在JavaScript控制台中打印数组时，请删除“

Question

I have an array that I am passing to a javascript file.

In the controller I have the array printing out and it appears like so...

["123456789", "987654321", "147852369", "369852147"]

This array is set to the instance variable @array in the controller.

I'm sending this array to a JavaScript file by setting @array as a variable in the view.

var array = "<%= @array %>";

Note: I've tried var array = "<%=raw @array.to_json %>"; as well.

Then in the JavaScript file I am simply printing the array in the console like so...

console.log(array);

However when it is printed in the console the output looks like this.

["123456789", "987654321", "147852369", "369852147"]

When I check the typeof through jQuery it comes back as a string instead of an array.

I do not want to see the " . Eventually I want to use these values as selectors when running some JavaScript functions.

Through these steps, what am I doing wrong that is producing the " ?

edit: This is how I am initially creating my array.

  CONTROLLER
  @original= large_array_of_hashes
  # I am grabbing only specific data from the hash. Only what comes after @errors=>
  @data = @original.scan(/@errors=>"(.*?)"/).flatten.map{ |msg| msg.gsub(/(\.|\s+)/, '').strip }
  @array = []
  @data.each{|data| @array << data}

Answer 1

My issue was corrected by just prepending raw to my ruby variable

<%= raw @array %>

I know it's late but hope it helps someone down the road!

Answer 2

I think that

@array = %w[123456789 987654321 147852369 369852147]

and then your javascript things will work.

Answer 3

TRy this, place them in single quotes

IN javascript

var array = '<%= @array.to_json %>';
array.replace(/&quot;/g, '"');
