Encode URL in JavaScript?

How do you safely encode a URL using JavaScript such that it can be put into a GET string?

var myUrl = "http://example.com/index.html?param=1&anotherParam=2";
var myOtherUrl = "http://example.com/index.html?url=" + myUrl;


I assume that you need to encode the
myUrl
variable on that second line?

Answer

Check out the built-in function encodeURIComponent(str) and encodeURI(str).
In your case, this should work:

var myOtherUrl = 
       "http://example.com/index.html?url=" + encodeURIComponent(myUrl);
