在ajax请求中需要一个操作来调用php函数

url : ajax_info.ajax_url,
type : \'post\',
data : form_data,
action: email_output_verification,

对该函数的调用是对die（）PHP函数的补充。区别在于，对于典型的web请求，HTML将显示给用户

摘自here

您是否尝试使用die() 而不是wp_die() 或exit()?

当AJAX调用中的PHP文件名无效时，就会出现此问题。

例如：

$.post
(       
  \'ajax.phpp\',
  variables,
  [...]

$.post
(       
  \'ajax.php\',
  variables,
  [...]

代码中的一些问题，如fire ajax挂钩&；短代码中的窗体操作

更改代码（&C）；测验

代码如下所示

功能。php

 function enqueue_scripts() {
        // Enqueue CSS
        //wp_enqueue_style(\'wp-news-search\', plugins_url(\'/css/wp-news-search.css\', __FILE__));
        // Enqueue and localize JS
        wp_enqueue_script(\'ajax-script\', get_template_directory_uri().\'/js/wp-news-search_query.js\', array(\'jquery\'), null, true);

        }
        // Other university specific logic here
    }
    setcookie(\'rguroo_form_action\',$desired_action, 14 * DAY_IN_SECONDS);
    setcookie(\'rguroo_form_email\', $sanitized_email, 14 * DAY_IN_SECONDS);
    echo "success";
    wp_die();
}

add_shortcode(\'wp_news_search\',\'wp_news_search_form\');
 function wp_news_search_form() {
    return \'<form id="email-verification">

        </form>\';
    }

  jQuery(document).ready(function () {
  jQuery(\'#email-verification\').submit(function (event) {
     event.preventDefault();
    var form_data = jQuery(this).serialize();
    jQuery.ajax({
          url : ajax_info.ajax_url,
          type : \'post\',
          data: {
              action: \'email_verification_form\',
              data: form_data,
              security: ajax_info.security
            },
          success : function( response ) {
              console.log(response);
              if(response !== \'success\') {
                jQuery(\'p.error\').html(response);
              } else {
                location.reload();
              }
          },
          fail : function( err ) {
              jQuery(\'.error\').innerHTML = "Cannot contact server";
          }
      });
    return false;
  });
});

这可能有用。从响应中按类名找到您的div，并获取它的innerhtml。

success : function( response ) {
              var error = $(response).find(\'.error-div\')[0].innerHTML;
              if(response !== \'success\') {
                jQuery(\'.error\').innerHTML = error;
              }
