如何使用字符串中的數據更新JavaScript對象？

Question

我有以下數據數組：

var ans = 
[ 
{"text":"x","response":false}, 
{"text":"y","response":false}, 
{"text":"z","response":true} 
]; 

var correct = "010"; // I need to add this to the array ans 

任何人都可以建議我如何使用使用的數據在正確的變量添加到陣列中，使：

var ans = 
[ 
{"text":"x","response":false,"correct":false}, 
{"text":"y","response":false,"correct":true}, 
{"text":"z","response":true,"correct":false} 
]; 

Answer 1

for(var i=0; i< ans.length; i++) { 
    ans[i].correct = correct.charAt(i) == "1"; 
} 

Answer 2

for (var i = 0; i < correct.length; i++) { 
    ans[i]["correct"] = correct[i] === "1"; 
} 

Answer 3

你也是這樣做的（使用for-in循環）。

參考：For-each over an array in JavaScript?

for(key in ans){ 
    ans[key].correct = correct.charAt(key) == "1"; 
} 

Answer 4

var ans = 
    [ 
    {"text":"x","response":false}, 
    {"text":"y","response":false}, 
    {"text":"z","response":true} 
    ]; 

var correct = "010"; 

var sep = correct.split(""); 

var arr = []; 

for (var i = 0; i < sep.length; i++) { 
    if (sep[i] == 0) { 
     arr.push("false"); 
     } else { 
     arr.push("true"); 
    } 
    } 

    var len = ans.length; 

for (var i = 0; i < len; i++) { 

     ans[i].correct = arr[i]; 
    }
