jQuery Ajax没有发布到PHP文件

Question

I am new to AJAX so I know there could be a silly mistake in my code but anyways I will go ahead.

I have a function created that is called when a button is clicked. The function calls .ajax() method of jquery. I send the data to a file named 'delete_post.php`.

HTML:

<button class="btn btn-primary" onclick="deletePost(<?php echo $_GET["id"]; ?>);">Yes</button>

The above code works.

JS:

function deletePost(postid) {
    $.ajax({
        type: 'post',
        url: "delete_post.php?id="+postid,
        success: function(data) {
            if(data.error == true) console.log('error');
                    else console.log('problem?');
        }
    });
}

The above code is calling the .ajax() function but is not logging 'problem?' into the console.

Here's the PHP file:

<?php
require_once '...';
if(isset($_GET["id"])) {
    $id = $_GET["id"];
    echo "YEAH!";
} else {
    header("location: index.php");
}
?>

What's the issue and how can I fix it?

as we discussed in the chat side, you can use it like this:

JS:

function deletePost(postid) { 
$.post('delete_post.php', {id : postid}, function(data){ 
console.log(data); 
}, 'json'); 
}

PHP:

 <?php 

    require_once '...'; 
    if(isset($_POST["id"])) { 
    $data['res'] = 'yes'; 
    echo json_encode($data); 
    } else { 
    header("location: index.php"); 
    } 
    ?>
