Make var available to a inline function in javascript

Question

I'd like to create that function :

generateJson = function()
{
    var controls = {
        "invoicedate" : "invoicedate",
        "duedate" : "duedate"
    };

    var jsonLog = {};

    $.each(controls, function(index, value, jsonLog) {
      jsonLog[value] = "t";
    });
    $('#jsoncode').val(JSON.stringify(jsonLog));
}

I have an error : Uncaught TypeError: Cannot set property 'invoicedate' of undefined

How can I make the jsonLog var available in my inline function ?

Regards

Remove the third argument from the function you pass to each since:

The each won't pass anything into it
It masks the variable of the same name in the wider scope that you assigned the object to

passing jsonLog as third argument is overriding or masking the previous actual jsonLog in parent scope

$.each(controls, function(index, value) {
      jsonLog[value] = "t";
    });
