我正在尝试制作一个可折叠的 div/面板/行。我想使用 jquery/javascript 添加箭头图标(右箭头和下箭头)。你知道如何在 jQuery 上翻译我的 CSS 代码吗？
这是我的 jQuery 代码:
$(document).ready(function(){
$(".collapse").on("hide.bs.collapse", function(){
$(".arrows").after().css({"content":"\e080","font-family": "Glyphicons Halflings"});
});
$(".collapse").on("show.bs.collapse", function(){
$(".arrows").after().css({"content":"\e114","font-family": "Glyphicons Halflings"});
});
});
这是我的 CSS 代码:
.arrows:after {
font-family: "Glyphicons Halflings";
content: "\e114";
}
.arrows.collapsed:after {
font-family: "Glyphicons Halflings";
content: "\e080";
}
这是我的 HTML 代码:
<div class="panel-group">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" href="#collapse1">Collapsible panel <span class="arrows"></span></a>
</h4>
</div>
<div id="collapse1" class="panel-collapse collapse">
<div class="panel-body">Panel Body</div>
<div class="panel-footer">Panel Footer</div>
</div>
</div>
</div>
最佳答案
检查这个片段。只需在隐藏和显示事件上切换类
$(".collapse").on("hide.bs.collapse", function() {
$(this).parent().find('.arrows').addClass('collapsed');
});
$(".collapse").on("show.bs.collapse", function() {
$(this).parent().find('.arrows').removeClass('collapsed');
});.arrows:after {
font-family: "Glyphicons Halflings";
content: "\e114";
}
.arrows.collapsed:after {
font-family: "Glyphicons Halflings";
content: "\e080";
