如何在SweetAlert中显示值而不是对象

Question

我使用带有html attr的甜蜜警报库，但我需要在swal中显示循环中的一些值，我得到的只是[object object]我不知道为什么。

这是我的代码：

$(".track_details").click(function () {
    var data = $(this).data('val');
    swal({
        title: "HTML <small>Title</small>!",
        text: "<div class='row'>\
        <div class='col-md-2'>\
        <strong>\
            <span>Message</span>\
        </strong>\
    </div>\
        <div class='col-md-2'>\
        <strong>\
            <span>Status</span>\
        </strong>\
    </div>\
    <div class='col-md-2'>\
        <strong>\
            <span>Datetime</span>\
        </strong>\
    </div>\
    <div class='col-md-2'>\
        <strong>\
            <span>City</span>\
        </strong>\
    </div>\
   <div class='col-md-1'>\
        <strong>\
            <span>State</span>\
        </strong>\
    </div>\
    <div class='col-md-1'>\
        <strong>\
            <span>Zip</span>\
        </strong>\
    </div>\
     <div class='col-md-2'>\
        <strong>\
            <span>Country</span>\
        </strong>\
    </div>\
    </div> <div class='row my_tracking_swal'></div> \
    " + $.each(data, function (index, val) {
            $("<div class='col-md-2'>\
        <strong>\
            <span>" + val.tracking_status + "</span>\
        </strong>\
    </div>\
        <div class='col-md-2'>\
        <strong>\
            <span>" + val.tracking_status + "</span>\
        </strong>\
    </div>\
    <div class='col-md-2'>\
        <strong>\
            <span>" + val.tracking_status + "</span>\
        </strong>\
    </div>\
    <div class='col-md-2'>\
        <strong>\
            <span>" + val.tracking_status + "</span>\
        </strong>\
    </div>\
    <div class='col-md-1'>\
    <strong>\
            <span>" + val.tracking_status + "</span>\
        </strong>\
    </div>\
    <div class='col-md-1'>\
       <strong>\
            <span>" + val.tracking_status + "</span>\
        </strong>\
    </div>\
    <div class='col-md-2' >\
     <strong>\
            <span>" + val.tracking_status + "</span>\
        </strong>\
    </div>\
    ").appendTo(".my_tracking_swal");
        }),

        html: true
    }) ;

});

我的数据值看起来像[{'tracking_status':'value'},{'tracking_status':'value'},{'tracking_status':'value'}]
