javascript - 如果 html 表中的字符串 == 带有 Javascript 的内容则显示按钮

Question

仅当电子邮件 == 使用 JavaScript 的当前用户电子邮件地址时，我才尝试显示 x 按钮。

这就是我填充表格的方式

            var user = mymail@gnail.com
            function getOrders() {
                $.ajax({
                    type: "get",
                    url: "http://127.0.0.1:9000/get-orders",
                    success: function (data) {
                        response = data["code"];
                        data = data["data"];
                        var dataArray = data.orders;

                        for (var i = 0; i < dataArray.length; i++) {
                            tr = $('<tr/>');
                            tr.append("<td>" + "<button id='cancelOrderButton;'>X</button>" + "</td>");
                            tr.append("<td>" + dataArray[i].room + "</td>");
                            tr.append("<td>" + dataArray[i].user + "</td>");
                            tr.append("<td>" + dataArray[i].real_name + "</td>");


                            $('.table1').append(tr);
                        };
                    }
                });
            };

这是 HTML

                <table class="table1">
            <tr>
                <th></th>
                <th>Room</th>
                <th>Email</th>
                <th>Name</th>
            </tr>
        </table>

用引号将 mymail@gnail.com 括起来。我还在附加的 td 之间添加了一个 if 语句，它首先验证它们是否与硬编码的电子邮件匹配。

if (dataArray[i].user == currentUser) {
  tr.append("<td>" + "<button id='cancelOrderButton;'>X</button>" + "</td>");
}else{
  tr.append("<td></td>");
}

var currentUser = 'mymail@gnail.com'

function getOrders() {
  $.ajax({
    type: "get",
    url: "http://127.0.0.1:9000/get-orders",
    success: function(data) {
      response = data["code"];
      data = data["data"];
      var dataArray = data.orders;

      for (var i = 0; i < dataArray.length; i++) {
        tr = $('<tr/>');
        if (dataArray[i].user == currentUser) {
          tr.append("<td>" + "<button id='cancelOrderButton;'>X</button>" + "</td>");
        } else {
          tr.append("<td></td>");
        }
        tr.append("<td>" + dataArray[i].room + "</td>");
        tr.append("<td>" + dataArray[i].user + "</td>");
        tr.append("<td>" + dataArray[i].real_name + "</td>");


        $('.table1').append(tr);
      };
    }
  });
};

<table class="table1">
  <tr>
    <th></th>
    <th>Room</th>
    <th>Email</th>
    <th>Name</th>
  </tr>
</table>
