关于Ajax加载的Datatables.net错误

我正在研究数据表中的一个简单的ajax示例，它不起作用，我无法解释它。 我有一个简单的表格如下：

 
 
 
Street Address
 
City
 
State
 
Zip Code
 
 
 
 
 
Street Address
 
City
 
State
 
Zip Code
 
 
  

我有一个json数据源，其数据看起来像这样（我在这里显示了一点，但文件是一条长行，没有换行符）。

 {"data":[{"street":"19 Brook Avenue","city":"PASSAIC","state":"NJ","postcode":"07055"}, {"street":"27 Brook Avenue","city":"PASSAIC","state":"NJ","postcode":"07055"}, {"street":"31 Brook Avenue","city":"PASSAIC","state":"NJ","postcode":"07055"}, {"street":"35 Brook Avenue","city":"PASSAIC","state":"NJ","postcode":"07055"}, {"street":"39 Brook Avenue","city":"PASSAIC","state":"NJ","postcode":"07055"}, {"street":"49 Brook Avenue","city":"PASSAIC","state":"NJ","postcode":"07055"}]} 

最后，我将它加载到我的文档就绪函数中：

  $(document).ready(function(){ $("#tblAddresses").DataTable({ "ajax" : { "url" : "/json/07055.json", "columns" : [{"data":"street"}, {"data":"city"}, {"data":"state"}, {"data":"postcode"}] } }); });  

当我加载页面时，我看到了ajax调用。 我可以看到浏览器接受的数据，但DataTables给了我一个错误：

DataTables警告：table id = tblAddresses – 第0行第0列请求的未知参数“0”。

尽管从未从静态数据文件加载，但我曾多次使用过ajax。 我在JSON或Javascript中找不到错误。

您以错误的方式绑定数据。 你需要在ajax方法之后绑定列，比如下面的，

 $("#tblAddresses").DataTable({ "ajax" : { "url" : "/json/07055.json", "type": "Get" }, //Here end of ajax method. Now you can bind the columns "columns" : [{"data":"street"}, {"data":"city"}, {"data":"state"}, {"data":"postcode"}] }); 

希望能帮助到你！
