To make bookings more interactive, a timer can be used to refresh the bookings list while the user is making bookings and moving his mouse.
6
This requires changes mainly in the function that draws the table and timers need to be added to the code so that the redrawing function is called periodically.

<div class="descriptionheading">drawResult</div>
11
The function called <span class="interestingdescription">drawResult</span> is changed so that there is coloring depending on booking status and functionality for
12
making highlight bookings when the mouse is hovering over a booking slot.
16
<div class="descriptionheading">bookPosition</div>
17
The function called <span class="interestingdescription">bookPosition</span> is changed so that it can use a booking status variable.
21
<div class="descriptionheading">refreshBookingList</div>
22
The <span class="interestingdescription">refreshBookingList</span> function is called by the timer. The main difference is that the resource and bookingdate variables are global variables
23
updated by the <span class="interestingdescription">processinputbox</span> function. The processinputbox function does not call the <span class="interestingdescription">refreshBookingList</span> function directly, but relies on the timers to call the function.
