Differences between ASP. NET page and response output JS

After the submission is successful, the alert dialog box is displayed, using page. clientscript. registerclientscriptblock and direct response. write ("<SCRIPT type = 'text/JavaScript '>" + script + "</SCRIPT> ");

The alert content is displayed. However, the style of the page is changed by using the response method. Unexpected page disorder occurs. The cause is unknown.

Below is a JS group class

   Public   Class  Jshelper {  Public   Static  Httpresponse response {  Get { Return Httpcontext. Current. response ;}}  ///   <Summary>          ///  This method will inexplicably lose the style if the page has a server text box Control  ///   </Summary>          ///   <Param name = "script"> </param>          Public   Static   Void Executescript ( String  Script) {response. Write ( "  <SCRIPT type = 'text/JavaScript '>  " + Script + "  </SCRIPT>  "  );}  ///   <Summary>          ///  This method can achieve the expected alert effect without changing the style  ///   </Summary>          ///   <Param name = "script"> </param>         ///   <Param name = "page"> </param>          Public   Static   Void Executescript ( String  Script, page) {page. clientscript. registerclientscriptblock (  Typeof (Page ), "  MSG  " , "  <SCRIPT type = 'text/JavaScript '>  " + Script + "  </SCRIPT>  " , False  );}  Public   Static   Void Gotourl ( String  URL) {response. Write (  "  <SCRIPT type = 'text/JavaScript '> top. Location. href ='  " + URL + " '; </SCRIPT>  "  );}} 

1. UsePublic Static VoidExecutescript (StringScript) method:

 
2. UsePublic Static VoidExecutescript (StringScript, page)Method:

 

The second is normal. The style of the text box is not deformed.
