-
@Diracsbracket
I did one. I changed my function. But here's another problem it work for only one qml file and if we call it from another qml file counter is Zero.function changeColor(rectId, param1) { if( typeof changeColor.counter == 'undefined' ) { changeColor.counter = 0; } changeColor.counter++ }@behruz-montazeri

Where can i declare a javascript global variable ?In a javascript file. Otherwise create a property at a top-level QML object, e.g. your main window, which exists for the duration of your app.

I guess creating property make seance in my situation. making a Javascript file variable doesn't keep track of increasing despite the several calls from different QML files. -

That's usually the best way indeed.
