vue 防抖节流，开箱即用

vue 防抖节流，开箱即用

在util下建个下图文件名
将下方代码放到文件中

const debounce = (func, time, isDebounce, ctx) => {
    var timer, lastCall, rtn;
    //防抖函数
    if (isDebounce) {
        rtn = (...params) => {
            if (timer) clearTimeout(timer);
            timer = setTimeout(() => {
                func.apply(ctx, params);
            }, time);
        };
    } else {//节流函数
        rtn = (...params) => {
            const now = new Date().getTime();
            if (now - lastCall < time && lastCall) return;
            lastCall = now;
            func.apply(ctx, params);
        };
    }
    return rtn;
};

export default {
    name: 'Debounce',
    abstract: true,
    props: {
        time: {
            type: Number,
            default: 800,
        },
        events: {
            type: String,
            default: 'click',
        },
        isDebounce: {
            type: Boolean,
            default: false,
        },
    },
    created() {
        this.eventKeys = this.events.split(',');
        this.originMap = {};
        this.debouncedMap = {};
    },
    render() {
        const vnode = this.$slots.default[0];
        this.eventKeys.forEach(key => {
            const target = vnode.data.on[key];
            if (target === this.originMap[key] && this.debouncedMap[key]) {
                vnode.data.on[key] = this.debouncedMap[key];
            } else if (target) {
                this.originMap[key] = target;
                this.debouncedMap[key] = debounce(
                    target,
                    this.time,
                    this.isDebounce,
                    vnode
                );
                vnode.data.on[key] = this.debouncedMap[key];
            }
        });
        return vnode;
    },
};

在main.js文件中导入，使用时按照下方注释放在按钮的外方，设置好时间，设置好是防抖还是节流的参数，即可使用
下面附上使用代码，我这里使用的是防抖，可根据使用情况换成防抖或节流

<Debounce :time='1000' !isDebounce>
  <div class="submit" @click="present">提交</div>
</Debounce>
