Confirm browser back button else stay on page
提问by Stephen Way
In javascript or jquery I need to add an alert when the user clicks on the browser back button that has an ok/cancel button model, but instead of "Ok" it should say Leave and instead of Cancel it should say Stay. Thanks
在 javascript 或 jquery 中，当用户单击具有确定/取消按钮模型的浏览器后退按钮时，我需要添加一个警报，但不是“确定”，而是“离开”，而不是“取消”，而是“保持”。谢谢

You can't control the confirmation dialog button text, it's a hard coded feature of confirm()and is whatever the browser has...not much you can do about it.
您无法控制确认对话框按钮文本，它是一个硬编码功能，confirm()并且是浏览器所具有的任何功能……您对此无能为力。
For the actual display you can use window.onbeforeunload, but it won't be specific to the back button, any action leaving the page will trigger this, for example:
对于实际显示，您可以使用window.onbeforeunload，但它不会特定于后退按钮，离开页面的任何操作都会触发此操作，例如：
window.onbeforeunload = function() {
return "Are you sure you wish to leave this delightful page?";
}
