web动态添加控件

JS：

function CreateNode() {
    var div = document.getElementById('divMess');
    var Node = document.createElement("div"); //创建标签
    Node.innerHTML = "你好 ";
    Node.setAttribute("style", " 100%; float: left; height: 20px; line-height: 20px; text-align: center;");
    var text = document.createElement("input");
    text.setAttribute("type", "text");
    text.setAttribute("value", "");
    text.setAttribute("id", "txtMess");
    text.setAttribute("name", "mess");
    Node.appendChild(text);
    div.appendChild(Node);
    text.focus();
}

CS：

Label lblshow;
private void CreateNewContorl(string mess)
{
    lblshow = new Label();
    lblshow.Text = "<br />" + mess;
    lblshow.Width = 150;
    lblshow.Height = 100;
    lblshow.CssClass = "Label";
    this.PanShowGJ.Controls.Add(lblshow);
}
