Multiple Buttons?

[ericalbers]

How does one define multiple custom buttons yet still get the data from the input: area?
The example at
https://jsfiddle.net/adamschwartz/Lrq84/)
Does not work
Say you have a input field for a name, and 3 custom buttons and when they are pressed, you'd like to know which one was pressed and the value of the name field?
I see this question asked all over, and every answer is incorrect or broken/deprecated.
Thanks
