我编写了以下代码,当您点击按钮时,整个样式将被更改。
$(".Button1").click(function() {
$(this).toggleClass('Button1Changed');
});
.Button1 {
background-color:#000000;
color:#ffffff;
}
.Button1Changed {
background-color:#ff0000;
color:#ffffff;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<button class="Button1">Button 1 - Click</button>
但现在我需要添加一些新按钮,如下面的代码。我希望当我点击“按钮2”时,“按钮1”的样式再次变为第一堂课!或者当我点击“按钮3”时,按钮2的样式再次改变&amp; ...
我该怎么做?!
$(".Button1").click(function() {
$(this).toggleClass('Button1Changed');
});
.Button1 {
background-color:#000000;
color:#ffffff;
}
.Button1Changed {
background-color:#ff0000;
color:#ffffff;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<button class="Button1">Button 1 - Click</button>
<button class="Button1">Button 2 - Click</button>
<button class="Button1">Button 3 - Click</button>
<button class="Button1">Button 4 - Click</button>

您可以使用.not()
方法排除当前元素,例如this
,并从其他元素中排除.removeClass()
。
$(".Button1").not(this).removeClass('Button1Changed');
$(".Button1").click(function() {
$(".Button1").not(this).removeClass('Button1Changed');
$(this).toggleClass('Button1Changed');
});

.Button1 {
background-color: #000000;
color: #ffffff;
}
.Button1Changed {
background-color: #ff0000;
color: #ffffff;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<button class="Button1">Button 1 - Click</button>
<button class="Button1">Button 2 - Click</button>
<button class="Button1">Button 3 - Click</button>
<button class="Button1">Button 4 - Click</button>

另一种方法可以基于.add():切换当前元素的类和最后更改的按钮:
$('.Button1.Button1Changed').add(this).toggleClass('Button1Changed');
$(".Button1").on('click', function(e) {
$('.Button1.Button1Changed').add(this).toggleClass('Button1Changed');
});
.Button1 {
background-color: #000000;
color: #ffffff;
}
.Button1Changed {
background-color: #ff0000;
color: #ffffff;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="Button1">Button 1 - Click</button>
<button class="Button1">Button 2 - Click</button>
<button class="Button1">Button 3 - Click</button>
<button class="Button1">Button 4 - Click</button>
