How to use and differentiate between the oninput, onchange, and onpropertychange events

The oninput, onchange, and onpropertychange events are all used to detect changes in user input, but there are some differences.

1. The oninput event:

1. Applicable to input and textarea elements.
2. Trigger immediately when user input changes, regardless of whether the content actually changes.
3. For consecutive triggers from multiple inputs, the event will only triggered once.
4. Not compatible with Internet Explorer 8 and below browsers.

1. The onchange event:

1. Applicable to most form elements, such as input, select, and textarea, etc.
2. This is triggered when the element loses focus and its content changes.
3. The event will only be triggered once when an element loses focus in the case of multiple consecutive inputs.
4. Supports all major web browsers.

1. Event for when a property changes:

1. Only applicable for Internet Explorer browser.
2. Triggered when there is a change in the element’s properties, including content, style, and attributes.
3. For multiple consecutive triggering inputs, multiple events will be triggered.
4. It is recommended to use the oninput or onchange events instead in IE9 and above versions.

In summary, the oninput event is the latest standard event that is suitable for most modern browsers, allowing real-time monitoring of changes in user input. The onchange event triggers later, only when the user loses focus. The onpropertychange event is only applicable to IE browsers, which are outdated, so it is recommended to use oninput or onchange events as alternatives.
