如果我用JS定义了一个对象:

var j={"name":"binchen"};

如何将对象转换为JSON？输出字符串应为:

'{"name":"binchen"}'

我正在尝试创建以下内容:

var employees = {"accounting": [   // accounting is an array in employees.
                    { "firstName" : "John",  // First element
                      "lastName"  : "Doe",
                      "age"       : 23 },

                    { "firstName" : "Mary",  // Second Element
                      "lastName"  : "Smith",
                      "age"       : 32 }
                  ] // End "accounting" array.                                  

    } // End Employees

我开始了

 var employees = new Array();

如何动态继续创建数组(可能firstName随变量而变化)？我似乎没有得到嵌套数组.
