JavaScript micro-Position function implementation method _javascript skills

Share how the micro-letters are positioned:

This article mainly explains how to use the micro-letter positioning, how to convert the latitude and longitude of the location to the corresponding latitude and longitude of Baidu map, as well as deal with positioning failure, cancellation and error when the default approach.

       Longitude, floating-point number, range 180 ~-180. * Below is to get the true latitude and longitude to convert to the corresponding Baidu latitude and longitude, because the use of the latitude and longitude of Baidu map to query data, the database is also Baidu's latitude and longitude * *///Create a Baidu map point var customerpoint = new BMAP.P

  var convertor = new Bmap.convertor ();     var Pointarr = [];//Create an array pointarr.push (customerpoint);/Put the point in Convertor.translate (Pointarr, 1, 5, INITMAP);
         Convert coordinate function initmap (data) {if (Data.status = 0) {//convert success var point = data.points[0];// var LNG = point.lng;//Gets the converted longitude var lat = point.lat;//Gets the converted latitude todofunction (LNG, LAT);//Pass the longitude and latitude to the

       R LNG = 120.141375;
       var lat = 30.257806;
     Todofunction (LNG, LAT);//Pass the latitude and longitude to the function to be used}}); Location Error Wx.error (function () {//The following two lines are the default positioning to the West lake latitude and longitude var lng = 120.141375;
      var lat = 30.257806;

    Todofunction (LNG, LAT);//Pass the latitude and longitude to the function to be used});
   });
 }
  });
 }

The above code, if you can locate to the true latitude and longitude, and then converted to Baidu map corresponding latitude and longitude, if the location failed or click to cancel or error, the default positioning to the West lake latitude and longitude.

The above is the entire content of this article, I hope to help you learn, but also hope that we support the cloud habitat community.
