php - 为什么ajax等待超过一秒？

Question

我遇到了一个问题。当我发出 ajax 请求时，它运行良好，但状态等待了 1 秒多一点。这对我来说似乎真的很高。

这是 Chrome 中网络选项卡的屏幕截图

这是我正在使用的ajax函数。

function subCommentSubmit() {
        $('.subComment').on('submit', function() {

            var url = "/laravel/public/utility/submitsubcomment"; // the script where you handle the form input.
            // Submits the data with ajax, method type is POST
            var currentElement = $(this);
            var thatPar = currentElement.parent().parent();
            var liveSubCommSection = $('> .live-sub-comments', thatPar);
            var commentLoader = $('> .loader-comments > .loader', thatPar);

            var formData = currentElement.serialize();
            $('.new-reply', currentElement).val('').blur().trigger('autosize.resize');

            commentLoader.removeClass('hide').fadeIn(250, function() {
                $.ajax({
                       type: "POST",
                       url: url,
                       data: formData, // serializes the form's elements.
                       success: function(data)
                       {    
                            commentLoader.fadeOut(250, function() {
                                commentLoader.addClass('hide');
                                var response = JSON.parse(data);   
                                var commentPost = $('<li class="single-user-reply"> <div class="user-ava-cont"> <a href="'+ response.userid +'" class="user-ava-a"><img src="../images/avatest1.png"> </a> </div><div class="s-w-user-details"><a href="'+ response.userid +'" class="s-w-poster upop">'+ response.username +' </a> <span class="s-w-timestamp">1 second ago</span><a href="#" class="likes-but notliked active">Like</a> <a href="#" class="likes-but liked">Liked</a><ul class="more-dropdown-cont" role="button"> <li class="dropdown minidrop"><button class="more-dropdown dropdown-toggle" role="button" data-toggle="dropdown"><i class="icon down"></i></button><ul class="dropdown-menu" role="menu" aria-labelledby="people"><li role="presentation"><a class="u-a-a" role="menuitem" tabindex="-1" href="#">Block User</a></li><li role="presentation"><a class="u-a-a" role="menuitem" tabindex="-1" href="#">Report Abuse</a></li></ul></li></ul><div class="s-w-user-post">'+ response.comment +'</div><div class="clear"></div></div></li>');
                                commentPost.hide();
                                liveSubCommSection.append(commentPost.fadeIn(250)); 
                                subCommentSubmit();
                            });
                       }
                }); 
            });
            currentElement.unbind('submit');
            // Ensures it doesn't route the form the normal way, and ajax takes over
            return false;

        });
    }

我会分析您的 PHP 文件，因为这似乎是您问题的根源。

我不熟悉 Laravel 的分析选项，但您可以做的简单事情是:

class utility{

    function submitsubcomment(){
        $start = microtime(true);

        //Your code is here

        echo (microtime(true) - $start);
    }

}

祝你好运!
