<input type="text" onchange="handler" ... > text.onchange
The onchange property of a Text element refers to an event handler function that is invoked when the user changes the value in the input field and then "commits" those changes by moving keyboard focus (i.e., by clicking the mouse elsewhere or pressing
Tab or
Return ).
Note that the onchange event handler is
not invoked when the value property of a Text object is set by JavaScript. Also note that this handler is intended to process a complete change to the input value, and therefore it is not invoked on a keystroke-by-keystroke basis. See the HTMLElement.onkeypress reference page for information on receiving notification of every key press event.
See Input.onchange for complete details about the onchange event handler.
