Question

I am checking if jQuery is included in the document. If not I want create an element after the closing body tag.

<script type="text/javascript">
if( !(typeof jQuery === 'function') ){
    var script = document.createElement('script');
    script.src = 'https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js';
    script.type = 'text/javascript';
    var head = document.getElementsByTagName("head")[0];
    head.appendChild(script);
}
</script>

If I do this with the body tag it appends it to the top. I wanna either append it to the end of the body tag or right after closing it.

Please help.

Answer 1

Use document.body.appendChild(). It will append the element at the end of the body tag.

By the way, jAndy is right, there is little need to add a javascript file dynamically at the end of the body.
