Close the current page: <a href= "Javascript:window.opener=null;window.close ();" > Close </a>, if the button is:
Response.Write ("<script language=/" javascript/">window.opener=null;window.close ();</script>");
This will not pop up as the current window is trying to close the dialog box.
So how about when the user-point browser maximizes the Close button in the Close button, it also pops up the closed confirmation dialog box? This way:
<body onbeforeunload= "Return" really want to close this window? ' " > In this case, the onbeforeunload function will be executed when the point is closed, pop the dialog box that really wants to close this window, click Cancel return false, do not close, point OK return true close window
So how can you click a button when the pop-up OK Cancel dialog box?? If you do not execute the following code if you click Cancel, click OK to continue with the following code?
Write in the click of the button:
Response.Write ("<script language=/javascript/" > "+" if (Confirm (/"OK?/")) "+" {window.location.href= ' Default.aspx ';} ' + "Else{history.back ();}" + "</script>");
This means: first with the Confirm function pop-up with a certain cancellation dialog box, if you click OK to return to true, the implementation of the window.location.href= ' default.aspx ' code, if the point of cancellation on the return of false, on the implementation of History.back () ; Go back to the original page
Of course, we can also write this:
private void Btnchong_click (object sender, System.Web.UI.ImageClickEventArgs e)
{
Response.Write ("<script language=/" javascript/">" + "if (!confirm) (Are you sure you want to recharge it?/") "+" {history.back ();} "+" </ Script> ");
First pops up a dialog box with a OK Cancel button, and if the point is canceled, return to the original page and the following code will not be executed
String connstring = configurationsettings.appsettings["ConnStr"]. ToString () + Server.MapPath (Request.applicationpath) + "Hualong.mdb ";
