修改小程序data里 数组中某个对象
Page({
data: {
latitude: '',
longitude: '',
markers: [{
iconPath: '../../images/ovaddress.png',
id: 0,
latitude: '',
longitude: '',
width: 25,
height: 30
}],
enable_traffic:true
},
})
要修改 markers中latitude和longitude
onLoad:function(options){
this.setData({
'markers[0].longitude': options.longitude,
'markers[0].latitude': options.latitude
})
}
要用单引号引起来。
还有一种数据修改，是未确定是数组中的第几个，要动态修改。格式是如下

修改这个data数据中的某个数据
Page({
data:{
listData:listData//这里的listData指的是上面的数据
},
//点击事件
tab(e){
var index= e.currenTarget.dataset.index
var setListData = 'listData['+index+'].statu'
//要用引号引起来
// index是动态的第几个
//var setListData = 'this.data.listData['+index+'].statu'
//这里不写this.data 是因为下面修改已经指定了thisl
this.setData({
[setListData]:1
//上面申明的变量 在这里要用【】括起来
})
}
})```
