ecshop增加购买直接进入购物车与默认购物流程并存

ecshop如何设置了购买停留在商品页面之后,将ecshop商品加入购物车的时候,就不会直接进入购物车,这样使用购物车非常不方便,我们为了既保持该页面功能,又能进入购物车功能,所以增加了另外一个购买按扭,点购买之后,可以直接进入ecshop的购物车,这样只牵涉到修改ecshop模板,对ecshop二次开发稍微修改就可以做到.

1:goods.dwt模板

2:js/common.js

function addToCart1(goodsId, parentId)

{

  var goods        = new Object();

  var spec_arr     = new Array();

  var fittings_arr = new Array();

  var number       = 1;

  var formBuy      = document.forms['ECS_FORMBUY'];

  var quick     = 0;

  // 检查是否有商品规格

  if (formBuy)

  {

    spec_arr = getSelectedAttributes(formBuy);

    if (formBuy.elements['number'])

    {

      number = formBuy.elements['number'].value;

    }

quick = 1;

  }

  goods.quick    = quick;

  goods.spec     = spec_arr;

  goods.goods_id = goodsId;

  goods.number   = number;

  goods.parent   = (typeof(parentId) == "undefined") ? 0 : parseInt(parentId);

  Ajax.call('flow.php?step=add_to_cart1', 'goods=' + goods.toJSONString(), addToCartResponse1, 'POST', 'JSON');

}

function addToCartResponse1(result)

{

  if (result.error > 0)

  {

    // 如果需要缺货登记，跳转

    if (result.error == 2)

    {

      if (confirm(result.message))

      {

        location.href = 'user.php?act=add_booking&id=' + result.goods_id + '&spec=' + result.product_spec;

      }

    }

    // 没选规格，弹出属性选择框

    else if (result.error == 6)

    {

      openSpeDiv(result.message, result.goods_id, result.parent);

    }

    else

    }

  }
