Question

I have the following code where I am setting some arbitrary data on a li element

function showCountries( data )
{
    for( var i in data )
    {
        var li = document.createElement('li');
        $(li).html( '<a>' + i + '</a><span>&gt;</span>' );
        $(li).data('cargo', { state: data[i] });
        /* 
           right here, if I look at $(li).data('cargo').state in the debugger
           I see the data as expected
        */
        $('#countries').append( li );
        $(li).on('click', $.proxy( countrySelected, li ) );
    }
}

Later, in country selected, I want to get the cargo data. But, it is undefined

function countrySelected()
{
    var country = $(this).children('a').html();
    // country is what I expect

    var cargo = $(this).children('a').data('cargo');
    // cargo is undefined here

    // I tried this too:
    var cargo = $('#countries li.selected a').data('cargo');
    // cargo is undefined here as well
}

What I am doing wrong? Is this an issue with the .data() being set dynamically after the page is loaded?

Thanks,
Scott

Answer 1

This line:

var cargo = $(this).children('a').data('cargo');

should be changed to this:

var cargo = $(this).data('cargo');

You set the data in the li element, not in the child a.
