Print response $ .post
I have a simple web page with some parameter tags:
<!DOCTYPE HTML>
<html>
<head>
<title>Test</title>
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js" type="text/javascript"></script>
</head>
<body>
<form>
<label>Seleziona l'ente</label>
<select name="data" id="data">
<option value="PRO - 011142764">COMUNE DI AGLIE'</option>
<option value="PRO - 011120674">COMUNE DI AGRATE CONTURBIA</option>
</select>
<input type="text" name="textfield" id="textfield" />
</form>
<script>
$('#data').change(function() {
$.post("richiesta.php", { value: this.value });
$('#textfield').val(this.value);
});
</script>
</body>
</html>
Here richiesta.php
(called from within a function $.post
):
<?php
function soldipubblici() {
list($comparto, $ente) = explode("-", $_POST['value'], 2);
$curl_parameters = array(
'codicecomparto' => trim($comparto),
'codiceente' => trim($ente),
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://soldipubblici.gov.it/it/ricerca");
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query( $curl_parameters ));
curl_setopt($ch,CURLOPT_HTTPHEADER,array (
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8",
"Accept: application/json",
"X-Requested-With: XMLHttpRequest",
));
$output=curl_exec($ch);
curl_close($ch);
}
echo soldipubblici();
?>
Everything works perfectly. In Firebug I can see that a request made from richiesta.php using data collected from POST is returning correctly.
I just can't figure out how to print the response I see in Firebug on the screen (or in the input tag). I tried something like:
$('#data').change(function() {
$.ajax({
url: 'richiesta.php',
type: 'POST',
dataType: 'json',
data: {value: this.value},
}).done(function ( data ) {
$('#textfield').val(data);
});
});
The request still works, but in #textfield
what I am receiving [object Object]
, not JSON.

As you pointed out that the returned data is json (using dataType: 'json'
), jQuery has already parsed it so that it is no longer a string, it is an object.
If you want to see it as a json string in #textfield
, you'll have to convert it to string again:
$('#textfield').val(JSON.stringify(data));

Just use JSON.stringify . More information ...
$('#data').change(function() {
$.ajax({
url: 'richiesta.php',
type: 'POST',
dataType: 'json',
data: {value: this.value},
}).done(function ( data ) {
var simpleData = JSON.stringify(data);
$('#textfield').val(simpleData );
});
});
