Compatible with Firefox and IE's onpropertychange event oninput_form effects

When entering data in the text box, you can use onkeyup to detect events when the keyboard is pressed and released. onpropertychange can capture every change, and onchange needs to execute an event before it can be captured. But sometimes we input data by pasting instead of keyboard input, which requires real-time detection of changes in the text box state.
onpropertychange is not supported by firefox. If you want to use it normally under firefox, you need to use the oninput attribute and addEventListener to register the event.

<div id="msg"></div> <input id="txt" value="">
[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute

]

Example:

Copy code

The code is as follows:

< div>oninput test
