Question

我用jQuery创建了一个切换内容按钮。当它切换时，我在底部添加不同的颜色三角形按钮。此外，不是切换按钮I的三角形，而是切换包含哪个按钮处于活动状态的内容。你可以在这里找到所有代码

<div class="variation">
                    <h2>Вариант размещения</h2>

我只是觉得它不是像我一样做jQuery脚本最简单的方法。所以，有人可以告诉最简单的方式，以及它是如何工作的，因为我尝试了不同的方法，但没有得到真正的结果。 JS小提琴http://jsfiddle.net/mzneo2sr/

Answer 1

您的脚本似乎按预期工作，所以我不清楚您的问题。然而，所有这些都可以简化为：

$('.content-link button').click(function () {
    var idx = $(this).closest('.content-link').index();

    $('.content-link button').removeClass('active-link');
    $(this).addClass('active-link');

    $('.content-panel').hide();
    $('.content-panel').eq(idx).show();
});

Demo

请注意，我已经为您的类似元素添加了一些常用类。类是一组类似的实体。

将类分别用作ID和目标元素并不是一个好主意。使用相对DOM遍历只编写一次代码。

Answer 2

这是您更新的小提琴：http://jsfiddle.net/mzneo2sr/3/

通过简单的属性（data-targetDiv）添加到您的按钮，您可以使用更少的代码实现此目的。

HTML添加：

<button type="button" class="btn btn-warning pr-bt" data-targetDiv="premium-text">Warning</button>

<button type="button" class="btn btn-success vip-bt" data-targetDiv="vip-text">Success</button>

<button type="button" class="btn btn-default usual-bt" data-targetDiv="usual-text">Default</button>

您的新点击事件：

$('.bt-group button').on('click',function(){
     var $this=$(this);
     $('.bt-group').find('button').removeClass('active-link');
     $this.addClass('active-link');
     $('.list-group').hide();
     $('.' + $this.attr('data-targetDiv')).show();
 });
