jQuery validator plugin之Selector

原文

:unchecked Selector

Selects all elements that are unchecked.

• jQuery( ":unchecked" )

  • Inversion of :checked.

:filled Selector

Selects all elements with a filled value.

• jQuery( ":filled" )

filled means any value, but not only whitespace.

The implementation does a check like this: jQuery.trim(value).length > 0

:blank Selector

Selects all elements with a blank value.

• jQuery( ":blank" )

Blank means either no value at all or only whitespace.

The implementation does a check like this: jQuery.trim(value).length == 0
