WordPress - Ajax成功函数给出空响应

Question

I have this script:

        <script type="text/javascript">
            jQuery(document).on("click",".pending-post-approve-link",function(e){

                jQuery('#review_post_status').val('approve');

                var globalVar = jQuery(this).find('.review_post_id').val();
                jQuery('#review_post_current_id').val(globalVar);

                jQuery('#post-preloader-'+globalVar).fadeIn(500);

                $.fn.wpjobusSubmitFormFunction();

            });

            $.fn.wpjobusSubmitFormFunction = function() {

                var globalVar = jQuery('#review_post_current_id').val();

                jQuery('#wpjobus-pending-posts').ajaxSubmit
                ({
                    url: '<?php echo admin_url('admin-ajax.php'); ?>',   
                    data: jQuery('#wpjobus-pending-posts').serialize(),
                    type: "POST",
                    success: function(response)
                    {
                        jQuery('#post-preloader-'+response).fadeOut(100);
                        jQuery('#post-'+response).fadeOut(100, function()
                        {
                            jQuery(this).css('display', 'none');
                        });
                        return false;
                    }
                });
            }

        });

        </script>

When this script runs, it gives me empty response. I don't know what causing this problem. This is happening in the success function of the ajax success: function(response). Any help would be appreciated.

You might have done some of those steps, but myself I would take this approach to find the issues:

• Use a tool such as Google Chrome console or Firebug for FF to check if your request is being sent to the expected url, and that it is getting an expected response.
• If it is not getting the expected response, the issue is serverside and you should look there. You can also make some breakpoint using the same tools (console/firebug) to see if the parameters which you are passing look as expected (you can check the POST header details instead too).
• Finally you can try placing a breakpoint on the success function to be sure that it gets executed at all and that the response is an empty string, and not something else.

I hope this helps.
