vue使用lodop列印控制元件實現瀏覽器相容列印的方法
阿新 • • 發佈：2021-02-10
前言
此控制元件直接進行列印底部會有水印，通過官網購買可以解決；
如不想購買，可先執行預覽，彈出預覽框進行列印；
需要用到的js檔案和api文件附後，請注意檢視。
首先需要在區域性或全域性引入LodopFuncs.js檔案
import {getLodop} from '../../../components/js/LodopFuncs'
方法中呼叫
print(){
let LODOP = getLodop();
LODOP.PRINT_INITA(0,800,1600,"列印庫位名稱");
LODOP.SET_PRINT_PAGESIZE(1,700,500,"") //設定紙張大小
LODOP.NewPage();//初始化
LODOP.SET_PRINT_MODE("RESELECT_PRINTER",true);
LODOP.ADD_PRINT_TEXT('10mm','50mm','30mm','20mm','iphone20Plus');//列印文字
LODOP.SET_PRINT_STYLEA(0,"FontSize",30);//字型樣式
LODOP.ADD_PRINT_LINE('10mm','35mm','40mm',1);//列印直線
LODOP.ADD_PRINT_BARCODE('10mm','2.5mm',"QRCode",'123456');//列印二維碼
LODOP.SET_PRINT_STYLEA(0,"AlignJustify",2);//二維碼樣式和規則
LODOP.SET_PRINTER_INDEXA("TSC TTP-244 Pro");//選擇印表機
// LODOP.PRINT_DESIGN()//開啟設定
// LODOP.PREVIEW(); //預覽
LODOP.PRINT() //直接列印
},LodopFuncs.js檔案
//==本JS是載入Lodop外掛及CLodop服務的綜合示例，可直接使用，建議看懂後融進自己頁面程式==
var CreatedOKLodopObject,CLodopIsLocal,CLodopJsState;
//==判斷是否需要CLodop(那些不支援外掛的瀏覽器):==
export function needCLodop() {
try {
var ua = navigator.userAgent;
if (ua.match(/Windows\sPhone/i))
return true;

verChrome = verChrome[0].match(/\d+/);
if (verChrome[0] >= 41)
return true;
}
}
return false;
} catch (err) {
return true;
}
}
//==引用CLodop的主JS,用雙埠8000和18000(以防其中一個被佔):==
if (needCLodop()) {
var head = document.head || document.getElementsByTagName("head")[0] || document.documentElement;

CLodopIsLocal = !!((JS1.src + JS2.src).match(/\/\/localho|\/\/127.0.0./i));
if (JS1.attachEvent) {
CLodopJsState = "loading";
var onChange = function(){
if (window.event.srcElement.readyState == 'loaded')
CLodopJsState = "complete";
};
JS1.attachEvent('onreadystatechange',onChange);
JS2.attachEvent('onreadystatechange',onChange);
}
}
