如何在列表框中打开网页地址 [英] how do i open web page address in listbox

问题描述

我有一个文本框，列表框和两个按钮.

当我单击button1时，我们输入的网址将移动到列表框.
为此，只需在列表框中添加多个网址即可.
现在，当我单击第二个按钮时，列表框中的地址会在多个新窗口中打开.
我的代码是

i m having one text box,list box and two button.

when i click button1 the webaddress which we entered is moved to listbox.
like that by adding more than one webaddress to list box.
now when i click second button the address in list box open in multiple new window.
my code is

<table>
  <tr>
  <td>
  <asp:TextBox ID="txtMail" runat="server"></asp:TextBox>
  </td>
  <td>
  <asp:ListBox ID="List" runat="server"></asp:ListBox>
  <a href="Default.aspx" runat="server"></a>
  </td>
  </tr>
  <tr>
  <td colspan="2" align="center">
      <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
  <asp:Button ID="btnClick" Text="Click" runat="server" onclick="btnClick_Click" />
  </td>
  </tr>
  </table>

在后面的代码中

in code behind

protected void Button1_Click(object sender, EventArgs e)
    {
        List.Items.Add(txtMail.Text);

    }

protected void btnClick_Click(object sender, EventArgs e)
    {
what can i do here
    }

通过使用javascript手段，告诉我代码

by using javascript means tell me the code

推荐答案

使用anchor标签的target属性可以实现以下目的:

Use the target attribute of the anchor tag to achieve that:

<a target="_blank" href="http://www.google.com">Go and google it!</a>

这就是全部！

我不确定您的问题，但这是我的解决方法

I am not sure about your question, but here is my solution

//Javascript
<script>
    function openItem(ctrl)
    {
        window.open(ctrl.value);
    }
</script>
//ASPX
 <asp:listbox id="ListBox1" runat="server" onclick="openWebSite(this)" xmlns:asp="#unknown">
            <asp:listitem text="http://www.google.com"></asp:listitem>
            <asp:listitem text="http://www.yahoo.com"></asp:listitem>
        </asp:listbox>
