npm i -S easy-fmt
or
yarn add easy-fmt使用
import fmt from "easy-fmt";
let io = fmt.IntersectionObserver(document.getElementById("box", true));
io.then((entries, observe) => {
if (entries[0].intersectionRatio <= 0) return;
// 元素在可视区的处理逻辑
observe.disconnect();
});
fmt.currency(12000); // 12,000.00
fmt.time(new Date(2020, 10, 22, 10, 15, 2), "YYYY-MM-DD hh:mm:ss"); // 2020-11-22 10:15:02
fmt.param({
orderId: 15,
orderNo: "Order20201022",
}); // ?orderId=15&orderNo=Order20201022
fmt.prefixZero(12, 5); // 00012
fmt.prefixZero(12, 1); // 12
fmt.prefixZero(-12, 3); // -012
fmt.round(12.456, 2); // 12.46
fmt.mask("15211112222", 12, 4); // 15211112222
fmt.mask("15211112222", 3, 4); // 152****2222
fmt.trim(" 152 111 222 ", "all"); // 152111222
fmt.phone("15211112222"); // 152-1111-2222
fmt.phone("15211112222", "/"); // 152/1111/2222
fmt.phone("15211112222", "-", "1/1/1"); // 1-5-2-11112222API
