MVC页面上多个提交按钮提交到不同的Action

使用mvc扩展类,ActionNameAttribute方法如下:

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public class MultiButtonAttribute : ActionNameSelectorAttribute { public string Name { get; set; } public string Argument { get; set; } public MultiButtonAttribute(string name) { this.Name = name; } public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo) { var key = ButtonKeyFrom(controllerContext); var keyIsValid = IsValid(key); if (keyIsValid) { UpdateValueProviderIn(controllerContext, ValueFrom(key)); } return keyIsValid; } private string ButtonKeyFrom(ControllerContext controllerContext) { var keys = controllerContext.HttpContext.Request.Params.AllKeys; return keys.FirstOrDefault(KeyStartsWithButtonName); } private static bool IsValid(string key) { return key != null; } private static string ValueFrom(string key) { var parts = key.Split(":".ToCharArray()); return parts.Length < 2 ? null : parts[1]; } private void UpdateValueProviderIn(ControllerContext controllerContext, string value) { if (string.IsNullOrEmpty(Argument)) return; controllerContext.RouteData.Values[this.Argument] = value; } private bool KeyStartsWithButtonName(string key) { return key.StartsWith(Name, StringComparison.InvariantCultureIgnoreCase); } }

Controller:

[HttpPost] [MultiButton(Name = "delete", Argument = "id")] public ActionResult Delete(string id) { return View(); } 

或者

 [HttpPost] [MultiButton("btnSearch")] public ActionResult Index(AttendanceList model) { return View(model); }

View:

<input type="submit" value="查询" name="btnSearch" /><input type="submit" value="删除" name="delete:id" />
