How to convert signs in url/text to hex characters? (converting = to %3D)

Question

With the script I'm making, jquery is getting vars from url parameter. The value that its getting is an url so if its something like

http://localhost/index.html?url=http://www.example.com/index.php?something=some

it reads:

url = http://www.example.com/index.php?something

If its like

http://localhost/index.html?url=http://www.example.com/index.php?something%3Dsome

it reads:

url = http://www.example.com/index.php?something%3Dsome

which would register as a valid url. my question is how can I search for = sign in the url variable and replace it with hex %3D with jquery or javascript?

Answer 1

Use the (built-in) encodeURIComponent() function:

url = 'http://localhost/index.html?url=' +
    encodeURIComponent('http://www.example.com/index.php?something=some');

Answer 2

Are you looking for encodeURIComponent and decodeURIComponent ?
