无论如何，有没有更新HTML内定义的现有数组？

Question

有一个静态数组，应该根据click事件动态更新。

我能够使用Ajax以数组格式获取动态值，但是很难将其设置为现有变量。

Ajax返回以下数组

echo json_encode($arry);
// ["2","1","1","0","1","0"]

$.post( "ajaxcall.php", { ids: id })
   .done(function( returnedArray){
      //returnedArray looks like ["2","1","1","0","1","0"]
      datasets: [{
                  //data: [10,12,33,50,12,34]
                  data: returnedArray
                 }]
     },

但是在单击事件之后，不会解释returnArray来放置值。

基本上，结果应如下所示：

data: ["2","1","1","0","1","0"]

Answer 1

使用赋值运算符代替:

datasets = [{
     //data: [10,12,33,50,12,34]
     data: returnedArray
}]
