更新時間：2023年01月30日 11:32:47 作者：廷賀

lodop 取意自“l(fā)oad or print”，是一款優(yōu)秀的 Web 打印控件。本文將在Vue中集成lodop插件實(shí)現(xiàn)打印功能，感興趣的小伙伴可以了解一下

VUE簡單使用lodop

1.創(chuàng)建LodopFuncs.js文件

js 內(nèi)容如下

//==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;
    }
}

//==加載引用CLodop的主JS,用雙端口8000和18000(以防其中一個被占):==
export function loadCLodop() {
    if (CLodopJsState == "loading" || CLodopJsState == "complete") return;
    CLodopJsState = "loading";
    var head = document.head || document.getElementsByTagName("head")[0] || document.documentElement;
    var JS1 = document.createElement("script");
    var JS2 = document.createElement("script");
    JS1.src = "http://localhost:8000/CLodopfuncs.js?priority=1";
    JS2.src = "http://localhost:18000/CLodopfuncs.js";
    JS1.onload  = JS2.onload  = function()    {CLodopJsState = "complete";}
    JS1.onerror = JS2.onerror = function(evt) {CLodopJsState = "complete";}
    head.insertBefore(JS1, head.firstChild);
    head.insertBefore(JS2, head.firstChild);
    CLodopIsLocal = !!((JS1.src + JS2.src).match(/\/\/localho|\/\/127.0.0./i));
}

if (needCLodop()){loadCLodop();}//加載

}

2.在打印功能vue頁面引入LodopFuncs

import { getLodop } from '../../tools/LodopFuncs'
let LODOP;

3.執(zhí)行打印方法

methods: {
	//提交打印
	submitForm(formName) {
		LODOP = getLodop()// 獲取LODOP對象的主過程
          if (LODOP != false) {
	          const data = [{}]
	          this.dayin(data)
          }
	},
	setDayinData(temp) {
      // 整理打印數(shù)據(jù)
      console.log('整理打印數(shù)據(jù)————>>>s')
      this.dayinData.enterAmount = temp.enterAmount
      this.dayinData.versionNo = temp.versionNo
      this.dayinData.productBatchNo = temp.productBatchNo
      this.dayinData.remarks = temp.remarks
      this.dayinData.productId = temp.productId
      this.dayinData.productLineId = temp.productLineId
      this.dayinData.shiftsType = temp.shiftsType
      this.dayinData.productSpecId = temp.productSpecId
      this.dayinData.sheetId = temp.sheetId

      const strTaskName = 'XX單' + temp.productBatchNo
      console.log('整理打印數(shù)據(jù)————>>>e')
      return strTaskName
    },
	dayin(data) {
	      LODOP = getLodop()// 獲取LODOP對象的主過程
        const strTaskName = this.setDayinData(data)

        const P_ID = ''
        // const Heg = document.getElementById('toPrint').clientHeight + 50
        // 打印初始化 設(shè)定打印任務(wù)名
        console.log(strTaskName, '打印任務(wù)名', LODOP.VERSION)
        LODOP.PRINT_INIT(strTaskName)
        LODOP.SET_PRINTER_INDEX(-1)// -1特指操作系統(tǒng)內(nèi)設(shè)定的默認(rèn)打印機(jī)

        // LODOP.SET_PRINT_PAGESIZE(3, '', '', '')// 設(shè)置紙張
        // LODOP.SET_PRINT_MODE('PRINT_PAGE_PERCENT', 'Auto-Width')// 設(shè)置以紙張邊緣為基點(diǎn)
        // LODOP.SET_PRINT_STYLE('FontSize', 11)// 設(shè)置字體
        // LODOP.ADD_PRINT_HTM(1, 0, 350, Heg, document.getElementById('toPrint').innerHTML)
        var strStyle = '<style>' +
          '.my-table{border-top:none;border-collapse:collapse;width:auto}' +
          '.my-table tr{width:100%;text-align:center}' +
          '.my-table td{padding:5px;font-size:13px}' +
          '.my-td{border-bottom:#f2f2f2 solid 1px}' +
          '</style>'
        var html = '<table class="my-table":v-model="dayinData"><tr><td>產(chǎn)品名稱</td><td class="my-td"></td><td/></tr><tr><td>發(fā)貨區(qū)域</td><td/><td/></tr></table>'
        LODOP.ADD_PRINT_TABLE(1, 0, '100mm', '150mm', strStyle + html)
        // LODOP.ADD_PRINT_TABLE(1, 0, '100mm', '150mm', strStyle + document.getElementById('toPrint').innerHTML)
        // LODOP.ADD_PRINT_HTM(3, '100%', 300, 100, '')// 右上角的頁碼
        // LODOP.ADD_PRINT_TEXT(3, 34, 196, 20, '')// 左上角的文字
        // LODOP.PRINT()// 直接打印
        LODOP.PREVIEW()// 打印預(yù)覽
	    },
	
	}

4.打印接口函數(shù)官網(wǎng)樣例說明

● PRINT_INIT(strPrintTaskName)打印初始化

● SET_PRINT_PAGESIZE(intOrient,intPageWidth,intPageHeight,strPageName)設(shè)定紙張大小

● ADD_PRINT_HTM(intTop,intLeft,intWidth,intHeight,strHtml)增加超文本項(xiàng)

● ADD_PRINT_TEXT(intTop,intLeft,intWidth,intHeight,strContent)增加純文本項(xiàng)

● ADD_PRINT_TABLE(intTop,intLeft,intWidth,intHeight,strHtml)增加表格項(xiàng)

● ADD_PRINT_SHAPE(intShapeType,intTop,intLeft,intWidth,intHeight,intLineStyle,intLineWidth,intColor)畫圖形

● SET_PRINT_STYLE(strStyleName, varStyleValue)設(shè)置對象風(fēng)格

● PREVIEW打印預(yù)覽

● PRINT直接打印

● PRINT_SETUP打印維護(hù)

● PRINT_DESIGN打印設(shè)計(jì)

從這里去Lodop官博，更多留言和討論請加入QQ群。

最基本的打印過程至少有初始化語句、添內(nèi)容語句和打印語句三部分組成，例如：

LODOP.PRINT_INIT("打印任務(wù)名");               //首先一個初始化語句
LODOP.ADD_PRINT_TEXT(0,0,100,20,"文本內(nèi)容一");//然后多個ADD語句及SET語句
LODOP.PRINT();                               //最后一個打印(或預(yù)覽、維護(hù)、設(shè)計(jì))語句

下面通過演示樣例來理解，為容易看懂源代碼，每個樣例盡量簡單，一個樣例代

表一類或多類功能,在實(shí)際應(yīng)用中它們都可以混合并存或交叉使用。
