twitter-bootstrap 如何我的切换按钮更改颜色只有我的折叠在我的引导程序 3 导航栏中打开

How to my toggle button change color only my collapse is opened in my bootstrap 3 navbar

提问by user3216077

When we open collapse, button change color. but when we closed collapse by button click, the button doesn't return to its initial color. Button is focused. And I want that lost the focus.

当我们打开折叠时，按钮会改变颜色。但是当我们通过单击按钮关闭折叠时，按钮不会恢复到其初始颜色。按钮被聚焦。我希望这失去了焦点。

I have tried with css :focus, but it didn′t lose focus after collapse have been closed by button. I think that jquery function is necessary, although I've tried, my js skills shouldn't be sufficient.

我已经尝试过使用 css :focus，但是在按钮关闭折叠后它并没有失去焦点。我认为jquery功能是必须的，虽然我试过了，但我的js技能应该不够。

Hi the problem here is with the focusstate of the button once you click it never loses the focus unless you click outside again. You can try this:

嗨，这里的问题是focus按钮的状态，一旦你点击它就永远不会失去焦点，除非你再次点击外面。你可以试试这个：

First make a class that replicates the hoverand focusstate for the button:

首先创建一个复制按钮hover和focus状态的类：

.highlight {background:#ddd}

Then you can modify your Jquery to force the button lose his focus state on clickand apply the class to keep the visual effect:

然后您可以修改您的 Jquery 以强制按钮失去焦点状态click并应用该类以保持视觉效果：

$('.navbar-toggle').click(function() {
      $(this).toggleClass('highlight').blur();
});

Also since your collapse close every time you click outside the button you need to add some there:

此外，由于每次单击按钮外部时都会关闭折叠，因此您需要在那里添加一些：

if (_opened === true && !clickover.hasClass("navbar-toggle")) {
     $('.navbar-toggle').toggleClass('highlight'); /**Add This**/
     CloseNav();
}
