如何使用图像按钮，在另一个窗口中打开URL

问题描述

您好我知道如何在超链接设置目标达致这= _blank，我怎么能做到这一点使用图像按钮控制，下面是我的code：

 ＆LT; ASP：ImageButton的的OnClick =test_Click的ImageUrl =/图像/联系我们/ directionbtn.pngID =测试=服务器的ValidationGroup =组2/ ＆GT;             ＆LT; ASP：的RequiredFieldValidator ID =RequiredFieldValidator2=服务器
            的ControlToValidate =txtPost code1的ErrorMessage =邮报code需要的ValidationGroup =组2＆GT;＆LT; / ASP：＆的RequiredFieldValidator GT;
            ＆LT; BR /＆GT;
 

背后code：

 保护无效test_Click（对象发件人，ImageClickEventArgs E）
{    Response.Redirect(String.Format(\"http://maps.google.co.uk/maps?saddr={0}&daddr=&daddr=Wigan+WN6+0HS,+United+Kingdom&iwloc=1&dq=Tangent+Design\", txtPost code1.Text））;}
 

任何帮助或建议将pciated高度AP $ P $

解决方案

 保护无效的Page_Load（）{
   ControlID.Attributes.Add（目标，_blank）;
}
 

如果不工作，你可以添加以下到您的ImageButton：

 ＆LT; ASP：ImageButton的=服务器的OnClientClick =window.open（'的http：// URL /到/开'）;
 

Hi I know how to acheive this in hyperlink by setting target = _blank , how can i do this using image button control , below is my code:

<asp:ImageButton OnClick="test_Click" ImageUrl="/images/contactUs/directionbtn.png" ID="test" runat="server" ValidationGroup="group2" />

             <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
            ControlToValidate="txtPostcode1" ErrorMessage="Postcode is required"  ValidationGroup="group2"></asp:RequiredFieldValidator>
            <br />

Code behind:

    protected void test_Click(object sender, ImageClickEventArgs e)
{

    Response.Redirect(String.Format("http://maps.google.co.uk/maps?saddr={0}&daddr=&daddr=Wigan+WN6+0HS,+United+Kingdom&iwloc=1&dq=Tangent+Design", txtPostcode1.Text));



}

Any help or advice will be highly appreciated

解决方案

protected void Page_Load() {
   ControlID.Attributes.Add("target", "_blank");
}

If that doesn't work, try adding this to your ImageButton:

<asp:ImageButton runat="server" OnClientClick="window.open('http://url/to/open');
