在jquery函数中，如何附加对象。价值观

这里的student是一个对象，包含值name、admissionNo等

 $('<td></td>').val(item['id']).html(item['student.name'])

---

你想用

$（''）.val（项['id']）

做什么？表格单元格没有值。共享json结构您的追加语法错误，缺少逗号。使用控制台调试代码怎么样？所以已经完成了一次编辑，删除了错误的附加语法…我喜欢这种方法。在不知道从对

selectTestStudent.html

的请求返回的JSON结构的情况下，这只是在黑暗中随机拍摄的，并不能帮助人们学会如何自己调试问题。@Rob Baillie:这不是随机拍摄的，你看提问者使用的是项目[“student.name”]。我的建议是这样的。我的理念是人们在尝试了很多之后才来到这里。他们从新的角度受益。他们迟早会学会的。

function onTestStudentChange()  {
    $.ajax({
        type : 'POST',
        dataType : 'json',
        url : '/sample/selectTestStudent.html',
        data : ({
                 id : $('#test').val()
    }),
        success : function(responseData) {
            if (responseData != null) {                       
                $('#studentTest').find('td').remove().end().append('').val('-1');
                $.each(responseData,function(index, item) {                         
                    $('#studentTest').append(
                        $('<td></td>').val(item['id']).html(item['student.name']),                          
                        $('<tr></tr>').val(item['id']).html(item['']) );
                    alert("Alert"+item['student.name']);
                });
            } else {                                 
                   $('#studentTest').find('td').remove().end().append(
                         '<td th:text="${student}"></td>').val('-1');
            }
        }
    });
}
