Possibile duplicato di [File multipli selezionare e caricare] (http://stackoverflow.com/questions/8669579/multiple-files-select-and-upload) – billynoah

si dovrebbe fare ciclo

function upload() { 


    for (var i = 0; i < document.getElementById("fileinput").files.length; i++) 
     {       
       document.getElementById("uploading").innerHTML="uploading...."; 
       var myfile=document.getElementById("fileinput").files[i]; 
       //alert(myfile.size); 
       var r = new FileReader(); 
       r.onload = function(e) 
       { 
        var contents = e.target.result; 

        parseContents(contents); 
        //document.getElementById("cont").innerHTML=fileContent; 

        document.getElementById("uploading").innerHTML="<h3>File uploaded: "+myfile.name; 
       } 

       r.readAsText(myfile); 
     } 
}

provare questo vi aiuterà a

function upload() { 
     document.getElementById("uploading").innerHTML="uploading...."; 
     var myfile=document.getElementById("fileinput").files[0]; 

     //alert(myfile.size); 
     var r = new FileReader(); 

     r.onload = function(e) { 

     if(!e.target.files) return; 

     var files = e.target.files; 
     for(var i=0; i < files.length; i++) { 
      var f = files[i]; 
      document.getElementById("uploading").innerHTML="<h3>File uploaded: "+f; 
     } 
    }
