Use select onChange to change example text in input box

Use select onChange to change example text in input box

Hey guys,

I'm quite new to jQuery but love learning new tricks. I have a search box
with a labelOver applied for the hint text and a select dropdown with 4
options. I would like to change the hint text depending on which option is
selected.

Eg if the user selects "People" the hint text will read "eg. John Smith", if
they pick "Year" the hint text will read "1985".

Many thanks in advance for your help,
Jordan
