Jsonpropertychange input box event get attribute _ form special effect

Onpropertychange is mainly used to obtain user modifications and other events in real time. When the attribute of an HTML element changes, it can be captured through onpropertychange. For example, when the value Attribute of the <input name = "text1" id = "text1"/> object is modified by the script on the page, onchange cannot be captured, but onpropertychange can be captured.

The specific understanding is: onpropertychange can capture changes in the attribute value in time, while onchange can only activate this event by executing some operations with the mouse when the attribute value changes!

However, onpropertychange is only supported by IE. How can this problem be solved in FireFox? The event oninput of firefox has the same effect as the onproperchange of IE.
