$ (' input[name~= "man"] ') the name value is separated by a white space character, and there is a man input in the word, for example: <input name= "Milk man"/>
$ (' input[name!= ' newsletter "] ') name is not equal to newsletter input, but this property selector is a selector extended by jquery, not a specification of CSS, using the [name!=" value "] does not take full advantage of the native Dom's Queryselectorall method to improve performance, so in order to improve the performance of modern browsers, you can use $ ().
