O.T.: variable and Javascript Question


Recommended Posts



i want to run the "function bunload" if variable "closechecker" is 1


i have in Mainform/Script:

function bunload() 

if (closechecker = 1) {dontleave="MountainOffice"; return dontleave;}

onbeforeunload = bunload;



on startup i set in Mainform the closechecker on 1 ...

procedure TMainForm.UniFormCreate(Sender: TObject);
UniSession.AddJS('var closechecker = 1;');...

if user clicks a "Mail-Button" .. then i set closechecker = 0 ... start creating mail .. and set closechecker = 1 

procedure TMainForm.Something to Click(Sender: TObject);
UniSession.AddJS('closechecker = 0;');
UniSession.AddJS('closechecker = 1;');...

but the "function bunload"  is allways "active" ...

can someone finde my mistake ?
