如何从单独的文件中调用经/纬

Question

I have a v3api google map that includes optional map polygons the user can choose to display or not.

To display the shapes in the old api I would have javascript code like so:

function rmx_bounds(){
var myShapeCoords = [
new google.maps.LatLng(48.2767,-81.728),
new google.maps.LatLng(48.2786,-80.811),
new google.maps.LatLng(48.7104,-81.727),
new google.maps.LatLng(48.2767,-81.728)
];

var myShape;
myShape = new google.maps.Polygon({
paths: myShapeCoords,
strokeColor: "##f33f00",
strokeOpacity: 1,
strokeWeight: 3,
fillColor: "#9900CC",
fillOpacity: 0.2
});

myShape.setMap(map);
}

However 'myShape' can have hundreds of coordinates and there can be dozens of shapes

rather than stuff my file with thousands of lines, can i somehow put them in a separate file and call it from the function?

Answer 1

您可以将myShapeCoords放在单独的JavaScript文件中，并将其作为<script src="myCoordinates.js" type="text/javascript">

Answer 2

You can put the data to a file in JSON format, and load the file on demand. To process the JSON file you may use straightforward (but unsafe sometimes) approach:

var myObject = eval('(' + myJSONtext + ')');

Or use jQuery, or use any JSON library.
