通过位置的简单 jquery 滑块

Question

伙计们！我对简单滑块的简单 js 有疑问。它适用于左侧位置：-=999px；我的 js 为按钮更改 class 以使其处于非活动状态，但按钮仍然有效。我想念哪里？我需要禁用我点击的按钮。

$(function(){   
var slideWidth = $('#slider ul li').width();
$('a.control_next').click(function() {
  
  $('ol > li:first-child > a').removeClass('active');
  $('ol > li:last-child > a').removeClass('control_next');
  $('ol > li:first-child > a').addClass('control_prev');
  $('ol > li:last-child > a').addClass('active');
 
  $('#anim').animate({
    
    left: "-=920",
    
  }, 500, function() {
});
});

$('a.control_prev').click(function() {
  $('ol > li:last-child > a').removeClass('active');
  $('ol > li:last-child > a').addClass('control_next');
  $('ol > li:first-child > a').addClass('active');
  $('ol > li:first-child > a').removeClass('control_prev');

  $('#anim').animate({
    
    left: "+=920",
    
  }, 500, function() {
})
 
});

});

#slider {
 overflow: hidden;
 padding-left: 0;
 padding-right: 0;
}
#slider ul {
  position: absolute;
  overflow: hidden;
  width: 1000%;
  margin: 0;
  padding: 0;
  height: 200px;
  list-style: none;
}
#slider ul li {
 float: left;
 width: 920px;
 
}
ol{
 margin: 200px auto 0 auto;
 padding: 30px 20px;
 list-style: none;
 bottom: 0px;
 text-align: center;
}
ol > li {
 margin: 0 6px;
 display: inline-block;
}
ol > li > a{
 width: 11px;
 height: 11px;
 display: block;
 background: #f7f7f7;
 cursor: pointer;
 border-radius: 20px;
 box-shadow: inset 0 0 3px #a9afb3;
}
ol > li > a:hover:not(.active) {

尝试使用标志并在每个相应的处理程序中设置它们，例如

$(function() {
  var slideWidth = $('#slider ul li').width();
  var next = true;
  var prev = false;
  $('a.control_next').click(function() {
    if (next) {
      $('ol > li:first-child > a').removeClass('active');
      $('ol > li:last-child > a').removeClass('control_next');
      $('ol > li:first-child > a').addClass('control_prev');
      $('ol > li:last-child > a').addClass('active');

      $('#anim').animate({

        left: "-=920",

      }, 500, function() {});
      next = false;
      prev = true;
    }

  });

  $('a.control_prev').click(function() {
    if (prev) {
      $('ol > li:last-child > a').removeClass('active');
      $('ol > li:last-child > a').addClass('control_next');
      $('ol > li:first-child > a').addClass('active');
      $('ol > li:first-child > a').removeClass('control_prev');

      $('#anim').animate({

        left: "+=920",

      }, 500, function() {})

    }
    next = true;
    prev = false;
  });

});
