Is there a way to have ResizeObserver only trigger on width changes and not on height changes?
For example:
const resizeObserver = new ResizeObserver(updateLayout);
resizeObserver.observe(layout.current);
const updateLayout = () => {/*perform action*/}
If you need to detect changes in width within an element, you can create a custom function that specifically checks for this:
const checkWidthChange = function($element, callback) {
let lastDimensions = $element.getBoundingClientRect();
const observer = new ResizeObserver(function() {
const currentDimensions = $element.getBoundingClientRect();
if(currentDimensions.width !== lastDimensions.width && currentDimensions.height === lastDimensions.height)
callback();
lastDimensions = currentDimensions;
});
observer.observe($element);
}
You can then implement it like so:
checkWidthChange(layout.current, setLayout);
