如何从数据表中获取文本框中的数据？

Question

我的JSON数据看起来像这样，我试图通过数据表发送它。

JSON数据：

{
  "data": [{
    "name": "name1",
    "value": "value1",
    "list": [{
      "sname": "sname1",
      "svalue": "svalue1"
    }, {
      "sname": "sname2",
      "svalue": "svalue2"
    }]
  }]
}

JQuery代码：

var pk =   $("#pk").val();                                                               
console.log(pk);
url="/register/search?id="+pk;
console.log(url);   
$('#largeTable').DataTable({
  "ajax" : url,   
  "bDestroy":true,
  "columns":[
    {"data": "name"},
    {"data": "value"},
    {"data": "list.sname"},
    {"data": "list.svalue"},
    {"data": null,"defaultContent":editview}
  ]
}); 

HTML code：

<div class="box-body">
  <table class="table table-striped table-bordered" id="largeTable" style="background-color: white;"  >
    <thead  style="background-color:#CCE5FF">
      <tr>
        <th>EName</th>
        <th>Value</th>
        <th>SuperiorName</th>                     
        <th>SValue</th>
        <th>action</th> 
      </tr>                    
    </thead>
  </table>            
</div>

我希望在html页面文本框下面获取数据表值。

<form class="form-horizontal" role="form" id="RegistrationForm" >
  <div class="col-md-6">
    <div class="form-group ">
      <label for="ename" class="col-md-4 control-label">EName</label>
      <div class="col-md-6">                                  
        <input type="text" class="form-control" id="ename"  name="ename" placeholder="EName" />
      </div>
    </div>                     
    <div class="form-group ">
      <label for="value" class="col-lg-4 control-label">Value</label>
      <div class="col-lg-6">
        <input type="text" class="form-control" id="value" placeholder="value"/>
      </div>
    </div>
    <div class="form-group ">
      <label for="sname" class="col-lg-4 control-label">Supr.Name</label>
      <div class="col-lg-6">
        <input type="text" class="form-control" id="sname"  name = "sname" placeholder="Supr.Name"/>
      </div>
    </div>
    <div class="form-group ">
      <label for="svalue" class="col-lg-4 control-label">SValue</label>
      <div class="col-lg-6">
        <input type="text" class="form-control" id="svalue"  name="svalue"  placeholder="SValue"/>
      </div>
    </div> </div>                                                                                    
</form>
