在ASP.NET中防止頁(yè)面多次提交的代碼實(shí)現(xiàn)
作者:佚名
本文介紹在ASP.NET中防止頁(yè)面多次提交的代碼實(shí)現(xiàn)。
此處提供的代碼用來(lái)實(shí)現(xiàn)當(dāng)asp.net頁(yè)面中的某個(gè)Button被點(diǎn)擊后disable掉該頁(yè)面中所有的Button,從而防止提交延時(shí)導(dǎo)致的多次提交?;谥暗膐nceclickbutton腳本.
- //ASP.NET中防止頁(yè)面多次提交的代碼: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中防止頁(yè)面多次提交的代碼: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); //保證 __doPostBack(eventTarget, eventArgument) 正確注冊(cè)
- if(!IsPostBack)
- {
- System.Text.StringBuilder sb = new System.Text.StringBuilder();
- sb.Append("if (typeof(Page_ClientValidate) == 'function') { if (Page_ClientValidate() == false) { return false; }}"); //保證驗(yàn)證函數(shù)的執(zhí)行
- sb.Append("if(window.confirm('are you sure?')==false) return false;"); //自定義客戶端腳本
- sb.Append("disableOtherSubmit();"); // disable所有submit按鈕
- sb.Append(this.GetPostBackEventReference(this.Button3)); //用__doPostBack來(lái)提交,保證按鈕的服務(wù)器端click事件執(zhí)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!");
- }
- }
此處只是disable掉所有的submit button, 我覺(jué)得其它的可提交控件也是可以通過(guò)類似的方法來(lái)disable的.
以上就是ASP.NET中防止頁(yè)面多次提交的代碼實(shí)現(xiàn)。
