【问题描述】：
我是淘汰赛的新手。我想将一个文本框绑定到一个视图模型。我有以下代码，但它不起作用。有人能指出我正确的方向吗。
我正在尝试将数据从我的视图模型发布到控制器，但值是空的，即使我已经在文本框中输入了值
<div class="container">
<form class="form-horizontal" id="ProviderForm" method="post">
<div class=" form-group">
<label for="Provider" class="control-label col-sm-2">PROVIDER :</label>
<div class="col-sm-8">
<div class="input-group">
<div class="input-group-btn">
<button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown">
<span class="caret"></span>
</button>
<ul id="demolist" class="dropdown-menu">
<li><a href="#">Doctor</a></li>
<li class="disabled"><a href="#">Facilities</a></li>
</ul>
</div>
<input type="text" id="datebox" data-bind="value: ProviderType" class="form-control" />
</div>
</div>
</div>
<div class=" form-group">
<label for="firstName" class="col-sm-2 control-label">First Name</label>
<div class="col-sm-8">
<input type="text" class="form-control" id="inputFirstName" data-bind="value: FirstName" placeholder="Enter the First Name">
</div>
</div>
<div class="form-group">
<label for="lastName" class="col-sm-2 control-label">Last Name</label>
<div class="col-sm-8">

<li class="disabled"><a href="#">D.O.</a></li>
</ul>
</div>
<input type="text" id="datebox2" data-bind="value: Certification" class="form-control" />
</div>
</div>
</div>
<div class="form-group">
<label for="Specialization" class="control-label col-sm-2">Specialization :</label>

</ul>
</div>
<input type="text" id="datebox3" data-bind="value: Specialization" class="form-control" />
</div>
</div>
</div>
<div class="form-group">
<label for="SSN" class="col-sm-2 control-label">SSN</label>
<div class="col-sm-8">
<input type="text" class="form-control" id="inputSSN" data-bind="value: SSN" placeholder="Enter your SSN">
</div>
</div>
<div class="form-group">
<label for="FacilityName" class="col-sm-2 control-label">Facility Name</label>
<div class="col-sm-8">
<input type="text" class="form-control" id="inputFacility" data-bind="textInput: FacilityName" placeholder="Enter your Facility">
</div>
</div>
<div class="form-group">
<label for="ContactNumber" class="col-sm-2 control-label">Contact Number</label>
<div class="col-sm-8">
<input type="text" maxlength="10" class="form-control" id="inputContactNum" data-bind="value: ContactNumber" placeholder="Enter your Facility">

</div>
</div>
<div class="form-actions span7 text-center">
<button type="submit" id="Submit" class="btn btn-primary btn-md ">Save</button>
<button type="reset" class="btn btn-primary btn-md ">Reset</button>
</div>
</form>
</div>
我的脚本
$("document").ready(function () {
$("#Submit").on("click",function(){
var Provider =
{
ProviderType: ko.observable(""),
FirstName: ko.observable(""),
Lastname: ko.observable(""),
Certification: ko.observable(""),
Specialization: ko.observable(""),
SSN: ko.observable(""),
ContactNumber: ko.observable(""),
ContactEmail: ko.observable(""),
FacilityName : ko.observable("")
}
ko.applyBindings(Provider);
$.ajax({
type: "POST",
url: "/PatientRegister/Create",
data : Provider
});
});
});
在控制器中，我使用这个提供者作为参数。
public ActionResult Create(Provider provider)
{
//....
}
目前provider字段为null，我也创建了一个Provider Class，参数名称相同
public class Provider
{
public string ProviderType { get; set; }
public string FirstName { get; set; }
public string Lastname { get; set; }
public string Certification { get; set; }
public string Specialization { get; set; }
public string SSN { get; set; }
public string ContactNumber { get; set;}
public string ContactEmail { get; set; }
public string FacilityName { get; set; }
}
