引导手风琴作用域问题

Bootstrap Accordion Scope Issue

本文关键字：问题 作用域 手风琴      更新时间：2023-09-26

我在同一页面上有多个引导手风琴，并且注意到任何单个手风琴的事件触发器都可以影响所有(即单个手风琴的打开/关闭影响所有手风琴)

在不改变标记和不使用$(this)的情况下，是否有一种方法可以限定下面示例的范围?：https://jsfiddle.net/terra823/kgrjg2z3/1/

Javascript 

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

实际上，JavaScript事件的目标是.panel-collapse。您应该只针对.container作用域中的面板，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');
});

。

当然，使用手风琴的数组索引，例如:

*/$('.closeall').click(function(){
    $('.panel-collapse.in')
    .eq(0)  // item at the 0. position
    .collapse('hide');
  });

这将只关闭第一项。

使用$(this)。你可以很容易地解决这个问题。

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');
});
