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.
<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>
public 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());
}
}

private void Button3_Click(object sender, System.EventArgs e)
{
System.Threading.Thread.Sleep(3000);
Response.Write("Hello world!");
}
}
此处只是disable掉所有的submit button, 我觉得其它的可提交控件也是可以通过类似的方法来disable的.
