大家好,又见面了,我是你们的朋友全栈君。
2020/9/1:这种写法能实现但是用了多次缓存,后面发现其实是可以用自定义属性来传参的,具体有空我会写出来
效果展示:
列表页js部分:
onLoad: function(options) {
var that = this;
wx.request({
url: ‘你的接口’,
data: {
接口参数
},
header: {
‘content-type’: ‘application/json’, // 默认值
},
success: function (res) {
console.log(res.data);
that.setData({
你定义的变量名: res.data,
})
}
})
},
跳转详情页方法
viewDetail: function(e) {
let newsid = e.currentTarget.dataset.id || ”;
let newsTitle = e.currentTarget.dataset.newstitle || ”;
let newsAuthor = e.currentTarget.dataset.newsauthor || ”;
let newsDescription = e.currentTarget.dataset.newsdescription || ”;
let newsCreateTime = e.currentTarget.dataset.newscreatetime || ”;
let newsContentText = e.currentTarget.dataset.newscontenttext || ”;
let newsInfoSource = e.currentTarget.dataset.newsinfosource || ”;//你想传递的值
//放入缓存
wx.setStorage({
key: ‘你定义key的名程’,
data: {
newsid,
newsAuthor,
newsTitle,
newsDescription,
newsCreateTime,
newsContentText,
newsInfoSource
},
success: function () {
wx.navigateTo({
url: ‘../news_home/Detail/Detail?newsid=’ newsid “&newsTitle” newsTitle “&newsAuthor” newsAuthor
“&newsDescription” newsDescription “&newsCreateTime” newsCreateTime “&newsContentText” newsContentText
“&newsInfoSource” newsInfoSource
})
}
})
},
列表页wxml:
用data-绑定传递
<view class=” bindtap=’viewDetail’ data-newsid='{ {item.newsid}}’ data-newstitle='{ {item.Title}}’ data-newsauthor='{ {item.Author}}’ data-newsdescription='{ {item.Description}}’ data-newscreatetime='{ {item.CreateTime}}’ data-newscontenttext='{ {item.ContentText}}’ data-newsinfosource='{ {item.InfoSource}}’>
<view style=”width:100%”>标题:{ {item.Title}}</view>
<view style=”width:100%”>作者:{ {item.Author}}</view>
<view style=”width:100%”>发布时间:{ {item.CreateTime}}</view>
</view>
详情页js:
从缓存中拿取数据
onShow: function () {
let that = this;
// 从缓存中获取
wx.getStorage({
key: ‘你定义key的名字’,
success: function (res) {
that.setData({
newsTitle: res.data.newsTitle,
newsAuthor:res.data.newsAuthor,
newsDescription:res.data.newsDescription,
newsCreateTime:res.data.newsCreateTime,
newsContentText:res.data.newsContentText,
newsInfoSource:res.data.newsInfoSource
})
},
})
},
详情页xwml:
<view>{ {newsInfoSource}}</view>
