javascript - 我不断收到此错误语法错误 : JSON. 解析:JSON 数据第 1 行第 2 列出现意外字符

Question

这个让我恶心。因为我找不到哪里出错了。我会的感谢您的任何帮助或提示。下面是我的 javascript 代码。到目前为止，服务器端很好，但在客户端显示实际评论是问题所在。请帮助我。

$(document).ready(function () {
    // process the form
    $('form.comments_form').each(function () {
        var form_to_submit = $(this);
        form_to_submit.submit(function (event) {
            event.preventDefault();
            var posta_id = form_to_submit.find("input[type=hidden].UNIQUE_ID").val();
            var tetxarea1 = form_to_submit.find("textarea.target").val();

            $.ajax({
                type: 'POST', // define the type of HTTP verb we want to use (POST for our form)
                url: 'http://localhost/Forepost/php/real_time_comment.php', // the url where we want to POST
                data: {
                    posta_id: posta_id,
                    tetxarea1: tetxarea1
                }, // our data object
                dataType: 'json', // what type of data do we expect back from the server
                success: (function (response) {
                    display_the_comment(jQuery.parseJSON(response));
                    console.log(response);
                }),
                error: function () {
                    alert("oops something went wrong");
                    // oops something went wrong
                }
            });

            //FUNCTION TO DISPLAY COMMENT FROM DATABASE
            function display_the_comment(response) {
                var comment_string = " ";
                comment_string += "<li class='indiv_cmnts'>";
                comment_string += "<span class='user_fname2'>'" + response.f_name + "'</span>";
                comment_string += "<div class='my_msg'>'" + esponse.my_comment + "'</div>";
                comment_string += "<img class='user_proff' src='" + response.profile_img + "'/>";
                comment_string += "<span class='time_cmnts'>'" + response.my_comment_date + "'</span>";
                //comment_string += "<span class='fa_reply'><i class='fa fa-reply' aria-hidden='true'></i> reply</span>";
                comment_string += "</li>";

                $("ul.comenting2").prepend(comment_string);
            }
            //FUNCTION TO DISPLAY COMMENT FROM DATABASE
        });
    });
});

我正在尝试使用“commenting2”类将列表显示为无序列表

改变你的代码 $("ul.commenting2").prepend(comment_string);
到 $("ul.commenting2").prepend($(comment_string));
