伙计们,我不断收到这个未捕获的语法错误:意外 token <,它指向 jquery 库文件,我正在使用 JQuery(comment-insert.js) 向 AJAX(comment-insert-ajax.php) 发出请求,我尝试在 AJAX 脚本中删除 php(?>) 的结束标记,但我仍然收到错误。我实际上在添加“require_once”行时收到错误,对此感到抱歉。
评论插入ajax.php
<?php
if(isset($_POST['task']) && $_POST['task'] == 'comment-insert')
{
$userId = (int)$_POST['userId'];
$comment = addslashes(str_replace("\n","<br>",$_POST['comment']));
$std = new stdClass();
$std->comment_id = 24;
$std->userId = $userId;
$std->comment = $comment;
$std->userName = "Thabo Ambrose";
$std->profile_img= "images/tbo.jpg";
require_once $_SERVER['DOCUMENT_ROOT'] . 'defines.php';
require_once MODELS_DIR . 'Comments.php';
echo json_encode($std);
}
else
{
header('location: /');
}
以下是使用“$.post”方法发出请求的 Jquery 文件。 评论插入.js
$(document).ready(function(){
$('#comment-post-btn').click(function(){
comment_post_btn_click();
});
});
function comment_post_btn_click()
{
var _comment = $('#comment-post-text').val();
var _userId = $('#user-id').val();
var _userName = $('#user-name').val();
if(_comment.length > 0 && _userId != null)
{
//proceed with ajax call back
$.post("ajax/comment-insert-ajax.php",
{
task : "comment-insert",
userId : _userId,
comment : _comment
}
).error(
function()
{
console.log("Error : ");
}
).success(
function(data)
{
comment_insert(jQuery.parseJSON(data));
console.log("Response text : "+ data);
}
);
console.log(_comment + " "+_userName + " id of "+_userId);
}
else
{
//do something
$('#comment-post-text').addClass('alert alert-danger');
$('#comment-post-text').focus(function(){$('#comment-post-text').removeClass('alert alert-danger');});
}
//remove text in the text area after posting
$('#comment-post-text').val("");
}
function comment_insert(data)
{
var t = '';
t += '<li class="comment-holder" id="_'+data.comment_id+'">';
t += '<div class="user-img">';
t += '<img src="'+data.profile_img+'" class="user-img-pic">';
t += '</div>';
t += '<div class="comment-body">';
t += '<h3 class="username-field">'+data.userName+'</h3>';
t += '<div class="comment-text">'+data.comment+'</div>';
t += '</div>';
t += '<div class="comment-buttons-holder">';
t += '<ul>';
t += '<li class="delete-btn">x</li>';
t += '</ul>';
t += '</div>';
t += '</li>';
$('.comments-holder-ul').prepend(t);
}
错误指向jQuery库的第7497行,它指向下面的代码
jQuery.parseJSON = function(data)
{
return data;
}
最佳答案
尝试使用 JSON.parse 函数:
//proceed with ajax call back
$.post("ajax/comment-insert-ajax.php",
{
task : "comment-insert",
userId : _userId,
comment : _comment
}
).error(
function()
{
console.log("Error : ");
}
).success(
function(data)
{
comment_insert(JSON.parse(data));
console.log("Response text : "+ data);
}
);
console.log(_comment + " "+_userName + " id of "+_userId);
}
