when phone call html contains javascript returns:

undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined,

how should iterate through children label?

my javascript follows:

<script type='text/javascript'> $(document).ready(function(){ console.log('entra...'); $.getjson('arbolcategorias.php', function(data) { //console.log('data ...' + data); $.each(data.children, function(key, val) { if (data.children.has(children)){ $.each(children.children, function(key, val){ $('#jsonresult').append('<li id="' + key + '">' + val.category_id + ', ' + val.parent_id + ', ' + val.name + ', ' + val.is_active + ', ' + val.position + ', ' + val.level + ', ' + val.children + ', ' + '</li>'); }); } else{ $('#jsonresult').append('<li id="' + key + '">' + val.category_id + ', ' + val.parent_id + ', ' + val.name + ', ' + val.is_active + ', ' + val.position + ', ' + val.level + ', ' + val.children + ', ' + '</li>'); } }); }); });

hope can help me guys :d

try data.children within each().

$(document).ready(function(){ console.log('entra...'); $.getjson('arbolcategorias.php', function(data) { console.log('data ...' + data); $.each(data.children, function(key, val) { $('#jsonresult').append('<li id="' + key + '">' + val.category_id + ', ' + val.parent_id + ', ' + val.name + ', ' + val.is_active + ', ' + val.position + ', ' + val.level + ', ' + val.children + ', ' + '</li>'); }); }); });

if utilize $.each(data, ... iterating on object , need iterate on children list

this code using recursive function writechildrens:

function writechildrens(element){ $.each(element.children, function(key, val) { $('#jsonresult').append('<li id="' + key + '">' + val.category_id + ', ' + val.parent_id + ', ' + val.name + ', ' + val.is_active + ', ' + val.position + ', ' + val.level + '</li>'); if(val.children.length>0) writechildrens(val); }); } $(document).ready(function(){ console.log('entra...'); $.getjson('arbolcategorias.php', function(data) { console.log('data ...' + data); writechildrens(data); }); });

javascript php jquery json
