I have the following scenario: I have an API which returns multiple div's. And in my UI, I have one parent div in which i need to show these div's. The condition is, if child div is overflowing parent, I need to show them on next page.
For eg: lets say my API is returning string like this:
<div class="ab0"></div>
<div class="ab1"></div>
<div class="ab2"></div>
<div class="ab3"></div>
<div class="ab4"></div>
and the parent div can fit in only ab0, ab1, ab2. Then I want to show these 3 div's 1st and when user click on '>' symbol I need to show ab3, ab4. Also if ab2 is partially overflowing and if I can show only overflowing part on next page, that will be great.
Is there any way I can do this.
Thanks in advance
A simple suggestion is to use the system's scroll functionality.
The system 'knows' how much it can show at once and as long as you can find out the height of the parent div you can move up and down the children (or part children if an exact number don't fit into the parent at once) using Javascript scrollTop.
const parent = document.querySelector('.parent');
const h = parent.offsetHeight;
let page = 0;
const lastPage = Math.floor((parent.scrollHeight + 1) / h);
function next() {
if (page < lastPage) {
page++;
parent.scrollTop = parent.scrollTop + h;
}
}
function prev() {
if (page > 0) {
page--;
parent.scrollTop = parent.scrollTop - h;
}
}
.parent {
height: 64px;
overflow: auto;
}
.parent div {
height: 2em;
border: 1px solid;
position: relative;
}
button {
font-size: 2em;
}
<div class="parent">
<div class="ab0">0</div>
<div class="ab1">1</div>
<div class="ab2">2</div>
<div class="ab3">3</div>
<div class="ab4">4</div>
</div>
<button onclick="prev();"><</button>
<button onclick="next();">></button>
</button>
