zarm-web/es/utils/throttle.js

基于 React 的桌面端UI库

const throttle = (func, delay) => {
  let timer;
  let startTime = Date.now();
  return (...args) => {
    const curTime = Date.now();
    const remaining = delay - (curTime - startTime);
    clearTimeout(timer);

    if (remaining <= 0) {
      func.apply(this, args);
      startTime = Date.now();
    } else {
      timer = setTimeout(func, remaining);
    }
  };
};

export default throttle;
