Json 的 Key中含有空格，怎么取

Question

比如有以下字符串：str=[{"id":1,"invdate":"07-10-1 上午12:00","client id":1,"amount":100,"tax":20,"total":120,"note":"note 1","closed":"No","ship via":""},
{"id":13,"invdate":"07-10-6 上午12:00","client id":3,"amount":1000,"tax":0,"total":1000,"note":"","closed":"No","ship via":""}]
当我用eval(str)后，for(var i=1; i<list.length; i++){
document.write(list[i].client id) ;这个地方怎么x写key值才能吧client id的值取出来
}

Answer 1

document.write(list[i]["client id"]);
