VUE 集成LODOP插件打印

Lodop、C-Lodop使用说明及样例

http://www.lodop.net/LodopDemo.html

VUE简单使用lodop

1.创建LodopFuncs.js文件

js 内容如下

//==本JS是加载Lodop插件及CLodop服务的综合示例，可直接使用，建议看懂后融进自己页面程序==

var CreatedOKLodopObject, CLodopIsLocal, CLodopJsState;

//==判断是否需要CLodop(那些不支持插件的浏览器):==
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 x = ua.match(/x64/i);
        if ((!verTrident) && (!verIE) && (x))
            return true;
        else if (verFF) {
            verFF = verFF[].match(/\d+/);
            if ((verFF[] >= 41) || (x64))
                return true;
        } else if (verOPR) {
            verOPR = verOPR[].match(/\d+/);
            if (verOPR[] >= 32)
                return true;
        } else if ((!verTrident) && (!verIE)) {
            var verChrome = ua.match(/Chrome\D?\d+/i);
            if (verChrome) {
                verChrome = verChrome[].match(/\d+/);
                if (verChrome[] >= 41)
                    return true;
            }
        }
        return false;
    } catch (err) {
        return true;
    }
}

//==加载引用CLodop的主JS,用双端口和18000(以防其中一个被占):==
export function loadCLodop() {
    if (CLodopJsState == "loading" || CLodopJsState == "complete") return;
    CLodopJsState = "loading";
    var head = document.head || document.getElementsByTagName("head")[] || document.documentElement;
    var JS = document.createElement("script");
    var JS = document.createElement("script");
    JS.src = "http://localhost:8000/CLodopfuncs.js?priority=1";
    JS.src = "http://localhost:18000/CLodopfuncs.js";
    JS.onload  = JS2.onload  = function()    {CLodopJsState = "complete";}
    JS.onerror = JS2.onerror = function(evt) {CLodopJsState = "complete";}
    head.insertBefore(JS, head.firstChild);
    head.insertBefore(JS, head.firstChild);
    CLodopIsLocal = !!((JS.src + JS2.src).match(/\/\/localho|\/\/127.0.0./i));
}

if (needCLodop()){loadCLodop();}//加载

//==获取LODOP对象主过程,判断是否安装、需否升级:==
export function getLodop(oOBJECT, oEMBED) {
    var strHtmInstall = "<br><font color='#FFFF'>打印控件未安装!点击这里<a href='install_lodop32.zip' target='_self'>执行安装</a>,安装后请刷新页面或重新进入。</font>";

                LODOP = document.createElement("object");
                LODOP.setAttribute("width",);
                LODOP.setAttribute("height",);
                LODOP.setAttribute("style", "position:absolute;left:px;top:-100px;width:0px;height:0px;");

        return LODOP;
    } catch (err) {
        alert("getLodop出错:" + err);
    }
}

2.在打印功能vue页面引入LodopFuncs

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

3.执行打印方法

methods: {
	//提交打印
	submitForm(formName) {
		LODOP = getLodop()// 获取LODOP对象的主过程
          if (LODOP != false) {
	          const data = [{}]
	          this.dayin(data)
          }
	},
	setDayinData(temp) {
      // 整理打印数据
      console.log('整理打印数据————>>>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单' + temp.productBatchNo
      console.log('整理打印数据————>>>e')
      return strTaskName
    },
	dayin(data) {
	      LODOP = getLodop()// 获取LODOP对象的主过程
        const strTaskName = this.setDayinData(data)

        const P_ID = ''
        // const Heg = document.getElementById('toPrint').clientHeight +
        // 打印初始化 设定打印任务名
        console.log(strTaskName, '打印任务名', LODOP.VERSION)
        LODOP.PRINT_INIT(strTaskName)
        LODOP.SET_PRINTER_INDEX(-)// -1特指操作系统内设定的默认打印机

        // LODOP.SET_PRINT_PAGESIZE(, '', '', '')// 设置纸张
        // LODOP.SET_PRINT_MODE('PRINT_PAGE_PERCENT', 'Auto-Width')// 设置以纸张边缘为基点
        // LODOP.SET_PRINT_STYLE('FontSize',)// 设置字体
        // LODOP.ADD_PRINT_HTM(, 0, 350, Heg, document.getElementById('toPrint').innerHTML)
        var strStyle = '<style>' +
          '.my-table{border-top:none;border-collapse:collapse;width:auto}' +
          '.my-table tr{width:%;text-align:center}' +
          '.my-table td{padding:px;font-size:13px}' +
          '.my-td{border-bottom:#ff2f2 solid 1px}' +
          '</style>'
        var html = '<table class="my-table":v-model="dayinData"><tr><td>产品名称</td><td class="my-td"></td><td/></tr><tr><td>发货区域</td><td/><td/></tr></table>'
        LODOP.ADD_PRINT_TABLE(, 0, '100mm', '150mm', strStyle + html)
        // LODOP.ADD_PRINT_TABLE(, 0, '100mm', '150mm', strStyle + document.getElementById('toPrint').innerHTML)
        // LODOP.ADD_PRINT_HTM(, '100%', 300, 100, '')// 右上角的页码
        // LODOP.ADD_PRINT_TEXT(, 34, 196, 20, '')// 左上角的文字
        // LODOP.PRINT()// 直接打印
        LODOP.PREVIEW()// 打印预览
	    },
	
	}

4.打印接口函数官网样例说明

●   PRINT_INIT(strPrintTaskName)打印初始化

●   SET_PRINT_PAGESIZE(intOrient,intPageWidth,intPageHeight,strPageName)设定纸张大小

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

●   ADD_PRINT_TEXT(intTop,intLeft,intWidth,intHeight,strContent)增加纯文本项

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

●   ADD_PRINT_SHAPE(intShapeType,intTop,intLeft,intWidth,intHeight,intLineStyle,intLineWidth,intColor)画图形

●   SET_PRINT_STYLE(strStyleName, varStyleValue)设置对象风格

●   PREVIEW打印预览

●   PRINT直接打印

●   PRINT_SETUP打印维护

●   PRINT_DESIGN打印设计

 从这里去Lodop官博，更多留言和讨论请加入QQ群。

最基本的打印过程至少有初始化语句、添内容语句和打印语句三部分组成，例如：

LODOP.PRINT_INIT("打印任务名");               //首先一个初始化语句
LODOP.ADD_PRINT_TEXT(,0,100,20,"文本内容一");//然后多个ADD语句及SET语句
LODOP.PRINT();                               //最后一个打印(或预览、维护、设计)语句

下面通过演示样例来理解，为容易看懂源代码，每个样例尽量简单，一个样例代

表一类或多类功能,在实际应用中它们都可以混合并存或交叉使用。
