How to solve the use of execcommand in JavaScript (_javascript technique

This solution only adapts to the ASP.net MVC development environment, and other environments are for reference only.

Problem Description: Encountered in the development of such requirements, save the page, usually using JavaScript SaveAs to save, the browser to SaveAs support, see the table below.

Code one: Initial saved code, only ie6,7,8 support.

 function Cmdsave () {
  var OW = window.open (' "," _blank "," ");
  var DD = new Date ();
  OW.document.open ();
  var content = document.getElementById ("content"). InnerHTML;
  OW.document.write (content);
  var name = Minename + "-" + $ ("#selDate"). Val () + ". htm";
  OW.document.execCommand ("SaveAs", false, name);//execute save, IE6,IE7,IE8 valid
  ow.close ();
 }

Solution: Considering the download compatibility is good, can also play the role of saving the page, so the use of the page, and then download the page such a solution.

Code two: Save the page code with the download method.

 function Cmdsave () {var css = ' <style type= ' text/css ' >.trnormaltd {border-top-width:0px; Border-bottom-width:0px;text-align:right}. TRLASTTD {border-top-width:0px;text-align:right}. Trfirsttd{border-bottom-width:0px;text-align:right;}
  </style> ";
  var html = document.getElementById ("content"). InnerHTML;
  var content = css + html;
  var name = Minename + "-" + $ ("#selDate"). Val () + ". htm";
Savepage (content, name); //content content filename FileName first generates page on server, then downloads generated page function savepage (content, FileName) {$.ajax ({type: ' Post ', D Atatype: ' text ', url: ' Fxbb/bcym ', data: {content:content, filename:filename}, Success:function (
    result) {var url = "Yxgz/dbfx/bbcx/fxbb/xzym?filename=" + fileName;
    var downloadurl = Window.location.protocol + "//" + Window.location.host + "/" + URL;
   window.open (DownloadURL);//download page//deletefile (fileName);
   Error:function (msg) {alert ("Save Error");
 }
  }); //Save page public int BCYM (string content, String fileName) {string path = System.AppDomain.CurrentDomain.BaseDirectory;
   Path = Path.Combine (path, @ "UPLOAD\FXBB"); Empty Save file Folder file foreach (String d in directory.getfilesystementries (path)) {if (file.exists (d)) {FILE.D
    Elete (d);
   }//Generate the page to be saved path = System.AppDomain.CurrentDomain.BaseDirectory;
   Path = Path.Combine (path, "upload/fxbb/" + fileName); using (StreamWriter sw = new StreamWriter (path, False, Encoding.UTF8))//File.appendtext (path)) {SW.
    WriteLine (content); Sw.
   Flush ();
  return 1;
   ///download page public void Xzym (string fileName) {string path = System.AppDomain.CurrentDomain.BaseDirectory;
   Path = Path.Combine (path, @ "upload\fxbb\" + fileName); String filePath = Path;//server.mappath ("Download/aaa.zip");//path//download file in the form of a character stream FileStream fs = new FileStream (Filepa
   th, FileMode.Open); byte[] bytes = new byte[(int) fs.
   Length]; Fs. Read (bytes, 0, bytes.
   Length); Fs. Close ();
   System.Web.HttpContext.Current.Response.ContentType = "Application/octet-stream"; Notifies the browser to download the file instead of opening System.Web.HttpContext.Current.Response.AddHeader ("Content-disposition", "attachment;
   Filename= "+ httputility.urlencode (FileName, System.Text.Encoding.UTF8));
  System.Web.HttpContext.Current.Response.WriteFile (FilePath); }
