Scroll to a specific Element Using html
Yes you use this
<a href="#google"></a>
<div id="google"></div>
But this does not create a smooth scroll just so you know.
You can also add in your CSS
html {
scroll-behavior: smooth;
}
How do I scroll to an element using JavaScript?
You can use an anchor to "focus" the div. I.e:
<div id="myDiv"></div>
and then use the following javascript:
// the next line is required to work around a bug in WebKit (Chrome / Safari)
location.href = "#";
location.href = "#myDiv";
How to scroll to an element?
<div id="componentToScrollTo"><div>
<a href='#componentToScrollTo'>click me to scroll to this</a>
This is all you need.
Scroll to an element with jQuery
Assuming you have a button with the id button
, try this example:
$("#button").click(function() {
$([document.documentElement, document.body]).animate({
scrollTop: $("#elementtoScrollToID").offset().top
}, 2000);
});
I got the code from the article Smoothly scroll to an element without a jQuery plugin. And I have tested it on the example below.
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script>
$(document).ready(function (){
$("#click").click(function (){
$('html, body').animate({
scrollTop: $("#div1").offset().top
}, 2000);
});
});
</script>
<div id="div1" style="height: 1000px; width 100px">
Test
</div>
<br/>
<div id="div2" style="height: 1000px; width 100px">
Test 2
</div>
<button id="click">Click me</button>
</html>
Javascript scroll to specific element by ID
You don't have to compute any value to do what you want, and don't have to use JavaScript at all. At least, as you don't want a smooth scrolling.
You can easily scroll to any element with it id setting the href
attribute :
<a href="#my_id" id="my_link">Click me to scroll down</a>
...
<section id="my_id">...</section>
Ok, according to your comment, there is a conflict with the angular's Router when doing this, so with a little bit of JavaScript you can solve the problem :
document.getElementById("my_link").addEventListener("click",(e)=>{
e.preventDefault();
document.querySelector(e.currentTarget.href).scrollIntoView();
});

How to scroll to an element inside a div?
You need to get the top offset of the element you'd like to scroll into view, relative to its parent (the scrolling div container):
var myElement = document.getElementById('element_within_div');
var topPos = myElement.offsetTop;
The variable topPos is now set to the distance between the top of the scrolling div and the element you wish to have visible (in pixels).
Now we tell the div to scroll to that position using scrollTop
:
document.getElementById('scrolling_div').scrollTop = topPos;
If you're using the prototype JS framework, you'd do the same thing like this:
var posArray = $('element_within_div').positionedOffset();
$('scrolling_div').scrollTop = posArray[1];
Again, this will scroll the div so that the element you wish to see is exactly at the top (or if that's not possible, scrolled as far down as it can so it's visible).
