我已经想出如何通过单击按钮来替换我的背景图像,但现在我想在“画廊”中放置缩略图像,您也可以点击它。我已经想出如何通过单击“下一个”和“上一个”按钮来改变图像,但每当我尝试同时点击缩略图时,它确实会让事情变得混乱。基本上,我希望能够点击一个缩略图并更改索引号,这样当你点击“下一步”按钮时,它会进入下一个图像,而在它回到第二个图像之前,无论如何您点击了什么缩略图。为简洁起见,我只包含了“下一张图片”功能。
问题在于,当我点击缩略图时,它会转到右边的图像,但是如果你点击“下一个”按钮,它就会转到第二个图像,无论你是否在第7个图像上, 5,等等。基本上,我不知道如何获取下一个图像功能来读取当前图像的索引号。
谢谢!!!

答案 0 :(得分:0)
$(function() {
var colorCurrent = 0;
var tnCurrent = 0;
// rest code
backgroundThumbs.forEach(function(value,index) {
// rest code
tnCurrent = index;
colorCurrent = tnCurrent;
// rest code
});
});
看看是否有效。
