Question

当用户将鼠标悬停在 anchor 上时，除了悬停的 anchor 之外的每个 anchor 都会改变颜色。假设有 link1 link2 link3。如果用户将鼠标悬停在 link1 上，我希望更改 link2 和 link3 的颜色。和其他人一样。

这是我到目前为止的尝试 link on codpen

 a:hover{color:green}
 #link1:hover{color: originalcolor}
 #link2:hover{color: originalcolor}
 #link3:hover{color: originalcolor}

Answer 1

这可以使用 jQuery hover() 函数来实现，如下所示 -

$( "a" ).hover(
  function() {
    $("a").not($(this)).css("color","green");
  },function(){
  $("a").css("color","white");
  });
