有没有办法在jQuery中使用多个按钮使用模态表单?

实际上所有按钮都具有相同的名称和ID。我只是希望每次点击任何按钮时都会弹出模态表单。

让我们使用下面jQuery中的示例:有3个按钮。

实际上所有按钮都有相同的名称和ID?

Id始终是唯一的。请改用ClassMore Info

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

刚刚回答

ID在页面上应该是唯一的,当你有多个具有相同ID的元素时,jQuery只选择第一个。那是因为它不必费心寻找别人,因为不应该再这样了 - 这可能解释了你所经历的奇怪行为。

为您的按钮提供不同的ID

如果您希望多个元素具有相同的功能,请为它们指定相同的类。
