动态指定超链接参数的几种方法(Passing a JavaScript variable into href of )

情景：有些环境下我们需要根据页面中JavaScript变量的值来确定某个（某些）超链接的参数，如“http://www.bla.com/test.aspx?var1=”中，究竟var1等于多少，要根据JavaScript变量来判定

方法一：很简单，客户端脚本

function redirectURL(){
    var jsvar1;
    var jsvar2;
    window.location="http://www.bla.com/test.aspx?var1="+jsvar1;//jsvar1为JavaScript变量
    }

方法二：在服务端Load时赋值 The easiest way would be to add the runat="server" property to the anchor and set the href in the CodeBehind

private void Page_Load(object sender, System.EventArgs e)
{
yourAnchor.HRef = redirectURL();
}

private string redirectURL()
{
string jsvar1 = "";
string jsvar2 = "";

return "http://www.bla.com/test.aspx?var1=" + jsvar1;
}

方法三：客户抱怨说页面上这种超链接很多，不适合为每个超链接写一段onclick的Script，想了一下，还有种方法可以使大量动态超链接的管理方便一点：

<!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">
<head runat="server">
    <title>Untitled Page</title>
<script language="javascript" type="text/javascript">
// <!CDATA[
var jsvar1="222"
function redir(href)
{
    document.getElementById("Hidden1").value=(href+jsvar1);
    document.getElementById("Button1").click();
}

// ]]>
</script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <a href="http://www.bla.com/test.aspx?var1=" onclick="redir(this.href); return false;">Mark</a>
    </div>
    <asp:Button style="display:none" ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
    <input id="Hidden1" type="hidden" runat="server" />
    </form>
</body>
</html>

protected void Button1_Click(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(Page, this.GetType(), "key", "window.location='"+this.Hidden1.Value+"'", true);
}
