I’m trying to implement a directive to hide the Toolbar while scrolling. I tried using this tutorial: https://medium.com/@gregor.srdic/ionic3-hidding-header-on-footer-on-content-scroll-15ab95b05dc5
This worked with Ionic 3, but doesn’t work with Ionic 4.
On the following code I get the error:
private adjustElementOnScroll(ev) {
if (ev) {
console.log(ev);
ev.domWrite(() => {
let scrollTop: number = ev.scrollTop > 0 ? ev.scrollTop : 0;
let scrolldiff: number = scrollTop - this.lastScrollPosition;
this.lastScrollPosition = scrollTop;
let newValue = this.lastValue + scrolldiff;
newValue = Math.max(0, Math.min(newValue, this.config.maxValue));
this.renderer.setStyle(this.element.nativeElement, this.config.cssProperty, `-${newValue}px`);
this.lastValue = newValue;
});
}
}
Error:
ev.domWrite is not a function
I checked, and ev in Ionic 4 is a CustomEvent , not a ScrollEvent .
Any suggestions?
