如何防止窗户。在ajax响应中使用javascript的onbeforeunload函数

2 个解决方案

#1

You can turn off the handler in the AJAX callback:

您可以在AJAX回调中关闭处理程序:

 if(data) {
    window.onbeforeunload = undefined;
    window.location.href=baseurl+'index.php/functionname/'+arg_id; 
    }

#2

You can use a Global variable as follows:

您可以使用以下全局变量:

var confirm = true;

In your ajax response set confirm to false as follows:

在您的ajax响应集中确认为false，如下所示:

$.ajax({
 type: "POST",
 url: baseurl+"index.php/sample/samplefunction",
 data: {"demo_detail":sse,'demo_detail':pro},
 success:function(data) {
  if(data) {
     confirm = false;
     window.location.href=baseurl+'index.php/functionname/'+arg_id; 
  }
 }
});

In your "comfirmExit()" function, heck if confirm is try, then only alert the waring to the user.

在“comfirmExit()”函数中，如果尝试确认，那么只向用户发出警告。

window.onbeforeunload = confirmExit;
function confirmExit()
{
   if(confirm)
     return "You have attempted to leave this page. Are you sure you want to exit this page?";
   else
     return;
}
