如何從這個對象訪問值

Question

如何從這個對象訪問值：

{ 
    "user_voted_1": "1", 
    "user_voted_2": "1", 
    "user_voted_3": "1" 
} 

Answer 1

點標記（object.property）：

console.log(data.user_voted_1); 

Answer 2

假設你的代碼是

var data = { 
    "user_voted_1": "1", 
    "user_voted_2": "1", 
    "user_voted_3": "1" 
}; 

你可以使用以下某種模式訪問屬性：

var x = data.user_voted_1; // x = "1" 
var y = data["user_voted_2"]; // y = "1" 

請注意，如果您遇到問題，我建議在繼續閱讀Javascript之前閱讀一些教程;否則你很可能會遇到一些真正的問題...
