vue3.0 时间戳转时间

由于 3.0 移除了2.0 的 filters 后，

所以在3.0中，设置：

<script lang="ts">
    export default defineComponent({
        name: "Home",
        setup() {
            // 时间戳转时间
            function formatDate(value: string|number|Date) {
                let date = new Date(value);
                let y = date.getFullYear();
                let MM = date.getMonth() + 1 as number;
                MM = MM < 10 ? ('0'+MM) as unknown as number : MM;
                let d = date.getDate();
                d = d < 10 ? ('0' + d) as unknown as number : d;
                let h = date.getHours();
                h = h < 10 ? ('0' + h) as unknown as number : h;
                let m = date.getMinutes();
                m = m < 10 ? ('0' + m) as unknown as number : m;
                let s = date.getSeconds();
                s = s < 10 ? ('0' + s) as unknown as number : s;
                return y + '-' + MM + '-' + d + ' ' + h + ':' + m + ':' + s;
            };
　　　　}
　　　　return{
          formatDate,
　　　　}
    });
</script>
