Javascript kombiniert mit Ajax, um den Inhalt von TXT-Dateien zu lesen_Javascript-Fähigkeiten

Der Code ist sehr prägnant, daher wird es hier keinen Unsinn mehr geben. Gehen Sie einfach zum Quellcode

HTML-Code

Code kopieren Der Code lautet wie folgt:

         


                                                                                                                                                                                                            .                                     
                                                                                                  Funktion show(){
Ajax('read.txt?datetime=new Date.getTime ',function(str){alert(str);},function(){alert('failed');})
            };
                                                                                     




Javascript-Code

Code kopieren Der Code lautet wie folgt:

Funktion Ajax(url,fnSucc,fnFaild)
                 {
//1. Ajax-Objekt erstellen
If(window.XMLHttpRequest)
                                   {// Code für IE7, Firefox, Chrome, Opera, Safari
                        var oAjax=new XMLHttpRequest();
                 }
Sonst                                                                                                                                                                                                                                     {// Code für IE6, IE5
                    var oAjax=new ActiveXObject("Microsoft.XMLHTTP");
                 }
//2. Link zum Server (Verbindung zum Server öffnen)
//open(Methode, Dateiname, asynchrone Übertragung)
                   oAjax.open('GET',url,true);
//3.Senden
                  oAjax.send();
//4.Receive return
                   oAjax.onreadystatechange=function()
                                                       {
If (oAjax.readyState==4)
                                                               {
If(oAjax.status==200)
                                                                                                                                                                                                                                                                                bis fnSucc(oAjax.responseText);
                                                                                                   } anders                                                                                                                                                                                                                                                                                        through fnFaild(oAjax.status);
                                                                                                   }                         };
                  };
              }
