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)

Answer 1

Get the window object

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

then try to call

jsObject.call("setMap", sExtend);
