基于jQuery实现下拉刷新上拉加载
作者:互联网
- 上拉刷新的实现:
-
//------------------------下拉刷新------------------------------- //定义的全局变量 var disY, startY, endY; //触摸事件开始时触发 $('.scroll').on('touchstart', function (e) { startY = e.changedTouches[0].pageY; }); //触摸事件移动中时触发 $('.scroll').on('touchmove', function (e) { endY = e.changedTouches[0].pageY; disY = endY - startY; if (disY > 30) { $('.status').css({ display: 'block', height: disY + 'px', }); } }); //触摸事件结束时触发 $('.scroll').on('touchend', function (e) { endY = e.changedTouches[0].pageY; disY = endY - startY; if (disY > 72) { //定义一个定时器,返回下拉到一定的高度 var timer = setInterval(function () { disY -= 13; if (disY <= 60) { $('.status').css({ height: 52 + 'px', }); clearInterval(timer); refresh(); } $('.status').css({ height: disY + 'px', }); }, 75); } }); //请求刷新数据 function refresh() { var t = setTimeout(function () { for (var i = 0; i < 13; i++) { $('.scroll ul').append('<li>' + '添加的数据:' + parseInt(i + 1) + '</li>'); } $('.status').css({ display: 'none', height:0 }); clearTimeout(t) }, 3000); }
- 下拉加载的实现:
-
1 //--------------上拉加载更多--------------- 2 //获取滚动条当前的位置 3 function getScrollTop() { 4 var scrollTop = 0; 5 if (document.documentElement && document.documentElement.scrollTop) { 6 scrollTop = document.documentElement.scrollTop; 7 } else if (document.body) { 8 scrollTop = document.body.scrollTop; 9 } 10 return scrollTop; 11 } 12 13 //获取当前可视范围的高度 14 function getClientHeight() { 15 var clientHeight = 0; 16 if (document.body.clientHeight && document.documentElement.clientHeight) { 17 clientHeight = Math.min(document.body.clientHeight, document.documentElement.clientHeight); 18 } else { 19 clientHeight = Math.max(document.body.clientHeight, document.documentElement.clientHeight); 20 } 21 return clientHeight; 22 } 23 24 //获取文档完整的高度 25 function getScrollHeight() { 26 return Math.max(document.body.scrollHeight, document.documentElement.scrollHeight); 27 } 28 29 //滚动事件触发 30 window.onscroll = function () { 31 if (getScrollTop() + getClientHeight() === getScrollHeight()) { 32 console.log('在这里加载数据咯!'); 33 } 34 }
