问JQuery和Bootstrap:如何将图像列表中的图像添加到旋转木马中？

EN

// As the document loads, keep a variable to define that you have not clicked a image.
var image_clicked = false;
$(document).on("click",".img-thumbnail",function(e){
  // Once you click a image on the side.
  var $this = $(e.target)
  // Check the variable
  if(!image_clicked){
    // If not clicked, clear the carousel
    $(".carousel-inner").html("");
    // mark it as clicked, so that the second time you click a image, it wont come to this block.
    image_clicked = true;
  }
    // It will append the new image to the carousel.
    // On the second time you click a image, you will only be appending elements to the carousel.
    // Add item div to the carousel.
    $(".carousel-inner").append("<div class='item'><div class='carousel-caption'><h1></h1></div></div>");
    // Get the added items
    var item = $(".carousel-inner").find(".item");
    // Get the current item and prepend a image to it.
    $(item[item.length-1]).prepend($this);
    // Remove the previous active class that was assigned
    $(".carousel-inner item").each(function(i,it){
      if($(it).hasClass("active")){
        $(it).removeClass("active");
      }
    });
    // Add a active class to the current added item
    $(item[item.length-1]).addClass("active");
    // If you images on the side have a value attribute to them
    // then keep it as caption
    $(item[item.length-1]).find(".carousel-caption h1").html($this.attr("value"));
});
