推荐答案

如果你只是定义A和B，你可以立即在JavaScript中使用它：

If you simply define A and B, you could use it in JavaScript immediately:

var A, B
var array = [[A,150,500,6000],[B,160,700,7000],[B,200,633,9000],[B,210,633,9000]]
// now you can access members directly:
var second = array[1]; // returns [B,160,700,7000]
var element = array[1][1]; // returns first number, 140

或者，您可以解析字符串，依此类推，但您只需将其用作 eval 调用的参数，并执行以上所有操作。

Alternatively, you can parse string, and so on, but you can simply use it as the argument of the call to eval and do all of the above.
