kandi X-RAY | scrollToAnchor Summary

scrollToAnchor is a HTML library. scrollToAnchor has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A simple, pure javascript animation that scrolls the page to anchors. It works on all somewhere in the page, as long as the first character in the string is a hash. Then the body will scroll to that point in the page when the link is clicked. The time taken to scroll to the point is a function of the distance from the current point in the page, to the target. So the further away the point the longer it takes, with a minimun of 1 second for distances less than 500 pixels and a maximum of 2.5 seconds for distances greater than 2500 pixels. All for about 0.4kb when minified and gzipped.

QUESTION

Active-indication in top menu to stay in sync while the user scrolls manually

Asked 2021-Apr-18 at 13:46

I have a single HTML page with several sections to which the user can navigate by clicking the corresponding link at the top. That link will get highlighted when the user navigates via that link.

Now I would like that when the user scrolls up or down manually, and a different section comes into view, that the corresponding link in the top menu will get the highlight.

My attempt is in the scroll event handler, but I am facing an issue with finding the HTML section anchor id that corresponds to the current scroll position.

Note that I am required to produce the li dynamically -- so that cannot change: the ul must be empty as per requirements of my project so all list items and hyperlinks must be generated in JavaScript (as it is currently done).

Here is my page. My problem is in the scroll event handler:

There are some issues:

The expression pageYOffset >= (topSction - sctionHeight / 1) is not correct. Subtracting the height of the section from its top offset is without meaning. Instead, make your loop interruptable (use for instead of forEach) and check whether pageYOffset + top < topSction + sctionHeight. If so, break out of the loop as searching further is no longer needed: we found the section.
Take into account that the menu bar at the top makes part of the section invisible, so make sure that the logic of the point above takes this offset into account. Define top as menu.offsetTop + menu.clientHeight, where menu is the .navbar__menu element.
li.classList.contains('current') is a condition that is never true, as you don't have a current CSS class. You wanted to refer here to the variable current, but use a literal string instead. Moreover, the value of current (e.g. "section3") will not be found in the class list of the li element. You could look for it in the href attribute of the child a elements:

Changing (e: Event) to just (e) works.

Argument of type 'MonoTypeOperatorFunction' is not assignable to parameter of type 'OperatorFunction'.

I guess there are two different types of events, and what the filter is receiving is not the same type of Event that the router.events has in it.

Not declaring the type received resolves this issue.

ANSWER

Answered 2019-Sep-16 at 11:14

You can add or subtract any number inside your .animate function.

You can use a hardcoded value (like I did in the example) or you can also get the actual size of an element and then add/subtract this value until you have the exact position you need to scroll to.

.animate scroll nested div

Asked 2017-Dec-17 at 18:58

I am setting up a site that has parallaxing nested divs and I'm attempting to animate the scroll to each div. The problem im running into is that most .animate scrollto's I'm finding are relying on the html,body which is where I think I'm having a problem since the scrolling happens to the parent div vs. the body of the page. I've set up a fiddle that gives the basic outline of the site with simple anchor tags that take you to the next nested div/section. I am attempting to animate the scroll between each one vs. jumping to the next anchor. Can someone point me in the right direction? Here is the fiddle link

Answered 2017-Dec-08 at 20:17

I would approach this doing a more generic solution, where you use a data attribute to indicate which element should be scrolled to upon clicking the element.

For instance,

··· would scroll to the element with id other-element. Please see the following for a working example:
