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.net
- 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());
- }
- }
- #region Web Form Designer generated code
- override protected void OnInit(EventArgs e)
- {
- //
- // CODEGEN: This call is required by the ASP.NET Web Form Designer.
- //
- InitializeComponent();
- base.OnInit(e);
- }
- /// < summary>
- /// Required method for Designer support - do not modify
- /// the contents of this method with the code editor.
- /// < /summary>
- private void InitializeComponent()
- {
- this.Button3.Click += new System.EventHandler(this.Button3_Click);
- this.Load += new System.EventHandler(this.Page_Load);
- }
- #endregion
- 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.
以上就是ASP.NET中防止页面多次提交的代码实现。
