Question

I’m trying to loop through a variable in JQuery and reassign the value of this in the following Coffeescript.

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

However this produces the following error message:

SyntaxError: reserved word “this” can’t be assigned

On each iteration the value of this looks something like this:

[“abc123”, 12302103, 1230132, 1230123]

What I’m trying to do is reassign it to the value of:

[“abc123”, 12302103]

I tried assigning this.value as well, no dice. Any suggestions?

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);
