How to load CZML data from file to variable

CesiumJS
1

I have a .czml file and I would like to load the content and being able to store it into a variable: the goal is to replicate the "CZML Billboard and Label" tutorial where the content czml variable is loaded from file.

/*var czml = [{
    "id" : "document",
    "name" : "Basic CZML billboard and label",
    "version" : "1.0"
}, {
    "id" : "some-unique-id",
    "name" : "AGI",
    "description" : "<p><a href='http://www.agi.com' target='_blank'>Analytical Graphics, Inc.</a> (AGI) founded Cesium.</p>",
    "billboard" : {
        "image" : "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAACvSURBVDhPrZDRDcMgDAU9GqN0lIzijw6SUbJJygUeNQgSqepJTyHG91LVVpwDdfxM3T9TSl1EXZvDwii471fivK73cBFFQNTT/d2KoGpfGOpSIkhUpgUMxq9DFEsWv4IXhlyCnhBFnZcFEEuYqbiUlNwWgMTdrZ3JbQFoEVG53rd8ztG9aPJMnBUQf/VFraBJeWnLS0RfjbKyLJA8FkT5seDYS1Qwyv8t0B/5C2ZmH2/eTGNNBgMmAAAAAElFTkSuQmCC",
        "scale" : 1.5
    },
    "label" : {
        "fillColor" : {
            "rgba" : [255, 255, 255, 255]
        },
        "font" : "12pt Lucida Console",
        "horizontalOrigin" : "LEFT",
        "pixelOffset" : {
            "cartesian2" : [8, 0]
        },
        "style" : "FILL",
        "text" : "AGI",
        "showBackground" : true,
        "backgroundColor" : {
            "rgba" : [112, 89, 57, 200]
        }
    },
    "position" : {
        "cartesian":[
            1216361.4096947117, -4736253.175342511, 4081267.4865667094
        ]
    }
}];*/

var czml = function_to_load_czml_data('file.czml') // What should I write here???

var viewer = new Cesium.Viewer('cesiumContainer');
viewer.dataSources.add(Cesium.CzmlDataSource.load(czml));

Thanks for the attention!

Hi there,

Although all our examples have the czml as a string variable, like with other datasource types, it can be loaded from a path. See here: https://cesiumjs.org/Cesium/Build/Documentation/CzmlDataSource.html#.load

Hope that helps,
