用Javascript获取经纬度

Question

I am trying to incorporate the user's current longitude and latitude into an iframe url. My code is below.

<script>

var lat = position.coords.latitude;
var lon = position.coords.longitude;

document.write('<iframe src=http://weather.wdtinc.com/imap/imap5/?&INIT_LAT='+lat+'&INIT_LON='+lon+'> </iframe>');
</script>

This just gives me a blank page. Does anyone know what I am doing wrong?

Answer 1

You missed quote in src

    navigator.geolocation.getCurrentPosition(function(position) {
      document.write('<iframe src="http://weather.wdtinc.com/imap/imap5/?&INIT_LAT=' +
        position.coords.latitude+
        '&INIT_LON='+
        position.coords.longitude+'" > </iframe>');
  });
