【中文标题】jquery.min.js：\'jQuery.Deferred 异常：$(...).dialog 不是函数\'错误【英文标题】：jquery.min.js: 'jQuery.Deferred exception: $(...).dialog is not a function' errorjquery.min.js：'jQuery.Deferred 异常：$(...).dialog 不是函数'错误 【发布时间】：2018-01-01 22:09:12 【问题描述】：我试图让一个弹出对话框出现在图像上传器上（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：$(...).dialog 不是函数 TypeError: $(...).dialog 不是函数
还有这个错误：
未捕获的类型错误：$(...).dialog 不是函数
该表单也不会作为单独的对话框弹出，而只是显示在屏幕底部，如下链接所示：

我尝试将我的引导 cdn 更新到 4.0.0，但这会导致图像上传器 div 消失并且表单停留在页面底部。有谁知道我应该如何解决这个问题？
【问题讨论】：
您包含多个版本的 jQuery。您只需要使用一个 【参考方案1】：首先加载“jquery-2.2.0.min.js”，然后加载“jquery-ui.min.js”以消除错误。
