I thought this would be much easier but obviously I missing something.
I have a reference to a javascript file in my html e.g.
<script src="myfile.js?k=123456"></script>
With typescript I want to pull the k query string value and use it when processing in my typescript/javascript. How can I do this?
If you support modern browsers, then you can use URL.searchParams to parse out the k parameter like:
const src = document.body.querySelector('script').src;
const params = (new URL(src)).searchParams;
console.log(params.get('k'))<script src="myfile.js?k=123456"></script>You can use document.querySelector(), or add an id to your script tag, and get the query string value from its src property:
let value = document.querySelectorAll('script')[1].src.split('k=')[1];
let value2 = document.getElementById('script').src.split('k=')[1];
console.log(value, value2);<script id="script" src="myfile.js?k=123456"></script>
