我尝试通过扫描条形码将产品添加到购物车。 在 common.js 中我添加了
$('body').on('keydown', '#form-for-saler-add-to-cart', function(e) { if (e.keyCode == 13) { function getIdByEan(ean) { $.ajax({ type: "POST", url: 'index.php?route=checkout/cart/getIdByEan', data: ean, success: function(data) { // Run the code here that needs // to access the data returned return data; } }); } idbyean = getIdByEan($(this).val()); console.log($(this).val()); console.log(idbyean); cart.add(idbyean); // cart.add($(this).val()); $(this).val(''); $(this).html(''); } });
在controller/checkout/cart.php中添加功能:
public function getIdByEan() { $this->load->model('catalog/product'); if (isset($this->request->post['ean'])) { $product_id = (int)$this->model_catalog_product->productIDByEan($this->request->post['ean']); } else { $product_id = 0; } $this->request->post['product_id'] = $product_id; }
以及 model/catalog/product.php
public function productIDByEan($ean) { $query = $this->db->query("select product_id from " . DB_PREFIX . "product where ean = '" . $this->db->escape($ean) . "'"); return $query->row['product_id']; }
但我得到 idbyean 为未定义。我做错了什么?
我已经解决了。在common.js中
在控制器/checkout/cart.php
在 model/catalog/product.php
