有没有简单的能实时刷新的？
ajax不太懂啊。没学过。
百度了另一种是多少秒自动刷新的。可是那样的话就达不到实时刷新了。
public partial class exp2_Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Application["chat"] != null)
Label1.Text = (string)Application["chat"];
}
protected void Button1_Click(object sender, EventArgs e)
{
if (TextBox1.Text != "")
{
Application.Lock();
Application["chat"] = TextBox1.Text + "说:" + TextBox2.Text + "</br>" + Application["chat"];
Application.UnLock();
Label1.Text = (string)Application["chat"];
}
else
Response.Write("<script>alert('必须输入姓名')</script>");
}
}
