Question

我是Jquery的新手，我有一个小任务，使用jquery ui对话框将json文件加载到datatable，我使用visual studio 2010来完成这项任务。

这是json代码：

{

"RELATIONMboSet":

{"rsStart":0,"rsCount":17,"RELATION":

[{"Attributes":{"RELATIONID":{"content":18,"resourceid":true},

"RELATIONNUM":{"content":"INCLUDES"},
"DESCRIPTION":{"content":"This is the container relationship for assets"},

使用下面的jquery ui对话框：

<div id ='legend-dialog' >
    <table id="legend_table" style="width:100%">
      <tr>
        <th>Relation Name</th>
        <th>Description</th> 
        <th>Type</th>
        <th>Color</th>
      </tr>
      <tr>
        <td>INCLUDES</td>
        <td>This is the container relationship for assets.</td> 
        <td>UNIDIRECTIONAL</td>
        <td><div class="legencolor1" style='background-color:#888;'></div></td>
      </tr>
      <tr>
        <td>RELATES</td>
        <td>Relates</td> 
        <td>BIDIRECTIONAL</td>
        <td><div class="legencolor2" style='background-color:#888;'></div></td>
      </tr>           
    </table>    
    <p style="margin-top:5px">  
    <button type="button" class="btn btn-warning btn-xs" id="closebtn" style="float:left; margin-left:5px">Close</button>
    <button type="button" class="btn btn-primary btn-xs" id="applybtn" style="float:right; margin-right:5px">Apply</button>
    </p>
</div>

关于如何解决这个问题的任何想法？

这似乎有效：

$(document).ready(function(){
    var table = $('#example').DataTable({
        "columns":[
            {
                "title":"Relation Name"
            },
            {
                "title":"Description"
            },
            {
                "title":"Type"
            },
            {
                "title":"Color",
                "render": function(){
                    return '<div class="legencolor1" style="background-color:#888;">&nbsp;</div>';
                }
            }
        ]
    });
    $.each(data.RELATIONMboSet.RELATION, function(k, v){
        table.row.add([
            v.Attributes.RELATIONNUM.content,
            v.Attributes.DESCRIPTION.content,
            v.Attributes.TYPE.content
        ]).draw();
    })
});

只要在jQuery文档就绪函数之前将您的数据块分配给名为data的变量。

我尝试在DataTable初始化脚本中使用数据作为数据源，但它不喜欢Attributes作为名称...工作JSFiddle：https://jsfiddle.net/annoyingmouse/hbs9p4us/

希望有所帮助。
