Retrieving values from objects using Typescript

I am facing an issue while trying to retrieve a value from an object. The key I need to use belongs to another object.

Screenshot 1

Screenshot 2

However, when working with Typescript, I encounter the following error message.

Error in Visual Studio

Is there a way to access the value without having to change the object type?

public data: string | {};

Answer №1

Try using the typeof function - it will either give you a result of string or object. If the result is an object, you can then access its keys, otherwise the value will be directly usable as a variable.

x = 'alice'
y = {'x':'bob'}
z = [x,y]
console.log(typeof(z[0])) // string
console.log(typeof(z[1])) // object

Answer №2

Resolved by utilizing the "cast to any" method.

In the following code snippet:

  
  ...
  mounted() {
    this.row.columns.forEach(element => {
      if (element.show === this.headerMobile) {
        this.titleLabel = element.label;
        const data: any = this.row.data;
        this.titleLabelValue = data[element.show];
      }
    });
  }
  ...
