</body>尝试使用变量跟踪当前图像：
var img = 1;
然后在onClick函数中，您可以递增或递减该变量并将边框类名称添加到该图像中。
CSS： jsfiddle
img {
border: 1px solid black;
cursor: pointer;
height: 100px;
width: 100px;
}
.myBorder {
border: 1px solid red;
}
HTML： jsfiddle
<img id="1" class="myBorder"/>
<img id="2"/>
<img id="3"/>
<img id="4"/>
<button class="prevButton">Prev</button>
<button class="nextButton">Next</button>
JS（需要jQuery）：jsfiddle
$(function() {
var img = 1;
var min = 1;
var max = 4;
$('.prevButton').on('click',function(e) {
if (img > min) {
img--;
changeImage();
}
});
$('.nextButton').on('click',function(e) {
if (img < max) {
img++;
changeImage();
}
});
$('img').on('click',function(e){
img = $(this).attr('id');
changeImage();
});
function changeImage() {
$('img').removeClass('myBorder'); // Removes all Borders
$('#' + img).addClass('myBorder'); // Applies Image Change
}
});
