Question

我在同一页面上有多个Bootstrap手风琴，并注意到任何一个手风琴的事件触发器都可以影响所有（即在一个手风琴上打开/关闭会影响所有手风琴。）

在不更改标记且不使用$（this）的情况下，有没有办法确定以下示例的范围？： https://jsfiddle.net/terra823/kgrjg2z3/1/

的Javascript

$('.closeall').click(function(){
  $('.panel-collapse.in')
    .collapse('hide');
});

$('.openall').click(function(){
  $('.panel-collapse:not(".in")')
    .collapse('show');
});

Answer 1

当然，请使用手风琴的array index，例如：

fwrite

这将仅关闭第一项。

Answer 2

实际上，您的JavaScript事件同时针对.panel-collapse。您应该仅定位.container范围中的面板，如下所示：

// For close all button
$('.closeall').click(function(){
    $(this).closest('.container').find('.panel-collapse.in').collapse('hide');
});

// For open all button
$('.openall').click(function(){
    $(this).closest('.container').find('.panel-collapse:not(".in")').collapse('show');
});

享受。

Answer 3

使用$(this)。您可以轻松解决此问题。

请使用以下代码

$('.closeall').click(function(){
  $(this).parent().find('.panel-collapse.in').collapse('hide');
});

$('.openall').click(function(){
  $(this).parent().find('.panel-collapse').collapse('show');
});
