js is not defined error

Question

How can I get the error message on a good way to solve? Error message: timetotal is not defined.

 $(document).ready(function() {
    if (typeof(timeleft) !== 'undefined') {
        Chrono.update();
    }
    $('a.add_other_answer').click(function() {
        addAnswer();
    });
});

Chrono = {
    warning: timetotal * 0.25,
    critical: timetotal * 0.05,

    update: function() {
    ...
    ...

@Wolfy87: It seems it is not ;) @lander: You have to define timetotal somewhere... — Felix Kling

This seems pretty self-explanatory, even with your code example being incomplete.

timetotal is most likely undefined at this line, since it is passed as a property of the object Chrono:

warning: timetotal * 0.25,

You are most likely incrementing timetotal in your Chrono.update method, but that is too late: the property should have an initial value if you want to multiply it with 0.25 or 0.05.

Solution:

var timetotal = 0;

Chrono = {
    warning: timetotal * 0.25,
    critical: timetotal * 0.05,

Edit: I see you got it fixed...;) Edit2: The last example won't work as this will not refer to Chrono but probably to windows. Edit3: This won't work either as Chrono is not defined yet when Chrono.timetotal * 0.25 is executed ;) (there is no way to access a property of an object while defining another property).

@Felix noticed it before your comment and edited my post :) edit: fixed the second error as well now! Doh! :)

Please see the third edit in my comment ;) But +1 from me anyway :)

Haha clearly need another espresso. I'll just remove the second example alltogether and skip JS programming for the day. Thanks for the tips.
