我有一个项目A，B，C，D，E的列表。您在这些列表项目之一上单击的每个项目都有一个引导类“ collapse”，其中显示了一个带文本的div。一切正常。但是，您必须再次单击列表项以折叠包含文本的div。
我试图确保在单击列表项时，所有其他openend div立即关闭。
我找到了一些提到要使用“数据父级”的内容，但是如下面的代码片段所示，这是行不通的。要查看问题，请查看代码段并展开代码段。
要复制我的问题，请执行以下步骤：
我试图确保您只看到与您单击的div的ID有关的文本。
SPOpen(1,9600,1,0,8)
SPOpen( "COM1" )
SPSendString(1, "*IDN?" )
string message
number test
message = SPReceiveString(1,8,test)
Result("Acquisition "+message+" "+test+"\n")
SPClose(1)
答案 0 :(得分：1)
您可以使用类似jquery的
<script type="text/javascript">
$(document).ready(function(){
$('[data-toggle="collapse"]').click(function(event) {
if ($('.collapse.in').length > 0) {
$('.collapse.in').collapse('hide')
}
});
})
</script>
在data-toggle="collapse"单击时，意味着在列表项上单击，所有打开的div（带有.in类）都被collapse function关闭。
