难以在单击时更改UL内部的IMG Src，并具有单击时已存在的功能

Question

您可以在此处查看示例： https://blennd.com/

向下滚动到“我们做什么”。

“混合”时有4个svg图像，默认情况下1个处于活动状态。当您单击下一个图像时，将在容纳所有图像的容器下方显示一组新的文本。

这是我要实现的确切功能。我再次去了Codepen并进行了试验。这是我想出的：

阻止我前进的步骤是单击每个img时更改img src。我想要的全部功能都在那里。

如果除了拥有img src之外，还有另一种更好的方法，我也很乐意。

Answer 1

这可以通过在标签中使用两个<img>和一些CSS代码来实现。

  

注意：有效图像和无效图像在这里有所不同，您可以进行相应的更改。

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");
    });
