Uncaught SyntaxError: Unexpected token for while adding data to pieChart dynamically

Question

我已经破坏了 json 个对象，当我尝试在 PieData 中循环以填充 pieChart 时，我正在为这个错误而苦苦挣扎这是我的代码

  var PieData        = [

       for(b in quizs[i].quests[j].reps){
           //quizs[i].quests[j]["quizId"]
        /*   if(quizs[i].quests[j].reps[b]["stat"]==null){
               var l = 1;
           }
           else{
               var l =quizs[i].quests[j].reps[b]["stat"]
           }*/

           {
          {%set h = 'hex'%}        


    value    : 2,
    startAngle: 240,
    color    : '{{h}}',  
    label    : quizs[i].quests[j].reps[b]["rep"]
  },  }        
       ];

当我尝试更改为静态时 for => for (var r = 0; r < 2; r++) { 我总是遇到同样的错误，感谢任何帮助

不能在数组声明中使用 for。

var PieData = [];
for (var b in quizs[i].quests[j].reps) {
    PieData.push({
        value: 2,
        startAngle: 240,
        color: "{{h}}",
        label: quizs[i].quests[j].reps[b]["rep"]
    });
}

Array#map 这里看起来会更干净

var PieData = quizs[i].quests[j].reps.map(i => ({
    value: 2,
    startAngle: 240,
    color: "{{h}}",
    label: i.rep
}));
