What is the way to utilize JavaScript for parsing Ruby JSON strings?

I am currently attempting to extract the JSON object from a string that has been outputted in JSON format from a Rails application. In my JavaScript code, I have the following:

data = "<%= @chromosomes.html_safe %>";

The issue I am facing is that due to the presence of quotes at the beginning and end of the JSON object, it is not being recognized as a valid JSON object. This results in something like:

 data = "[{"name":"YHet","organism_id":"4ea9b90e859723d3f7000037"}]"

Is there a method I can utilize to eliminate the leading and trailing quotes so that the object is treated as an array rather than a string?

Answer №1

Have you considered trying this:

collection = <%= @chromosomes.html_safe %>;

Just a thought:

Maybe you could try something similar to:

@chromosomes = [{ label: "YHet", organism_id: "foo" }].to_json

Answer №2

For those utilizing jQuery, the code snippet below can be used

var info = jQuery.parseJSON('[{"title":"Books","category_id":"4ea9b90e859723d3f7000037"}]');

Answer №3

To utilize the JSON object already present in many browsers, or if you're utilizing jQuery, employ the $.jsonParse method. This method will attempt to use the browser's built-in JSON object and fallback to parsing with eval or a more secure approach if necessary.

Answer №4

Working with controller logic

@data = MyModel.find_by_id(10).to_json

Displayed on the webpage using Haml syntax.

var parsed_data = $.parseJSON("#{j @data}"); //Utilizing JQuery to parse JSON data

Answer №5

Try using the eval function:

let objectData = eval('(' + stringData + ')');
