因为electron集成的客户端并不像浏览器那样自带打印功能,然后查了electron的打印,资料太少,什么静默打印乱七八糟的看不太懂,好像也没有预览的功能。。然后我找到了lodop控件,实现了打印功能

 

步骤一:到官网下载lodop,安装到电脑。

下载地址:http://www.lodop.net/download.html

 

步骤二:修改LodopFuncs.js源码,其实很简单,就是改为es6的模块化语法,方便在vue项目中引用而已。也就是在每个function前加上export ,具体如下

var CreatedOKLodop7766 = null, CLodopIsLocal;

//====判断是否需要 Web打印服务CLodop:===
//===(不支持插件的浏览器版本需要用它)===
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;
    }
}

//====页面引用CLodop云打印必须的JS文件,用双端口(8000和18000)避免其中某个被占用:====
if (needCLodop()) {
    var src1 = "http://localhost:8000/CLodopfuncs.js?priority=1";
    var src2 = "http://localhost:18000/CLodopfuncs.js?priority=0";

    var head = document.head || document.getElementsByTagName("head")[0] || document.documentElement;
    var oscript = document.createElement("script");
    oscript.src = src1;
    head.insertBefore(oscript, head.firstChild);
    oscript = document.createElement("script");
    oscript.src = src2;
    head.insertBefore(oscript, head.firstChild);
    CLodopIsLocal = !!((src1 + src2).match(/\/\/localho|\/\/127.0.0./i));
}

//====获取LODOP对象的主过程:====

                return;
            }
            if (!LODOP) {
                document.body.innerHTML = strCLodopInstall_1 + (CLodopIsLocal ? strCLodopInstall_2 : "") + strCLodopInstall_3 + document.body.innerHTML;
                return;
            } else {

            //=====如果页面有Lodop就直接使用,没有则新建:==========
            if (oOBJECT || oEMBED) {
                if (isIE)
                    LODOP = oOBJECT;
                else
                    LODOP = oEMBED;
            } else if (!CreatedOKLodop7766) {

                else
                    LODOP.setAttribute("type", "application/x-print-lodop");
                document.documentElement.appendChild(LODOP);
                CreatedOKLodop7766 = LODOP;

            if ((!LODOP) || (!LODOP.VERSION)) {

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

步骤三:就是在组件引入LodopFuncs.js啦

vue相应组件的script代码

<script>
    import {getLodop} from "../../../config/LodopFuncs";

    export default {
        name: "PrintDetailDialog",
        props:{
            PrintDetailDialogVisible:{
                type:Boolean,
                default:null
            }
        },
        data () {
            return {
                showClose:false,
                tableData:{
                    one:'扭力扳手',
                    two:'aaaa',
                    three:'2019-04-23 10:12:30',
                    four:'1111',
                    five:12,
                    six:8,
                    seven:666,
                    eight:353,
                    nine:2312,
                    mark:'已领用已领用'
                }
            }
        },
        methods:{
            handlePrintBtnClick () {
                // this.$print(this.$refs.printContent);
            },
            printPdf() {
                let  LODOP = getLodop();
                var strBodyStyle = '<link href="../../../assets/css/print.css" type="text/css" rel="stylesheet">';
                var strTableHtml = "<head>"+strBodyStyle+"</head><body>"+document.getElementById('PrintDetailTable').innerHTML+"</body>";
                LODOP.PRINT_INIT("订货单");
                LODOP.SET_PRINT_STYLE("FontSize", 18);
                LODOP.SET_PRINT_STYLE("Bold", 1);
                // LODOP.ADD_PRINT_TEXT(50, 231, 500, 39, "打印页面部分内容");
                LODOP.ADD_PRINT_HTM(0, "5%", "90%", "100%",strTableHtml);
                //参数按顺序分别为,上下间距,左右间距,宽度,高度  

//        LODOP.PRINT();
                LODOP.PREVIEW();
            }
        }
    }
</script>

template部分如下 

 

到了这步,就可以打印预览了,

 

重点来了!!!!!

 

如果你写的外联样式,你会发现样式不生效,哈哈

所以样式写内联。。

 

我目前没有找到外联样式的解决方法。。搜到的方法都试了就是木有效果。。。哪位亲知道引用外联样式的方法告诉一下我,多谢啦!
