    In plain JavaScript you can do this:

    const show = () => {
  const sel = document.getElementById("Example"); // or this if only called onchange
  let value = sel.options[sel.selectedIndex].value; // or just sel.value
  let text = sel.options[sel.selectedIndex].text;
  console.log(value, text);
}

window.addEventListener("load", () => { // on load 
  document.getElementById("Example").addEventListener("change",show); // show on change
  show(); // show onload
});
    <select id="Example">
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

    jQuery:

    $(function() { // on load
  var $sel = $("#Example");
  $sel.on("change",function() {
    var value = $(this).val();
    var text = $("option:selected", this).text();
    console.log(value,text)
  }).trigger("change"); // initial call
});
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="Example">
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

    Here the selected text and value is getting using jquery when page load 

    $(document).ready(function () {
var ddlText = $("#ddlChar option:selected").text();
var ddlValue = $("#ddlChar option:selected").val();
});
