Replace null values to empty values in a JSON OBJECT

Question

Hi I\'ve got a JSON object provided by an ajax request.

Some of the values inside the json appears as null, but I want an empty String inst

Answer 1

I recommend you the check the return type of the Ajax because it determines how to remove null.

If it is string, you can use this:

data = data.replace(/null/g, '""');  //Stays as string

Or:

data = JSON.parse(data);    // Turns to a JSON object

If it is json object, then you can use this:

data = JSON.stringify(data).replace(/null/g, '""');  //Turns to string
