I would like to put a button in a aspx page calling two JavaScript functions.
So I added the code :

<a onclick="javascript:'registerTraining();confirmRegisterTraining()';" class="btn orange height_19 submit"><span>SEND</span></a>
RegisterTraining function sends an email to register for a training to an internal service
ConfirmRegisterTraining function sends an email to the user for confirmation of the request.

I wanted to know how to make a call 2 functions ?
Is that the first function is executed and after the second function ?
Do you have any specific recommendations ?
I did a search but not found much info on it.
