我在javascript中遇到了一个问题，我想在表格中显示一个列Success/Fail，但是他们在表格中显示了两列。它们不会在Success/Fail列中显示正确的值。

我该怎么办？有没有人帮我？

        var responseList = [{
            "summary": {
                "template_name": "test",
                "success": "2",
                "fail": "1",
            },
            "summary": {
                "template_name": "test",
                "success": "3",
                "fail": "2",
            },

        }];


        var table = document.querySelector('#my-table');
        var tbody = document.createElement('tbody');
        table.appendChild(tbody);


        for (var i = 0; i < responseList.length; i++) {

            var tr = tbody.insertRow();

            var summary = responseList[i]["summary"];
            console.log(summary);
            for (var key in summary) {
                if (summary.hasOwnProperty(key)) {
                    console.log(key + " -> " + summary[key]);
                    var td = tr.insertCell();
                    td.innerHTML = summary[key];
                      if(key == "success" || key == "fail"){
                      // console.log("success",summary[key]);
                      // console.log("fail",summary[key]);
                      var td = tr.insertCell();
                      td.innerHTML = `${summary[key]} Successful / ${summary[key]} Failed`;
                      }

                }
            }
        }

您的尝试对于它需要做的事情来说有点复杂，在循环中迭代摘要对象的键来构建表没有太大的价值。直接访问密钥要简单得多，就像我在下面做的那样。

var responseList = [
    {
        "template_name": "test",
        "success": "2",
        "fail": "1",
    },
    {
        "template_name": "test",
        "success": "3",
        "fail": "2",
    },
];

var table = document.querySelector('#my-table');
var tbody = document.createElement('tbody');
table.appendChild(tbody);

responseList.forEach(summary => {
  var tr = tbody.insertRow();
  tr.insertCell().innerHTML = `${summary.template_name}`
  tr.insertCell().innerHTML = `${summary.success}`
  tr.insertCell().innerHTML = `${summary.fail}`
  tr.insertCell().innerHTML = `${summary.success}/${summary.fail}`
})

                <th>Success/Fail</th>
