Call JavaScript function by pressing button

Flow
41

Is this line correct: UI.getCurrent().getPage().executeJs(“register(window.warRequest”)

42

I am confused about the “(” right after register.

43

Are you sending the POST request from the server or from the JavaScript?

44

JavaScript

45

I must place somewhere the server url.

46

Then what I’ve been telling you is right

47

You only need to do one thing on the server: invoke a JavaScript function after a button is clicked.

48

The data is all available in the browser.

49

So what I did so far is correct?

50

Assuming you followed my instructions, yes

51

Running the code will result into this:

52

Maybe it helps if I show you the full code from Js file.

53

You can find it here: https://github.com/privacyidea/webauthn-client/blob/master/pi-webauthn.js

54

You need to define the webAuthnRegisterRequest in your JavaScript

55

I did that. You showed me that.

56

Then I recommend you put a breakpoint in your JavaScript code and see what happens. Hint: you can use the debugger; statement in JavaScript to do that.

57

There are possibly two wrong things:

  1. I put the defintion of webAuthnRegisterRequest in the wrong place.
  2. The line UI.getCurrent().getPage().executeJs(“register(window.warRequest”) is not correct.
58

At least you’re missing one ) from the second one, before the latter "

59

Added it but no result.

Can you show both your java and Js code? It seems to me you are not passing the parameter correctly
