javascript - jquery msgBox execution in code behind(c#) -

I want to show a message box when the user enters the wrong "A" D or password. I type the following function in the .aspx file:

  & lt; Script type = "text / javascript" & gt; Function Warning Message () {$ .msgbox ({title: "HatalÄ ± GiriÅ ??", Content: "Kullan ± numerals ± or da A ... efre removed ± ...", type: "error", Button: [{Value: "OK"}]}); } & Lt; / Script & gt;   
 And I write the following code in the aspx.cs file:  
  ScriptManager.RegisterStartupScript (this.page, this.GetType (), "warning message "," Warning message () ", incorrect);   
 But this code does not work Can you help me?   
 
 
 It is necessary to include 3 files while using:  
  & Lt; Script src = "scripts / jquery-2.0.0.js" type = "text / javascript" & gt; & Lt; / Script & gt; & Lt; Script src = "script / jquery.msgBox.js" type = "text / javascript" & gt; & Lt; / Script & gt; & Lt; Link href = "Styles / msgBoxLight.css" rel = "stylesheet" type = "text / css" & gt;   
 I used this code on client-side:  
    
 On the server-side:  
  Page.ClientScript.RegisterStartupScript (this.GetType (), blank, "warning message ();", true) ;   
   This works best for me
