Question

我正在试图获得以下产品的价格 http://www.newegg.com/Product/Product.aspx?Item=N82E16822236715

仅使用jQuery，以下代码正常工作，并在预处理之前为我提供了值

 java.text.ParseException: Unparseable date: "Mon Nov 23 2015 08:00:00" (at offset 0)

我正在尝试使用Goutte和Laravel来做同样的事情：

jQuery('.grpPrimary div[style = "display: block;"] .price-current').text()

我没有得到价格值，我试图选择它的父div，但价格值没有在任何一个中显示。它与phpquery一样。

Answer 1

我不认为这是一个很好的方法，只需通过探索返回的HTML，我已经看到有这个小JS：

  var utag_data = {
  page_breadcrumb:'Home &gt; Components &gt; Hard Drives &gt; Desktop External Hard Drives &gt; Western Digital &gt; Item#:9SIA29P2YK5768',
        page_tab_name:'Components',
        product_category_id:['15'],
        product_category_name:['Hard Drives'],
        product_subcategory_id:['414'],
        product_subcategory_name:['Desktop External Hard Drives'],
        product_id:['9SIA29P2YK5768'],
        product_web_id:['9SIA29P2YK5768'],
        product_title:['WD Elements 2TB USB 3.0 External Desktop Storage WDBWLG0020HBK-NESN Black'],
        product_manufacture:['Western Digital'],
        product_unit_price:['89.99'],
        product_sale_price:['79.99'],
        product_default_shipping_cost:['0.01'],
        product_type:['Seller'],
        product_model:['WDBWLG0020HBK-NESN'],
        product_instock:['1'],
        product_group_id:['30896206'],
        hl_seller_id_list:'A29P|A4P0|1|A6ZP|A2F8|A1N8|A24G|A0ZX|A8H5|A6AH',
        hl_prod_id_list:'9SIA29P2YK5768|9SIA4P02RJ6296|N82E16822236715|9SIA6ZP3K22742|9SIA2F83426160|9SIA1N81YB4387|9SIA24G2179173|9SIA0ZX1W07804|9SIA8H531C6923|9SIA6AH3AB2901',
        hl_prod_p_list:'79.99|89.99|94.99|106.62|109.35|110.29|109.59|113.93|131.86|131.69',
        hl_prod_qty_list:'1|1|1|1|1|1|1|1|1|1',
        parent_item:'N82E16822236715',
        page_type:'Product',
        site_region:'USA',
        site_currency:'USD',
        page_name:'ProductDetail',
        search_scope:jQuery('#haQuickSearchStore option:selected').text(),
        user_nvtc:Web.StateManager.Cookies.get(Web.StateManager.Cookies.Name.NVTC),
        user_name:Web.StateManager.Cookies.get(Web.StateManager.Cookies.Name.LOGIN,'LOGINID6'),
        third_party_render:['4774d6780334a7bf9c3c95255c60401916d07cae','78b8b16d9d0f6f2e8419ac12fa710f5153f1cee3','65531e14b4d9b9a223cc3bfcb65ce7b5f356011d','2a5e772a0f941c862180037f8a5c118c7abf2f7d','9011adc5233493f5adc5f0f0f1bcb655892c09e3']

  };

所以，如果我是你，我会做一个正则表达式，它会在[\d.]+（product_sale_price:['）和product_sale_price:\['之间取每个数字和点（']）{{{ 1}}）

所以它是这样的：

'\]

所以在PHP中它将是：

product_sale_price:\['([\d.]+)'\]

因此，您的结果将存储在$str = '...'; // The JS array OR the full HTML page will also work preg_match("/product_sale_price:\['([\d.]+)'\]/", $str, $matches);数组中;所以：

$matches
