问题描述
我正在调用一个返回对象的api
I am calling an api which returns an object
var rain = data[i].rain; $.get( "api.openweathermap/data/2.5/forecast?q=London,uk&mode=json&units=metric", function( data ) { var data = data.list; for(var i = 0; i < 12; i++){ var rain = data[i].rain; console.log(rain) } });当我检查控制台时,雨返回以下内容:
rain returns the following when I inspect the console:
Object {3h: 0.005} Object {3h: 0.03}我预计 rain.3h 会让我访问0.005和0.03,但事实并非如此。我收到以下错误消息:意外的令牌ILLEGAL
I expected that rain.3h would have given me access to 0.005 and 0.03, but it doesn't. I get the following error message : Unexpected token ILLEGAL
这是因为它以数字开头吗?任何人都可以建议如何访问这个属性?
Is this because it begins with a number? Can anyone advise how to access this property?
推荐答案是的,因为它以数字开头。
Yes it's because it begins with a number.
你可以这样访问:
rain['3h']如果您有以数字或符号命名的对象属性,请使用括号表示法。
When you have object properties named with numbers or simbols, use the bracket notation.
