$(this).addClass('class').siblings('class').removeClass('class')的作用
$(this).addClass('class'):为当前元素添加'class'类(供选择器使用 - - )
$(this).siblings('class'):查找当前元素的所有类名为 "class" 的所有同胞元素,也就是有相同类名的同胞元素。(同胞就是拥有相同的父元素)
$(this).removeClass('class'):为当前元素去除'class'类,与addClass作用相反
$(this).addClass('class').siblings('class').removeClass('class'):作用是 给当前元素添加'class'类并查找同胞元素再去除同胞元素的'class'类
