Starting from 25.2, it is possible to run JavaScript code directly within the currently loaded Web Resource.
This enables more specialized use cases—for example, you can trigger animations directly from a cue or a keyframe.

API Command

The command for this is: null executeJavaScriptOnCurrentWebResource(string script)  , this needs to be used on a Layer basis.

Limitations

It's not possible to synchronize animations across multiple instances of the Browser Resource.
This means that in a multi-client setup—where the Web Browser Resource is used across multiple servers—synchronization cannot be guaranteed.

Example

In this example, we use a Web page that already includes the code for the Animations, we just trigger the function itself.

1. First we create a Web Browser Resources, assign the Page to load and put it in the Timeline.
2. Create a NewModule and a New Action. Expanding Your Modules → Expanding Your Actions 
3. Use the API call executeJavaScriptOnCurrentWebResource to trigger the in the HTML stored animation: 
   Pixera.Timelines.Layer.getInst('Timeline 1.Layer 1').executeJavaScriptOnCurrentWebResource("startAnim()") 
4. Create a Cue to trigger the Control Action Cue Network Command (pixc)

Use Cases

Reload

A common scenario is refreshing the browser window without unloading and re‑loading the entire container.
In plain JavaScript you can do this with: 

location.reload();

Calling location.reload() refreshes the page exactly as if you had pressed F5 in your browser. This is handy when a Web Resource needs to update text or other dynamic values during playout, but you want to avoid a full container reset.

Button Press

With this, it is possible to press buttons without the use of a Mouse.

// If the button has an ID
document.getElementById('myButton').click();

// If the button has a class
document.querySelector('.myButton').click();

In the Example provided, the Button has neither class nor id, but it can also be done like this:

local js_code = [[
    document.querySelector('button[onclick="startAnim()"]').click();
]]
Pixera.Timelines.Layer.getInst('Timeline 1.Layer 1').executeJavaScriptOnCurrentWebResource(js_code)
