var options = {
height: 400,
gantt: {
trackHeight: 30
}
};
var data = new google.visualization.DataTable(jsonData);
// Instantiate and draw our chart, passing in some options.
// Do not forget to check your div ID
var chart = new google.visualization.Gantt(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>

*这是getData.php的代码*
<?php
$con=mysqli_connect("localhost" , 'root' , '' , 'planification' );
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$query = "SELECT * FROM `gants` WHERE 1";
$result = mysqli_query($con,$query);
$rows = array();
while($r = mysqli_fetch_array($result)) {
$rows[] = $r;
}
echo json_encode($rows);
mysqli_close($con);
?>

在laravel中,public
文件夹只能从url
访问。所以你应该把getData.php
放在public
文件夹中。并在ajax
:
var jsonData = $.ajax({
url: "public/getData.php",
dataType: "json",
async: false
}).responseText;
