jquery - check whether the empty string exist in an input field -


how check whether input form has empty string? tried use code below didn't work.

e.which == 13 catch whether user press enter key, secondly !== "" prevent data input if there nothing typed.. why didn't work? logic seem ok.. first 1 worked, second didn't.. 

if(e.which == 13 && $(inputbar) !== ""){ // }

you should checking $(inputbar).val() not $(inputbar) return object not value of text in input box
