Question

我使用jquery创建了一个照片库。

当我点击下一步时，我的图像会根据索引而变化。但我想，当我也点击拇指（小图像）图像时，将根据该索引显示大图像。但我不知道怎么能这样做。

请帮我解决这个问题。

如果可能，请清楚地给我完整的代码。

我的单页代码是：

$(function() {
  $("#thumbs").find(".thumb:first").addClass("active");
  $("#large").find(".bigthumb:first").addClass("active");

  var getIndex = $("#thumbs").find(".active").index();

  $(".controls").each(function() {
    $(this).find(".next").click(function() {
      getIndex = $("#thumbs").find(".active").index();
      getIndex += 1;
      if (getIndex > ($("#thumbs").find(".thumb").length - 1)) {
        getIndex = 0;
      }
      setActiveImage(getIndex);
    });
    $(this).find(".prev").click(function() {
      getIndex -= 1;
      if (getIndex < 0) {
        getIndex = $("#thumbs").find(".thumb").length - 1;
      }
      setActiveImage(getIndex); //Set/Show Active Image
    });
  });

});

function setActiveImage(index) {
  if (typeof(index) == "undefined" || index == "" || index == null) index = 0;

  $("#thumbs").find(".thumb").removeClass("active");
  $("#thumbs").find(".thumb:eq(" + index + ")").addClass("active");
  $("#large").find(".bigthumb").removeClass("active");
  $("#large").find(".bigthumb:eq(" + index + ")").addClass("active");
}

#thumbs {
  text-align: center;
  background: #77a5c6;
  padding: 5px;
}

.thumb {
  display: inline-block;
  margin: 0px;
  padding: 0px;
  cursor: pointer;
}

#thumbs .active {
  border: 3px solid #333;
}

.controls {
  margin-left: 10px;
}

.controls img {
  cursor: pointer;
  margin: 0px;
}

.controls span {
  font-size: 13px;
  display: inline-block;
  vertical-align: top;
  margin-top: 5px;
}

#large {
  text-align: center;
}

#large .bigthumb {
  display: none;
}

#large .active {
  display: block;
}

#large .active img {
  border: 2px solid #333;
}

Answer 1

只需点击.thumb上的点击事件，然后使用 .index() 获取索引，并将其传递给您的setActiveImage功能，如下所示：

$("#thumbs .thumb").on('click',function(){
   var index=$(this).index();
   setActiveImage(index);
})

Answer 2

或者您只需将<img src="http://images.replacements.com/images/images5/china/C/lenox_china_garden_birds_no_box_P0000014675S0122T2.jpg" width="100" height="80" onclick="setActiveImage(0) "/>事件添加到代码定义中，就像我在此fiddle中所做的那样

$loop = new WP_Query(array('post_type' => array('product', 'product_variation'), 'posts_per_page' => -1));
