Can't seem to pass JS argument (variable) to Google Map API v3 function

I'm attempting to move a large block 开发者_如何学编程of Google Maps API script off of the page and into an included .js file.

But! In order to do that I've got to tweak the function to accept passed variables.

Here's the start of the script normally...

<script type="text/javascript">
//<![CDATA[
function loadGmap() {
  var map1options = {
    center: new google.maps.LatLng(-12.043333,-77.028333),
    mapTypeId: google.maps.MapTypeId.TERRAIN,
    zoom: 4,
    minZoom: 2,
    streetViewControl: false
  };

and here's me try to pass the first variable (and failing)...

<script type="text/javascript">
//<![CDATA[
function loadGmaps() {
  loadGmap('-12.043333,-77.028333');
}

function loadGmap(coordinates) {
  var map1options = {
    center: new google.maps.LatLng(coordinates),
    mapTypeId: google.maps.MapTypeId.TERRAIN,
    zoom: 4,
    minZoom: 2,
    streetViewControl: false
  };

Ideas? Maybe this shouldn't be a string... or something?

center: new google.maps.LatLng(-12.043333,-77.028333),

There you pass two arguments to LatLng. In your new function, you still need to pass two arguments to LatLng. The easiest way to do this is to accept two arguments to your function:

function loadGmaps() {
    loadGmap(-12.043333,-77.028333);
}

function loadGmap(lat, lng) {
    var map1options = {
        center: new google.maps.LatLng(lat, lng),
        mapTypeId: google.maps.MapTypeId.TERRAIN,
        zoom: 4,
        minZoom: 2,
        streetViewControl: false
    };
}

You need to pass the same arguments... That method accepts 2 arguments: latitude and longitude, not a single string argument.

function loadGmaps() {
    loadGmap(-12.043333, -77.028333);
}

function loadGmap(lat, long) {
    var map1options = {
        center: new google.maps.LatLng(lat, long),
        ...

Change to this line:

center: new google.maps.LatLng(
  parseFloat(coordinates.split(",")[0]), 
  parseFloat(coordinates.split(",")[1])
),   

As of recent you need to CAST the LatLng variables as follows:

buildinglatlng = new google.maps.LatLng(Number(maplatitude), Number(maplongitude));
