I wrote a script using jQuery and AJAX today, and I get some errors...
The script:
function changeAdmin(id) {
$(document).ready(function() {
$('#ta-modarea-'+id).fadeOut('fast');
$('#ta-m-loading-'+id).fadeIn('fast');
$.ajax({
type: 'POST',
url: 'ajax_utf.php?a=changeteamadmin',
dataType: 'json',
data: {
admin : $('#admin-id-'+id).val()
},
success: function(data) {
$('#ta-m-loading-'+id).fadeOut('fast');
$('#ta-modarea-'+id).text(data.msg).fadeIn('fast');
},
error: function(jqXHR, textStatus, errorThrown) {
$('#ta-m-loading-'+id).fadeOut('fast');
$('#ta-modarea-'+id).text('HTTP Error: '+errorThrown+' | Error Message: '+textStatus).fadeIn('fast');
}
});
return false;
});
}
After the run, I get this error message: HTTP Error: SyntaxError: Unexpected token < | Error Message: parsererror
Could you help me, what should I do?
You need to send an application/json
header via PHP , like this:
header('Content-type: application/json');
That's because jQuery sends an Accept header (application/json, text/javascript
), and this is the cause of parseerror
triggered by jqXHR
.
