Use like this

(function filter(obj) {
    $.each(obj, function(key, value){
        if (value === "" || value === null){
            delete obj[key];
        } else if (Object.prototype.toString.call(value) === '[object Object]') {
            filter(value);
        } else if ($.isArray(value)) {
            $.each(value, function (k,v) { filter(v); });
        }
    });
})(sjonObj);

You should use array access notation please see the below code

    delete sjonObj[key];


 $.each(sjonObj, function(key, value){
 if (value === "" || value === null){
    delete sjonObj[key];
  }
 });

Thanks
