javascript - Google Maps API - Map.data scope issue -

-

I am trying to add a geo-layer layer in Google Maps (v3) by doing the following:

< Pre> imageActive = {url: "images / target_red.png", original: new google.maps.Point (0,0), anchor: new google.maps.Point (11, 11), // // active Marker image JQuery.getJSON ('home / gcpts / geojson.php', function (data) {points = map.data.addGeoJson (data); console.log (digits); // this works}}; Map.data.setStyle ({clickable: true, dragable: incorrect,}); Map.data.addListener ('click', function) {setActiveImage (event);}) Function setActive image (event) {for (var i = 0; i & lt; points.length; i ++) {/ Can not read / "length" of the undefined points [i] .revertStyles (); } Map.data.overrideStyle (event.feature, {icon: imageActive,}); }

However, when I try to repeat through the "numeral" variable, I do not see "see". I get mainly undefined, or if I try to call the number of points (points.length), then it does not exist.

If I do console.log in jQuery function, then I can see all the attributes inside the variable. If I keep it outside, then I can not see it. Is there something that I'm missing about the scope?

It is my hope that I can set up a "click" event and use the event. Feature override style When a different feature is clicked, the style is removed from other GeoJon features and overrides the new clicked feature.

It seems that it should work fine, but I do not know this

(Besides, I am using jQuery in the "no conflicts" mode. All your variables are scoped globally because you have var

point variable and overwrites your assume that your code is already in some type Hnkshn (such as wrapped in a jQuery ready handler), you can solve your problem by only using var . I will add the code of this line before calling getJSON () : 

  var number = [];
