PONeed JavaScript Geolocation and General JavaScript Assistance

copied!<p>I am "attempting" to use JavaScript's geolocation functions, but I am having issues with, I assume, the way JavaScript works. I have found many examples on how to use the geolocation functions and they all, basically, look like this:</p> <pre><code>navigator.geolocation.getCurrentPosition(function(position){alert("Your Coordinates:\nLatitude: " + position.coords.latitude + "\nLongitude: " + position.coords.longitude);}); </code></pre> <p>The above code works, but I am trying to do is something like this:</p> <pre><code>function geoMe(){ var position = navigator.geolocation.getCurrentPosition(); var geoLocationDiv = document.getElementById('geoLocationDiv'); var latitude = position.coords.latitude; var longitude = position.coords.longitude; geoLocationDiv.innerHTML = latitude + "," + longitude; } </code></pre> <p>As you can probably guess, it isn't working. I have never been good at interpreting code that is all "jammed" together like the example, so I am VERY confused.</p> <p>In looking at the example code, it looks like there is a function called "getCurrentPosition". Now, here is where I get lost. It looks like there is a function being passed in as a parameter to getCurrentPosition that has [as a parameter] a parameter called "position". Where did the "position" parameter come from??? I have seen where a function (without an actual function name) is used as a parameter, but it is REALLY confusing to me. Typically, I do something like:</p> <pre><code>function functionName(parameter1, parameter2, parameterN){ function body } </code></pre> <p>I know it is supposed to be advanced to do stuff like this, but I am a simple man, and I like my code simple, and I like my functions to have names.</p> <p>So, can anybody out there help me with getting this GeoLocation stuff to work the way I want it to work? And, maybe along the way, explain this bizarre method of JavaScript functions?</p> <p>Thank you, and have a great day. :-)</p>
