    <script type="text/javascript">
        var pageDefault = {
            btn1: document.getElementById('Button1'),
            btn2: document.getElementById('Button2'),
            csslink: document.getElementById('csslink'),
            init: function() {
                this.btn1.onclick = function() {
                    pageDefault.csslink.href = "Handler.ashx?id=1";
                }
                this.btn2.onclick = function() {
                    pageDefault.csslink.href = "Handler.ashx?id=2";
                }
            }
        }
        pageDefault.init();
    </script>
</body>
</html>

这是 ashx ProcessRequest

    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/plain";
        var id = context.Request.QueryString["id"];

        if (id == "1")
        {

            context.Response.Write(@"
body
{
  background: Blue;
}  

");
        }
        else if (id == "2")
        {
            context.Response.Write(@"
body
{
  background: Red;
}  

");
        }
        else
        {

        }
    }

尝试使用：

body
{
    /* Red */
    background-color: #ff0000;
}

body
{
    /* Blue */
    background-color: #0c00ff;
}
