问题描述

我正在申请，我有一个文本框和一个输入文本并按Enter的按钮，它应该将电子邮件发送到输入的电子邮件地址.我使用类似
的jquery keydown事件来执行此操作

I am making an application,i have a textbox and a button on entering text and pressing enter,it should send email to the entered email address. I doing this with jquery keydown event like

$("#txtverfyemail").live("keydown", function (event) {
        if (event.keyCode == '13') {         
            SendEmail();       
        }
    });


 function SendEmail() {
        email = $('#txtverfyemail').val();
        a = true;
        if (email == "" || email == null) {
            ErrorDivText('Enter email address');
            a = false;
        }
        if (a) {
            if (!validateEmail(email)) {
                ErrorDivText('Enter a valid email address');               
            }
            else {
                VerifyEmail(email);
            }
        }
    }

我的控制器名称是UserRegistration，我要重定向的操作是VerifyEmail，当我输入无效的电子邮件时，它会检查有效的电子邮件并显示错误消息msg，但突然出现错误IControllerFactory"Web.Mvc.SpringControllerFactory"没有为该控制器返回控制器名称为"VerifyEmail".

当我看到URL时，它变成http:\ localhost:4000 \ VerifyEmail \ UserRegistration

如果我输入有效的电子邮件，则会出现相同的错误，它会向电子邮件发送成功的消息msg，然后突然出现错误，我想知道将控制器名称与Actionname交换的方式和位置，即使在我未命中控制器的情况下，

My Controller name is UserRegistration and the action i am redirecting is VerifyEmail, When i enter an invalid email it checks for valid email and print error msg but suddenly gives error The IControllerFactory ''Web.Mvc.SpringControllerFactory'' did not return a controller for the name ''VerifyEmail''.

and when i see URL it becomes http:\localhost:4000\VerifyEmail\UserRegistration

The same error is arising if i enter a valid email,it sends email display success msg then suddenly gives error i am wondering how and where it is swaping controller''s name with Actionname,Even in the situation when i am not hitting controller

推荐答案

(" ) .live(" ，函数(事件){ 如果(事件 .keyCode == ' 13'){ 发送电子邮件(); } }); 函数SendEmail(){ email =

("#txtverfyemail").live("keydown", function (event) { if (event.keyCode == '13') { SendEmail(); } }); function SendEmail() { email =

(' #txtverfyemail').val( ); a = true ; 如果(电子邮件== " | | email == 空){ ErrorDivText(' 输入电子邮件地址'); a = false ; } 如果(a){ 如果(！validateEmail(email)){ ErrorDivText(' 输入有效的电子邮件地址')； } 其他 { VerifyEmail(email); } } }

('#txtverfyemail').val(); a = true; if (email == "" || email == null) { ErrorDivText('Enter email address'); a = false; } if (a) { if (!validateEmail(email)) { ErrorDivText('Enter a valid email address'); } else { VerifyEmail(email); } } }

我的控制器名称是UserRegistration，我要重定向的操作是VerifyEmail，当我输入无效的电子邮件时，它会检查有效的电子邮件并显示错误消息msg，但突然出现错误IControllerFactory"Web.Mvc.SpringControllerFactory"没有为该控制器返回控制器名称为"VerifyEmail".

当我看到URL时，它变成http:\ localhost:4000 \ VerifyEmail \ UserRegistration

如果我输入有效的电子邮件，则会出现相同的错误，它会发送成功的电子邮件显示消息，然后突然出现错误，我想知道如何以及在何处将控制器名称与Actionname交换，即使在我未点击控制器的情况下，

My Controller name is UserRegistration and the action i am redirecting is VerifyEmail, When i enter an invalid email it checks for valid email and print error msg but suddenly gives error The IControllerFactory ''Web.Mvc.SpringControllerFactory'' did not return a controller for the name ''VerifyEmail''.

and when i see URL it becomes http:\localhost:4000\VerifyEmail\UserRegistration

The same error is arising if i enter a valid email,it sends email display success msg then suddenly gives error i am wondering how and where it is swaping controller''s name with Actionname,Even in the situation when i am not hitting controller

使用keydown…键码13…真是个坏主意.首先，如果您进行了工作，它将使用户意外，导致意外发送.为什么不使用常规按钮?而且，顺便说一下，带有"post" HTTP请求的常规Web表单也不是. HTTP请求在哪里?您应该使用Ajax或Web表单.

甚至不要考虑在客户端验证数据的想法.如果不更糟的话，这很容易使您的主机变成发送垃圾邮件的僵尸.您应该确实对其进行很好的验证，并且只能在服务器端进行验证.

我在过去的回答中解释了这种危险:
无法发送邮件，它显示了以下代码中的错误. [

Using keydown… key code 13… really bad idea. First of all, if you make if working, it would be unexpected by the user, cause accidental sends. Why not using a regular button? And, by the way, not regular Web form with the "post" HTTP request. And where is you HTTP request? You are supposed to use Ajax or a Web form.

Don''t even play with the idea to validate data on the client side. It''s way to easy to turn your host into a zombie sending spam if not worse. You should really validate it well, and only on the server side.

I explain the danger in my past answer:
unable to send mail , it showing the error in below code .[^].

Please take it very seriously! This is a real danger which could be fatal to your site! I know it from real life.

Take care,
