一、基于VUE
/**
* @description: 点击事件防爆点
* @param {type} func：正常点击处理事件，wait：延迟事件
* @return: 防爆点
* @author: me
*/
export function throttle (func, wait) {
let context, args, prevArgs, argsChanged, result;
let previous = 0;
return function () {
let now, remaining;
if (wait) {
now = Date.now();
remaining = wait - (now - previous);
}
context = this;
args = arguments;
argsChanged = JSON.stringify(args) != JSON.stringify(prevArgs);
prevArgs = {...args};
if ((argsChanged || wait) && (remaining <= 0 || remaining > wait)) {
if (wait) {
previous = now;
}
result = func.apply(context, args);
context = args = null;
}
return result;
};
}
import {throttle} from '@/common/common';
created () {
// 点击事件节流
this.throttleInit();
},
methods: {
throttleInit () {
this.remoteMethod = throttle(this.savePic, 300);
this.selectFontCli = throttle(this.selectFont, 300);
},
}
二、基于jQ
