Hello,

Is there sample code available that references this HOOPS Advanced Publish API;

CHECK\_RET( **A3DPDF3DAnnotSetActionJavascript** (pPage, p3DAnnot,kA3DPDFEventFieldMouseDown, zoomLevelJavaScriptCode));

I was trying to figure out why my JavaScript wasn’t working, and as a simple test, I am calling this API with a ‘Hello World’ script, and it will still not log to the console when there’s a mouse down event on the p3DAnnot.

Thanks,  
Justin

Hello Justin,  
I noticed this issue when using `kA3DPDFEventFieldMouseDown` . I will check with the engineering team and get back to you soon.  
However, if you need to verify that your Javascript is working correctly, I recommend setting `kA3DPDFEventPageVisible` to check the result.

Hello Justin,

After further analysis by our engineer, this is a restriction of Acrobat. HOOPS does create the JavaScript correctly, but Adobe does not execute the mouse events.

```auto
std::string sJS = "console.println(\"kA3DPDFEventFieldMouseUp\");\n";
A3DPDF3DAnnotSetActionJavascript(pPage, p3DAnnot, kA3DPDFEventFieldMouseUp, sJS.c_str());

```
