loadJson

loadJson(urlOrResource, headers, request) → Promise.<Object>|undefined
Core/loadJson.js 47

Asynchronously loads the given URL as JSON. Returns a promise that will resolve to a JSON object once loaded, or reject if the URL failed to load. The data is loaded using XMLHttpRequest, which means that in order to make requests to another origin, the server must have Cross-Origin Resource Sharing (CORS) headers enabled. This function adds 'Accept: application/json,*/*;q=0.01' to the request headers, if not already specified.
Name Type Description
urlOrResource Resource | String The URL to request.
headers Object optional HTTP headers to send with the request. 'Accept: application/json,*/*;q=0.01' is added to the request headers automatically if not specified.
request Request optional The request object. Intended for internal use only.
Returns:
a promise that will resolve to the requested data when loaded. Returns undefined if request.throttle is true and the request does not have high enough priority.
Deprecated: true
Example:
Cesium.loadJson('http://someUrl.com/someJson.txt').then(function(jsonData) {
    // Do something with the JSON object
}).otherwise(function(error) {
    // an error occurred
});
