Google Visualization API php ajax
I am using this Achieving Google Visualization chart reloads using ajax example to dynamically retrieve data from Mysql database and I get "Uncaught SyntaxError: Unexpected token <" error. This is my HTML file

google.load('visualization', '1', {packages: ['table']});

<script type="text/javascript">

function makeAjaxCall() {
$.ajax({url:'test.php',
data: {},

var arrayForGviz = eval("(" + responseData + ")");
drawVisualization(responseData);

});
}
</script>
</head>
<body>
<input type="button" onclick="makeAjaxCall();return false;" value="Click to get data"></input>
<div id="table"></div>
</body>
</html>
and This is my PHP file test.php
$con = mysql_connect("localhost","userName","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("DB_NAME", $con);
$result = mysql_query("call cargosys.rpt_salesByDate('2013/03/05','2013/03/10')");
$output = array();
while($row = mysql_fetch_array($result)) {
// create a temp array to hold the data
$temp = array();
// add the data
$temp[] = $row['inv_no'];
$temp[] = ''' . $row['bl_no'] . ''';
$temp[] = ''' . $row['inv_date'] . ''';
$temp[] = ''' . $row['cust_name'] . ''';
$temp[] = $row['Amount'];
// implode the temp array into a comma-separated list and add to the output array
$output[] = '[' . implode(', ', $temp) . ']';
}
// implode the output into a comma-newline separated list and echo
echo implode(",n", $output);
//echo json_encode($output);
mysql_close($con);
Inside the success function do:
console.log(responseData);
Then copy and paste responseData into the JSON validator at jsonlint.com
I am guessing it's a JSON syntax error, which the validator will point out to you.
