引導手風琴範圍問題

Question

我有相同的頁面上有多個引導手風琴，已經注意到該事件的任何一個手風琴觸發可影響所有（即開/關在一個手風琴特效全部手風琴。）

不改變標記和不使用$（本），是有辦法的範圍下面的例子？： 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

實際上，您的JavaScript事件同時針對.panel-collapse。您應該只將目標面板放在.container範圍內，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 2

肯定的是，使用手風琴的array index，例如：

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

這將只關閉第一個項目。

Answer 3

通過使用$(this)。您可以輕鬆解決此問題。

請使用下面的代碼

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

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