js定义

/**

 * @param {number} to

 * @param {number} duration

 * @param {Function} callback

 */

export const scrollTo = (to: number, duration: number, callback?: any) => {

  const start = position();

  const change = to - start;

  const increment = 20;

  let currentTime = 0;

  duration = typeof duration === "undefined" ? 500 : duration;

  const animateScroll = function () {

    // increment the time

    currentTime += increment;

    // find the value with the quadratic in-out easing function

    const val = easeInOutQuad(currentTime, start, change, duration);

    // move the document.body

    move(val);

    // do the animation unless its over

    if (currentTime < duration) {

      requestAnimFrame(animateScroll);

    } else {

      if (callback && typeof callback === "function") {

        // the animation is done so lets callback

        callback();

      }

使用

 


    

  



function handleSizeChange(val: number) {

  emit("pagination", { page: currentPage, limit: val });

  if (props.autoScroll) {

    scrollTo(0, 800);

  }

}



function handleCurrentChange(val: number) {

  currentPage.value = val;

  emit("pagination", { page: val, limit: props.limit });

  if (props.autoScroll) {

    scrollTo(0, 800);

  }

}
