How can I do this in Ionic without jquery?
var window_top = jQuery(window).scrollTop() + 56;
var div_top = jQuery('#sticky-anchor').offset().top;
You can use a reference to the Content
:
import { Component, ViewChild } from '@angular/core';
import { Content } from 'ionic-angular';
@Component({...})
export class MyPage{
@ViewChild(Content) content: Content;
scrollToTop() {
this.content.scrollToTop();
}
scrollTo(elementId:string) {
let yOffset = document.getElementById(elementId).offsetTop;
this.content.scrollTo(0, yOffset, 4000)
}
}
There are a lot of properties that you can use; one of the most importants is...
getContentDimensions()
: Returns the content and scroll elements' dimensions.
Property Type Details
dimensions.contentHeight number content offsetHeight
dimensions.contentTop number content offsetTop
dimensions.contentBottom number content offsetTop+offsetHeight
dimensions.contentWidth number content offsetWidth
dimensions.contentLeft number content offsetLeft
dimensions.contentRight number content offsetLeft + offsetWidth
dimensions.scrollHeight number scroll scrollHeight
dimensions.scrollTop number scroll scrollTop
dimensions.scrollBottom number scroll scrollTop + scrollHeight

dimensions.scrollLeft number scroll scrollLeft
dimensions.scrollRight number scroll scrollLeft + scrollWidth
