Hallo an alle!

Leider finde keine wirkliche Erklärung zu meinem Problem, denn logik schein dem ie fremd, oder mir !?!

folgender code :

  
<html>  
<head>  
</head>  
<script language="JavaScript">  
var Class = { create: function(){ return function(){ this.initialize.apply(this, arguments); } } }  
  
var CAjaxUploadForm = Class.create();  
CAjaxUploadForm.prototype.initialize=function(id,reciever,action,target){  
  this.id=id;  
  this.reciever=reciever;  
  this.target=target;  
  this.action=action;  
  this.html=function(elementtype){return document.createElement(elementtype);};  
  this.make=function(){  
   this._form = document.createElement("FORM");  
   this._form.id="form_" + id;  
   this._form.name="form_" + id;  
   this._form.method="post";  
   this._form.enctype="multipart/form-data";  
   this._form.target=this.target;  
   this._form.action=this.action;  
  
   this._file = document.createElement("INPUT");  
   this._file.type="file";  
   this._file.id=this._file.name="file_" + this.id;  
  
   this._button = document.createElement("INPUT");  
   this._button.type="button";  
   this._button.value="upload";  
   var func = this.onClick(this._form.id);  
   this._button.onclick=func;  
  
   this._form.appendChild(this._file);  
   this._form.appendChild(this._button);  
  
   x=document.getElementById(this.reciever);  
   x.appendChild(this._form);  
  }  
  this.onClick=function(former){  
   return function(){sub_form(former);}  
  }  
  
}  
  
  
var CAjaxUploader = Class.create();  
CAjaxUploader.prototype.initialize=function(in_element){  
  this.htmlelement=in_element;  
  this.Iframes=new Array();  
  this.Uploads=new Array();  
  this.draw=function(Uploads,action){  
   for(var i=0;i<Uploads;++i){  
   this.Uploads[i]=new Array();  
   this.Uploads[i][0]=this.doIframe(i,action);  
   this.Uploads[i][1]=new CAjaxUploadForm("Form_" + i, this.htmlelement, action, this.Uploads[i][0]);  
   this.Uploads[i][1].make();  
  }  
  }  
  this.doIframe=function(id,action){  
   x=document.getElementById(this.htmlelement);  
   _iframe = document.createElement("IFRAME");  
   _iframe.id="IFRAME_" + id;  
   _iframe.name="IFRAME_" + id;  
   _iframe.src=action;  
   x.appendChild(_iframe);  
   return _iframe.id;  
  }  
  
}  
  
  
  
function sub_form(form){  
 x = document.getElementById(form);  
 x.submit();  
}  
  
</script>  
<body>  
<div id="UploadArea"></div>  
  
<script language="JavaScript">  
var Upload = new CAjaxUploader("UploadArea");  
Upload.draw(4,"recieve.php");  
  
</script>  
</body>  
</html>

Wird vom Firefox einwandfrei ausgeführt, also das generierte formular wird abgesendet und im entsprechend generierten iframe verarbeitet, aber mein freund der internet explorer (v7) senden den post an target="_blank"...

hab noch eben opera gecheckt, der machts auch richtig

kann mir bitte einer ne erklärung geben warum der ie das macht bzw. wie ich den "fehler" umgehen kann ??

mfg
