微信小程序实现图片轮播及文件上传
刚刚接触微信小程序，看着网上的资源写了个小例子，本地图片轮播以及图片上传。
图片轮播：
index.js
rush:js;">
imgurls:[
'../images/1.jpg','../images/2.jpg','../images/3.jpg','../images/4.jpg'
],indicatorDots: true,//是否出现焦点
autoplay: true,//是否自动播放
interval: 2000,//自动播放时间间隔
duration: 1000,//滑动动画时间
userInfo: {}
},onLoad:function(){
console.log('onLoad Test');
}
})
index.wxml:
rush:xml;">
utoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
imgurls}}">
index.json:
rush:js;">
{
"navigationBarTitleText": "相册"
}
index.wxss:
rush:js;">
.slide-image{
width:100%;
height:100%;
}
.swiper_i{
text-align: center;
width:100%;
}
接下来是图片上传的。因为没有服务器，暂时不能上传，但是可以从本地相册或拍照获取照片。
upload.js:
rush:js;">
var app = getApp()
Page({
data:{
// text:"这是一个页面"
source: '',tt:false
},/**
* 选择相册或者相机 配合上传图片接口用
*/
onLoad: function() {
var that = this;
wx.chooseImage({
count: 1,//original原图，compressed压缩图
sizeType: ['original'],//album来源相册 camera相机
sourceType: ['album','camera'],//成功时会回调
success: function(res) {
//重绘视图
that.setData({
source: res.tempFilePaths,tt:true
})
/* var tempFilePaths = res.tempFilePaths
wx.uploadFile({
url: 'https://',//仅为示例，非真实的接口地址
filePath: tempFilePaths[0],name: 'file',formData:{
'user': 'test'
},success: function(res){
var data = res.data
//do something
}
})*/
}
})
},/*onHide:function(){
this.setData({
source:''
})
}*/
})
upload.json:
upload.wxml:
rush:js;">
上传
upload.wxss:
rush:js;">
/* pages/upload/upload.wxss */
.Container{
text-align:center;
width:100%;
}
.image-i{
width:100%;
height:100%;
}
app.js为空。
app.json:
rush:js;">
{
"pages": [
"pages/index/index","pages/upload/upload"
],"window": {
"navigationBarTextStyle": "black","navigationBarTitleText": "演示2","navigationBarBackgroundColor": "#fbf9fe","backgroundColor": "#fbf9fe"
},"networkTimeout": {
"request": 10000,"connectSocket": 10000,"uploadFile": 10000,"downloadFile": 10000
},"tabBar": {
"list": [{
"pagePath": "pages/index/index","text": "显示图片","iconPath": "pages/images/icon_API.png","selectedIconPath": "pages/images/icon_API_HL.png"
},{
"pagePath": "pages/upload/upload","text": "上传","selectedIconPath": "pages/images/icon_API_HL.png"
}]
},"debug": true
}
