, and caused by
user's selecting a list of predefined values (a.k.a., items).
It is always false if it is caused by the onChange
event.
Currently, only combobox might set it to true for the onChanging
event. It is useful when you implement autocomplete.
To have better response, you usually don't filter out unmatched items
if this method returns true. In other words, you simply ignore
the onChanging
event if this method return true, when
implementing autocomplete.
public int getStart()
Note: In IE browser, we cannot get the position of cursor because onblur
event of Javascript is always fired before onChange
is fired.
To get the position of cursor, onChanging
event is suggested
since onblur event of Javascript will not be fired.
