Der Artikel beginnt mit einem einfachen Tutorial zum Erstellen von JQuery zum Implementieren eines einfachen Datei-Upload-Formularstils.

Javascript-Teilecode:
<script>$(function(){
$("input[type=file]").change(function(){$(this).parents(".uploader").find(".filename").val($(this).val());});
$("input[type=file]").each(function(){
if($(this).val()==""){$(this).parents(".uploader").find(".filename").val("No file selected...");}
});
});
</script>
