微信小程序 scroll-view实现上拉加载与下拉刷新的实例
实现效果图：
如图，使用小程序的scroll-view实现的上拉加载数据，下拉刷新数据，试下代码如下：
var GetList = function (that) {
that.setData({
hidden: false
});
wx.request({
url: url,data: {
pageSize: 10,pageNo: page
},success: function (res) {
var l = that.data.list
for (var i = 0; i < res.data.length; i++) {
l.push(res.data[i])
}
that.setData({
list: l
});
page++;
that.setData({
hidden: true
});
}
});
}
Page({
data: {
hidden: true,list: [],scrollTop: 0,scrollHeight: 0
},onLoad: function () {
var that = this;
wx.getSystemInfo({
success: function (res) {
console.info(res.windowHeight);
that.setData({
scrollHeight: res.windowHeight
});
}
});
},onShow: function () {
var that = this;
GetList(that);
},bindDownLoad: function () {
var that = this;
GetList(that);
},scroll: function (event) {
this.setData({
scrollTop: event.detail.scrollTop
});
},refresh: function (event) {
page = 1;
this.setData({
list: [],scrollTop: 0
});
GetList(this)
},onPullDownRefresh: function () {
console.log("下拉")
},onReachBottom: function () {
console.log("上拉");
}
})
that.setData({
hidden: false
});
wx.request({
url: url,data: {
pageSize: 10,pageNo: page
},success: function (res) {
var l = that.data.list
for (var i = 0; i < res.data.length; i++) {
l.push(res.data[i])
}
that.setData({
list: l
});
page++;
that.setData({
hidden: true
});
}
});
}
Page({
data: {
hidden: true,list: [],scrollTop: 0,scrollHeight: 0
},onLoad: function () {
var that = this;
wx.getSystemInfo({
success: function (res) {
console.info(res.windowHeight);
that.setData({
scrollHeight: res.windowHeight
});
}
});
},onShow: function () {
var that = this;
GetList(that);
},bindDownLoad: function () {
var that = this;
GetList(that);
},scroll: function (event) {
this.setData({
scrollTop: event.detail.scrollTop
});
},refresh: function (event) {
page = 1;
this.setData({
list: [],scrollTop: 0
});
GetList(this)
},onPullDownRefresh: function () {
console.log("下拉")
},onReachBottom: function () {
console.log("上拉");
}
})
.item{
display: flex;
margin-bottom: 50rpx;
