模式对话框未打开聊天框的JQuery

Question

我正在尝试创建一个聊天框。一切正常，但是当我单击“开始聊天”按钮时，alert显示“对象对象”。否则，数据获取是完美的。我只是看不到模态聊天框。

[还有另一个几乎相似的示例，但是在该问题中，通过放置<div id="user_model_details"></div>得以解决，而在本示例中似乎并非如此。

最后发现了这个错误。严重的愚蠢错误。我关闭了页面末尾的</div>，而不是像这样在同一行中将其关闭：

<div class="split Connect_Content" id="Connect_Cnt"></div>

</div>位于页面末尾需要删除。它解决了问题。抱歉打扰你们。
