如果是用webform那不需要讨论,但asp.net mvc中一个表单只能提交到一个Action处理,相对比较麻烦点。
方法一:使用客户端脚本
比如我们在View中这样写:
<inputtype="submit"value="审核通过"onclick="this.form.action="<%=Url.Action("Action1")%>/><inputtype="submit"value="审核不通过"onclick="this.form.action="<%=Url.Action("Action2")%> /><inputtype="submit"value="返回"onclick="this.form.action="<%=Url.Action("Action3")%>" />在点击提交按钮时,先改变Form的action属性,使表单提交到按钮相应的action处理。
<input type="submit" value="审核通过" name="action" /><input type="submit" value="审核不通过" name="action"/><input type="submit" value="返回" name="action"/>然后在控制器中判断:
[HttpPost] public ActionResult Index(string action /* 其它参数*/) {if (action=="审核通过"){ //}else if (action=="审核不通过"){//}else{ //} }几年前写asp代码的时候经常用这样的方法…
[HttpPost][MultiButton("action1")]public ActionResult Action1(){ // return View();}[HttpPost][MultiButton("action2")]public ActionResult Action2(){ // return View();}在 View中:
<input type="submit" value="审核通过" name="action1" /><input type="submit" value="审核不通过" name="action2"/><input type="submit" value="返回" name="action3"/>此时,Controller已经无须依赖于按钮的Value值。
public class MultiButtonAttribute : ActionNameSelectorAttribute{ public string Name { get; set; } public MultiButtonAttribute(string name) {this.Name = name; } public override bool IsValidName(ControllerContext controllerContext,string actionName, System.Reflection.MethodInfo methodInfo) {if (string.IsNullOrEmpty(this.Name)){ return false;}return controllerContext.HttpContext.Request.Form.AllKeys.Contains(this.Name); }}方法四:改进
[HttpPost] [MultiButton(Name = "delete", Argument = "id")] public ActionResult Delete(string id) { var response = System.Web.HttpContext.Current.Response; response.Write("Delete action was invoked with " + id); return View(); }View:
<input type="submit" value="not important" name="delete" /><input type="submit" value="not important" name="delete:id" />MultiButtonAttribute定义:
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public class MultiButtonAttribute : ActionNameSelectorAttribute { public string Name { get; set; } public string Argument { get; set; } 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.Controller.ValueProvider[Argument] = new ValueProviderResult (value, value, null); } private bool KeyStartsWithButtonName(string key) { return key.StartsWith(Name, StringComparison.InvariantCultureIgnoreCase); } } //如果是在MVC 2.0中的话,将UpdateValueProviderIn方法改为:private void UpdateValueProviderIn(ControllerContext controllerContext, string value){ if (string.IsNullOrEmpty(Argument)) return; controllerContext.RouteData.Values[this.Argument] = value;}以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
