ExtJS Hack: How To Get Selected Index of ExtJS ComboBox

ExtJS ComboBox doesn’t advertise, in its documentation, any way to get the selected index of a ComboBox. Looking at the code I realized we can use the undocumented property selectedIndex. However there is a catch.

ComboBox.reset() doesn’t set the selectedIndex to -1, which it should. So whenever you use selectedIndex, remember to reset it manually after reset(). Otherwise it will return stale value.
