Select-Tag Helper .NET Core 到控制器

Question

我尝试使用“提交”按钮提交标签选择并且它工作正常但是没有提交按钮怎么样？我想每次在没有 JavaScript 的情况下更改标签选择的值时直接将其发送到控制器。那可能吗 ？@model MyViewModel<form asp-controller="Home" asp-action="Create">    <select asp-for="EmployeeId" asp-items="@(new SelectList(Model.EmployeesList,"Id","FullName"))">        <option>Please select one</option>    </select></form>[HttpPost]public IActionResult Create(MyViewModel model){    //check model.EmployeeId     //to do : Save and redirect}

Answer 1

尝试这个：

<select asp-for="EmployeeId" asp-items="@(new SelectList(Model.EmployeesList,"Id","FullName"))" onchange="this.form.submit()">
    ...</select>
