Manipulating Angular and Typescript to utilize the method's parameter value as a JavaScript object's value

I am currently working with Ionic, Angular, and Typescript, attempting to dynamically set the value of a location based on the parameter passed from a method.

Here is the relevant code snippet:

async fileWrite(location) {
    try {
      const result = await Filesystem.writeFile({
        path: `test.txt`,
        data: `This is a test`,
        directory: location,
        encoding: FilesystemEncoding.UTF8
      });
      alert('Wrote file' + result);
    } catch (e) {
      alert('Unable to write file' + e);
    }
  }

As you can see:

directory: location,

The 'location' variable contains the necessary value.

I am passing it as follows:

<ion-button (click)="fileWrite('FilesystemDirectory.Cache')">FileWrite to Cache</ion-button>

However, for some reason, it is not being recognized as a variable.

How can I address this issue?

Answer №1

Give this a shot.

In your Typescript file, insert this line right before the constructor:

directory = FilesystemDirectory;

Then, within your template, add the following:

<ion-button (click)="fileWrite(directory.Cache)">FileWrite to Cache</ion-button>

I hope this information proves useful.
