Question

我已将引导菜单添加到我的网站。当我单击菜单下拉菜单时，菜单项未显示。

<nav class="collapse navbar-collapse navbar-right" role="navigation">
<div class="main-menu">
<ul class="nav navbar-nav navbar-right">
<li><a href="index.html">Home</a></li>
<li><a href="about.html">About</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" 
aria-haspopup="true" aria-expanded="false">Products
<span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="#">Sub item</a></li>
<li><a href="#">Sub item</a></li>
</ul>
</li>       
<li><a href="contact.html">Contact Us</a></li>
</ul>
</div>
</nav>

下面是使用的脚本文件。

    <script 
    src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"> 
    </script>
    <script src="js/vendor/modernizr-2.6.2.min.js"></script><!-- jquery -->` 
   `<!-- owl carouserl js -->
    <script src="js/owl.carousel.min.js"></script><!-- bootstrap js -->
    <script src="js/bootstrap.min.js"></script>
    <!-- wow js --><script src="js/wow.min.js"></script><!-- slider js -->
    <script src="js/slider.js"></script>
    <script src="js/jquery.fancybox.js"></script><!-- template main js -->
    <script src="js/main.js"></script>
    <script>
    $(document).ready(function(){
    $('.dropdown-toggle').dropdown();
    });
    </script>

Answer 1

这三个脚本都需要添加到html文件中。

studentreport<-read.csv("C:\\Users\\Joseph\\Downloads\\studentreport dataset full imp.csv",header=T,sep=",")
studentreport<-data.frame(studentreport)

smp_size <- floor(0.75 * nrow(studentreport))

set.seed(123)
train_ind <- sample(seq_len(nrow(studentreport)), size = smp_size)

train <- studentreport[train_ind, ]
test <- studentreport[-train_ind, ]

fitreport<-glm(train)
Fitstart=glm(Enrolling~1,data=train)

Report<-step(Fitstart,direction="forward",scope=formula(fitreport))

predict(Report, newdata = test,type ="response")

单击后的Bootstrap下拉菜单未显示下拉值
