how to set color in table rows randomly with on click button?
<p>this is my code: <a href="https://goo.gl/WorXyI" rel="nofollow">link</a>  I have table with 9 row. on click button, one must change color randomly. if I click button once more, it must continue change color randomly</p>

<p>I don't want random color.
I want next thing:</p>

<p>first click: random row must be colorized red</p>

<p>second click:  random row must be colorized red</p>

<p>and so on...</p>
