How invoke function by name? Actually I know how invoke function by name, but I can't find needed scope. So now I have to use this[" get " + widgetName] , it is works for _get_publishedBuildsWidget1 but I want make function as private.
So I want invoke by name _get_publishedBuildsWidget2 function
function widgetGeneratorService(commonDashboardService, $filter, buildService, $state) {
var widgetGeneratorServiceFactory = {};
widgetGeneratorServiceFactory._get_publishedBuildsWidget1 = function (widget) {
widget.name = "Test",
return widget;
}
var _get_publishedBuildsWidget2 = function(widget){
widget.name = "Test",
return widget;
}
widgetGeneratorServiceFactory.getDefaultWidget = function (widgetName) {
var defaultWidget = {};
//TODO rewrite!!!
var fnGenerateWidget = this["_get_" + widgetName];
if (typeof fnGenerateWidget === 'function') {
return fnGenerateWidget(defaultWidget);
}
return defaultWidget;
}
return widgetGeneratorServiceFactory;
};
You can't invoke private functions via a string variable except via eval()
, and that's generally a bad idea.
However you can trivially create a private object that contains references to those private methods, and then index into that to get the desired function:
function widgetGeneratorService(...) {
var methods = {
func1: func1
...
};
methods['func1']();
}
