Onpropertychange is used in Javascript development. The oninput event solves the problem of onchange events.

When onchange is used in the text box input box, there is an obvious deficiency. The event will not be triggered with the text input, but will be triggered when the text box loses the focus (onblur). That is, there is no instant!

In IE, onpropertychange can be used to replace the onchange event. This event can be triggered immediately when there is any change in the text box.

In this way, the problem is solved.

What about other browsers? onpropertychange is the patent of IE. The next step is the oninput event.

However, oninput has a strange problem. You must use addeventlistener to bind the event. Otherwise, the event is invalid.

Okay. The following is a demo. it's okay for mainstream browsers:
