我试图让一个弹出对话框显示在图像上传器上（这是正文中的第一个div），但我在jquery.min.js中不断收到此错误：
jQuery.Deferred异常：$（...）。对话框不是函数TypeError：$（...）。对话框不是函数
以及此错误：
未捕获的TypeError：$（...）。对话框不是函数
表单也不会作为单独的对话框弹出，而只是显示在屏幕的底部，如下面的链接所示：

我已经尝试将我的bootstrap cdn更新为4.0.0，但这会导致图像上传器div消失，表单停留在页面底部。有谁知道我应该如何解决这个问题？
答案 0 :(得分：0)
首先加载“jquery-2.2.0.min.js”然后“jquery-ui.min.js”以删除错误。
