Question

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 1

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);
