你不能add完了接着一个.$(this)啊,这个没得这个语法,
先remove,再add,如果你的b是有很多的话,就应该把b全部取出来,然后removeClass
然后再根据你点击的,取到点击的对象下面的b进行addClass
其他类似问题
问题1：jquery,有段代码（不全）,$(this).parent().children().removeClass("db"); $(this).addClass("db");其中parent().children()这两个写在一起是什么意思?[英语科目]
parent() 获得当前匹配元素集合中每个元素的父元素
children() 方法返回匹配元素集合中每个元素的子元素
也就是说当前元素的父亲的子元素,换言之就是兄弟元素
问题2：求corrinne may的what child is this歌词现在搜到的都不太对,希望能有正确完整的
corrinne may--what child is this
What Child is this,who laid to rest,
On Mary's lap is sleeping?
Whom angels greet with anthems sweet
While shepherds watch are keeping?
This,this is Christ the King
Whom shepherds guard and angels sing.
Haste,haste to bring Him laud,
The Babe,the Son of Mary.
Why lies He in such mean estate
Where ox and ass are feeding?
Good Christian,fear:for sinners here,
The silent Word is pleading.
Nails,spear,shall pierce Him through,
The Cross be borne,for me,for you:
Hail,hail,the Word made flesh,
The Babe,the Son of Mary!
So bring Him incense,gold and myrrh;
Come peasant,king to own Him.
The King of Kings salvation brings;
Let loving hearts enthrone Him.
Raise,raise,the song on high,
The Virgin sings her lullaby:
Joy joy for Christ is born,
The Babe,the Son of Mary!
