我有一个按钮列表。当点击其中一个时,我想给所有其他按钮一个not-selected
类,它将文本颜色改为灰色并制作指针事件:无
我正在使用点击处理程序,不确定我使用感叹号!
是否正确,因为它一直将该类添加到我刚刚点击的按钮,而不是所有未点击的按钮。
$(".btn--list").on("click", function(){
!($(this).addClass("not-selected"));
)};
<ul>
<li><h2>Filters</h2></li>
<li class="filter--all"><button class="btn--list btn--all is-selected">Select All</button></li>
<li><h2>Decade</h2></li>
<li><button class="btn--list btn--1960">1960s</button></li>

答案 0 :(得分:7)
您在jQuery对象上使用.btn--list
运算符无效。为了达到您的要求,您可以选择所有.not(this)
元素,并使用$(".btn--list").on("click", function() {
$(".btn--list").not(this).addClass("not-selected");
});
排除当前元素。试试这个:
/* For demo purposes... */
.not-selected {
background-color: #c00;
pointer-events: none;
}
