Question

我有一个JSON数组（对象），我想通过它来导航并获得它的值。但我得到了：＆＃34; Uncaught TypeError：无法读取属性＆＃39;长度＆＃39;未定义＆＃34;。

这是生成JSON的ajax函数：

$.ajax({
  type: 'GET',
  url: "<?php echo $html->url(array("controller" => "porders", "action" => "getBudgetProduct")); ?>",
  data: "product_id="+product_id+"&cantidad="+cantidad,
  dataType:"text json",
  success: function(producto){
    console.log(producto);
    addCost(producto, cantidad);

  },
  error: function() {
    console.log("Error en el AJAX");
  }
});

这是数组：

[
    {
        "Motion": {
            "id": "1801",
            "code": "31042014",

        }
    }

我有一个html视图，我想在表中显示数组的值。我是这样做的。（addCost（）函数代码）：

function addCost(producto, cantidad)
{
    var html = '';
                html += '<h2>';
                html += '<?php  __("Costo de Producción");?>';
                html += '</h2>';
                html += '<h3>';
                html += '<?php  __("Lista de Semiterminados");?>';
                html += '</h3>';
                html += '<table id="items" cellpadding="0" cellspacing="0" style="width:500px;">'
                html += '<tr>';
                html +=     '<th><?php __("Codigo"); ?></th>';
                html +=     '<th><?php __("Codigo Secundario"); ?></th>';
                html +=     '<th><?php __("Producto"); ?></th>';
                html +=     '<th><?php __("Cantidad"); ?></th>';
                html += '</tr>';
                for (var i = 0; i < producto.length; i++) {
                    if (producto[i]["Motion"]["composers"] > 0) 
                    {
                        html += '<tr>';
                        html +=     '<td class="code">';
                        html +=         '<input type="hidden" value="" class="id">';
                        html +=         producto[i]["Motion"]["code"];
                        html +=         '&nbsp;';
                        html +=     '</td>';
                        html +=     '<td class="code2">';
                        html +=         producto[i]["Motion"]["code2"];
                        html +=         '&nbsp;';
                        html +=     '</td>';
                        html +=     '<td class="name">';
                        html +=         producto[i]["Motion"]["name"];
                        html +=         '&nbsp;';
                        html +=     '</td>';
                        html +=     '<td class="quantity">';
                        html +=         producto[i]["Motion"]["quantity"];
                        html +=         '&nbsp;';
                        html +=     '</td>';
                        html += '</tr>';    
                    };
                };
                html += '</table>';
);

这是显示调试器的错误：

第一个console.log它是返回的json的console.log（），名为producto

请你帮忙。感谢

我把Javascript和你的html在Jsfiddle上正常工作了。 Link to working code

所以我认为还有其他的东西，我想有些变量是未定义的。

迭代这个JSON对象并获得它的值？
