I have a textfield

Код HTML:

<input type="text" name="example" id="exmaple_test" title="Loremipsum text" placeholder="Lorem Ipsum" autofocus />

Now I want to do this:
Onclick I want it to add a particular text like when I click on the textarea I want the text to turn the value of the textarea to 'Yay'. Any idea how I can do this? I tried ****** but no luck. :/
