我有 8 张缩略图，我想在单击其中一张时显示一个滑块。我几乎尝试了我所知道的一切，这里是：
HTML：
<div id="divThumbnails2" class="thumbnails2">
<a href="#" id="Thumb5" >
<img src="images/thumbnail_5.png" width="55" height="66" alt="" class="floatleft" /></a>
<a href="#" id="Thumb6">
<img src="images/thumbnail_6.png" width="56" height="67" alt="" class="floatleft"
style="margin-left: 7px;" /></a>
<a href="#" id="Thumb7">
<img src="images/thumbnail_7.png" width="54" height="66" alt="" class="floatleft"
style="margin-left: 7px;" /></a>
<a href="#" id="Thumb8">
<img src="images/thumbnail_8.png" width="57" height="68" alt="" class="floatleft"
style="margin-left: 7px;" /></a>
</div>
<div id="divThumbnails" class="thumbnails">
<div id="Thumb1" class="floatleft" >
<a href="#">
<img src="images/thumbnail_1.png" width="54" height="65" alt=""/></a>
</div>
<div id="Thumb2" class="floatleft" style="margin-left: 7px;" >
<a href="#">
<img src="images/thumbnail_2.png" width="56" height="66" alt="" /></a>
</div>
<div id="Thumb3" class="floatleft" style="margin-left: 7px;" >
<a href="#">
<img src="images/thumbnail_3.png" width="54" height="66" alt="" /></a>
</div>
<div class="floatleft" style="margin-left: 7px;" id="Thumb4">
<a href="#">
<img src="images/thumbnail_4.png" width="57" height="68" alt="" /></a>
</div>
</div>
还有幻灯片：
<div id="slides">
<div class="slides_container" id="SlidesContainer">
<a href="#"><img src="images/slides_1.png" width="408" height="266" alt="" /></a>
<a href="#"><img src="images/slides_2.png" width="408" height="272" alt="" /></a>
<a href="#"><img src="images/slides_3.png" width="408" height="275" alt="" /></a>
</div>
<a class="prev" href="#"><img width="28" height="27" alt="Arrow Prev" src="images/slides_left_arrow.png"/></a>
<a class="next" href="#"><img width="28" height="27" alt="Arrow Next" src="images/slide_arrow_right.png"/></a>
<div class="close_btn" id="Btn_Close"><a href="#"><img src="images/slide_close_btn.png" width="28" height="27" alt="Close" /></a></div>
</div>
JavaScript：
<script type="text/javascript">
var close = document.getElementById('Btn_Close');
var slides = document.getElementById('slides');
close.onclick = function () {
slides.style.display = "none";
};
</script>
<script type="text/javascript">
var thumb1 = document.getElementById('Thumb1');
var slides = document.getElementById('slides');
thumb1.onclick = function () {
slides.style.display = "block";
};
</script>
<script type="text/javascript">
var thumb2 = document.getElementById('Thumb2');
var slides = document.getElementById('slides');
thumb2.onclick = function () {
slides.style.display = "block";
};
</script>
<script type="text/javascript">
var thumb3 = document.getElementById('Thumb3');
var slides = document.getElementById('slides');
thumb3.onclick = function () {
slides.style.display = "block";
};
</script>
<script type="text/javascript">
var thumb4 = document.getElementById('Thumb4');
var slides = document.getElementById('slides');
thumb4.onclick = function () {
slides.style.display = "block";
};
</script>
<script type="text/javascript">
var thumb5 = document.getElementById('Thumb5');
var slides = document.getElementById('slides');
thumb5.onclick = function () {
slides.style.display = "block";
};
</script>
<script type="text/javascript">
var thumb6 = document.getElementById('Thumb6');
var slides = document.getElementById('slides');
thumb6.onclick = function () {
slides.style.display = "block";
};
</script>
<script type="text/javascript">
var thumb7 = document.getElementById('Thumb7');
var slides = document.getElementById('slides');
thumb7.onclick = function () {
slides.style.display = "block";
};
</script>
<script type="text/javascript">
var thumb8 = document.getElementById('Thumb8');
var slides = document.getElementById('slides');
thumb8.onclick = function () {
slides.style.display = "block";
};
</script>
当我单击箭头时，slides_container 一切都很好，它会更改我的图片，但是我必须最初将其显示属性设置为“阻止”，并且我想将其设置为“无”，因为我希望它仅在单击其中一个时出现缩略图。
当我单击它时，它与关闭按钮一起使用，slides_containerdiv 消失了（我想我做对了），但是当我单击其他按钮时，我似乎无法让它出现。任何帮助表示赞赏。
