jQuery: how to use :checked, if my element is $(this)

how c开发者_C百科an I use the option :checked with $(this) in jQuery ?

i.e. $(this:checked) ?

$(this).filter(":checked");

or if you're testing it

if ($(this).is(":checked")){
    // ...
}

Like this:

if ($(this).is(':checked'))

Use is() method.

$(this).is(':checked') returns boolean.

The checkbox Node has its own property checked, so:

if (this.checked) ...

there is no need to make jQuery do a bunch of work by packaging that trivially simple check in a selector. The DOM version is perfectly readable.

try it $(':checked', $(this))
