Javascript 使用敲除将文本框中的输入值绑定到服务器。

使用knockout，我希望接受提交的值，并使用ko.toJson将它们发送到服务器。我是个新手，我确信我有一些语法问题。更简单地说，我希望我的提交按钮保存文本框中的值，并将它们保存到服务器。 这是我的小提琴

您可以将

submit

和

reset

按钮绑定到视图模型内的函数。然后在您的数据模型中创建一个

submit

函数，您可以在其中创建一个数据对象，在此上下文中，我将其定义为

Agent

，并将其传递给一个ajax调用，在该调用中，您可以用发布数据的控制器的路径替换

/echo/json

我对您的html做了一些细微的更改，以跟踪

可观察到的内容

<div class='Agent Form'>   
<p>First name: <input data-bind='value: firstName' /></p> 
<p>Last name: <input data-bind='value: lastName' /></p> 
<p>Agent NPN: <input data-bind='value: npn' /></p>
<p>Lead Location: <input data-bind='value: leadLocation' />(City, State, Zip)</p>
<p>Requested Lead Delivery Time/Date: <input data-bind='value: leadDeliveryTime' /></p>
<p>Leads Requested: 
    <select>
      <option value="1">1</option>
      <option value="2">2</option>
      <option value="3">3</option>
      <option value="4">4</option>
      <option value="5">5</option>
      <option value="10">10</option>
    </select> </p>
<p>Email Address: <input data-bind='value: emailAddress' /></p>
</div>
<div>
    <button data-bind = "click: submit" >Submit</button>
    <button data-bind = "click: reset" >Reset</button>
</div>

如何将ajax回调数据访问到laravel控制器：ajax回调数据是（数据：代理）。我尝试将其作为echo$\u POST['FirstName']使用，但无法访问。。。。

 var ViewModel = function(first, last, NPN, leadlocation, leaddeliverytime, EmailAddress) {
this.firstName = ko.observable(first);
this.lastName = ko.observable(last);
this.NPN = ko.observable(NPN);
this.leadlocation = ko.observable(leadlocation);
this.leaddeliverytime = ko.observable(leaddeliverytime);
this.EmailAddress = ko.observable(EmailAddress);

};
var jsonData = ko.toJson(viewModel);

<div class='Agent Form'>   
<p>First name: <input data-bind='value: firstName' /></p> 
<p>Last name: <input data-bind='value: lastName' /></p> 
<p>Agent NPN: <input data-bind='value: npn' /></p>
<p>Lead Location: <input data-bind='value: leadLocation' />(City, State, Zip)</p>
<p>Requested Lead Delivery Time/Date: <input data-bind='value: leadDeliveryTime' /></p>
<p>Leads Requested: 
    <select>
      <option value="1">1</option>
      <option value="2">2</option>
      <option value="3">3</option>
      <option value="4">4</option>
      <option value="5">5</option>
      <option value="10">10</option>
    </select> </p>
<p>Email Address: <input data-bind='value: emailAddress' /></p>
</div>
<div>
    <button data-bind = "click: submit" >Submit</button>
    <button data-bind = "click: reset" >Reset</button>
</div>
