本文详细介绍了小程序的开发流程，包括环境搭建、页面布局、组件使用、API调用及调试技巧等关键信息，适合初学者和进阶开发者阅读。

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

{
	"code": 200,
	"data": {
		"data": [{
			"_index": "index_userinfo",
			"_type": "user_info",
			"_id": "14",

			"statu": 0
		}],
		"count": 297
	}
}

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
		})
	}
})```
