Convert JSON object to a string representation

Question

Convert JSON object to a string representation

I am attempting to print a JSON object in string format.

(I actually retrieved these data values from Ruby code

var data = '<%=[@pro {|c| {x:c.x, y:c.y}}].to_json%>'

)

When printing the data variable, I noticed that the values contain &quot instead of '

var data=[[{&quot;x&quot;:1,&quot;y&quot;:0}]]

I would like to have the values in the format

var data="[[{ 'x': '1', 'y': '0' }]]";

After removing " using the code

var dataset=JSON.parse(data.replace(/&quot;/g,'"'));

, the output is as follows:

var dataset =[[{"x":1,"y":0}]]

I want to display the values like [[{ 'x': '1', 'y': '0' }]]. How can this be achieved?

If you only have 2 variables, you can easily achieve this by following these steps:

var data = [[{'x': '<%= @pro.x %>', 'y': '<%= @pro.y %>'}]];

No need to complicate things with the to_json method.

However, if you have multiple values that need to be stringified, you can use the following code snippet:

<% array = [[{'x' => 1, 'y' => 1}], [{'x' => 2, 'y' => 2}], [{'x' => 3, 'y' => 3}]] %>
<%= array.to_json %>

When executed, it will produce the following output:

[[{"x":1,"y":1}],[{"x":2,"y":2}],[{"x":3,"y":3}]]

If you need to send JSON through a request in your controller, you can utilize the following code block:

def send_json_array
    array = [[{'x' => 1, 'y' => 1}], [{'x' => 2, 'y' => 2}], [{'x' => 3, 'y' => 3}]]
    response.headers['Content-type'] = "text/plain; charset=utf-8"
    render :text => array.to_json
end

When using JSON.stringify, an object can be converted into its corresponding JSON representation.

let dataPoints = [{"x":1,"y":0}]
let jsonData = JSON.stringify(dataPoints);
