javascript - Primitive value returned from constructor will be lost -

i created function:

function checkhidden(el){ homecoming $(el).css('display')!='none' }

my ide warns me that:

primitive value returned constructor lost when called 'new'

actually when phone call this:

var = $("#catalog-body > div").filter(function(){return checkhidden(this)})

it doesn't work , doesn't cut down set of elements unhidden ones. please explain me issue. have giant lack of knowledge.

jquery has built in. can utilize :visible selector. can do:

var all=$("#catalog-body > div").filter(':visible')

to visible elements.
