Get JSON array

in Using jQuery • 10 years ago

Hello,

I'm a newbie on web programming and I'm trying to learn "by-my-self" so I thank you for your patience...
I have some pages in PHP and I found that is possible to get data from a database and put it on a page without refreshing the page.
I found some information on the net but none of them answer my question (I know it's a dummy question!!).
So...

I have 2 pages (page1.php and data.php).

The data.php has this code:

<?php require_once('Connections/connect.php');

$ID=7;

mysql_select_db($database_connect, $connect);
$query_rs_proposta = sprintf("SELECT * FROM f_propostasequipamentos WHERE id_equipamento = 7");
$rs_proposta = mysql_query($query_rs_proposta, $connect);// or die(mysql_error());

$row_rs_proposta = mysql_fetch_assoc($rs_proposta);
$totalRows_rs_proposta = mysql_num_rows($rs_proposta);

echo json_encode($row_rs_proposta);
?>

The page1.php has the code

...(some php)

<script type="text/javascript" src="jquery.js"> </script>

<script type="text/javascript">
    function get() {
        $.post ('data.php', { name: 7 },
                function (output) {
                    $('#descricao_completa').val(output).show();

                });
    }
</script>

...(some php)

I have a simple table with data (in page1.php), what I want to do is to select one row in that table and it will fill all the textboxes in one form to edit their content.
With the upper code I get, in the #descricao_completa textbox, the whole data parsed in the Json:

{"id_equipamento":"7","id_proposta":"4","ref_fornecedor":"CLM253-ID0305","descricao_curta":"CLM253-ID0305","descricao_completa":"Liquisys M CLM253\r\n\r\nTransmissor"}

How can I access each value of this data?
Let's say I want to put the value of descricao_completa in the #descricao_completa textbox, and the vaue of ref_fornecedor in the #ref_fornecedor textbox, etc?

Thanks in advance.

Any tips about where can I start programmimg with Javascrit is welcome (I site for dummies, please
