should I use encodeuri or encodeuricomponent for encoding urls?

Question

Can anyone tell me should I use encodeURI or encodeURIComponent  for encoding URLs? 

Answer 1

It depends on the usage you are looking for. If you use encodeURI, the input is assumed to be a complete URI. For encodeURIComponent, it encode all with special meaning which can be used with the below components:

var world = "A string with symbols & characters that have special meaning?";

var uri = 'http://example.com/foo?hello=' + encodeURIComponent(world);
