Return value and get it from window.angularComponentRef.zone.run

Question

I know that how to call angular functions inside the component via a static file according to the below link :

How to expose angular 2 methods publicly?

It says use zone in angular as I mention below :

 window.angularComponentRef.zone.run(() => {
 window.angularComponentRef.component.calledFromOutsideToUploadChatImageandGetURL("test");
})

my angular function is :

calledFromOutsideToUploadChatImageandGetURL(chatImage64Bit: string) {
    this.doctorService.UploadChatImageandGetURL(chatImage64Bit).subscribe(
        data => {

            console.log(chatImage64Bit);
            //blablabla


    );

    return "RESULT";
}

But I want to get returned value ("RESULT") from my angular function(calledFromOutsideToUploadChatImageandGetURL) but I cant. I just could call it! any idea ?

Answer 1

After a little bit tries I found out it could be done simply by the following code:

 var retuenValue = window.angularComponentRef.zone.run(function map() {
 var  xx =  window.angularComponentRef.component.calledFromOutsideToUploadChatImageandGetURL("test");
                return xx;
            });
 console.log(retuenValue);
