I have a select field with a list of names, after selecting one of them I have to assign a value in the database to an input field.

Esquema

php javascript html

  • jquery or vanilla even?

  • "assign a bank value to an input field" - you can explain that part better?

  • you have to assign the value that was selected in the select field to input as well ? That’s it ?

  • Yes. I have to sweep the bank (select * from bank')

  • in the input field I have to assign this value!

  • Good if it is as I think, with javascript this is solved, because as you select the value within select it fills the input field you need with that respective value

  • some example, step-by-step or case study ?

  • I created an answer to this, if you attend me a feedback marking as best response

  • Let’s go continue this discussion in chat.

  • You want to search by name or by some name code?

From what I understand you want to catch the value of your field select and play for a field input if it’s not that, comment that I edit the answer to suit better

<script type="text/javascript">
        $(document).on('change', '.get-placa', function () {
            var value = $(this).val();
            $('.close').trigger('click');
            $('.campo2').val(value);
        });
</script>

<div class="col-lg-3">
    <select class="form-control get-placa" type="text"  name="campo1" maxlength='4'>
        <option></option>
        <option value='Campo1'>Campo1</option>
        <option value='Campo2'>Campo2</option>
    </select>
</div>

<div class="col-lg-3">
    <label for="ex1">Pegando Value do Select:</label>
    <input type="text" class="form-control campo2" maxlength="14"  name="campo2"><br><!-- Input CNPJ -->
</div>

  • take the value of your select field and play for an input field, that’s right...!
