带有多个按钮的jQuery模态表单

jQuery modal form with multiple buttons

本文关键字:jQuery 模态 表单 按钮      更新时间:2023-09-26

是否有办法在jQuery中使用多个按钮使用模态表单?

实际上所有的按钮都有相同的名称和ID。我只是希望每次我点击任何按钮,模态表单都会弹出。

让我们使用下面的jQuery示例:有3个按钮。

刚刚回答

ID在页面中应该是唯一的,当你有多个相同ID的元素时,jQuery只选择第一个。这是因为它不需要费力去寻找其他的,因为应该没有更多的了——这也许可以解释你所经历的奇怪行为。

给你的按钮不同的ID

如果您希望多个元素具有相同的功能,请为它们提供相同的类。

实际上所有按钮都有相同的名称和id?

Id s总是唯一的。使用Class代替。更多信息。

 <button class ="create-user">Create new user</button>
 <button class ="create-user">Create new user1</button>
 <button class ="create-user">Create new user2</button>
