VUE中使用CLodop获取打印机列表并打印表格、图片等

打印如下表格（含图片）

1.在vue项目中，创建一个js文件，引入以下代码

var CreatedOKLodop7766=null //====判断是否需要安装CLodop云打印服务器:==== export function needCLodop(){ try{ var ua=navigator.userAgent if (ua.match(/Windows\sPhone/i) !=null) return true if (ua.match(/iPhone|iPod/i) != null) return true if (ua.match(/Android/i) != null) return true if (ua.match(/Edge\D?\d+/i) != null) 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==null)&&(verIE==null)&&(x64!==null)) return true else if (verFF !== null) { verFF = verFF[0].match(/\d+/) if ((verFF[0]>= 42)||(x64!==null)) return true } else if ( verOPR !== null) { verOPR = verOPR[0].match(/\d+/) if ( verOPR[0] >= 32 ) return true } else if ((verTrident==null)&&(verIE==null)) { var verChrome=ua.match(/Chrome\D?\d+/i) if ( verChrome !== null ) { verChrome = verChrome[0].match(/\d+/) if (verChrome[0]>=42) return true } } return false } catch(err) {return true} } //====页面引用CLodop云打印必须的JS文件：==== if (needCLodop()) { var head = document.head || document.getElementsByTagName("head")[0] || document.documentElement var oscript = document.createElement("script") oscript.src ="http://localhost:8000/CLodopfuncs.js?priority=1" head.insertBefore( oscript,head.firstChild ) //引用双端口(8000和18000）避免其中某个被占用： oscript = document.createElement("script") oscript.src ="http://localhost:18000/CLodopfuncs.js?priority=0" head.insertBefore( oscript,head.firstChild ) } //====获取LODOP对象的主过程：==== 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.exe' 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

href='CLodop_Setup_for_Win32NT.exe' target='_self'>执行升级</a>,升级后请刷新页面。</font>" var LODOP try{ var isIE = (navigator.userAgent.indexOf('MSIE')>=0) || (navigator.userAgent.indexOf('Trident')>=0) if (needCLodop()) { try{ LODOP=getCLodop()} catch(err) {} if (!LODOP && document.readyState!=="complete") { alert("C-Lodop没准备好，请稍后再试！") return } if (!LODOP) { // if (isIE) document.write(strCLodopInstall) else // document.documentElement.innerHTML=strCLodopInstall+document.documentElement.innerHTML // return } else { if (CLODOP.CVERSION<"3.0.0.2") { if (isIE) document.write(strCLodopUpdate) else document.documentElement.innerHTML=strCLodopUpdate+document.documentElement.innerHTML } if (oEMBED && oEMBED.parentNode) oEMBED.parentNode.removeChild(oEMBED) if (oOBJECT && oOBJECT.parentNode) oOBJECT.parentNode.removeChild(oOBJECT) } } else { var is64IE = isIE && (navigator.userAgent.indexOf('x64')>=0) //=====如果页面有Lodop就直接使用，没有则新建:========== if (oOBJECT!=undefined || oEMBED!=undefined) { if (isIE) LODOP=oOBJECT else LODOP=oEMBED } else if (CreatedOKLodop7766==null){ LODOP=document.createElement("object") LODOP.setAttribute("width",0) LODOP.setAttribute("height",0) LODOP.setAttribute("style","position:absoluteleft:0pxtop:-100pxwidth:0pxheight:0px") if (isIE) LODOP.setAttribute("classid","clsid:2105C259-1E0C-4534-8141-A753534CB4CA") else LODOP.setAttribute("type","application/x-print-lodop") document.documentElement.appendChild(LODOP) CreatedOKLodop7766=LODOP } else LODOP=CreatedOKLodop7766 //=====Lodop插件未安装时提示下载地址:========== if ((LODOP==null)||(typeof(LODOP.VERSION)=="undefined")) { if (navigator.userAgent.indexOf('Chrome')>=0) document.documentElement.innerHTML=strHtmChrome+document.documentElement.innerHTML if (navigator.userAgent.indexOf('Firefox')>=0) document.documentElement.innerHTML=strHtmFireFox+document.documentElement.innerHTML if (is64IE) document.write(strHtm64_Install) else if (isIE) document.write(strHtmInstall) else document.documentElement.innerHTML=strHtmInstall+document.documentElement.innerHTML return LODOP } } if (LODOP.VERSION<"6.0") { if (!needCLodop()){ if (is64IE) document.write(strHtm64_Update) else if (isIE) document.write(strHtmUpdate) else document.documentElement.innerHTML=strHtmUpdate+document.documentElement.innerHTML } return LODOP } //===如下空白位置适合调用统一功能(如注册语句、语言选择等):=== //LODOP.SET_LICENSES("北京XXXXX公司","8xxxxxxxxxxxxx5","","") //=========================================================== return LODOP } catch(err) {alert("getLodop出错:"+err)} }

