You can call a tag script in your html;

<script>
    (function(){
        document.getElementById('idDoCampo').value = 'Valor Padrão';
    })();
</script>

this will work for tags input of the kind text.

Or simply:

<input type="text" id="idDoCampo" value="Valor Padrão"/>

// JS Puro
document.getElementById('codigo').value = "Teste"

// jQuery
$('#codigo').val('Teste 2');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="codigo" name="codigo" type="text" />

You can do it this way:

<input type="text" value="" id="codigo" >
<script>
document.getElementById("codigo").value = "Meu código";
</script>

It takes the element using getElementById and arrow its 'value'.
