|
* mescroll-body 基于page滚动的下拉刷新和上拉加载组件, 支持嵌套原生组件, 性能好
|
||
|
* @property {Object} down 下拉刷新的参数配置
|
||
|
* @property {Object} up 上拉加载的参数配置
|
||
|
* @property {Object} i18n 国际化的参数配置
|
||
|
* @property {String, Number} top 下拉布局往下的偏移量 (支持20, "20rpx", "20px", "20%"格式的值, 其中纯数字则默认单位rpx, 百分比则相对于windowHeight)
|
||
|
* @property {Boolean, String} topbar 偏移量top是否加上状态栏高度, 默认false (使用场景:取消原生导航栏时,配置此项可留出状态栏的占位, 支持传入字符串背景,如色值,背景图,渐变)
|
||
|
* @property {String, Number} bottom 上拉布局往上的偏移量 (支持20, "20rpx", "20px", "20%"格式的值, 其中纯数字则默认单位rpx, 百分比则相对于windowHeight)
|
||
|
* @property {Boolean} safearea 偏移量bottom是否加上底部安全区的距离, 默认false (需要适配iPhoneX时使用)
|
||
|
* @property {Boolean} fixed 是否通过fixed固定mescroll的高度, 默认true
|
||
|
* @property {String, Number} height 指定mescroll最小高度,默认windowHeight,使列表不满屏仍可下拉
|
||
|
* @property {Boolean} bottombar 底部是否偏移TabBar的高度 (仅在H5端的tab页生效)
|
||
|
* @property {Boolean} sticky 是否支持sticky,默认false; 当值配置true时,需避免在mescroll-body标签前面加非定位的元素,否则下拉区域无法隐藏
|
||
|
* @event {Function} init 初始化完成的回调
|
||
|
* @event {Function} down 下拉刷新的回调
|
||
|
* @event {Function} up 上拉加载的回调
|
||
|
* @event {Function} emptyclick 点击empty配置的btnText按钮回调
|
||
|
* @event {Function} topclick 点击回到顶部的按钮回调
|
||
|
* @event {Function} scroll 滚动监听 (需在 up 配置 onScroll:true 才生效)
|
||
|
* @example <mescroll-body @init="mescrollInit" @down="downCallback" @up="upCallback"> ... </mescroll-body>
