Advice Generator App using AdviceSlip API

When using the randomly generated link from the adviceslip API, the javascript that I wrote would fetch the URI once, then would not reload a different message even if the function was called again. To workaround this, I created a random number generator. This random number is appended to the end of the API uri to get a pseudo-random URI. Is there a better way to do this? What would best practices be?
