[jQuery] How do you handle 2 differents and 1 action?

[jQuery] How do you handle 2 differents and 1 action?


I have the following piece of code which checks if a user has pressed
the Enter key in a text input with id="text_input" and then performs
some action:
$(document).ready(function()
{
$("#text_input").keyup(function(e)
{
// Checks if the Enter key was entered
if(e.keyCode == 13)
{
// perform the action
}
});
});
I also have a button with id="push_button" that I wish will perform
the same action as above when clicked. How can I rewrite the above so
that I check for either of those two events and perform that one
action without code duplication?
