javascript - jQuery $.inArray() returns 0 -

-

if have array ('a', 'b') , check $.inarray('a', thearray); index, 0, , false. need check result further , it's annoying...

is there quick method trough can true/false, , not indexes?

basically have string in html5 data attribute: data-options="a,b,c" , 3 a, b, c variables in javascript must take true/false values based on what's inside data-options...

you can achieve invoking binary not operator.

if( ~$.inarray('a', thearray) ) { }
