MVC中的幾個問題匯總

1.The model backing the 'XXXXDBContext' context has changed since the database was created. Either manually delete/update the database, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the DropCreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data.   出現上述錯誤需要在Global.asax中的Application_Start方法中加入：

Database.SetInitializer<Models.XXXXDBContext>(null);

2.<a>標籤在display：block設定下不能置中的問題。

把display:block改為display:inline-block就OK了。

3.如果用<a>標籤代替submit按鈕。

 <a href="javascript:;" onclick="javascript:document.forms[0].submit();">儲存</a>
