Ajax没有返回结果

Alright so I have this code which basically finds the user inside the table users and displays it in alert, but it seems that I am doing something wrong. The log shows "Function is not set" and the alert itself displays that.

This is the HTML form I have for it

<center><form method='POST' >
    <input id="search_fix" type="text" name="search" placeholder="Search..">
    <input type="submit" name="submit_menu_search" style="display: none;">
</form></center>

This is the ajax processing

$(document).ready(function() {

    $("#search_fix").keyup(function() {
        var search_text = $(this).val();

        if(search_text != '') {
            $.ajax({  
                url:"handler.php",  
                method:"POST",  
                data:{"function":"search_ajax", search:search_text},  
                dataType:"text",  
                success:function(data){  
                    $('#search_result').html(data);
                    console.log(data);
                    alert(data);
                }  
            });  
        }
        else {

        }
    });

});

And these are my PHP functions that I used to basically search for the term

public function search_ajax($term) {
    $handler = new sql();
    $sql = $handler->connect();
    $sql->real_escape_string($term);

    $result = $sql->query("SELECT ime FROM users WHERE ime LIKE '%".$term."%'") or die (mysql_error());
    if($result->num_rows >= 1){ 
        while($row = $result->fetch_assoc()) {
            echo $row['ime'];
        }
    }

}
if(isset($_POST['function'])) {
    switch($_POST['function']) {
    case "search_ajax": {
        require_once "assembly/user.php";
        $user = new User();
        $user->search_ajax($_POST['search']);
        break;
    }


    default: {
        echo "Unknown AJAX function handler";
        break;
    }
    }
}
else {
    echo "Function is not set";
}

    It sounds like you're using a version of jQuery before 1.9.0. The method: option didn't exist in the older versions, it was called type:. That's why you're seeing the parameters appended to the URL, because type: "GET" is the default.

    So change

    method: "POST",
    

    to:

    type: "POST",
