Load inline JS after page load

I want to load an inline JavaScript after the page has fully loaded. The reason is, that the scripts loads an external JS file which I don’t want to block the rendering of the page.

This is the whole code:

<script type="text/javascript">
(function () {
var _tsid = 'XXXX';
_tsConfig = {
  'yOffset': '0', // offset from page bottom
  'variant': 'custom_reviews', // default, reviews, custom, custom_reviews
  'customElementId': 'MyCustomTrustbadge', // required for variants custom and custom_reviews
  'trustcardDirection': 'bottomLeft', // for custom variants: topRight, topLeft, bottomRight, bottomLeft
  'customBadgeWidth': '', // for custom variants: 40 - 90 (in pixels)
  'customBadgeHeight': '', // for custom variants: 40 - 90 (in pixels)
  'disableResponsive': 'false', // deactivate responsive behaviour
  'disableTrustbadge': 'false' // deactivate trustbadge
};
var _ts = document.createElement('script');
_ts.type = 'text/javascript';
_ts.charset = 'utf-8';
_ts.async = true;
_ts.src = '//widgets.trustedshops.com/js/' + _tsid + '.js';
var __ts = document.getElementsByTagName('script')[0];
__ts.parentNode.insertBefore(_ts, __ts);
})();
</script>

I know that I could maybe use $(document).ready. But I don’t know how.

Adding the defer attribute to the script element will defer execution until the DOM is ready while allowing the script to be downloaded in parallel.
