jQuery - Adding field fields dynamically -


im trying implement code found on website duplicates file field when click href link, code pretty same site, yet not working @ all.

could have , let me know im going wrong.

the complete code follows:

javascript:

<script> $( function(){     var jaddnewupload = $( "#add-file-upload" );      jaddnewupload         .attr( "href", "javascript:void( 0 )" )         .click(             function( objevent ){                 addnewupload();                  objevent.preventdefault();                 return( false );             }         ); } );  function addnewupload(){     var jfilescontainer = $( "mpfiles" );     var juploadtemplate = $( "#element-templates div.row" );     var jupload = juploadtemplate.clone();     var strnewhtml = jupload.html();     var intnewfilecount = (jfilescontainer.find( "div.row" ).length + 1);      jupload.attr( "id", ("file" + intnewfilecount) );      strnewhtml = strnewhtml         .replace(             new regexp( "::field3::", "i" ), ("mpfile[]")         );      jupload.html( strnewhtml );      jfilescontainer.append( jupload ); } </script>

html:

<div id="mpfiles">     <div class="row">         <label>files:</label>         <div class="files-box">             <div class="file sub-file">                 <input class="file-input-area" name="mpfile[]" type="file" size="32" value="" />                 <input readonly="readonly" class="text" type="text" value="click upload" />                 <a href="#" class="button">view</a>             </div>         </div>     </div> </div>  <div id="element-templates" style="display: none;">     <div class="row">         <label>files:</label>         <div class="files-box">             <div class="file sub-file">                 <input class="file-input-area" type="file" name="::field3::" size="32" value="" />                 <input readonly="readonly" class="text" type="text" value="click upload" />                 <a href="#" class="button">view</a>             </div>         </div>     </div> </div>  <div class="row">     <label>&nbsp;</label>     <a href="" id="add-file-upload">upload file</a> </div>

the website got code here http://www.bennadel.com/blog/1375-ask-ben-dynamically-adding-file-upload-fields-to-a-form-using-jquery.htm

function addnewupload(){ var jfilescontainer = $( "mpfiles" );

you need # before mpfiles ... this:

function addnewupload(){ var jfilescontainer = $( "#mpfiles" );
