Question

我的代码有效，直到：当我点击折叠或展开全部它工作并更改按钮文本从全部折叠全部展开。唯一的问题是：当我通过点击标题打开或关闭所有面板时，它也应该更改按钮的文本。

我希望我已经解决了我的问题。

在此示例中，我还没有包含Jquery和bootstrap外部文件。但您可以在以下链接中找到示例。

Jquery的

     $('.expand-all').click(function(){
     var $this = $(this);
     $this.toggleClass('collapse-all');
     if($this.hasClass('collapse-all')){
     $this.text(' Expand All');
     $('.panel-collapse.in')
     .collapse('hide');
     } 
     else {
     $this.text('Collapse All');
     $('.panel-collapse:not(".in")')
     .collapse('show');
     }
     });

Answer 1

这将解决您的问题

$(".panel-heading a").click(function(){
    setTimeout(function(){
        if($(".collapsed").length == $(".panel-heading").length){
            $(".btn-default").text(' Expand All');
          if(!$('.expand-all').hasClass('collapse-all')){
               $('.expand-all').addClass('collapse-all')
           }
        }else{
            $(".btn-default").text('Collapse All');
        }
    },100)    
})

Answer 2

this怎么样？

CODE：

$('.expand-all').click(function(){
    var $this = $(this);
    if($this.hasClass('collapse-all')){
        $this.text(' Expand All');
        $('.panel-collapse.in').collapse('hide');
        $this.removeClass('collapse-all');
    } else {
        $this.text('Collapse All');
        $('.panel-collapse:not(".in")').collapse('show');
        $this.addClass('collapse-all');
    }
});

$('#accordion').on('show.bs.collapse hide.bs.collapse', function (obj) {
    var $this = $(this);
    var $expand = $('.expand-all');
    if(obj.type=="show"){
        $expand.text('Collapse All').addClass('collapse-all');
    }
    else{
        if($('.collapse.in').not(obj.target).length == 0){
            $expand.text('Expand All').removeClass('collapse-all');
        }
    }
});

同时将collapse-all类添加到按钮

<a href="#" class="btn btn-default expand-all collapse-all">Collapse All</a>
