@jAndyが述べたように、ウィンドウが閉じられたことを検出するための適切なJavaScriptコードはありません。@Synoの提案から始めました。
私はそのような状況を通過しました、そしてあなたがこれらのステップに従えばあなたはそれを検出することができるでしょう。
Chrome 67以降とFirefox 61以降でテストしました。
var wrapper = function () { //ignore this
var closing_window = false;
$(window).on('focus', function () {
closing_window = false;
//if the user interacts with the window, then the window is not being
//closed
});
$(window).on('blur', function () {
closing_window = true;
if (!document.hidden) { //when the window is being minimized
closing_window = false;
}
$(window).on('resize', function (e) { //when the window is being maximized
closing_window = false;
});
$(window).off('resize'); //avoid multiple listening
});
$('html').on('mouseleave', function () {
closing_window = true;
//if the user is leaving html, we have more reasons to believe that he's
//leaving or thinking about closing the window
});
$('html').on('mouseenter', function () {
closing_window = false;
//if the user's mouse its on the page, it means you don't need to logout
//them, didn't it?
});
$(document).on('keydown', function (e) {
if (e.keyCode == 91 || e.keyCode == 18) {
closing_window = false; //shortcuts for ALT+TAB and Window key
}
if (e.keyCode == 116 || (e.ctrlKey && e.keyCode == 82)) {
closing_window = false; //shortcuts for F5 and CTRL+F5 and CTRL+R
}
});
// Prevent logout when clicking in a hiperlink
$(document).on("click", "a", function () {
closing_window = false;
});
// Prevent logout when clicking in a button (if these buttons rediret to some page)
$(document).on("click", "button", function () {
closing_window = false;
});
// Prevent logout when submiting
$(document).on("submit", "form", function () {
closing_window = false;
});
// Prevent logout when submiting
$(document).on("click", "input[type=submit]", function () {
closing_window = false;
});
var toDoWhenClosing = function() {
//write a code here likes a user logout, example:
//$.ajax({
// url: '/MyController/MyLogOutAction',
// async: false,
// data: {
// },
// error: function () {
// },
// success: function (data) {
// },
//});
};
window.onbeforeunload = function () {
