Hello,
i want to build a simple calculator. For this I would want to create 10 buttons for each digit and 6 buttons for plus, minus, multiply, divide, delete, equal.
Then a computation services that takes the label of the buttons pressed as input.
But here I am already stuck. I haven't found a way to pass a value for a button to a service. Logic; if button "4" was clicked, input parameter "digit" should be "4".
I have already tried setting a contextID and working with event routers but the problem is that the context ID should only be passed when the button is clicked, but it will always pass.
I would appreciate any help!
Thank you.
Solved! Go to Solution.
If you use an expression before the Event Router I believe this should work (to control when exactly the value is passed to the Event Router).
Can you please check if the example I built in attachment works? (it's not very optimized...)

Thank you so much!
So the only way would be to create more than 16 Expressions (one for each button)?
Hi again,
I think the expression router and event combo, even if it is a bit of work to write an expression for each button, could work. Thank you!
However can you think of a way to implement the logic, that unless a user clicks on one of the operator buttons, the numbers pressed should be appended?
So if i first click 1, then 2, it should be number 12.
I am also a bit clueless where to store the numbers and the operators that should be passed to the calculation service. In an non-persistent InfoTable thing property?
Thank you!
