由 喜你入骨 提交于 2019-12-24 07:26:22
问题 I have come across some strange behaviour, and I'm assuming a bug in firefox, when removing a input submit element from the DOM from within the click event. The following code reproduces the issue: <form name="test_form"> <input type="submit" value="remove me" onclick="this.parentNode.removeChild(this);" /> <input type="submit" value="submit normally" /> <input type="button" value="submit via js" onclick="document.test_form.submit();" /> </form> To reproduce: Click "remove me" Click "submit

How to show a modal dialog before beforeunload shows its own?

由 拜拜、爱过 提交于 2019-12-24 04:43:06
问题 I do understand that it's not possible to replace the beforeunload dialog with a custom one, and that if we need to set a custom message to the user, we'll have to return a string in our beforeunload handler: {Custom message here set by returning a string in our beforeunload handler} Are you sure you want to leave this page?
