    time based progress bar (countdown)

    I have looked and looked and looked but i can't find what i'm looking for.

    I need a progress bar that counts down and shows the time inside the bar as it is counting down.

    it doesn't have to be fancy it just has to work.

    what i'm doing now is a periodic update using ajax and then changing the size of a bar in css.

    it works but it is not ideal.

    does anyone know where i can find a tutorial for creating a countdown bar?

    it can be jQuery or just javascript i'm getting half decent at both.

    thank you.

    awesome almost exactly what i need

    that's awesome,

    is there any way that i can reverse it so it counts down from the start time and goes down to zero.

    10 seconds remaining
    9 seconds remaining
    8 seconds remaining.

    etc etc??

    how do i set it up?

    how do i set it up?

    i loaded it up and the red progress bar starts on the left and builds to the right.

    i'd like it to be 100% at the start build or countdown from right to left.

    like a countdown clock.

    its' awesome and very close i just need to reverse the way it builds.

    from right to left instead of left to right.

    thanks.

    works perfect

    that's awesome works perfect.

    i have one question though.

    i tried to get an alert to fire when the timer reaches zero but any changes that i make break it.

    how to i get an alert('timed out'); to fire when the counter reaches zero?

    //
    // The effect is executed by an event call to function 'A.animate(10,800 ,5000,[10,800]);'
    // where:
    //  A           = the global referencing the script instance.                                 (variable)

    //  parameter 2 =  period of time between the start and finish of the effect in milliseconds. (digits or defaults to previous or 0(on first call) milliSeconds)
    //  parameter 3 = (optional) to scale the effect time on a specified minimum/maximum.         (array, see Note 3)
    //                 field 0 the minimum value. (digits)
    //                 field 1 the maximum value. (digits)
    //  parameter 3 = (optional) the type of progression, 'sin', 'cos' or 'liner'.                (string, default = 'liner')
    //                 'sin' progression starts fast and ends slow.
    //                 'cos' progression starts slow and ends fast.
    //
    //  Note 1:  Examples modes: 'left', 'top', 'width', 'height', 'opacity.
    //  Note 2:  The default units(excepting opacity) are 'px'.
    //           For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
    //  Note 3:  The scale is of particular use when re-calling the effect
    //           in mid progression to retain an constant rate of progression.
    //  Note 4:  The current effect value is recorded in A.data[0].
    //  Note 5:  A function may be called on completion of the effect by assigning the function
    //           to the animator intance property .Complete.
    //           e.g. [instance].Complete=function(){ alert(this.data[0]); };
