How can I call a userfunction onClick with a button?

YvoK

I use a button in my webapp, and I want to call a function when the button is clicked. It did not work, so I tried it again with some simple code.
The simple code that I tested on is:

<div>async () => {</div><div>&nbsp; &nbsp; console.log("Test");&nbsp; <br>}</div>

And the code on the onClick of the button is:

await UserFunction.Test()

When I click on the button, the userfunction won't run. How can I fix this?

Hi, 

I saw that you're trying to use `console.log` in your `UserFunction.Test`. This method prints content to the browser's console, which is suitable for viewing debug information when opening a deployed application in a browser.

If you want to display debug information on Flexpandent, you should use `Logger.i()`, which supports printing messages like strings, numbers, and more, And make sure to check 'Show debug log on the tech pendant UI' when deploying the webpage.

Thanks.

Thank you for the reply. I will use this logger in my code from now on.

It still does not fix the problem with calling the`UserFunction.Test` when I press a button. Do you have a solution for this?

In Appstudio version 1.1.0, I get an error message when I press the button. the following popup will appear:

Event Trigger Error<br>'UserFunction' not defined<br>

I have the same problem — is there already a solution for this so that the functions can be used?