2.在组件中引入上步骤的js文件，{ getLodop } 是上述代码中的一个方法

3.实例化打印对象

this.LODOP = getLodop() // 创建一个LODOP对象 let counter = this.LODOP.GET_PRINTER_COUNT() // 获取打印机个数 for (let i = 0; i < counter; i++) { this.printerList.push({ // 将打印机存入printerList数组中 name: this.LODOP.GET_PRINTER_NAME(i), value: i }) }

即可得到打印机列表 如下：

4.准备好要打印的html，我这里是根据后端传回的数据动态生成的HTML

var html = '' for (let d = 0; d < this.orderDocuments.length; d++) { html += ` <h4 style="text-align: center;">发货单</h4> <div style="margin-top: 16px;display: flex;align-items: center;justify-content: space-around;"> <div>订单编号:${this.orderDocuments[d].order_sn}</div> <div>成团时间:${this.orderDocuments[d].pay_time}</div> <div>收件人:${this.orderDocuments[d].receiver_phone}</div> <div>收件电话:${this.orderDocuments[d].receiver_phone}</div> </div> <table role="table" style="float:left;margin:0;padding:0px;width:100%;border:1px solid #000;"> <thead> <tr> <th style="border: 1px solid black" rowspan="1" type="header" name="goods_name">商品名称</th> <th style="border: 1px solid black" rowspan="1" type="header" name="goods_spec">规格</th> <th style="border: 1px solid black" rowspan="1" type="header" name="goods_price">单价(元)</th> <th style="border: 1px solid black" rowspan="1" type="header" name="goods_count">数量</th> <th style="border: 1px solid black" rowspan="1" type="header" name="goods_money">金额</th> </tr> </thead> <tbody class="chris-table-body"> ${this.orderDocuments[d].goods.map(i => { return `<tr class="chris-table-row first last" role="row"> <td style="border: 1px solid black" type="body" name="goods_name">${i.goods_name}</td> <td style="border: 1px solid black" type="body" name="goods_spec">${i.goods_spec}</td> <td style="border: 1px solid black" type="body" name="goods_price">${i.goods_price}</td> <td style="border: 1px solid black" type="body" name="goods_count">${i.goods_count}</td> <td style="border: 1px solid black" type="body" name="goods_money">${i.goods_money}</td> </tr>` })} </tbody> </table> <div style="margin: 8px; text-align: center" class="border"> <img :src="${this.orderDocuments[d].wpcode}" style="width: 100px;height: 100px;" alt=""> </div> ` } var body = '<body>' + html + '</body>'

5.生成好数据后进行打印项配置，并打印

_this.LODOP.PRINT_INIT('打印发货单') //打印初始化 _this.LODOP.SET_PRINTER_INDEX(_this.printer) //选择的打印机类型（注意这里是打印机下标，0开始的） _this.LODOP.SET_PRINT_STYLE('FontSize', 18) //设置对象风格 // this.LODOP.ADD_PRINT_TEXT(50, 521, 130, 39, this.description) //增加纯文本项 _this.LODOP.SET_PRINT_PAGESIZE(2, 0, 0, 'A4') //设定纸张大小 _this.LODOP.SET_PRINT_MODE('PRINT_PAGE_PERCENT', '55%')//设置缩放 _this.LODOP.SET_PREVIEW_WINDOW(2, 2, 0, 0, 0, '')//设置窗口 _this.LODOP.ADD_PRINT_HTM(88, 20, 2000, 2000, body) // 增加超文本项（打印内容即为body内容） // _this.LODOP.PREVIEW() // 设置预览（如果使用预览，每次打印前会弹出预览窗口，根据需要决定是否使用） _this.LODOP.PRINT()

6.打印效果如下

至此，一个简单的clodop就完成了，如有补充，请留言~~
