Convert JSON array to an HTML table in jQuery

Question

Is there a really easy way I can take an array of JSON objects and turn it into an HTML table, excluding a few fields? Or am I going to have to do this manually?

Converting a 2D JavaScript array to an HTML table

To turn a 2D JavaScript array into an HTML table, you really need but a little bit of code :

function arrayToTable(tableData) {
    var table = $('');
    $(tableData).each(function (i, rowData) {
        var row = $('');
        $(rowData).each(function (j, cellData) {
            row.append($(''+cellData+''));
        });
        table.append(row);
    });
    return table;
}

$('body').append(arrayToTable([
    ["John","Slegers",34],
    ["Tom","Stevens",25],
    ["An","Davies",28],
    ["Miet","Hansen",42],
    ["Eli","Morris",18]
]));

Loading a JSON file

If you want to load your 2D array from a JSON file, you'll also need a little bit of Ajax code :

$.ajax({
    type: "GET",
    url: "data.json",
    dataType: 'json',
    success: function (data) {
        $('body').append(arrayToTable(data));
    }
});
