[jQuery] formatting/defining variable values
Hello
I'm collecting a number of values from various form elements:
textfield, radio, checkbox.
since some of the fields aren't require on my form, when I POST their
values they are returned as 'undefined'
is there a way in Jquery that would allow me to set all variables that
are undefined with a given value like "N/A" or even just ""?
for example, after the form is submitted, I'm using the following code
to populate my values:
//cancer vars
var cancerVal = $("input[name='cancer']:checked").val();
var cancerTypeVal = $("#cancerType").val();
var cancerDateVal = $("#cancerDate").val();
var chemoCanVal = $("input[name='chemoCan']:checked").val();
var radiationCanVal = $("input[name='radiationCan']:checked").val();
var surgeryCanVal = $("input[name='surgeryCan']:checked").val();
var otherCanMoreVal = $("input[name='otherCanMore']:checked").val();
doing something like:
var chemoCanVal ="";
before the submit does not seem to help.
Alternately, if there is a way that I can use a function to replace
all instances of 'undefined' with another value after the form is
submitted, that too would work.
thanks in advance!
cheers,
