How to get access to GeoJSON FeatureCollection objects in JavaScript
<p>I have a URL linking to a JSON file of a GeoJSON FeatureCollection object.</p>

<p><code>{"type": "FeatureCollection", "features": [{...}, {...}, ...]}</code></p>

<p>I insert an attribute "properties" into this FeatureCollection object and assign a value "myFeatureCollection" to the key "name". </p>

<p><code>{"type": "FeatureCollection", "features": [{...}, {...}, ...], "properties": {"name": "myFeatureCollection"}}</code></p>

<p>Can I get access to the value "myFeatureCollection" from the outside in JavaScript?</p>

<p>In a word, I am seeking a method to achieve the following objective (pseudo-code):</p>

<p><code>var fc = jsonRead("myJsonUrl");</code></p>

<p><code>var fcName = fc.properties.name;</code></p>
