Looping through a JSON array and replacing the values if they are NULL

Question

I have an array of JSON coming from my controller

<%= raw @visits %>

I simply want to loop through this, and if the "name" is null then replace it with the string "Unknown". Currently this fails.

var withNull = <%= raw @visits %>;

var noNull = $.each(withNull, function(obj) {
    if(obj.name ==  null) {
        obj.name = "Unknown";
    }
});

Answer 1

Use

$.each(withNull, function(idx, obj) {

The parameters to jQuery's $.each callback are in "backward" order. It passes the index first, then the element.

Prefer to use

withNull.forEach(function(obj) {
