====== getURLvars() ======
wrtc.getURLvars() is a handy way of allowing the request URL control behavior of wrtc_kit.

===== Arguments =====
None.

===== Returns =====
Nothing.

===== Affects =====
Tags in the URL affects wrtc settings:
^ URL tag ^ same as ^ result ^
| audio=no | [[ixnx:wrtc:js:api:wrtc:getaudio|wrtc.getAudio]] = false | do not use mic |
| call=//addr// | [[ixnx:wrtc:js:api:wrtc:adv.callto|wrtc.adv.callTo]] = //addr// | call //addr// after page loaded |
| dtmf=//dtmf// | [[ixnx:wrtc:js:api:wrtc:adv.dialdtmf|wrtc.adv.dialDTMF]] = //dtmf// | dial //dtmf// after page loaded |
| getmedia=no | [[ixnx:wrtc:js:api:wrtc:adv.getmedia|wrtc.adv.getMedia]] = false | access local mic/cam first when making/receiving call |
| getvideo=no | [[ixnx:wrtc:js:api:wrtc:getvideo|wrtc.getVideo]] = false | do not use camera |
| getvideo=yes | [[ixnx:wrtc:js:api:wrtc:getvideo|wrtc.getVideo]] = true | force use of camera |

===== Usage =====
wrtc.getURLvars() is usually called in your [[ixnx:wrtc:js:api:wrtc:init|wrtc.init()]] function.

You can implement the same functionality using multiple [[ixnx:wrtc:js:api:wrtc:geturlvar|getURLvar()]] calls but getURLvars() gives a common URL tag standard for all wrtc_kit implementations.

===== Example =====
  wrtc.init() {
    wrtc.getURLvars();
    ...
  }

Now loading page using URL **company.com/client.htm?getvideo=no;call=john.doe@company.com** will place an audio-only call to john.doe immediately after page has been loaded.
