兄弟姐妹是否有错误(' .xx')? 单击时不想重复图像 对不起,我的英语很糟糕:(
$(document).ready(function() {
//$(".ok").removeClass("imga");
//$('.ok2').removeClass('imga').siblings('.ok2').addClass("imga");
$('.item').click(function() {
var id = $(this).attr('id');
var xx = "ok" + id;
$('.ok' + id).removeClass('imga').siblings('.xx').addClass("imga");
$(this).addClass('active').siblings().removeClass('active');
});
});

.active {
font-weight: 900;
color: blue;
}
.hover {
color: blue;
}
.imga {
-webkit-filter: grayscale(1);
filter: grayscale(1);
margin: auto;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="item" id="1">
<img class="ok1 imga" src="http://icons.iconarchive.com/icons/ampeross/qetto/128/icon-developer-icon.png"><br>

为什么不使用active
类来更改图像显示?
$('.item').click(function(){
$(this).addClass('active').siblings().removeClass('active');
});
&#13;
.active{
font-weight:900;
color:blue;
}
.item:not(.active) img {
-webkit-filter: grayscale(1);
filter: grayscale(1);
margin:auto;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="item" id="1"><img class="ok1 imga" src="http://icons.iconarchive.com/icons/ampeross/qetto/128/icon-developer-icon.png"><br>image 1</div>
<div class="item" id="2" width="50" width="50"><img class="ok2 imga" src="http://icons.iconarchive.com/icons/ampeross/qetto/128/icon-developer-icon.png"><br>image 2</div>

您不需要ID,只需将该类添加到所有img中,然后将其删除以用于当前的
$(document).ready(function() {
$('.item').click(function() {
$(this).addClass('active').siblings().removeClass('active');
$('.item img').addClass('imga');
$(this).find('img').removeClass('imga');
});
});
&#13;
.active {
font-weight: 900;
color: blue;
}
.hover {
color: blue;
}
.imga {
-webkit-filter: grayscale(1);
filter: grayscale(1);
margin: auto;
}

$(document).ready(function() {
$('.item').click(function() {
var $this = $(this);
$this.children().removeClass('imga').end().addClass('active');
$this.siblings().removeClass('active').children('img').addClass('imga');
});
});
.active {
font-weight: 900;
color: blue;
