I have requirements to code something that I need some help with. I am encountering the following issue: I need to display a window right before someone leaves the page they are on. Basically prompt them to save their changes or continue on to the next page. On the save I execute an AJAX request to Save and then they go on to the next page. Well I can do this easily using the regular javascript confirm object: <body onunload="var x=confirm("save changes");if(x) ajxcalltosave();">
However I need to do this using the prototype window. As I need to override the button choices to be "yes, save" or "no, don't". (which to my knowledge you cannot do with confirm) During the unload event-- When I instantiate a Dialog.confirm window via prototype's libraries the window shows up for a split second and the user gets redirected to the next page. I want to make the prototype window stay before moving on to the next page. That is the issue. I have used it before and can display the window and it behaves properly on every other event other than unload, and I don't understand why. I'm sure if I step through the code enough times I should hopefully find some clue as to its behavior. But haven't found any so far. I could open another window referring to a different page with the question and buttons, in which case the parent page would already move on and I'd have to pass all the information to execute the save as parameters to the request displayed in the new window. That would be kind of cloojy. If there is some way I could abort the unload or redirect back to the same page then show the Dialog.confirm window that would work but I would need to know where the user initially intended on leaving to so that I could redirect them there after the save. RECAP Option 1: Override confirm's button choices. CON: Not possible as per my knowledge Option 2: Make the prototype window not disappear before moving on to the next page. CON: I don't know how Option 3: Open another window CON: Not pretty, the parent page moves on before the save occurs, would not appease requirements Option 4: Abort the unload, stay on the same page CON: Need to know where the user meant to go so they could be redirected back there later Thank you for reading this. If you can provide some insight to my issue, I'd really appreciate it. (I really would like to be able to execute option 2.) :-) radha --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
