如何编辑使用 jQuery 切换引导模式的按钮？

Question

我有一些按钮，可以切换相同的引导模式。

我想要实现的是，当我点击模态框内的 Edit toggler 按钮时，例如切换它的按钮的背景会变为红色。 p>

所以如果Show modal 2切换它，通过点击Edit toggler，Show modal 2的背景会变成红色。 p>

或者如果是 Show modal 3 切换了模态，那么它的背景会改变，等等

Answer 1

例如，您应该为按钮添加一个唯一标识符。 #id="edit-toggler"... 然后简单地说：

$("#edit-toggler").on('click', function(){
    $('#show-modal-2').toggleClass("red");
});

CSS：

.red{
    background-color: red
}

我会推荐这种方法，它更容易修改和维护。将 css 属性和值硬编码到 Jquery 中并不是很有用:)
