JQuery - SyntaxError:保留字"this"无法分配

Question

我正在尝试在JQuery中循环变量并重新分配this以下Coffeescript中的值.

$.each data.rows, ->
  completion_time = [this[0], new Date(new Date('Jan 01 2000').getTime() +  this[1])]
  this = completion_time

但是,这会产生以下错误消息:

SyntaxError:无法分配保留字"this"

在每次迭代中,值this看起来像这样:

["abc123",12302103,1230132,1230123]

我要做的是将其重新分配给以下值:

["abc123",12302103]

我也尝试过分配this.value,没有骰子.有什么建议？

Answer 1

You can't reassign this. You can modify this to contain the elements in the new array

I can't stand CoffeScript, so I'll just show it in JS

// Clear elements from the array
this.length = 0;
// Add each element in the new array
this.push.apply(this, completion_time);
