Ajax不会调用PHP文件

I have a Ajax function which should call search-engine.php but nothing happen.
Here my code:

Ajax:

 $.ajax(){
     type: 'POST',
     url: 'search-engine.php',
     data: {userInput: searchInput},
     success: function(){
     alert('works');
     },
     error: function(){
     alert('something went wrong');
     }
    }

PHP:

<?php
$userInput = $_POST("userInput");
echo $userInput;
?>

And my input is inside a form tag with method post. If is important.

    Your Javascript is all messed up. This is how it ought to look (compare and contrast with your code). And read the documentation!

     $.ajax('search-engine.php', {
          type: 'POST',
          data: { userInput:searchInput }
     }).done(function () {
          alert('works');
     }).fail(function () {
          alert('something went wrong');
     });
    

    And in the PHP you are using ( and ). You have to use the [ and ] characters. If you are not getting any errors then you should turn on errors!

    <?php
    $userInput = $_POST["userInput"];
    echo $userInput;
