VUE防止多次点击，重复请求

添加自定义文件 preventReClick.js

import Vue from 'vue'

const preventReClick = Vue.directive('preventReClick', {
    inserted: function (el, binding) {
        el.addEventListener('click', () => {
            if (!el.disabled) {
                el.disabled = true
                setTimeout(() => {
                    el.disabled = false
                }, binding.value || 3000)
            }
        })
    }
});

export { preventReClick }

需要的文件引入
import preventReClick from './store/preventReClick' //防多次点击，重复提交
<el-button class="common-button" size="small" type="primary" @click="handleSave('form')" v-preventReClick>保 存</el-button>

vue 中使用防抖和节流，防止重复点击或重复上拉加载

/**
 * 函数防抖 (只执行最后一次点击)
 * @param fn
 * @param delay
 * @returns {Function}
 * @constructor
 */
export const Debounce = (fn, t) => {
    let delay = t || 500;
    let timer;
    console.log(fn)
    console.log(typeof fn)
    return function () {
        let args = arguments;
        if(timer){
            clearTimeout(timer);
        }
        timer = setTimeout(() => {
            timer = null;
            fn.apply(this, args);
        }, delay);
    }
};
 
 
/**
 * 函数节流
 * @param fn
 * @param interval
 * @returns {Function}
 * @constructor
 */
export const Throttle = (fn, t) => {
    let last;
    let timer;
    let interval = t || 500;
    return function () {
        let args = arguments;
        let now = +new Date();
        if (last && now - last < interval) {
            clearTimeout(timer);
            timer = setTimeout(() => {
                last = now;
                fn.apply(this, args);
            }, interval);
        } else {
            last = now;
            fn.apply(this, args);
        }
    }
};

用法

methods:{
	getAliyunData:Throttle(function(){
	...
	 },1000),
}
