how to passing a javascript object used by webengine.executeScript()

Question

I'm a beginner of javafx. this is my function of javascript in my html file

function setMap(mapExtent) {
    if (mapExtent) {
        var args = mapExtent.split(",");
        if (args.length >= 4) {
            frx = parseFloat(args[0]);
            fry = parseFloat(args[1]);
            frzoom = parseInt(args[2]);
            frMapType = args[3];
            if (pMap) {
                pMap.SetMap(mapExtent);
            }
        }
    }

}

I know how to invoke it in C#, like this:

        public void setMap(string sExtend)
        {
            object[] objArray = new object[1];
            objArray[0] = sExtend;
            try
            {
                this.Document.InvokeScript("setMap", objArray);
            }
            catch { }
        }

this javascript function need pass a parameter(a javascript object), but in the API document of JAVAFX8, the parameter of method webengine.executeScript(String script) is a String type only. How to use webengine.executeScript() invoke the setMap(string sExtend)

Get the window object

JSObject jsObject = (JSObject) webEngine.executeScript("window");

then try to call

jsObject.call("setMap", sExtend);

what is the window object? if there has a JS function named "test()" without any parameter, I get window object and write the code like this jsObject.call("test", null);

@RanQilin, window is a global object described as the standard JS Window object. By calling webEngine.executeScript("window") you get it as wrapped into JSObject. And if the setMap() function defined globally, you can invoke jsObject.call("setMap", sExtend);
