javascript - Jquery: Is there some way to make val() return an empty string instead of 'undefined' for an empty list? -

-

with jquery, there way make val() return empty string instead of 'undefined' when called against empty list of elements?

e.g., have code:

var x = $('#my-textbox-id').not('.watermark').val();

the idea want value of textbox, want empty string if showing watermark (i don't want watermark value!).

the selector works, don't want 'undefined' - want empty string ''.

you can write (...).val() || "".

only use text fields; replace false or number 0 "".
