jQuery....
$('#test#2').css('color','blue');
推荐答案
使用任何元字符#$%&'()* +,。/:;< =>?@ [] ^`{|}〜作为名称的文字部分,必须用反斜杠转义:
To use any of the meta-characters such as !"#$%&'()*+,./:;<=>?@[]^`{|}~ as a literal part of a name, it must be escaped with with backslashes:
css方式:
#test\#1{
color: red;
}
jquery方法:
$('#test\\#2').css('color','blue');

Recommendation:
在您的ID 详细了解详情
ID和NAME令牌必须以字母([A-Za-z])开头,后跟任意数量的字母,数字([0-9]),连字符( - ),下划线(_),冒号(:)和句点(。)。
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").
所以,你可能还想知道id =test.1可以使用,对于这个也应该如上所述转义字符。
So, you may be also wondering id="test.1" can be used and for this too you should escape the character as described above.
