Call a JS function from another QML

I have 2 QMLs, the 1st one has the JS Function, I want to call the JS Function in the 2nd QML.

I believe this can be done but can't find any resources how to do this. Any suggestions please?

Re: Call a JS function from another QML

[ Edited ]

if your js function is not in main .qml this method should help out (if it is, move it to 2nd qml)

//reasoning for moving is the only way i have found to access something from main qml in another is to use qsettings, but that doesn't quite work out for functions.

 

1st qml (with function)

Container {
   id: root
   property alias thisRoot: root

   function myFunction(){
       //do stuff
   }
}

main.qml (or 2nd qml)

Button {
  onClicked: {
     thisRoot.myFunction();
  }

Re: Call a JS function from another QML

It depends on the relationship of the QML files as well as what the function achieves.
If the function is just some computation function that is independent of the QML component it is declared in, you can extract it to a .js file.
If the 2nd QML is included in the 1st on (so a custom component display), then you can just call the function similar to what slashkyle proposed.
