Question

我想知道是否有人可以帮助我。

我对jQuery有点新意，所以请耐心等待。收到之前帖子的一些指导后，我已将模态确认对话框添加到图库页面，如下面的脚本所示。

我遇到的问题是页面加载时会打开对话框，而我只想这样做出现在单击按钮上。我已经在单击按钮时打开了对话框，但无论如何都无法在页面加载时停止打开它。

我查看了jQuery文档，但我没有看到任何可以让您选择更改此设置的内容。

我只是想知道某人是否能够看到这个并让我知道我哪里出错？

非常感谢和问候

Answer 1

从函数声明中删除$。您不需要使用jQuery来定义常规函数。

$(function showdialog() { ... });

应该是

function showdialog() { ... }

Answer 2

将类“hide”添加到css和div对话框（如下所示）：

.hide{
  display: none !important; 
 }


 <div id="dialog-confirm" class="hide" title="Delete This Image?">

jQuery Modal Confirmation Onload Open
