How to reload the current page on click of a button in ionic 2?

Question

I have a requirement where I have refresh the contents of the current page onclick of the refresh button in the current page.I went through few websites but I am not quite clear about this functionality.Could anyone suggest me how to do this?

Solution

Onclick of your refresh button, you could call the page event method ionViewWillEnter()

From the official docs --> ionViewWillEnter() Runs when the page is about to enter and become the active page.

HTML

<button (click)="refreshPage()">Refresh Page</button>

Typescript

    ionViewWillEnter(){
            this.myDefaultMethodToFetchData();
        }

    refreshPage() {
        this.ionViewWillEnter();
    }

    myDefaultMethodToFetchData(){
        ...Do Something, when the page opens...
    }
