jQuery plug-in kinMaxShow extended effect usage example_jquery

The example in this article describes the usage of the jQuery plug-in kinMaxShow extended effect. Share it with everyone for your reference. The specific analysis is as follows:

The focus image on Alipay’s homepage uses the kinMaxShow extension effect (Alipay used it some time ago, I don’t know if it is still this way now. In addition, the animation effect of Alipay’s focus image is browser-specific, and there is no animation in IE8 and below browsers. Purely static, animation will only appear in modern browsers such as Google and Firefox.) This is just a small example of the kinMaxShow extension. You can play more effects yourself. The code is as follows:

javascript code:

<script src="js/jquery-1.10.2.min.js" type="text/javascript"></script>
<script src="js/jquery.kinMaxShow-1.0.min.js" 
type="text/javascript"></script>
<script type="text/javascript">
$(function(){
 $("#kinMaxShow").kinMaxShow({
 //设置焦点图高度(单位:像素) 必须设置 否则使用默认值 500
 height:400,
 //设置焦点图 按钮效果
 button:{
  //设置按钮上面不显示数字索引(默认也是不显示索引)
  showIndex:false,
  //按钮常规下 样式设置 ，css写法，
  //类似jQuery的 $('xxx').css({key:value,……})中css写法。  
  //【友情提示：可以设置透明度哦 不用区分浏览器
  //统一为 opacity，CSS3属性也支持哦
  //如：设置按钮圆角、投影等，只不过IE8及以下不支持】  
  normal:{background:'url(images/button.png) no-repeat -14px 0',
  marginRight:'8px',border:'0',right:'44%',bottom:'20px'},
  //当前焦点图按钮样式 设置，写法同上
  focus:{background:'url(images/button.png) no-repeat 0 0',
  border:'0'
  }
 },
 //焦点图切换回调，每张图片淡入、淡出都会调用。
 //并且传入2个参数(index,action)。
 //index 当前图片索引 0为第一张图片，
 //action 切入 或是 切出 值:fadeIn或fadeOut
 //函数内 this指向 当前图片容器对象 可用来操作里面元素。
 //本例中的焦点图动画主要就是靠callback实现的。
 callback:function(index,action){
 switch(index){
  case 0 :
  if(action=='fadeIn'){
  $(this).find('.sub_1_1').animate({left:'70px'},600)
  $(this).find('.sub_1_2').animate({top:'60px'},600)
  }else{
  $(this).find('.sub_1_1').animate({left:'110px'},600)
  $(this).find('.sub_1_2').animate({top:'120px'},600)
  };
  break;
  case 1 :
  if(action=='fadeIn'){
  $(this).find('.sub_2_1').animate({left:'-100px'},600)
  $(this).find('.sub_2_2').animate({top:'60px'},600)
  }else{
  $(this).find('.sub_2_1').animate({left:'-160px'},600) 
  $(this).find('.sub_2_2').animate({top:'20px'},600)
  };
  break;
  case 2 :
  if(action=='fadeIn'){
  $(this).find('.sub_3_1').animate({right:'350px'},600)
  $(this).find('.sub_3_2').animate({left:'180px'},600)
  }else{
  $(this).find('.sub_3_1').animate({right:'180px'},600) 
  $(this).find('.sub_3_2').animate({left:'30px'},600)
  };
  break;   
 }
 }
 });
});
</script>

HTML code:

 <!--如果需要附加内容在焦点图内部 需要用一个div包裹起来，
