Hello, I am new still in development and I need to validate input fields, more precisely prevent the inputs of the same column within a table have repeated values.
Html example
<!DOCTYPE html>
<html lang="pt-br">
<head>
<meta charset="utf-8" />
<title>Navegador em tabela HTML</title>
<link rel="stylesheet" type="text/css" href="estilo.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="script.js"></script>
</head>
<body>
<table class="dados">
<thead>
<tr>
<th>Código</th>
</tr>
</thead>
<tbody>
<tr>
<td><input type="text" id="idcodFab" name="cfabri"class="codFab" /></td>
</tr>
<tr>
<td><input type="text" id="idcodFab" name="cfabri"class="codFab" /></td>
</tr>
<tr>
<td><input type="text" id="idcodFab" name="cfabri"class="codFab" /></td>
</tr>
</tbody>
</table>
<input type="submit" class="Cenviar" value="Enviar" id="00007667" />
</body>
</html>From now on, I appreciate all your help.
