<asp:button runat="server" ID="btn" text="Button" OnClick="aa_Click" />
CODE:
public void page_load(Object obj,EventArgs e)
{
btn.Attributes.Add("onclick","state=true;");
StringBuilder sb=new StringBuilder();
sb.Append("if (!state) return;");
sb.Append("var button=document.getElementById('btn');");
sb.Append("button.value='Please Wait...';");
sb.Append("document.body.style.cursor='wait';");
sb.Append("button.disabled=true;");
string strScript="<script>";
strScript=strScript +"var state=false;";
//将函数绑定到页面的onbeforeunload事件:
strScript=strScript +"window.attachEvent('onbeforeunload',function(){" +sb.ToString()+ "});";
strScript=strScript +"</"+"script>";
Page.RegisterStartupScript("onbeforeunload",strScript);
}
protected void aa_Click(object sender, EventArgs e)
{
//模拟长时间的按钮处理
System.Threading.Thread.Sleep(2000);
Response.Write("<script>alert('bbbbbb!!');" + "</" + "script>");
}
//======================================
或者
直接设置button的onclientclick属性：
<asp:Button ID="btnSave" runat="server" CssClass="btn1" Text="保 存" OnClick="btnSave_Click" OnClientClick="if(confirm('确定保存吗?')){this.value='数据提交中……';this.disabled=true;}else {return false ;}" UseSubmitBehavior="False" />
虽然没有加层显示的感官效果好，但是也能凑合着用了
//＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
或者
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (this.Request.HttpMethod == "post")
{
if (Submit1.IsRefresh()) {
Label1.Text = "请不要直接刷新页面,且不要重复提交";
}
}
}
}
