Jquery parseJSON失败-“意外的标记o”

Question

我想对一些JSON数据执行一个非常简单的AJAX请求，然后对其进行解析。我使用的代码如下：

$.get('/ajax/search/DSB.json', function (data) {
    searchData=$.parseJSON(data);
});

我收到一个错误：“意外的令牌o。”我已经验证了相关文件是有效的JSON。我也用谷歌搜索了答案--每个有这个问题的人都在向JSON解析器传递一个javascript对象，这显然是多余的。然而，我不确定这种情况下的问题是什么。有什么想法？

这是JSON，您可以自己检查它是否有效(它是有效的)。

删除你的.parseJSON(data)函数你的数据类型已经是json

如果joson是字符串格式，则此函数不起作用，但您的示例json类型是json，而不是字符串如果您使用parseJSON(data)，则返回此函数错误，此function worket仅适用于json string
