Question

我有点问题，我想问是否有可能，如果是的话。例如，您有一个用于租车预订的创建表单。

Car model containts information like:
brand,model,costPerHour, NumberOfSeats(how many seat 4,5,7,...)

在创建表单 - 下拉列表中：

<div class="editor-label">
  @Html.LabelFor(model => model.CarId, "Car")
</div>
<div class="editor-field">
  @Html.DropDownList("CarId", String.Empty)
  @Html.ValidationMessageFor(model => model.CarId)
</div>

在下拉列表中会有一个滑块，其中包含将要旅行的人数。

<div class="editor-label">
  @Html.LabelFor(model => model.PersonsInCar)
</div>
<div class="editor-field">
  @Html.EditorFor(model => model.PersonsInCar)
  @Html.ValidationMessageFor(model => model.PersonsInCar)
</div>

有没有办法限制PersonsInCar的编辑器，具体取决于Car.NumberOfSeats（从1到所选汽车的座位数）？谢谢你的帮助。

Answer 1

$.ajax({
    type: "GET",        //GET or POST or PUT or DELETE verb
    url: ajaxUrl,       // Location of the service
    data: "",       //Data sent to server in your case CarID Selected
    contentType: "",        // content type sent to server
    dataType: "json",   //Expected data format from server
    processdata: true,  //True or False
    success: function (json) {//On Successful service call
    var result = json.name;
    $("#dvAjax").html(result);
    },
    error: ServiceFailed    // When Service call fails
});

你必须在控制器中编写一个方法，在json中返回Number of Seats，这个方法接收CarID参数
