  • Alert user when they hit the browser back button - with good reson

    - by Dirty Bird Design
    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, some users are too used to using the browsers back and forward buttons that they use those instead of the "Back" and "Next" buttons on the form wizard. If they hit the browsers back button they lose all of their form data which is a pain in the ass, since form is so long. Is it possible to display an alert that when will have a "take me out of here" and a "cancel" button so if they hit cancel it will cancel the function of the back button? Thanks!

  • How to determine which enemy is hit and destroy it alone

    - by Jon Ferriter
    http://jsfiddle.net/5DB6K/ I have this game being made where you shoot enemies from the sides of the screen. I've got the bullets moving and being removed when they reach the end of the screen (if they didn't hit any enemy) and removing the enemy when they collide with it. //------------collision----------------// if(shot === true){ bulletY = $('.bullet').position().top + 2; bulletX = $('.bullet').position().left + 2; $('.enemy').each(function(){ if($('.enemy').hasClass('smallEnemy')){ enemyY = $(this).position().top + 7; enemyX = $(this).position().left + 7; if(Math.abs(bulletY - enemyY) <= 9 && Math.abs(bulletX - enemyX) <=9){ $(this).remove(); score = score + 40; bulletDestroy(); } } }); } However, the bullet destroys every enemy if the collision check is right which isn't what I want. I want to check if the enemy has the class of either smallEnemy, medEnemy, or lrgEnemy and then do the collision check which is what I thought I had but it doesn't seem to work. Also, the game starts to lag the more and more time goes on. Would anyone know the reason for that?

  • Is it possible to do an Ajax request for an ICS file?

    - by Kyle
    I am trying to do an Ajax request for an ICS file. Yeah, I know it sounds crazy, but I found the perfect library to parse the iCal data. Any ideas why the data comes up blank when I do this? $.ajax({ success:function(data){ alert(data); }, url:"http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=15714&cat=98&platform=osx&method=sa/Swiss32Holidays.ics" }); It makes the request fine, but the data still comes up blank.

  • 2 ajax forms on the same page posting same textbox

    - by rod
    Hi All, Is it possible to post, say like a value in a textbox, to 2 different ajax forms that are on the same page? It doesn't have to be at the same time? What I'm trying to do is this: I have a search page that searches for customers and displays them on a paged grid. Users can specify up to 5 parameters (5 textboxes) to narrow the search. On the same page I have an export option. Well since I want all the customers for the search and not just the paged data I need a way to post back to the server for this option passing the same parameters used in the grid. I'm using a ViewModel which would be nice if I can pass that back to the server rather than the individual search fields that are backed by the view model. Thanks, rodchar

    - by Mher
    lets say I have a html page. <html> <body> ... This is my HTML Page, full of html objects and mouse events on them ... <div id='blocker' style="height: 100%; position: absolute; width: 100%; top: 0px; left: 0px; right: 0px; bottom: 0px; z-index: 1001; background: none repeat scroll 0% 0% black; opacity: 0.5;"></div> <div id='window_to_my_html_page' style="display: block; left: 50px; top: 50px; width: 200px; height: 200px; z-index: 1002; position: absolute;"></div> </body> </html> In this example div which id is 'blocker' will block all mouse events from my page. All my HTML page elements behind of my second div(which id is 'window_to_my_html_page') must be active, all mouse events must work on them, this div must be like a window to my HTML page I want to make all elements from my HTML page active(to work as normal) inside this area (left: 50px; top: 50px; width: 200px; height: 200px).... and other content, outside of this area make inactive The question: how can I do it?

  • How to select every node that holds the same ID

    - by Asaf
    Hello, I have a Jstree that holds a lot of nodes, some of them have the same ID. I was wondering, how do I make it so that if someone selects one of the nodes, it would select every node with the same id. I tried working with the onselect: function (node) { but I'm not sure what exactly to do, plus I'm not sure how to manually select a node (because it's all done with the selected: attribute)
