javascript - 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 instead

My sample of code :

$.post("/profil_process/wall/preview-post.php",param, function (data){
    // this does not work
    JSON.stringify(data, function(key, value) { return value === "" ? "" : value });
    $('#previewWall').html(getPostWall(data.type,data.titre,data.url,data.description,data.media,data.photo_auteur,data.nom_auteur,data.url_auteur,data.date_publication)).fadeIn();
    $(".bouton-vertM").show();
    $("#wLoader").hide();
},'json');

Any ideas?

Your function should be like this:

function (key, value) {
    return (value === null) ? "" : value;
}

If the value is null, then it returns an empty string.
