我是rails的新手,我收到了一个错误,我似乎无法找到问题所在.这是日志:

每当我去文件找到那一行时,就没有了each,我无法理解问题出在哪里.有人可以帮忙吗？不仅仅是修复,我想了解这个问题.

这是文件:

class Lifetime
  attr_reader :values

  GROWTH_CUT_OFF = 0.10

  def initialize(engaged_users_values)
    @values = engaged_users_values
  end …

我有这些我需要循环的脚本:

$(document).ready(function() {
    runIt();
})
function resets()
{
  $('.grower').removeAttr("style");
}

function runIt() 
    {
        $('.grower').animate({width: "30px",height: '30px', left: "-6", top: "-6", opacity:"0"}, 800, resets);
    }

但是当我添加runIt(); 在它自己内部所以它可以循环,它循环但我的浏览器空白,我不会回应.我该怎么做才能循环播放动画.

提前致谢

我对数组的键有一点问题.该数组如下所示:

Array
(
    [1] => Array
        (
            ["question"] => test question 1
            ["open_response"] => 1
        )

    [2] => Array
        (
            ["question"] => test question 2
            ["yes_no"] => 1
        )

)

但出于某种原因,每当我尝试访问$data['1']['question']它时,告诉我问题不是索引.我对此有点困惑,因为它应该是关键但不是,我该如何解决这个问题？或者我如何访问它？
