JSON结果仅包含一项 [英] JSON result containing only one item

问题描述

我可能会用json和javascript丢失某些内容.

I'm likely missing something with json and javascript.

[{"commentText":"Testing 123","userPosted":"maxfridbe"},
{"commentText":"Testing 23","userPosted":"maxfridbe"}]

有时候我会收到多个与此代码兼容的响应:

Sometimes I get multiple responses which works with this code:

function(data) 
        {
            var sel = this;

            jQuery.each(data,
                function()
                {
                    sel.append("<li>"+ this.userPosted+ "-" + this.commentText + "</li>");
                });          
        };

有时我只会收到一个破坏上面代码的响应:

Sometimes I only get one response which breaks the above code:

[{"commentText":"another test again welcom","userPosted":"maxfridbe"}]

我知道这是因为响应与列表的处理方式有所不同.

I know this is because the response is being treated differently than a list.

寻找答案，我得到了一些解决方法.任何解决方案将不胜感激.

Looking for the answer to this I get a bit of a runaround. Any solution would be greatly appreciated.

推荐答案

使用CMS解决方案使我意识到数据只是某种程度上的字符串:

Playing around with CMS's solution made me realize that data was just a string somehow so:

if (!jQuery.isArray(data))  data = eval(data);

之所以起作用，是因为那时数据是一个对象.不知道为什么有多个结果会为您评估.

worked because then the data was an object. Not sure why when there are multiple results it does an eval for you.
