从哈希中取出值并插入到ruby中的数组中

Question

I am having

students = {1=>"alexandar", 2=>"mona", 3=>"gaga", 4=>"", 5=>"tom", 35=>"abcd", 44=>"hin"}
array = []

I had given this

array = students.values

and when I write in my test.js.erb

$('.show-test').text('<%= array%>')

it gives o/p

["alexandar", "mona", "gaga",
"tom", "abcd", "hin"]

Now I need to show text like this

 [alexander, mona, gaga, tom, abcd, hin]

Please guide me how to solve this. Thanks in advance

Answer 1

Super simple, use Hash#values :

$> students = {1=>"alexandar", 2=>"mona", 3=>"gaga", 4=>"", 5=>..............}
$> students.values # <- Array with values
=> ["alexandar", "mona", "gaga", "", "tom", "abcd", "hin"]

Update:

Use html_safe if you trying to render json from controller.

$('.show-test').text('<%= array.html_safe %>') 

or:

$('.show-test').text('<%= array.to_json.html_safe %>')

or (the same thing as html_safe ):

$('.show-test').text('<%= raw(array.to_json) %>')
