Question

在我的网站中，当我点击提交按钮时，它应该显示文本框中的所有链接，但是我的提交按钮不起作用，当我点击它时会发生这种情况。这是我的代码。我的提交按钮具有onclient点击属性。

        protected void btnRender_Click(object sender, EventArgs e)
        {
            string strResult = string.Empty;

            WebResponse objResponse;
            WebRequest objRequest = System.Net.HttpWebRequest.Create(url.Text);

            objResponse = objRequest.GetResponse();

            using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()))
            {
                strResult = sr.ReadToEnd();
                sr.Close();
            }
            strResult = strResult.Replace("<form id='form1' method='post' action=''>", "");
            strResult = strResult.Replace("</form>", "");
            //strResult = strResult.Replace("<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" /><html xmlns="http://www.w3.org/1999/xhtml">");
            div.InnerHtml = strResult;

        }

        protected void btn_createlink_Click(object sender, EventArgs e)
        {
            var links = TextBox1.Text.Split(new string[] { "\n", "\r" }, StringSplitOptions.RemoveEmptyEntries);
            foreach (var link in links)
            {
                if (!IsLinkWorking(link))
                {
                    //Here you can show the error. You don't specify how you want to show it.
                    TextBox2.Text += string.Format("{0}\nNot working\n\n ", link);
                }
                else
                {
                    TextBox2.Text += string.Format("{0}\n working\n\n", link);
                }
            }
        }


        bool IsLinkWorking(string url)
        {
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);

            //You can set some parameters in the "request" object...
            request.AllowAutoRedirect = true;
            ServicePointManager.ServerCertificateValidationCallback = (s, cert, chain, ssl) => true;

            try
            {
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                return true;
            }
            catch
            {
                //TODO: Check for the right exception here
                return false;
            }
        }


        protected void Button1_Click(object sender, EventArgs e)
        {
            TextBox1.Text = "";
            TextBox2.Text = "";
            url.Text = "";
        }

    }

这是我的客户端代码在这里，我有一个名为finda（）的函数。当客户点击提交按钮时，它应该调用，但这不会发生

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> 

    <script type="text/javascript">
        function finda() {
            var a = document.getElementsByTagName("a");
            var b = document.getElementById("TextBox1");
            b.value = "";


            for (var i = 0; i < a.length; i++) {
                a[i] = a.length.value;


                if (a[i] == null) {
                    alert("Their is no links");
                }
                else {
                    b.value = b.value + "\r\n\n" + a[i];
                }

            }

            //            window.open("http://www.fillsim.com");
            window.close();
            //   window.open("WebForm3.aspx?req=" + b.value);


        }
    </script>
   <script type = "text/javascript">
       var defaultText = "http://www.example.com";
       function waterMarkText(txt, evt) {
           if (txt.value.length == 0 && evt.type == "blur") {
               txt.style.color = "red";
               txt.value = defaultText;
           }
           if (txt.value == defaultText && evt.type == "focus") {
               txt.style.color = "green";
               txt.value = "";
           }
       }
</script>
</asp:Content>

Answer 1

您的form标记应具有runat="server"属性，以便可以正确处理ASP.NET回发事件。

当我点击提交按钮时，不会调用任何功能
