我正在执行简单的wordpress select查询，希望使用ajax jquery执行此操作，并且不希望在按下搜索按钮并在搜索文本框中写入文本时页面刷新。我一按搜索按钮就得到零。。请在这方面提供帮助，因为如果我使用普通查询，它会使用表单提交给出结果，无论我做什么，它都会给出零。谢谢

jQuery(document).ready(function() {      
    jQuery("#Submityourskill").click(function(e){ 
        event.preventDefault();      
        jQuery.post(yes.ajaxurl,{action : \'doit\'},
            function( response) {//start of funciton
                // alert(response);
                //jQuery("#searchtextbox").val(response);
                jQuery("#result").append(response);
                jQuery("#textarea").html(response);
                return false;
            } //end of function
        );
    }); // click button function finishing here
}); //end of main loop 

<form action="" method="post">
    <div><input maxlength="200" name="secretcode" size="200" type="text" value="" placeholder="Type Here !" />
    <input id="Submityourskill" name="Submit" type="submit" value="Search Record" /></div>
</form>
<div id="result"></div>

PHP:

function doit() {
    if(isset($_POST[\'secretcode\'])!= \'\'){
        if($_POST[\'Submit\']) {
            $secretcode=$_POST[\'secretcode\'];
            global $wpdb;
            $sql = "SELECT * FROM wp_store_locator WHERE sl_description=\'$secretcode\'";
            $results = $wpdb->get_results($sql) or die(mysql_error());
            foreach( $results as $result ) {
                echo $result->sl_description;
            }
            exit();
        }
    }
}
add_action( \'wp_ajax_nopriv_doit\', \'doit\');
add_action( \'wp_ajax_doit\', \'doit\' );

function add_myjavascript(){  
    wp_register_script( \'globals\', get_stylesheet_directory_uri() . "/js/ajax-implementationn.js", array( \'jquery\' ) ); 
    wp_enqueue_script( \'globals\' );
    // use wp_localize_script to pass PHP variables into javascript
    wp_localize_script( \'globals\', \'yes\', array( \'ajaxurl\' => admin_url( \'admin-ajax.php\' ) ) );
}  
add_action( \'init\', \'add_myjavascript\' );
