Calling JavaScript methods from typescript

Question

Currently, I'm trying to use work with the online view of the document and I came across this website.https://rollmyfile.com/.

when I head towards the developer APIs https://rollapp.readme.io/v1.0/docs/rollmyfile-js-api. I find I can read any document by passing the URL. But I'm working on angular 4 which uses typescript so I did call out

so I placed the js code in my index.html

index.html

<script type="text/javascript" src="https://api.rollapp.com/1/js/rollmyfile.js"></script>

now I need to make use of this js file to pass the Url to it something this.

<script type="text/javascript">
    var key = "SeCur3AP1K3y";

    var rollMyFile = new RollMyFile(key);
</script>
rollMyFile.openFileByUrl("https://www.example.com/documentation/overview.docx");

so, I need to make use of .openFileByUrl in my .component.ts

I have referred the path as well in my .component.ts something like this

///<reference path="https://api.rollapp.com/1/js/rollmyfile.js"/>

but still, I'm not able to create an instance of RollMyFile.

I'm getting [ts] Cannot find name 'RollMyFile' error.

Is there something that I'm doing wrong?

you should probably declare your RollMyFile somewhere in the components you need it declare RollMyFile: any. Would be better if you had typings but this should be enough to get it working. — Supamiu

i did it but its throwing me an error Cannot find name 'RollMyFile'. Did you mean the instance member 'this.RollMyFile' — Abhishek Ekaanth

Can you please add the component where you try this call to your question? — Supamiu

Hint: <reference path... doesn't do what you think it does — Aluan Haddad

You need to declare RollMyFile on top in order to use that function in your TS file

 declare const RollMyFile: any;

ngOnInit() {
 console.log("hi");
 var key = "SeCur3AP1K3y";
 var rollMyFile = new RollMyFile(key);
 console.log('rollMyFile',rollMyFile)
}

This console giving me error because of having wrong secret key.

try this in your component :

declare RollMyFile: any;
constructor(private _script: ScriptLoaderService) {}
ngOnInit() {
    this._script.load('body', 'https://api.rollapp.com/1/js/rollmyfile.js')
        .then(result => {
        });
    }
}

and use RollMyFile in your code something like this:

(<any>RollMyFile).somfunction();
