Hi @muchhar_bharat, is this what you are looking for?

import streamlit as st
import streamlit.components.v1 as components

a = """
<script> function changeText(value) { document.getElementById('my_para').innerHTML = "You clicked me using button titled " + value; } </script>
<input type="button" value="Click Me!" id="my_btn" onclick="changeText(this.value);"/>
<p id="my_para">Hello word</p>
"""
components.html(a,height=800,width=1200)

Cheers
