Thingsboard, access a server side attribute from the widget's javascript

Question

As the title suggests I wanted to know how to access a server side attribute of the thingsboard Map widget.

My goal is to change the color of the polygon based on an attribute but I can't understand how to access this attribute from the javascript snippet in the appropriate area.

Thanks in advance.

Answer 1

you have to select them from Alias panel. By the way you can see the attributes only if you choice a dashboard of type latest values. After you have selected the attribute you can use them from javascript panel:

self.onInit = function(e) {
    console.log("onInit()");
    console.log(self);
}

self.onDataUpdated = function() {
    console.log("start onDataUpdated()");
    console.log(self.ctx.defaultSubscription);
}
