[OpenLayers-Users] Formatting output text

[JK Chen]

Where should the new code be inserted to?

Thanks.

You could override the toString method of LonLat:

OpenLayers.LonLat.prototype.toString = function() {
    return ("N " + this.lat.toFixed() + ", E " + this.lon.toFixed());
}

Best regards,
Bart

How do I go about reformatting the text output from a coordinate
variable?

In other words, I have output from a mouse position which has been
transformed into different coordinate systems, and then gets displayed
on the screen.

It now looks something like this:

lon=414614.58552010887,lat=164066.82345258445

In reality, the values are x and y coords in feet or meters, not lonlat
coords. I'd like them to look like this:

N 164066, E 414614

Note the truncation of the digits and switching of the x, y (which is
customary in my field). Not being a JS expert, I can't figure out how to
get at the variable to massage the format prior to display on the
screen.

Here's the code leading up to the display (inside of a mousemove
function):

mousepos = map.getLonLatFromViewPortPx(e);
var NAD83ft_values = mousepos.clone();   // done several times for
different coord translations

NAD83ft_values.transform(WGS84_google_mercator, NAD83ft_proj);
document.getElementById("NAD83feet").innerHTML = NAD83ft_values;


It's unpacking NAD83ft_values that has me thrown. Any help?
