我遇到一个错误，即'JSON无法解析'。这是由JSON格式错误引起的。

function aj() {
    $('#accounting').dataTable({

        'bServerSide': true,

'JSON无法解析'。这是由JSON引起的 enter image description here 你能指导我怎么做才能纠正它吗？

----------------------------------------------错误发生了

我改变了建议的JSON的一部分后

aoColumns = [
{"mData":"count"},{"mData":"AccountID"},
{"mData":"Debit"},{"mData":"Credit"},
{ "mData": "CurrencyID"},
{"mData":"Date"},
{"mData":"Terms"},
{"mData":"Actions"}
]

以下部分代码不起作用

3 个答案:

答案 0 :(得分：0)

'sAjaxSource'url必须包含json编码数据

使用http://jsonlint.com/验证json数据

适用于我的版本：

的jquery-1.7.1，    jquery.dataTables 1.9.0

答案 1 :(得分：0)

您的aoColumns json格式错误请删除空格并使用以下格式：

aoColumns = [
{"mData":"count"},{"mData":"AccountID"},
{"mData":"Debit"},{"mData":"Credit"},
{ "mData": "CurrencyID"},
{"mData":"Date"},
{"mData":"Terms"},
{"mData":"Actions"}
]

答案 2 :(得分：0)

问题似乎是这部分：+ $（'＃users'）。val（）

当我把它留下来时，json格式似乎有效，如果我用在线json阅读器检查它（我使用http://jsonviewer.stack.hu/但有很多）。

可能是的原因是你不能在json字符串中添加javascript / jquery代码。
