选择标记助手.NET Core到控制器

Question

我尝试使用“提交”按钮提交标记选择，它正常工作，但是没有提交按钮怎么办？

我希望每次更改时都将tag-select的值直接发送到控制器，而无需使用javascript。有可能吗？

@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

尝试一下：

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