1.在公共方法中（如 public.js 中），加入函數防抖和節流方法
// 防抖
export default {
_debounce(fn, delay) {
var delay = delay || 200;
var timer;
return function () {
var th = this;
var args = arguments;
if (timer) {
clearTimeout(timer);
}
timer = setTimeout(function () {
timer = null;
fn.apply(th, args);
}, delay);
};
},
// 節流
_throttle(fn, interval) {
var last;
var timer;
var interval = interval || 200;
return function () {
var th = this;
var args = arguments;
var now = +new Date();
if (last && now - last < interval) {
clearTimeout(timer);
timer = setTimeout(function () {
last = now;
fn.apply(th, args);
}, interval);
} else {
last = now;
fn.apply(th, args);
}
}
}
}
2.在需要使用的組件引用
import { public } from "@/utils/public";
3.在 methods 中使用
methods: {
changefield: public._debounce(function(_type, index, item) {
// do something ... }, 200)
}
