Calling a method on load

How-to Discussions

How would I go about to call a method as soon as the app loads (without user interaction) or alternatively as soon as a specific page has loaded?

I want to automatically load settings and update some details in the UI without having the user clicking a button.

Thanks jesusmartinoza. Not sure if you or anyone else knows, but whatever Anders Sivesind saw in the older documentation was not apparent to me in the new documentation.

At first I though an <OnUpdate/> tag could be used to trigger loading js code, but no such function name actually exists.

Then I tried adding:

// {config} coming from a .js file loaded earlier
<OnUserEvent Name="finished" Handler="{config}"/>
<PageLoaded>
    <RaiseUserEvent EventName="finished"/>
</PageLoaded>

But this also did not work. Is there not something equivalent to:

// jquery
$(document).ready(function() {
    console.log("Ready!");
});

To execute JS code to configure user stuff you can use it like this:

<App>
  <JavaScript>
    // JavaScript executed on app startup
  </JavaScript>

  <!--- You regular app UI -->
</App>

Or if you want more control over the app, Life Cycle module is for you :slight_smile:

Thanks! Using the <JavaScript> tag is working best for me. I haven’t had any luck with the Lifecycle module when using Fuse Studio / viewport. Works fine on a device, but I didn’t want to have to build out all the time.
