jQuery: resetting scroll bar on clicking a button

Question

This is a peculiar issue faced when creating internal links on a WordPress page. There are 3 CTA buttons on the page that when clicked do jump to the respective sections on the same page. However, it is jumping past the section exactly by the height of the header of the page. As a solution, I added a function to each of these buttons so that it sets the scrollbar to pull the bar backward. Below is the code that isn't working. Could you please suggest some changes to make it work?

In your code it is missing where you are calling the resetScrollpoint() function but but at first sight you can do this ...

<a class="btn" role="button" href="javascript:void(0)" onclick="resetScrollpoint('#faqs')">FAQs</a>
<a class="btn" role="button" href="javascript:void(0)" onclick="resetScrollpoint('#let-us-chat')">Schedule a Call</a>
<a class="btn" role="button" href="javascript:void(0)" onclick="resetScrollpoint('#submit-questions')">Submit a Question</a>

And your function change to this:

resetScrollpoint(selector){
    if(!selector) return;
    window.scroll(0,jQuery(selector).offset().top - jQuery('#header').height());
}

Explanations Sorry for my English!

Your first aproach are right

<a class="btn" role="button" href="#faqs">FAQs</a>

That get the #faqs element scrolling to top, but the top is 0 and you have a fixed #header element so you need to scroll to top + #header height

Your second aproach with onclick="resetScrollpoint()" are also right but

1. Is ambiguos because on the one hand you tell the interpreter to execute href="#faqs" but on the other hand you tell to interpreter to execute resetScrollpoint(). Solution: with href="javascript:void(0)" you tell to interpreter to ignore the default href action

2. The logical inside your function resetScrollpoint() was wrong because you need to know how many pixels you need to scroll.

Solution: you tell to the function what is the element that you need (passing it as a parameter) resetScrollpoint('#faqs'),

with jQuery(selector).offset().top you find the position of your element received by the parameter selector (how many pixels from the top) and substract the height of #header element because otherwise the scrolling it would be too upstair
