雙端口8000和18000(以防其中一個被占):==
if (needCLodop()) {
  var head = document.head || document.getElementsByTagName("head")[0] || document.documentElement;
  
  var JS1 = document.createElement("script");
  JS1.src = "http://localhost:8000/CLodopfuncs.js?priority=1";
  head.insertBefore(JS1, head.firstChild);

  var JS2 = document.createElement("script");
  JS2.src = "http://localhost:18000/CLodopfuncs.js?priority=0";
  head.insertBefore(JS2, head.firstChild);

  CLodopIsLocal = !!((JS1.src + JS2.src).match(/\/\/localho|\/\/127.0.0./i));

  if (JS1.attachEvent) {
  	CLodopJsState = "loading";
    var onChange = function(){ 
	   if (window.event.srcElement.readyState == 'loaded')        
	   CLodopJsState = "complete";
	};
	JS1.attachEvent('onreadystatechange',onChange);
	JS2.attachEvent('onreadystatechange',onChange);
  }
}

//==獲取LODOP對象主過程,判斷是否安裝、需否升級:==
export function getLodop(oOBJECT, oEMBED) {
  var strHtmInstall = "<br><font color='#FF00FF'>打印控件未安裝!點擊這里<a  target='_self'>執(zhí)行安裝</a>,安裝后請刷新頁面或重新進(jìn)入。</font>";
