Ajax在表单提交时没有返回任何内容

Question

I am working in wordpress and on pressing the submit button I want the function to return result through ajax and result should be shown as an alert on the screen. But when I press submit nothing shows.

Below is my code

Ajax code (ajaxinsert.js file)

jQuery(document).ready(function(){

////////////////////////////////////////////////////////////
    jQuery("#addimage").submit(function (e) { //form is intercepted
        e.preventDefault();
        //serialize the form which contains secretcode
        var sentdataa = $(this).serializeArray();

        //Add the additional param to the data        
        sentdataa.push({
            name: 'action',
            value: 'wp_up'
        })

        //set sentdata as the data to be sent
        jQuery.post(yess.ajaxurl, sentdataa, function (rez) { //start of funciton
            alert(rez);

            return false;
        } //end of function
        ,
        'html'); //set the dataType as json, so you will get the parsed data in the callback
    }); // submit end here
});

HTML Form

<form id="addimage" action="" method="post" enctype="multipart/form-data">
<input type="submit" name="upload" style="margin-bottom:15px;">
</form>

PHP code (I have used shortcode on the page for this code and below code is in functions.php file) add_shortcode( 'test', 'addimage' );

function wp_up()
{   
echo "zeeshanaslamdurrani";
exit();

}

function addimage(){  

add_action( 'wp_ajax_wp_up', 'wp_up' );
add_action( 'wp_ajax_nopriv_wp_up', 'wp_up');


// register & enqueue a javascript file called globals.js
wp_register_script( 'globalss', get_stylesheet_directory_uri() . "/js/ajaxinsert.js", array( 'jquery' ) ); 
wp_enqueue_script( 'globalss' );

// use wp_localize_script to pass PHP variables into javascript
wp_localize_script( 'globalss', 'yess', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
}

Give it a try after putting the below mentioned hooks outside the add_image()function :

add_action( 'wp_ajax_wp_up', 'wp_up' );
add_action( 'wp_ajax_nopriv_wp_up', 'wp_up');
