当页面加载/重新加载时我想要保留第一个带有背景颜色的按钮,当单击另一个按钮时,第一个按钮颜色会消失。
我为它制作了这段代码:
value = Lo

$(document).ready(function(){
$(".target1").css("background-color", "red");
$(".target1").css("color", "white");
$(".target2").click(function(){
$(".target1").css("background-color", "transparent");
$(".target1").css("color", "black");
$(".target2").css("background-color","red");
});
});

我有很多其他按钮,所以在Jquery中做这种代码我觉得这不是最好的做法......我需要帮助向我解释一个更好的方法吗?我将感激你的教诲!

您需要this
功能:
$(document).ready(function() {
$(".target").css("color", "black").css("background-color", "white");
$(".target1").css("background-color", "red");
$(".target1").css("color", "white");
$(".target").click(function() {
$(".target1").css("background-color", "none");
$(".target").css("color", "black").css("background-color", "white");
$(this).css("background-color", "red");
});
});
<button class="target target1" type="button">
Button 1
</button>
<button class="target target2" type="button">
Button 2
</button>
<button class="target target3" type="button">
Button 3
</button>
<button class="target target4" type="button">
Button 4
</button>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
希望这有帮助!

你可以这样缩小:
$(document).ready(function() {
$(".btn").click(function() {
$('.active').removeClass('active');
$(this).addClass('active');
});
});
.active {
background-color: red;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="collapse3">
<ol>
<button class="target1 btn" type="button" onclick="setURL('imgs/projects/FAB/F01-Fabrication/1.html')">F01-Fabrication-1</button>
<br>
<button class="target2 btn" type="button" onclick="setURL('imgs/projects/FAB/F01-Fabrication/2.html')">F01-Fabrication-2</button>
<br>
<button class="target3" type="button" onclick="setURL('imgs/projects/FAB/F01-Fabrication/3.html')">F01-Fabrication-3</button>
<br>
<a class="target4" type="button" onclick="setURL('imgs/projects/FAB/F01-Fabrication/4.html')">F01-Fbuttonbrication-4</button><br>
<button class="target5" type="button" onclick="setURL('imgs/projects/FAB/F01-Fabrication/5.html')">F01-Fabrication-5</button><br>
</ol>
</div>

要设置多个属性,请尝试:
$("p").css({"background-color": "yellow", "font-size": "200%"});
在css()方法中传递一个对象。
