使用javascript / jquery在c#中关闭浏览器之前的警告 [英] warning before browser close in c# using javascript/jquery
问题描述
我只能在我的page.aspx.cs写一个脚本。
我是包括我的代码中的以下行
$(window).on(' unload',function(){
alert(' 再见!' );
});
关闭浏览器后发出警报。所以,我正在使用
$(window).on(' beforeunload',function(){
return ' 你确定!';
});
不工作
可以帮助我任何人,我想要在关闭浏览器之前发出警告,只有当按下右上方的红色十字按钮时才显示页面刷新或重定向到另一页。
请帮助我。
(窗口).on(' unload',function(){

试试这个javascript函数: -
< script type = text / javascript >
var close = true;
window.onbeforeunload = function(){
if(close){
return希望你喜欢它。
}
}
函数unhook(){
close = false;
}
< / script > 跨度>
