jquery - How should i get some value from javascript object and check for null -

-

i getting element as

   var minpriceperinputfield = $("input#a"+indexnr);

the element can present or not also. getting [object object] thing. have no idea this. receiving [object object] when element not there.

use 

if(   $(minpriceperinputfield).length === 0);

means null. no element selector.
