重定向使用asp.net MVC應用程序的href屬性不工作

Question

我用導航這樣的：

<a href="/MyMessages/?messageId=1"> First message </> 

但用戶導航之前，我處理JavaScript中的事件：

$('a').on('click', function (event) { 
    event.preventDefault(); 
    // Do stuff 
    // Navigate: 
    location.pathname = $(this).attr('href'); // href is /MyMessages/?messageId=1 
}); 

但獲取瀏覽器編碼，地址是：

localhost:52500/MyMessages/%3FmessageId=1 

和MVC路由失敗：

Server Error in '/' Application.

A potentially dangerous Request.Path value was detected from the client (?).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: A potentially dangerous Request.Path value was detected from the client (?).

Source Error:

Stack Trace:

但當我只是deeplinking像

localhost:52500/MyMessages/?messageId=1 

一切正常瀏覽。

如何避免我的瀏覽器編碼我的網址，並防止我得到的錯誤？

Answer 1

，如果你在你的事件處理程序做的最後一件事就是去準確的HREF，然後取出： -

location.pathname = $(this).attr('href'); 

，並確保你不preventDefault或return false;。

正常情況下，點擊事件後瀏覽器將使用href關閉anchor重定向。

User can also choose to stay on the page (popup has yes/no buttons, after preventing default if its dirty), and then if he chooses to navigate again, the same would happen

嘗試類似： -

$('a').on('click', function (event) { 
    if(dirty){ 
     event.preventDefault(); 
     $('#yes').attr('href', $(this).attr('href')); 
     $('#popup').show(); 
    } 
}); 

，並創建#yes爲錨。
