Trying to modify a read-only property in Ionic 2 and Angular 2 is causing an error

Utilizing the Ionic refresh API allows for pulling and refreshing a page with updates to be accomplished.

Within an Angular2 page, I am trying to use the refresh method to clear existing rows and then add new rows using the .push() method. However, when I attempt to clear the property using this.rows = [], I encounter the following error.

8 470644 error EXCEPTION: TypeError: Attempted to assign to readonly property. in [rows in ListPage@25:30]

Is there an alternative method for clearing the previous array for the this.rows property?

Answer №1

Instead of reassigning the rows array, make modifications to the existing one:

this.rows.length = 0;

By setting the array length to 0, you effectively clear the array in place by making modifications.
