Fires when a property changes on the object.

Note The HTMLTableEvents2::onpropertychange event is only supported in conjunction with the legacy IHTMLElement2::attachEvent IE-only event registration model, which has deprecated since Windows Internet Explorer 9 in favor of the W3C standard "IEventTarget::addEventListener" event model.

Event Property	object.onpropertychange = handler;

Remarks

The HTMLTableEvents2::onpropertychange event fires when properties of an object, IHTMLDocument2::expando, or style sub-object change. To retrieve the name of the changed property, use the event object's IHTMLEventObj2::propertyName property. This property returns a read-only string of the name of the property that has changed. In the case of Cascading Style Sheets (CSS) properties, the property name is prefixed with style. For example, if the CSS property IHTMLStyle::pixelLeft is altered, the value of window.event.propertyName is style.left. By contrast, if the non-CSS property IHTMLFrameBase::name is altered, the value of window.event.propertyName is name.

When the HTMLTableEvents2::onpropertychange event fires, the IHTMLEventObj::srcElement property of the event object is set to the object whose property has changed.

Note Changing the IHTMLElement::innerText or IHTMLElement::innerHTML of child elements will not cause the HTMLTableEvents2::onpropertychange event to fire for the parent element.
