When we paste data in input field, we can not fetch data from input field, it's always show blank;
function myFunction() {
console.log(document.getElementById("inpt").innerText);
document.getElementById("demo").innerHTML = document.getElementById("inpt").innerText;
}
<input id="inpt" type="text" onpaste="myFunction()" value="Try to paste something in here" size="40">
<p id="demo"></p>
