我也是搜索的答案 给你总结一下

var html =
    "<p><tr style='height:21.2px'><td align='left'>${goods.goodsName}</td></tr> <tr style='height:21.2px'><td align='left'>${goods.goodsName2}</td></tr> <tr style='height:21.2px'><td align='left'>${goods.goodsName3}</td></tr></p><p><tr style='height:21.2px'><td align='left'>${goods.goodsName}</td></tr> <tr style='height:21.2px'><td align='left'>${goods.goodsName2}</td></tr> <tr style='height:21.2px'><td align='left'>${goods.goodsName3}</td></tr></p>";
// 1, 找到tr 获取标签内的内容
//var str = html.match(/(.)+(?=<\/tr>)/gim);

//var str = html.match(/[^\<]+(?=<\/tr>)/gim);
//console.log("str: ", str);

var str2 = html.match(/(\<tr)+([\s\S]*)+(?=<\/tr>)/gim);
console.log("str2: ", str2);

var str = /(\<tr)+([\s\S]*)+(?=<\/tr>)/gim.exec(html);
console.log("str: ", str);

// 2, 找到td 获取标签内的内容
// 获取 td 的内容
var strAry = str2[0].match(/[^><]+(?=<\/td>)/gim);

strAry.map((v) => {
    let reg = /(\${goods\.(.*?)})/gim;
    var arr = reg.exec(v);
    console.log("arr: ", arr);
    console.log("key: ", arr[2]);
    if (arr[2] === "goodsName") {
        console.log("替换前的内容: ", v);
        var strr = v.replace(reg, "替换的内容");
        console.log("strr: ", strr);
        //str2.replace("${goods.goodsName}", 111);
        //console.log("str2: ", str2);
    }
});




// 3, 捕获 替换
str2[0].replace(/\$\{goods.goodsName\}/gim, 111);
