loadWithXhr

loadWithXhr(options) → Promise.<Object>|undefined

Asynchronously loads the given URL. Returns a promise that will resolve to the result 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.
Name Type Description
options Object Object with the following properties:
Name Type Default Description
url String The URL of the data.
responseType String optional The type of response. This controls the type of item returned.
method String 'GET' optional The HTTP method to use.
data String optional The data to send with the request, if any.
headers Object optional HTTP headers to send with the request, if any.
overrideMimeType String optional Overrides the MIME type returned by the server.
request Request optional The request object.
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.
Example:
// Load a single URL asynchronously. In real code, you should use loadBlob instead.
Cesium.loadWithXhr({
    url : 'some/url',
    responseType : 'blob'
}).then(function(blob) {
    // use the data
}).otherwise(function(error) {
    // an error occurred
});
