我是 ASP.NET Core Razor Pages 的新手。我已經使用 Visual Studio 2010 和 ASP.NET Core 應用程式的模板構建了一個簡單的解決方案
我在登錄頁面中添加了一個包含兩個選項的單選按鈕，用于提及性別選擇。我想根據單選按鈕中的選定選項有條件地回傳 RedirectionToPage。
如果用戶選擇男孩 添加密碼和電子郵件 --> 重定向到“./boysNames”頁面
如果用戶選擇 GIRL 添加密碼和電子郵件 --> 重定向到“./girlsNames”頁面
這是我的代碼：
登錄頁面中的單選按鈕
<div class="form-group ">
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1" checked>
<label class="form-check-label" for="inlineRadio1">Boy</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
<label class="form-check-label" for="inlineRadio2">Girl</label>
</div>
</div>

uj5u.com熱心網友回復：
您可以嘗試在 Pagemodel 中獲取單選按鈕的值，如果值為option1, return RedirectToPage("./boysNames");, 如果值為option2, return RedirectToPage("./girlsNames");。這是一個演示：
看法：
<form method="post">
<div class="form-group ">
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1" checked>
<label class="form-check-label" for="inlineRadio1">Boy</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
<label class="form-check-label" for="inlineRadio2">Girl</label>
</div>
</div>
...
<input type="submit" value="submit"/>
</form>
pagemodel（單選按鈕的值將被系結到inlineRadioOptions）：
[BindProperty]
public string inlineRadioOptions { get; set; }
public async Task<IActionResult> OnPostAsync(string returnUrl = null)
{
returnUrl ??= Url.Content("~/");
ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
if (ModelState.IsValid)
{
// This doesn't count login failures towards account lockout
// To enable password failures to trigger account lockout, set lockoutOnFailure: true lockoutOnFailure: false
var result = await _signInManager.PasswordSignInAsync(Input.Correo, Input.Contrase?a, Input.RememberMe, lockoutOnFailure: false); //I Think I have to add here the radio selection
if (result.Succeeded)
{
if (inlineRadioOptions == "option1")
{
_logger.LogInformation("BoysSelection.");
return RedirectToPage("./boysNames");
}
else {
_logger.LogInformation("Girls Selection.");
return RedirectToPage("./girlsNames");
}
}
}
// If we got this far, something failed, redisplay form
return Page();
}
