我是wordpress的新手。。。请帮助。。。无法使用此代码。。。[datatable}短代码是一个插件短代码（因此它确实存在）

Worpress页面：

<label>Client ID Nr</label>   <input id="clientidnr" name="clientidnr" placeholder="9999" type="text">   <input type="button" style="background-color:#6D4053;color:white;" onclick="customidnr(0, \'shortc\')" name="submit" value="Submit" />

function customidnr(idnr) {
  var input;
  if (idnr !== undefined && idnr !== 0) {
    input = idnr;
    storeDataidnr(input);
    // alert("Storing idnr data1: " + input);
  } else {
    input = document.getElementById("clientidnr").value;
    storeDataidnr(input);
    // alert("Storing idnr data2: " + input);
  }

   jQuery.post(
    ajaxurl, 
    {
        \'action\': \'custom_id_nr\',
        \'idnr\': input
    }, 
    function(response){
        alert(\'The server responded: \' + response);
    }
);

}

function storeDataidnr(clientidnr) {
  alert("ML/TF Risk data will be displayed for ID Nr:  " + clientidnr);
  sessionStorage.setItem("idnr", clientidnr);
}

/** jquery fix  ********************************************************************************************** */
add_action( \'wp_enqueue_scripts\', \'load_old_jquery_fix\', 10 );

function load_old_jquery_fix() {
    if ( ! is_admin() ) {
        wp_deregister_script( \'jquery\' );
        wp_register_script( \'jquery\', ( "//ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js" ), false, \'1.11.3\' );
        wp_enqueue_script( \'jquery\' );
    }
}


/** idnr **************************************************************************************************** */
add_action( \'wp_ajax_custom_id_nr\', \'custom_id_nr\' );
add_action( \'wp_ajax_nopriv_custom_id_nr\', \'custom_id_nr\' );

function custom_id_nr() {
    $clidnr = intval( $_POST[\'idnr\'] );
    $shortcode = sprintf(
    \'[wpdatatable id=30 var1="%1$s"]\',
    $clidnr
    );
echo do_shortcode( $shortcode );
wp_die();
}
