＆＃34;未捕获的ReferenceError：$未定义＆＃34; Bootstrap页面出错

标签： javascript bootstrap-modal

我试图将旋转木马添加到我的模态中，并且我在调用JavaScript时出现问题。我无法记住如何调用javascript文件，但我复制粘贴我在网上找到的内容。我不确定这是问题还是我找到的代码模板的问题。谢谢你的帮助。

这是我的代码：

＆＃13;
＆＃13; 
/* copy loaded thumbnails into carousel */
$('.row .thumbnail').on('load', function() {
  
}).each(function(i) {
  if(this.complete) {
  	var item = $('<div class="item"></div>');
    var itemDiv = $(this).parents('div');
    var title = $(this).parent('a').attr("title");
    
    item.attr("title",title);
  	$(itemDiv.html()).appendTo(item);
  	item.appendTo('.carousel-inner'); 
    if (i==0){ // set first item active
     item.addClass('active');
    }
  }
});

/* activate the carousel */
$('#modalCarousel').carousel({interval:false});

/* change modal title when slide changes */
$('#modalCarousel').on('slid.bs.carousel', function () {
  $('.modal-title').html($(this).find('.active').attr("title"));
})

/* when clicking a thumbnail */
$('.row .thumbnail').click(function(){
    var idx = $(this).parents('div').index();
  	var id = parseInt(idx);
  	$('#myModal').modal('show'); // show the modal
    $('#modalCarousel').carousel(id); // slide carousel to selected
  	
});
＆＃13; 
.modal-dialog {}
.thumbnail {margin-bottom:6px;}

.carousel-control.left,.carousel-control.right{
  background-image:none;
}

如果未加载或缺少jQuery脚本，则会发生此错误。

答案 1 :(得分：0)

您的代码存在的问题是您缺少引导程序轮播所需的所有外部资源

您需要添加以下提到的文件。

  <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
  <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

更新了代码段 

/* copy loaded thumbnails into carousel */
$('.row .thumbnail').on('load', function() {
  
}).each(function(i) {
  if(this.complete) {
  	var item = $('<div class="item"></div>');
    var itemDiv = $(this).parents('div');
    var title = $(this).parent('a').attr("title");
    
    item.attr("title",title);
  	$(itemDiv.html()).appendTo(item);
  	item.appendTo('.carousel-inner'); 
    if (i==0){ // set first item active
     item.addClass('active');
    }
  }
});

/* activate the carousel */
$(function(){
$('#modalCarousel').carousel({interval:false});
});

/* change modal title when slide changes */
$('#modalCarousel').on('slid.bs.carousel', function () {
  $('.modal-title').html($(this).find('.active').attr("title"));
})

/* when clicking a thumbnail */
$('.row .thumbnail').click(function(){
    var idx = $(this).parents('div').index();
  	var id = parseInt(idx);
  	$('#myModal').modal('show'); // show the modal
    $('#modalCarousel').carousel(id); // slide carousel to selected
  	
});
.modal-dialog {}
.thumbnail {margin-bottom:6px;}

.carousel-control.left,.carousel-control.right{
  background-image:none;
