inputIcon[i].addEventListener('mousedown', function () {

});
inputIcon[i].addEventListener('mouseup', function () {
var element = this;
setTimeout(function () {
element.classList.remove('e-input-btn-ripple');
}, 500);
});
}
import { Input, InputObject } from '@syncfusion/ej2-inputs';
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
let inputObj: InputObject;
let element: HTMLInputElement = <HTMLInputElement>document.createElement('input');
document.getElementById('input-container').appendChild(element);
Input.createInput({
element: element,
floatLabelType: "Auto",
properties:{
placeholder:'Enter Name'
}
});
let element2: HTMLInputElement = <HTMLInputElement>document.createElement('input');
document.getElementById('input-container-01').appendChild(element2);
Input.createInput({
element: element2,
floatLabelType: "Always",
properties:{
placeholder:'Enter Name'

});
let element3: HTMLInputElement = <HTMLInputElement>document.createElement('input');
document.getElementById('input-container-02').appendChild(element3);
Input.createInput({
element: element3,
floatLabelType: "Never",
properties:{
