Get JSON Object by string

Question

I wrote a function which take an id of the link as a name of JSON dataset.

$('.link').click(function() {
    var dataset = $(this).attr("id");
    for (var i = 0; i < chart.series.length; i++) {
        chart.series[i].setData(lata.dataset[i].data);
    }
});

But in this case dataset is string and it doesn't works. So how to get object from JSON file by string?

how big is this JSON data set that you are storing in the id? — Tim B James

Use the [] operator:

chart.series[i].setData(lata[dataset][i].data);

foo['bar'] and foo.bar are equivalent - except the fact that [] takes an expression and thus allows you to use e.g. a variable.

chart.series[i].setData(lata[dataset][i].data);

this would be valid even if dataset is nto a valid identifier like "a b"
