zarm-web/es/utils/debounce.js

基于 React 的桌面端UI库

export default function debounce(func, wait, immediate) {
  let timeout;
  let result;
  return function debounced(...args) {
    if (timeout) {
      clearTimeout(timeout);
    }

    if (immediate) {
      const callNow = !timeout;
      timeout = setTimeout(() => {
        timeout = null;
      }, wait);

      if (callNow) {
        result = func.apply(this, args);
      }
    } else {
      timeout = setTimeout(() => {
        func.apply(this, args);
      }, wait);
    }

    return result;
  };
}
