Attribute Selectors
1. [attr]
eg: input[type] =>所有设置了type属性的input标签都生效(无论type的值是什么)
2. [attr="value"]
eg: input[type="text"]
3.Substring Matching Attribute Selectors
>> ^ Begin With Selector
a[href^="http://"]
>> $ End With Selector
a[href$=".pdf"]
>> * Contains Selector
a[href*="goo"] 包含,不区分大小写
4. [attr~=value]
eg:
class="title"
class="title colorMe"
>> 常规 [class="title"] 完全匹配,第1个生效
>> ~ [class~="title"] 子串匹配,1、2都生效
>> 常规 [class="colorMe"] 完全匹配,都不生效
>> ~ [class~="colorMe"] 子串匹配,第2个都生效
>> 常规 [class="title colorMe"] 完全匹配,第2个生效
>> 常规 [class="colorMe title"] 完全匹配,都不生效
5. [attr|=value]
eg:
lang="en"
lang="en-es"
lang="es"
>> Selecting [lang|=en] : [lang|=en] 1、2生效(|= 对于连接符可以生效)
>> Selecting [lang|=e] : [lang|=e] 都不生效
>> Selecting [lang^=e] : [lang^=en] 都生效
>> [lang|=en],[lang|=es] 都生效
>> div[lang|=es] 第2个生效
