此处提供的代码用来实现当asp.net页面中的某个Button被点击后disable掉该页面中所有的Button，从而防止提交延时导致的多次提交。基于之前的onceclickbutton脚本.
//ASP.NET中防止页面多次提交的代码:javascript< script language="javascript"> < !-- function disableOtherSubmit() {
var obj = event.srcElement;
var objs = document.getElementsByTagName('INPUT');
for(var i=0; i< objs.length; i++)
{
if(objs[i].type.toLowerCase() == 'submit')
{
objs[i].disabled = true;
}
}
} //--> < /script>//ASP.NET中防止页面多次提交的代码:asp.netpublic class PreventMultiClick : System.Web.UI.Page {
protected System.Web.UI.WebControls.Button Button1; protected System.Web.UI.WebControls.Button Button2;
protected System.Web.UI.WebControls.LinkButton LinkButton1; protected System.Web.UI.WebControls.Button Button3; private void Page_Load(object sender, System.EventArgs e)
{
this.GetPostBackEventReference(this.Button3);
//保证 __doPostBack(eventTarget, eventArgument) 正确注册 if(!IsPostBack)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("if (typeof(Page_ClientValidate) == 'function')
{
if (Page_ClientValidate() == false)
{
return false;
}
}"); //保证验证函数的执行 sb.Append("if(window.confirm('are you sure?')==false) return false; ");
//自定义客户端脚本 sb.Append("disableOtherSubmit(); ");
// disable所有submit按钮 sb.Append(this.GetPostBackEventReference(this.Button3));
//用__doPostBack来提交，保证按钮的服务器端click事件执行 sb.Append("; ");
Button3.Attributes.Add("onclick",sb.ToString());
}

文件上传界面既可以用Html的input file控件，又可以用FileUpload控件，只要将Html的input file控件加上runat="server"，就会发现两者的功能完全是一模一样，上传的代码是共用的，不需要做任何改变。我想微软在将Html控件将成标准控件时应该只是多加了runat="server"吧。放入上述两者的任一控件后，添加一个标准的Button按钮 ......
在web config中 作如下配置：
<connectionStrings>
<add name="ydycon" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=|DataDirectory|ydy.mdb" providerName="System.Data.OleDb"/>
</connectionStrings>
在.net文件中应用链接 ......
