HTML使用DOM对象获取Table数据

let paramAll = [];
let tableObj = document.getElementById("tableData").getElementsByClassName("item_tr"); // 找到需要获取数据的tr行
        for (let i = 0; i < tableObj.length; i++) {
            let getOnceFeeValueJson = {};
            let xh = (i + 1);
            let spmc = tableObj[i].cells[1].textContent; // td中文本数据
            let spjd = tableObj[i].cells[2].getElementsByClassName("form-control")[0].value; // td中select下拉选中数据value
            let spjdname = tableObj[i].cells[2].getElementsByClassName("form-control")[0].options[spjd].text; // td中select下拉选中数据label
            let gzd = tableObj[i].cells[3].getElementsByClassName("form-control")[0].value;
            let gzdname = tableObj[i].cells[3].getElementsByClassName("form-control")[0].options[gzd].text;
            let zl = tableObj[i].cells[4].getElementsByClassName("form-control")[0].value;
            let zlname = tableObj[i].cells[4].getElementsByClassName("form-control")[0].options[zl].text;
            let spbz = tableObj[i].cells[5].getElementsByTagName("input")[0].value; // td中input输入数据
            let ysbz = tableObj[i].cells[6].getElementsByTagName("input")[0].value;
            paramAll.push({ xh, spmc, spjdname, gzdname, zlname, spbz, ysbz });
        }
