select event listener javascript code example

Example 1: js html textbox on change

<!-- 
	You can use any of the following:
	onkeydown, onkeyup or onchange
 -->

<input type="text" onkeydown="keydownFunction()" 
onkeyup="keyupFunction()" onchange="changeFunction()">

Example 2: where is select value in javascript event object

let handleSelect = (e) => { // e === this
    console.log(event.target.value) // event !== this 
}

Example 3: on change event html not working

onchange is only triggered when the control is blurred. Try onkeypress instead.
