How can I check if a value is changed on blur event?

Question

Basically I need to check if the value is changed in a textbox on the \'blur\' event so that if the value is not changed, I want to cancel the blur event.

If it possible

Answer 1

Within the onblur event, you can compare the value against the defaultValue to determine whether a change happened:

The defaultValue will contain the initial value of the object, whereas the value will contain the current value of the object after a change has been made.
