选择标记帮助器.NET Core到控制器 [英] Select-Tag Helper .NET Core to Controller

问题描述

我尝试使用提交"按钮提交标签选择，它正常工作，但是没有提交按钮怎么办?

I have tried to submit tag-select with 'submit' button and it worked properly but how about without submit button ?

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?

I want to send the value of tag-select directly to controller every time it changes without javascript. Is that possible ?

@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
}

推荐答案

尝试一下:

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