Vue集成lodop插件实现打印功能

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;

//==加载引用CLodop的主JS,用双端口8000和18000(以防其中一个被占):==

    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";

}

if (needCLodop()){loadCLodop();}//加载

//==获取LODOP对象主过程,判断是否安装、需否升级:==

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 + 50
        // 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)// -1特指操作系统内设定的默认打印机

        // LODOP.SET_PRINT_PAGESIZE(3, '', '', '')// 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', 11)// 设置字体
        // LODOP.ADD_PRINT_HTM(1, 0, 350, Heg, document.getElementById('toPrint').innerHTML)
        var strStyle = ''
        var html = '
产品名称
发货区域
' 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, '')// 右上角的页码 // LODOP.ADD_PRINT_TEXT(3, 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(0,0,100,20,"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。
