你能帮我与引导和JavaScript崩溃吗？我有两个崩溃卡。比你点击链接，首先应该卡可见。点击后应该表现出下一张牌，并首先应该消失。它的功能，但在第一次点击有两个卡。这就是第二次点击后修复。感谢ü的帮助。
HTML：
<div class="card text-center">
<div class="card-header ">
<a class="nav-link" id="spust" href="#">Kontaktní formulář</a>
</div>
<div id="kontakty">
</div>
<div class="collapse" id="konform">
</div>
</div>
使用Javascript：
var collapsestate = false;
jQuery('#spust').on("click",function(e) {
if (collapsestate == false){
$('#kontakty').collapse('hide');
$('#konform').collapse('show');
collapsestate = true;
}
else{
$('#konform').collapse('hide');
$('#kontakty').collapse('show');
collapsestate = false;
}
console.log(collapsestate);
});
在这个片段中的代码尝试......我觉得这个片段是按您的要求。
$(document).ready(function(){
var collapsestate = false;
$('#kontakty').collapse('show');
$('#spust').on("click",function(e) {
if (collapsestate == false){
$('#kontakty').collapse('hide');
$('#konform').collapse('show');
collapsestate = true;
}
else{
$('#kontakty').collapse('show');
$('#konform').collapse('hide');
collapsestate = false;
}
console.log(collapsestate);
});

<div id="kontakty" style="display:none">
