c# - What is the correct way to encode querystring in javascript and decode properly on asp.net-mvc serverside? -

i had asp.net-mvc site , have issue had "&" in query string building javascript , using ajax server. this:

 www.mysite.com/mycontroller/load?tag=m&ms

when passed server using ajax, showing

tag="m"

so, in javascript code, changed code this:

  "load?tag=" + tag;

to:

  "load?tag=" + encodeuricomponent(tag);

and fixed issue. server code looks this

 public actionresult load(projectparams projectparams)  {       //go stuff  }

where projectparams looks this:

public class projectparams {     public string tag {get;set;} }

so great until realized making change on javascript side, had knockon effect. ran issue if have spaces in tag name, shows on server as:

  my%20tag%20name

instead of:

  tag name

what correct way encode on javascript side url querystring , ensure shows on serverside controller action

you can decode

server.urldecode()

and on setter
