Copy content from textarea to input and trim characters
<p>First time here :)</p>

<p>I have a textarea and an input and I would like that, when something is typed into the texarea, it copies it to the input onkeypress. But the input must be limited to 10 characters. Then I would like to add 5 numbers to the end of the value of the input</p>

<p>EG:
Textarea content: "Hello world, how are you?"
Input content: "Hello worl12345"</p>

<p>I have tried <a href="http://jsfiddle.net/bxHQ5/" rel="nofollow">this</a>  and <a href="http://jsfiddle.net/4kS65/523/" rel="nofollow">this</a><br>
but on the second one I think its really messed up code and requires some "cleaning". Besides, it lacks the function of adding 5 numbers at the end.</p>
