How to Append in javascript?


Question

I need to use childappend or jquery append() to append some tag stuff into the document. From what I can tell, this is getting stripped out. Anyone know how to do it?

Accepted Answer

Try this:

var s = document.createElement("script");
s.type = "text/javascript";
s.src = "http://somedomain.com/somescript";
$("head").append(s);

Note that the script will load and you can access the variables inside it, but you wouldn't see the actual <script> tag in the DOM.

$('<script>alert("hi");</' + 'script>').appendTo(document.body);

If you need to append a script so that it's parsed you could do as google does for his +1 button

  (function() {
    var po = document.createElement('script');
    po.type = 'text/javascript';
    po.async = true;
    po.src = 'link to your script here';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(po, s);
  })();

This worked for me..

<script>
    $('head').append("<script>your script content here<\/script>");
</script>

Note that the "/" of the inner </script> has been escaped to be "<\/script>". If it is not, it actually closes the outer <script> tag.

The script added wont be visible but will get executed. Hope that helps.

$('your_document_selector').text('<script></script>')

.text() makes it possible to append script tags with it being rendered as HTML.

OR

$('your_document_selector').append('&lt;script&gt;&lt;/script&gt;')
