With JQuery Create Dynamic Rows to table

JQuery:

function itemRowsCreation(){
$('#itemsCount').keyup(function(){
   if(!isNaN($('#itemsCount').val())){
    $('#itemsCount').attr("readonly",true);
    var rowCount = $("#itemsTable tbody tr").length;
    if(rowCount == 0){
    $('#itemsTable tbody').empty();
for(var i = 1; i <= $('#itemsCount').val(); i++)
$('#itemsTable tbody').append("<tr id=row-"+i+"><td>"+i+" Row</td><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td><td><a href=#  id="+i+" onclick=itemRowDeletion('"+i+"')>Delete</a></td></tr>");
}
}
   else $('#itemsCount').val('');
});
}

function itemRowDeletion(rowId){
$('#itemsTable tbody tr').each(function(){
if($(this).attr('id')=="row-"+rowId){
$(this).remove();
$('#itemsCount').val(parseInt($('#itemsCount').val())-1);
}
});
if($("#itemsTable tbody tr").length==0) $('#itemsCount').attr("readonly",false);
}
