Escape String - Output rails string in Javascript [duplicate]

Question

I'm trying to assign a string value to a javascript object in my .erb file like so:

var data = {
    'name': '<%= @product.name %>',
    ...
};

The problem is, if the value of name is Tom's small ears,

the output of data.name would be Tom's small ears.

Is there a way to escape special characters?

I tried doing 'name': '<%= raw @product.name %>' but Uncaught SyntaxError: Unexpected identifier gets output into the console.

Doing <%= escape_javascript @product.name %> outputs Tom\'s small ears

Edit @Stefan's comment under MrYoshiji's answer worked for me.

You can use escape_javascript() to accomplish that:

var data = {
    'name': "<%== escape_javascript @product.name %>",
    #...
};

Link: http://api.rubyonrails.org/classes/ActionView/Helpers/JavaScriptHelper.html#method-i-escape_javascript

The alias of this method is j:

 var data = {
     'name': "<%== j @product.name %>"
 }
