本文实例讲述了jQuery实现的上拉刷新功能组件。分享给大家供大家参考，具体如下：

技术要点：

1、jQuery的插件写法

2、上拉刷新步骤分解

3、css样式

jQuery的插件写法：

$.fn.pluginName = function() {
  return this.each(function () {
    fn();
  })
};

上拉刷新步骤分解：

上拉刷新可以分解成三个部分：一是开始（start），记录当前鼠标的位置；二是移动（move），根据下拉的位移响应不同的视图；三是结束（end），刷新页面。

;!function ($) {
  "use strict";
  var PTR = function (ele) {
    this.container = $(ele);
    this.container.addClass('pull-to-refresh');
    this.distance = 60; // 设置参考的下拉位移
    this.attachEvent();
  };
  // 判断是否有touch事件发生
  var isTouch = (function () {
    var isSupportTouch = !!'ontouchstart' in document || window.documentTouch;
    return isSupportTouch;
  })();
  var touchEvents = {
    start: isTouch "htmlcode">

<script src="/UploadFiles/2021-04-02/jquery-1.8.3.min.js">


CSS代码如下：





.pull-to-refresh {
  margin-top: -50px;
  transition: transform .4s;
}
.pull-to-refresh .pull-to-refresh-preloader,
.pull-to-refresh .up,
.pull-to-refresh .refresh {
  display: none;
}
.pull-to-refresh.refreshing {
  transform: translate3d(0,50px,0);
}

.refreshing .pull-to-refresh-arrow,
.refreshing .down,
.refreshing .up {
  display: none;
}
.refreshing .refresh,
.refreshing .pull-to-refresh-preloader {
  display: inline-block;
}
.pull-to-refresh_layer {
  height: 30px;
  line-height: 30px;
  padding-bottom: 10px;
}
.pull-down .pull-to-refresh_layer .up,
.pull-down .pull-to-refresh_layer .refresh {
  display: none;
}
.pull-down .pull-to-refresh_layer .down{
  display: inline-block;
}
.pull-up .pull-to-refresh_layer .up{
  display: inline-block;
}

.pull-up .pull-to-refresh_layer .down,
.pull-up .pull-to-refresh_layer .refresh {
  display: none;
}

.pull-up .pull-to-refresh-arrow {
  transform: rotate(180deg) translate3d(0, 0, 0);
}
.pull-to-refresh-arrow {
  display: inline-block;
  z-index: 10;
  margin-right: 4px;
  transition-duration: 300ms;
  transform: rotate(0deg) translate3d(0, 0, 0);
}

.pull-to-refresh_layer {
  display: inline-block;
}
.pull-to-refresh-preloader {
  display: inline-block;
}
.pull-down {

}
.pull-up {

}
.down {
  display: inline-block;
}
.up {
  display: inline-block;
}
.refresh {
