Question

我尝试了很多方法都行不通你有什么解决方案吗？

<button type="button" class="btn btn-solid-primary btn--l _3Kiuzg" aria-disabled="false">buy</button>

我的代码和错误

browser.find_elements_by_css_selector(".btn-solid-primary").click()

AttributeError: 'list' object has no attribute 'click'

我可以试试

find_elements_by_class_name

不工作

browser.find_element_by_class_name("btn btn-solid-primary btn--l _3Kiuzg")

错误

这是答案 - 在下面的代码中将元素更改为元素。

 public void BindAllCartnulluser()
        {
            string GuestID = Request.QueryString["guestid"];
            try
            {
                SqlConnection con = new SqlConnection(CS);
                SqlCommand cmd = new SqlCommand("ProcDataBind_SelectCartGuest", con);
                cmd.CommandType = CommandType.StoredProcedure;
                con.Open();
                cmd.Parameters.AddWithValue("@guestid", GuestID);

                DataSet ds = new DataSet();
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                da.Fill(ds);
                dtlistgrid.DataSource = ds;
                dtlistgrid.DataBind();

                decimal sum = 0; decimal qty = 0;
                for (int i = 0; i < dtlistgrid.Items.Count; i++)
                {
                    sum += Convert.ToDecimal(((Label)dtlistgrid.Items[i].FindControl("totalpricelbl")).Text);
                    qty += Convert.ToDecimal(((Label)dtlistgrid.Items[i].FindControl("qtylbl")).Text);
                }

                lblsubTotal.Text = sum.ToString();
                lbltotal.Text = sum.ToString();
                lblTotalQty.Text = qty.ToString();

                con.Close();
            }
            catch
            {

            }
        }

此外，我假设您正在解析 Instagram。它使用动态类（在您的情况下，_3Kiuzg），在页面重新加载后会发生变化。所以请确保，您不是在寻找元素。函数 find_element_by_class_name 没有带很多类，所以，如果你想要这样，你应该使用 find_element_by_css_selector 和选择器 .class_1.class_2.etc
