Why we need this ???
Problem statement
I want to alert "Too small" if client try to resize element #ex below width 50px and height 50px
Before using this
const target = $("#ex");
const ro = new ResizeObserver(entries => {
for(let entry of entries) {
if (entry.target == target[0]) {
if (target.width() < 50 || target.height() < 50) alert("Too small");
}
}
});
ro.observe(target[0]);
Note: Above example require JQuery
After using this
$("#ex").on("resize",function(e) {
if ($(this).width() < 50 || $(this).height() < 50) alert("Too small");
});
Note: Above example require JQuery
Difference
- First and final block obviously shorter.
- Closer to english language.
- Remember easier.
Without JQuery
evx.on(document.getElementById("ex"),"resize",function(e) {
if ($(this).width() < 50 || $(this).height() < 50) alert("Too small");
});
Yeah, still simple and easy.
