사용법
$isBreakpoint() 함수를 사용할 수 있다.
ex) lg 이상일때 div 보이기
[code]
<div x-show="show">메뉴</div>
<script type="text/javascript">
window.addEventListener('alpine:init', () => {
Alpine.data('mydata', () => ({
show: false,
init() {
window.addEventListener('resize', () => {
this.resizeHandler();
});
this.resizeHandler();
},
resizeHandler() {
if (this.$isBreakpoint('lg')) {
this.show = true;
} else {
this.show = false;
}
},
}));
});
</script>
[/code]
