我正在尝试开发一个简单的API调用,它在JSON响应中返回我的注释,但是当我点击它时,我得到了错误
$(...).getJSON is not a function
我的想法是,当我点击"评论"按钮(id = showarea)时,它立即打印出该答案和textarea的评论.
我在文件上"硬编码"只是为了测试.
我有这个文件(javascript/askme/comment.js)
function initCommentReloader() {
$('#textarea').on('click', 'a', function() {
$.getJSON("/controller/api/comments/comment.php", {answerid: answerid}, function(data) {
$.each(data, function(i, comment) {
console.log(comment);
});
});
});
}

但当没有任何事情发生时,它甚至不识别点击,然后我改为硬编码方式,错误发生了.我检查了我的jquery包含,一切似乎都包含在内.
这是我正在尝试加载评论的文件.你能找到什么问题吗?
我很抱歉,如果这是一个极端的新手,但我一直在强调这种方式.
亲切的问候

这可能不是这里的特定问题,但如果使用排除 ajax、动画等的“slim”版本的 jQuery,也会出现同样的令人困惑的错误。如果“.slim”出现在包含 jQuery 的行中,请尝试将其删除.
此外,请检查浏览器控制台以确保 jQuery 加载正确且未出现 404 或类似错误。
你可以试试:
$(document).on('click', '#textarea>a', function() {
$.getJSON(
"/controller/api/comments/comment.php",
{answerid: answerid},
function(data) {
$.each(data, function(i, comment) {
console.log(comment);
});
}
);
});
