Display JSON on the screen so it can be easily copied and pasted

I have a unique challenge where I need to output some Javascript code on the browser screen for easy transfer to another program.

Currently, I am utilizing JSON.stringify() from the json2.js library. However, this method is not correctly escaping characters such as quotes and new lines (",\n) which are crucial parts of a JSON object.

An issue arises when importing into another program due to problematic strings like the following:

{
    string_property_01 : "He said "HI"";  // The string terminates after "He said "
}

Does anyone know of any libraries that can efficiently escape all necessary characters in this scenario?

Thank you!

Choice #2 

var obj = {
    func2 : function (info) {
        var infoText = JSON.stringify(info);
        // using jquery
        $('#debugArea').text(infoText);
    }
}

// example of usage
obj.func2({ id: "4", name: "John Smith" });

In HTML: 

<textarea id='debugArea' rows='10' cols='50'></textarea>

Answer №2

Check out this fantastic trick I use:

let h = {
    customMethod : function (info) {
        let infoAsString = JSON.stringify(info);
        let result = prompt('Feel free to copy and paste this', infoAsString);
    }
}

// To use this method...
h.customMethod({ id: "7", name: "Emily Davis" });

Isn't the JavaScript prompt amazing?

Answer №3

Have you considered if this could be a result of the browser's rendering and not an actual issue with the JSON library? It's important to ensure that the characters are properly escaped in order to generate a valid JSON string. If necessary, try comparing the output of json2.js with the native JSON.stringify function available in certain browsers such as Chrome.
