javascript - 为什么 Bootstrap 不调用事件类？

Question

我通过 jQuery Ajax 从 PHP 文件接收信息并循环该信息，如下所示。我需要它来调用 <tr class="active">并将它们放入 <tr><td> bootstrap 提供的格式。但不幸的是，这并没有发生。

有人有什么建议吗？谢谢:)

function getStudentList() {
     $.ajax({    //create an ajax request to load_page.php
       type: "GET",
       url: "getView.php",             
       dataType: "json",   //expect html to be returned                
       success: function(response){                    
          $.each(response, function(index, response){

          $( "#aaa" ).append('<tr class="active"><td>' + response['Student_ID'] + '</td><td>' + response['FirstName'] + "</td><td>" + response['LastName'] + "</td><td>" + response['Student_ID'] + "</td><td>" + response['Year'] + '</td></tr>');
        });

    },
     error: function(e) {
        //called when there is an error
        console.log("Error: " + e.message);
        }
    });
}

我建议你开始使用更好的IDE；我推荐PHPStorm。问题似乎出在您的引号语法上。检查这些区域:

你有:

<td>' + response['Student_ID'] + '</td>

应该是:

<td>' + response["Student_ID"] + '</td>

更好:

<td>' + response.Student_ID + '</td>
