Executing JavaScript functions within TypeScript

Executing JavaScript functions within TypeScript

Currently, I am working on integrating the online document viewer into my project and stumbled upon a website called .

As I explored the developer APIs at , I discovered that I could access any document by providing its URL. However, I am using Angular 4 with Typescript so I encountered some challenges.

To tackle this issue, I included the JavaScript code in my index.html file:

index.html

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

Next, I needed to utilize this JS file to pass the URL as follows:

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

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

Subsequently, I attempted to use .openFileByUrl in my .component.ts file.

I also referenced the path in my .component.ts like this:

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

However, I am still encountering an issue where I cannot create an instance of RollMyFile.

The error message states:

[ts] Cannot find name 'RollMyFile'

.

Could you please advise on what might be going wrong in this scenario?

Answer №1

To successfully utilize the RollMyFile function in your TS file, it is necessary to declare it at the beginning.

 declare const RollMyFile: any;

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

An error is occurring in the console due to an incorrect secret key being used.

Give this a shot 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 => {
        });
    }
}

Then, utilize RollMyFile in your code like this:

(<any>RollMyFile).somfunction();
