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 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; } } //==加载引用CLodop的主JS,用双端口8000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")[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='#FF00FF'>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>"; var strHtmUpdate = "<br><font color='#FF00FF'>打印控件需要升级!点击这里<a href='install_lodop32.zip' target='_self'>执行升级</a>,升级后请重新进入。</font>"; var strHtm64_Install = "<br><font color='#FF00FF'>打印控件未安装!点击这里<a href='install_lodop64.zip' target='_self'>执行安装</a>,安装后请刷新页面或重新进入。</font>"; var strHtm64_Update = "<br><font color='#FF00FF'>打印控件需要升级!点击这里<a href='install_lodop64.zip' target='_self'>执行升级</a>,升级后请重新进入。</font>"; var strHtmFireFox = "<br><br><font color='#FF00FF'>(注意:如曾安装过Lodop旧版附件npActiveXPLugin,请在【工具】->【附加组件】->【扩展】中先卸它)</font>"; var strHtmChrome = "<br><br><font color='#FF00FF'>(如果此前正常,仅因浏览器升级或重安装而出问题,需重新执行以上安装)</font>"; var strCLodopInstall_1 = "<br><font color='#FF00FF'>Web打印服务CLodop未安装启动,点击这里<a href='CLodop_Setup_for_Win32NT.zip' target='_self'>下载执行安装</a>"; var strCLodopInstall_2 = "<br>(若此前已安装过,可<a href='CLodop.protocol:setup' target='_self'>点这里直接再次启动</a>)"; var strCLodopInstall_3 = ",成功后请刷新本页面。</font>"; var strCLodopUpdate = "<br><font color='#FF00FF'>Web打印服务CLodop需升级!点击这里<a href='CLodop_Setup_for_Win32NT.zip' target='_self'>执行升级</a>,升级后请刷新页面。</font>"; var LODOP; try { var ua = navigator.userAgent; var isIE = !!(ua.match(/MSIE/i)) || !!(ua.match(/Trident/i)); if (needCLodop()) { try { LODOP = getCLodop(); } catch (err) {} if (!LODOP && CLodopJsState !== "complete") { if (CLodopJsState == "loading") alert("网页还没下载完毕,请稍等一下再操作."); else alert("没有加载CLodop的主js,请先调用loadCLodop过程."); return; } if (!LODOP) { document.body.innerHTML = strCLodopInstall_1 + (CLodopIsLocal ? strCLodopInstall_2 : "") + strCLodopInstall_3 + document.body.innerHTML; return; } else { if (CLODOP.CVERSION < "4.0.9.9") { document.body.innerHTML = strCLodopUpdate + document.body.innerHTML; } if (oEMBED && oEMBED.parentNode) oEMBED.parentNode.removeChild(oEMBED); if (oOBJECT && oOBJECT.parentNode) oOBJECT.parentNode.removeChild(oOBJECT); } } else { var is64IE = isIE && !!(ua.match(/x64/i)); //==如果页面有Lodop就直接使用,否则新建:== if (oOBJECT || oEMBED) { if (isIE) LODOP = oOBJECT; else LODOP = oEMBED; } else if (!CreatedOKLodopObject) { LODOP = document.createElement("object"); LODOP.setAttribute("width", 0); LODOP.setAttribute("height", 0); LODOP.setAttribute("style", "position:absolute;left:0px;top:-100px;width:0px;height:0px;"); if (isIE) LODOP.setAttribute("classid", "clsid:2105C259-1E0C-4534-8141-A753534CB4CA"); else LODOP.setAttribute("type", "application/x-print-lodop"); document.documentElement.appendChild(LODOP); CreatedOKLodopObject = LODOP; } else LODOP = CreatedOKLodopObject; //==Lodop插件未安装时提示下载地址:== if ((!LODOP) || (!LODOP.VERSION)) { if (ua.indexOf('Chrome') >= 0) document.body.innerHTML = strHtmChrome + document.body.innerHTML; if (ua.indexOf('Firefox') >= 0) document.body.innerHTML = strHtmFireFox + document.body.innerHTML; document.body.innerHTML = (is64IE ?

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 = '<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>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(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。
