Question

我正在研究数据表中的一个简单的ajax示例，它无法正常工作，我无法解释它。我有一个简单的表格如下：

<table id="tblAddresses">
  <thead>
    <tr>
        <th>Street Address</th>
        <th>City</th>
        <th>State</th>
        <th>Zip Code</th>
    </tr>
 </thead>
 <tfoot>
    <tr>
        <th>Street Address</th>
        <th>City</th>
        <th>State</th>
        <th>Zip Code</th>
        </tr>
 </tfoot>
</table>

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，但文件是一条没有换行的长行）。

{"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：

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

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”。

我曾经多次使用ajax，但从未从静态数据文件加载。我在JSON或Javascript中找不到错误。

您以错误的方式绑定数据。您需要在ajax方法之后绑定列，例如bellow，

$("#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"}]
        });

希望它有所帮助！
