node 使用第三方api 生成 word 文檔之修改源碼實現需求

使用了 officegen 第三方 api 實現生成word 文檔，可是發現下劃線沒法知足需求。修改源碼以便後人踩坑,如下是個人一個demo，經過傳參數設置下劃線顏色以及高度。本demo 經過json 配置方式，還有api 調用方式實現方式，詳細能夠參考git 的例子
GITHUB Api地址: https://github.com/Ziv-Barber/officegen

var officegen = require('officegen');

var path = require('path');
var docx = officegen('docx');

var header = docx.getHeader().createP({
    align: ('center')
});

console.log('路徑為' + __dirname);

docx.createByJson(data)

//var pObj = docx.createTable(table, tableStyle);

out.on('error', function(err) {
    console.log(err);

var result = docx.generate(out);

找到源碼修改

修改代碼部分以下：gendocx.js 部分

else if ( objs_list[i].data[j].horizontal_line ) {
                        console.log(objs_list[i].data[j]);
                        var height=typeof objs_list[i].data[j].options.height=="string"?objs_list[i].data[j].options.height:".75";
                        var fillcolor=typeof objs_list[i].data[j].options.fillcolor=="string"?objs_list[i].data[j].options.fillcolor:"e0e0e0";
                        //outString += `<w:r><w:pict><v:rect o:spt="1" style="width:0;height:${height}pt" o:hralign="center" o:hrstd="t" o:hr="t" fillcolor="#${fillcolor}" stroked="f"/></w:pict></w:r>`;
                        outString += `<w:r><w:pict><v:rect o:spt="1" style="height:${height}pt;width:0pt;" fillcolor="#${fillcolor}" filled="t" stroked="f" coordsize="21600,21600" o:hr="t" o:hrstd="t" o:hrnoshade="t" o:hralign="center"/></w:pict></w:r>`;
                    // Bookmark start support:
                    }

docx-p.js 部分

MakeDocxP.prototype.addHorizontalLine = function (opt) {
    var newP = this;
    newP.data[newP.data.length] = { 'horizontal_line': true, options:opt||{} };
};

修改成傳參數設置其下滑線顏色跟高度最後附上效果圖：
