javascript - 使用变量作为 JSON 的键

Question

我的 json 是这样的: `

{
    "isfahan": [

    {  
        "id"   : "1",
        "city" : "ahar",                
        "top"  : "35%",
        "left" : "54%"

    },
    {  
        "id"   : "2",
        "city" : "marand",              
        "top"  : "35%",
        "left" : "54%"

    },
    {  
        "id"   : "3",
        "city" : "miane",               
        "top"  : "35%",
        "left" : "54%"

    }

],

"azerbaijan": [

    {  
        "id"   : "3",
        "city" : "miane",               
        "top"  : "35%",
        "left" : "54%"

    },
    {  
        "id"   : "3",
        "city" : "miane",               
        "top"  : "35%",
        "left" : "54%"

    }
],

"ardabil": [

    {  
        "id"   : "3",
        "city" : "miane",               
        "top"  : "35%",
        "left" : "54%"

    },
    {  
        "id"   : "3",
        "city" : "miane",               
        "top"  : "35%",
        "left" : "54%"

    },
    {  
        "id"   : "3",
        "city" : "miane",               
        "top"  : "35%",
        "left" : "54%"

    },
    {  
        "id"   : "3",
        "city" : "miane",               
        "top"  : "35%",
        "left" : "54%"

    }
]
      }

为了获取 JSON 对象，我将使用这样的:

                var pulse_state = $('#state_var').html();

                $.getJSON("data/pulse.json").done(function(data){

                        localStorage.setItem("data", JSON.stringify(data));
                        $.each(data.isfahan, function(index, value){

                            $(".cd-points-container").append(
                               "<li class='cd-single-point' style='top:"+value.top+"; left:"+value.left+";'><a class='cd-img-replace' href='#0'>اطلاعات بیشتر</a><div class='cd-more-info cd-left'><h2>"+ value.city + "</h2><p>"+ value.sepah_text +"</p><a href='#0' class='cd-close-info cd-img-replace'>Close</a></div></li><!-- .cd-single-point -->"

                            );

                        });
                        //end each function 

如您所见，如果我使用 data.isfahan 获取数组，一切正常，但如果我将 data.isfahan 更改为“data.pulse_state”，则会出错!!!!!

我的意思是我想使用名为 data.pulse_state 的变量，然后获取 JSON 对象，

你能帮我一下吗？

尝试

data[pulse_state]

而不是data.pulse_state。
