前台代码:

 <asp:button id="button1" runat="server" text="打印"  onclick="button1_click" onclientclick="this.value='数据提交中……';this.disabled=true;" usesubmitbehavior="false" />

后台代码:

            var temp = times%5;

    public void submitload(button btn)
    {
      btn.attributes.add("onclick", "javascript:document.getelementbyid('pagebase_runing').style.visibility='visible';window.setinterval('pagebase_tick()',500);");

      lbtn.attributes.add("onclick",
                 "javascript:document.getelementbyid('pagebase_runing').style.visibility='visible';window.setinterval('pagebase_tick()',1000);");
    }
    protected void page_load(object sender, eventargs e)
    {
      submitload(button1);
    }
    protected void button1_click(object sender, eventargs e)
    {
      button1.enabled=false;
      //string ip = printinglabel.searchprinterip(textbox1.text, textbox2.text, textbox3.text);
      //response.write(ip);
      int ifs=0;
      for (int i = 0; i < 1000000000; i++)
      {
        ifs++;
      }
    }
  }
}

以上所述是小编给大家介绍的asp.net中避免重复提交和弹出提示框的实例代码,希望对大家有所帮助
