Javascript / JQuery AJAX无法解析AJAX响应

我知道有关于此的帖子,但我似乎无法找到它们。这是我愚蠢的地方:

我有一个用于id和整数的AJAX resqueting(稍后将在DOM上应用保证金)

以下是请求:

$(function(){
    $("#divAccordion").accordion({
    //Accordion options here, not relevant
    }).sortable({
    //Other sortable options here, not relevant
    //This is the important part:
        update:
            function(event, ui){
                var data = $(this).sortable('toArray');
                $.ajax({
                    url:"prc.php",
                    type:"POST",
                    dataType:'JSON',/*--Added this also--*/
                    data:{sort:data},
                    contentType : "application/x-www-form-urlencoded;charset=UTF-8"
                }).done(
                    function(margin){
                        console.log(margin);//This log [sebastien20140804130001:45, sebastien20140804130002:30]
                        for(key in margin){
                            console.log(key+"=>"+margin[key]);
                        }
                    }
                );
            }
    });
});

以下是我在控制台中获得的内容:

[sebastien20140804130001:45, sebastien20140804130002:30]
0=>[
1=>s
2=>e
3=>b
4=>a
...

看到问题?我的响应(margin)是一个字符串,我的for循环遍历每个char。 我期待这样的事情:

[sebastien20140804130001:45, sebastien20140804130002:30]
sebastien20140804130001=>45
sebastien20140804130002=>30

只是一个侧面说明我无法知道我的关键/价值'如果ID将相互跟随(数字顺序),我将不会收到([ID:MARGIN_TO_APPLY])

我的目标是能够遍历每个键/值'配对并应用这样的东西:

$('#'+key).css('margin-left', value);

如果您需要任何其他信息,请在我将提供的评论中提问。

谢谢!

2 个答案:

答案 0 :(得分:2)

  1. 响应不是有效的JSON(规范:http://json.org/)。它发送一个数组,但每个元素都不是有效的对象。它应该是这样的:

    [{" sebastien20140804130001" :45},{" sebastien20140804130002":30}]

  2. 收到回复后,您必须执行JSON.parse(response)转换为JSON对象,或使用dataType: 'json'配置,以便jQuery自动为您执行此操作。

答案 1 :(得分:0)

这是非常错误的,你应该以任何方式将你的数据结构化为有效的json并遵循Rajkumar Madhuram的答案,但是你在这里,作为regEx中的exex:

function(margin){
    var values = margin.match(/(\w+:\d+)+/);
    var keyValues = [];
    for (var i=0 ; i< values.length; i++) {
        var keyValue = values[i].split(":");
        keyValues.push({ key: keyValue[0], value: keyValue[1] });
    }
    // now you have an array with key-value pairs;
}
