Generate unordered list from JSON Data?

Question

I\'d like to generate a tree view of my JSON data. Therefore it would be nice to parse the JSON data into a multi-level (!) unordered HTML list

Answer 1

Just a quick simple example:

function tree(data) {    
    if (typeof(data) == 'object') {
        document.write('
');
        for (var i in data) {
            document.write('
' + i);
            tree(data[i]);            
        }
        document.write('
');
    } else {
        document.write(' => ' + data);
    }
}

jQuery version:

function tree(data) {    
    if (typeof(data) == 'object') {        
        var ul = $('
');
        for (var i in data) {            
            ul.append($('
').text(i).append(tree(data[i])));         
        }        
        return ul;
    } else {       
        var textNode = document.createTextNode(' => ' + data);
        return textNode;
    }
}

$(document.body).append(tree(data));
