Can't append <script> element

I've seen issues where some browsers don't respect some changes when you do them directly (by which I mean creating the HTML from text like you're trying with the script tag), but when you do them with built-in commands things go better. Try this:

var script = document.createElement( 'script' );
script.type = 'text/javascript';
script.src = url;
$("#someElement").append( script );

From: JSON for jQuery

It is possible to dynamically load a JavaScript file using the jQuery function getScript

$.getScript('http://www.whatever.com/shareprice/shareprice.js', function() {
  Display.sharePrice();
});

Now the external script will be called, and if it cannot be loaded it will gracefully degrade.

What do you mean "not working"?

jQuery detects that you're trying to create a SCRIPT element and will automatically run the contents of the element within the global context. Are you telling me that this doesn't work for you? -

$('#someElement').append('<script>alert("WORKING");</script>');

Edit: If you're not seeing the SCRIPT element in the DOM (in Firebug for example) after you run the command that's because jQuery, like I said, will run the code and then will delete the SCRIPT element - I believe that SCRIPT elements are always appended to the body... but anyway - placement has absolutely no bearing on code execution in this situation.

<script>
    ...
    ...jQuery("<script></script>")...
    ...
</script>

The </script> within the string literal terminates the entire script, to avoid that "</scr" + "ipt>" can be used instead.

I tried this one and works fine. Just replace the < symbol with that \x3C.

// With Variable
var code = "\x3Cscript>SomeCode\x3C/script>";
$("#someElement").append(code);

or

//Without Variable
$("#someElement").append("\x3Cscript>SomeCode\x3C/script>");

You can test the code here.

I wrote an npm package that lets you take an HTML string, including script tags and append it to a container while executing the scripts

Example:

import appendHtml from 'appendhtml';

const html = '<p>Hello</p><script src="some_js_file.js"></script>'; 
const container = document.getElementById('some-div');

await appendHtml(html, container);

// appendHtml returns a Promise, some_js_file.js is now loaded and executed (note the await)
