back-button

问题 I'm trying to implement back button on this full ajax website.. I tried jquery history plugin but I'm sure I messed something, as the hash appears OK but the back button won't load the original content back..

问题 I know this borders on the taboo here, and please don't reply with "you should never do this", etc. I have a very long form in a wizard, and some users are too used to using the browser's back and forward buttons that they use those instead of the "Back" and "Next" buttons on the form wizard. If they hit the browser's back button, they will lose all of their form data (which is a pain in the ass, since the form is so long). Is it possible to display an alert that when will have a "take me out

问题 Currently I have one activity, and fragments are being added to it (search, song details, settings, etc). I implemented side based menu navigation, so now, as a side effect, tehre's no limit to how many Fragments get added to the Backstack. Is there any way I can limit the number of fragments, or remove older entries? Each song details fragment for instance, has a recommended song list, and through that you can go to another song details fragment. It's easily possible to have 30 fragments in

问题 I have a little Ionic 4 App with 2 Tabs and 1 Detail Page. The Problem I'm facing here is that if I go from Tab2 into Detail Page and from there with ion-back-button back it always redirect me to Tab1 instead of Tab2 where I was before.

问题 How can I make my Android app react to the back-button? Is there something as high-level VCL's TApplicationEvents to handle it, or do I need to dive deep into low-level Android-specific stuff here? Right now, most of the demo applications have an on-screen back button to go back to a previous screen. Pressing the psysical button always seems to quit the app, and in some situations it results in an access violation. 回答1: In the form's OnKey... events, the Key parameter is vkHardwareBack on

问题 I have a form with an array of text fields. The user (through javascript) can add an arbitrary number of text fields to the form. After submitting the form and pressing the back button the form displays only with the fields that were on the original form when it was first rendered (any added text fields are lost).
