let NavBar = document.getElementById("xdd");
let bound = NavBar.getBoundingClientRect();
window.onscroll= function (){
console.log("scrolled")
console.log(bound)
if(bound.top >=0)
{
}

</html>I am trying to detected whether an Elemnt is inside the Viewport. When i looked this up, i was directed to usimg getBoundingClientRect to get its location relative to the Viewport.
However, when i tried implementing this solution, it didnt work, as this always returned a DOMRect with the x,y, top and left values being 0 and the others staying constant no matter where i scroll.
The html element(s) i want to get the location of:
<header id="TNav">
<nav class="TopNavigation" id="xdd">
<button class="TopNavBtn">xd</button>
</nav>
</header>
Its CSS:
header{
height: 5vh;
grid-column: 1/3;
grid-row:1/2 ;
background-color: black;
z-index: 2;
display: block;
}
.TopNavigation{
display: flex;
flex-direction: column;
}
The JS code:
let NavBar = document.getElementById("xdd");
let bound = NavBar.getBoundingClientRect();
window.onscroll= function (){
console.log("scrolled")
console.log(bound)
if(bound.top >=0)
{
}
else
{
console.log("isnt")
}
}
// to check if the DOM is loaded
document.addEventListener("DOMContentLoaded", (event) =>{
console.log("ready");
})
the code is implemented at the very bottom of the <body>.
I tried testing if the DOM is loaded and changing which element i read the location of.
Here is what the the getBoundingClientRect() returns:
Thanks to user Unmitigated, i now have the answer:
The
let bound = NavBar.getBoundingClientRecthad to be moved inside thewindow.onscrollevent handler, like so:
