Quick Reference
The JavaScript decodeURIComponent() method decodes (i.e., removes %20 and replaces it with a space) a URI component.
<!-- html element to place output -->
<p id="my_output"></p>// variables
let my_uri = 'https://www.1SMARTchicken.com/my site.php?band=Mötley Crüe';
let encoded = encodeURIComponent(my_uri);
let decoded = decodeURIComponent(encoded);
// output to the HTML element
document.getElementById('my_output').innerHTML = 'Encoded URI:<br>' + encoded + '<br><br>' + 'Decoded URI:<br>' + decoded;Output
Encoded URI:
https%3A%2F%2Fwww.1SMARTchicken.com%2Fmy%20site.php%3Fband%3DM%C3%B6tley%20Cr%C3%BCe
Decoded URI:
https://www.1SMARTchicken.com/my site.php?band=Mötley CrüeSyntax
decodeURIComponent(uri)JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
