How I get my location in javascript by phonegap and calculate the distance between my location and my destination.

not wikitude related answer but it is easy job, you get location with phonegap geolocation plugin:

http://docs.phonegap.com/en/3.0.0/cordova_geolocation_geolocation.md.html#Geolocation

you calculate the distance between 2 locations can be done by converting them in metric coordinate system from lat,lon. You can use google's (900913)

then calculating the distance between 2 points is:

point1(x1,y1) , point2(x2,y2)

distance=sqrt((x1-x2)^2+(y1-y2)^2)
