$.getJSON('jsondata' , function(data) {
    var tbl_body = "";
    $.each(jsondata.seats, function() {
        var tbl_row = "";
        $.each(this, function(k , v) {
            tbl_row += "<td>"+v+"</td>";
        });
        tbl_body += "<tr>"+tbl_row+"</tr>";                 
    });
    $("#plan").html(tbl_body);
});

最后的函数在使用座位布局方面工作正常，但是，我需要将保存的信息作为函数生成的 sseatPrice的类添加。td我已经尝试基本上复制最后一个函数，但对于seatPrice对象并将其附加到表中，但这似乎不起作用。关于我将如何解决这个问题的任何建议？

您的代码存在一些问题。$.getJSON()如果您已经拥有数据，为什么还需要jsondata？如果你真的是从 AJAX 调用中获取这些数据，那很好，但是你需要data在函数中引用，而不是jsondata，或者将参数重命名为匿名函数。

传递给函数的第一个参数$.each()是数组的索引。您可以使用它来获取seatPrice相同索引的：

$.each(jsondata.seats, function (j, d) {
    var tbl_row = "";
    $.each(this, function (k, v) {
        var seatPrice = jsondata.seatPrice[j][k];
        var seatPriceClass = '';
        if(seatPrice == "0") {
             seatPriceClass = "notawesome";  
        } else if(seatPrice == "1") {
             seatPriceClass = "awesome";   
        } else {
             seatPriceClass = "none";   
        }
        tbl_row += "<td class='"+seatPriceClass+"'>" + v + "</td>";
    });
    tbl_body += "<tr>" + tbl_row + "</tr>";
});

似乎您使用 $.each() 循环使问题复杂化。正如 popnoodles 所说，您可以使用香草 for 循环。

这是你想要的吗？

$.getJSON('jsondata' , function(data) {
    var tbl_body = "";
    var tbl_row = "";

    for (var i in data.seats){
        tbl_row += "<td>"+i+"</td>";
    }


    for (var i in data.seatPrice){
        tbl_row += '<td class="' + i + '">this is a td</td>';
    }

    tbl_body += "<tr>"+tbl_row+"</tr>";   

    $("#plan").html(tbl_body);
});
