jQuery Bootstrap无法正常运行

时间：2016-06-06 17:23:16

标签： javascript jquery html css twitter-bootstrap

对不起，如果之前已经回答过，请联系我，如果有的话，我找不到任何东西..

基本上，我的jQuery在Bootstrap上运行良好，直到我制作了一个favicon。现在我认为我的脚本/头标签对齐是关闭的，所以我试着修复过去一小时，但没有任何工作。

同样将脚本放在正文末端，就像正常一样，不起作用。不知道我在这里做错了什么。

我知道它现在在那里两次，但都不起作用。怎么了？ ：（

编辑：下拉列表不起作用，这是下拉列表的HTML：

我为按钮更改了一些CSS，这是问题吗？

正如@jdelaney所说，你错过了一个密钥ID。

<div class="collapse navbar-collapse navbar-default" id="bs-example-navbar-collapse-1">

此外，在您的代码示例中，您的js和css的路径是＆＃34; page relative＆＃34;而不是＆＃34;网站相对＆＃34;或者＆＃34;完全合格＆＃34;。因此，如果您要测试的页面不是您的＆＃34;主页＆＃34;您很可能根本不加载这些资产。您是否碰巧在控制台中看到404错误？

无论如何，这个例子似乎对@jdelaney建议的编辑起作用。

＆＃13;
＆＃13; 
.nav > li a {
    color: #e97117;
}

.nav > li a:hover, a:focus {
    color: #e97117;
}

/* Navbar link Colours */

.navbar-default a:hover, a:focus {
    color: #e97117 !important;
}

/* Button Colour */

.btn {
    color: #fff;
    font-family: 'Exo 2', sans-serif;
}

.btn-default:hover,
.btn-default:focus {

.btn-secondary {

答案 1 :(得分：1)

查看定义折叠按钮的行：

<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">

注意它是如何data-target的。这指的是要崩溃的元素。如果您查看example on the Bootstrap site，您会注意到主要导航栏内容div具有该ID（您的HTML丢失）：

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">

我要尝试的第一件事就是在头脑中：

变化

<script src="js/jquery-1.12.4.min.js"></script>

到

<script src="js/jquery-1.12.4.min.js"></script>
<script src="js/bootstrap.min.js"></script>

答案 3 :(得分：0)

我认为当你包含两次JQuery时会出现问题。我可以在您的代码中看到您在两个地方引用return B(1-a); 。删除<script src="js/jquery-1.12.4.min.js"></script>标记中的一个＆amp;再试一次。

答案 4 :(得分：0)

我尝试了你的示例html和css代码，我只更改了jquery和bootstrap的包含（从部分删除了jquery并包含了来自cdn的jquery和bootstrap），你可以看到它没有任何问题。

仔细检查你的jquery和bootstrap是否正确包含（文件路径/版本冲突？）。

答案 5 :(得分：0)

问题出在CSS中。

我添加了一个溢出：隐藏的函数，我读过它，因为我的隧道视图是jQuery。

J Delaney帮助我找到了它，现在一切都已修好了。

感谢所有试图帮助我的人！没有完整的代码你就不可能知道，但我仍然非常感谢你的帮助！
