javascript - 难以更改 UL 内的 IMG Src，点击时已存在点击功能

Question

您可以在此处查看示例: https://blennd.com/

向下滚动到“我们做什么”。

Blendd 上有 4 个 svg 图像，其中 1 个默认处于事件状态。当您单击下一个图像时，一组新文本会出现在包含所有图像的容器下方。

这正是我要实现的功能。我又去codepen做了实验。这是我想出的:

阻碍我的步骤是在单击每个 img 时更改 img src。除此之外，我想要的全部功能都在那里。

如果除了拥有 img src 之外还有其他更好的方法，我也愿意接受。

Answer 1

这可以通过两个 <img> 来实现在选项卡和一些 CSS 代码中。

Note: Active and Inactive images are different here, you can change accordingly.

这是添加的 CSS。

ul.tabs li.active > img.img-inactive {
    display: none;
}
ul.tabs li.active > img.img-active {
    display: block;
}
ul.tabs li > img.img-active {
    display: none;
}

// tabbed content
    // http://www.entheosweb.com/tutorials/css/tabs.asp
    $(".tab_content").hide();
    $(".tab_content:first").show();

  /* if in tab mode */
    $("ul.tabs li").click(function() {
		
      $(".tab_content").hide();
      var activeTab = $(this).attr("rel"); 
      $("#"+activeTab).fadeIn();		
		
      $("ul.tabs li").removeClass("active");
      $(this).addClass("active");

	  $(".tab_drawer_heading").removeClass("d_active");
	  $(".tab_drawer_heading[rel^='"+activeTab+"']").addClass("d_active");
	  
    });
	/* if in drawer mode */
	$(".tab_drawer_heading").click(function() {
      
      $(".tab_content").hide();
      var d_activeTab = $(this).attr("rel"); 
      $("#"+d_activeTab).fadeIn();
	  
	  $(".tab_drawer_heading").removeClass("d_active");
      $(this).addClass("d_active");
	  
	  $("ul.tabs li").removeClass("active");
	  $("ul.tabs li[rel^='"+d_activeTab+"']").addClass("active");
    });
	
	
	/* Extra class "tab_last" 
	   to add border to right side
	   of last tab */
	$('ul.tabs li').last().addClass("tab_last");
