  • button onclick not working

    - by nsw1475
    I have a javascript where I need to hide (and eventually show) some text by clicking a button. However, when I click the button, it does not call the function specified in the onclick parameter, and so nothing happens. Here is my source code: <script type="text/javascript"> $(document).ready(function(){ var tip = 1; $(".tip1").hide(); $(".tip2").hide(); switch (tip) { case 1: $(".tip1").show(); break; case 2: $(".tip2").show(); break; } function nextTip() { $(".tip1").hide(); return; } }); </script> <br/> <div id='bg_container' style='background-image: url("<?=$PICS?>trackingpage_middle.jpg")' > <img style='z-index:-1;' width='737px' src='<?=$PICS?>trackingpage_top.jpg'> <div id='main_container' > <form> <input type="button" onClick="nextTip()" value = "Next Tip" /> </form> <div class="tip1"> ... and so on.

  • In SVG is there a way to grab a shape anywhere when it has fill = "none"

    - by Shaunwithanau
    I have a series of shapes that I want the user to be able click anywhere on the shape to pick up as part of a drag and drop feature. All of these shapes are bounded by a rectangle. For example: <g id="shape1" fill="none" stroke="black"> <rect x="0" y="0" width="100" height="100"/> <circle cx="50" cy="50" r="50"/> </g> <g id="shape2" fill="none" stroke="black"> <rect x="0" y="0" width="100" height="100"/> <line x1="0" y1="0" x2="50" y2="100"/> <line x1="100" y1="0" x2="50" y2="100"/> </g> I already have all of the drag and drop parts working, the problem is all of these shapes have to have fill="none" so you can see anything that may be underneath of them. This means that even though they are bounded by the rectangle, at the moment users have to physically click on one of the lines in order to pick it up instead of being able to click anywhere on the shape like I want. My original idea was to use fill="white" and then set opacity="0" or some really low value but this applies to the stroke as well so this didn't work out. Any ideas on how I can get this working?

  • View isn't scrolling back down after I dismiss the keyboard

    - by fmi
    I have a Tab Bar app. One of the views has a UITextView that is hidden by the keyboard when touched. I've set the view to scroll to account for the keyboard but it the view doesn't always return to it's original position after I dismiss the keyboard. Here is my code: //Scroll the view for keyboard - (void)viewWillAppear:(BOOL)animated { void (^keyBoardWillShow) (NSNotification *)= ^(NSNotification * notif) { NSDictionary* info = [notif userInfo]; NSValue* aValue = [info objectForKey:UIKeyboardFrameEndUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; float bottomPoint = (additionalView.frame.origin.y + additionalView.frame.size.height + 10); scrollAmount = keyboardSize.height - (self.view.frame.size.height - bottomPoint); if (scrollAmount > 0) { moveViewUp =YES; [self scrollTheView:YES]; } else moveViewUp = NO; }; [[NSNotificationCenter defaultCenter] addObserverForName:UIKeyboardWillShowNotification object:self.view.window queue:nil usingBlock:keyBoardWillShow]; void (^keyBoardWillHide) (NSNotification *)= ^(NSNotification * notif) { if (moveViewUp) [self scrollTheView:NO]; }; [[NSNotificationCenter defaultCenter] addObserverForName:UIKeyboardWillHideNotification object:self.view.window queue:nil usingBlock:keyBoardWillHide]; [super viewWillAppear:animated]; } - (void)viewWillDisappear:(BOOL)animated { [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil]; [super viewWillDisappear:animated]; } (void)scrollTheView:(BOOL)movedUp { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.3]; CGRect rect = self.view.frame; if (movedUp){ rect.origin.y -= scrollAmount; } else { rect.origin.y += scrollAmount; } self.view.frame = rect; [UIView commitAnimations]; }

  • Which is the event listener after doSave() in Symfony?

    - by fesja
    Hi, I've been looking at this event-listeners page http://www.doctrine-project.org/documentation/manual/1_1/pl/event-listeners and I'm not sure which is the listener I have to use to make a change after the doSave() method in the BaseModelForm.class.php. // PlaceForm.class.php protected function doSave ( $con = null ) { ... parent::doSave($con); .... // Only for new forms, insert place into the tree if($this->object->level == null){ $parent = Place::getPlace($this->getValue('parent'), Language::getLang()); ... $node = $this->object->getNode(); $method = ($node->isValidNode() ? 'move' : 'insert') . 'AsFirstChildOf'; $node->$method($parent); //calls $this->object->save internally } return; } What I want to do is to make a custom slug with the ancestors' name of that new place. So if I inserting "San Francisco", the slug would be "usa-california-san-francisco" public function postXXXXXX($event) { ... $event->getInvoker()->slug = $slug; } The problem is that I'm inserting a new object with no reference to its parent. After it's saved, I insert it to the tree. So I can't change the slug until then. I think a Transaction listener could work, but I'm use there is a better way I'm not seeing right now. thanks!

  • Handling download abort in PHP

    - by Aron Rotteveel
    Is it somehow possible to handle a download abort in PHP? In this specific case I am not speaking of a connection abort, but handling the event that triggers when the 'cancel' button in the browser download dialog button is clicked. Since this dialog already interprets the headers of the file that is to be download but does not actually start the download, it only seems logical there should be some way to catch this. Small (pseudo) code example to clear things up: // set some headers header('...'); // Question: what happens between the part where the headers are sent // and the actual data is being outputted to the client? IE: this is the part // where the download dialog should show up // Logical question that follows is: is there a way to detect a 'cancel'? $filename = '/some/file.txt'; $handle = fopen($filename, 'rb'); // output data to client while (!feof($handle)) { echo fread($handle, 8096); } fclose($handle);

Would the .click() event be triggered in this case as well?

  • Progressive enhancement of anchor tags to avoid onclick="return false;"

    - by Chris Beck
    Unobtrusive JS suggests that we don't have any onclick attributes in our HTML templates. <a href="/controller/foo/1">View Foo 1</a> A most basic progressive enhancement is to convert an that anchor tag to use XHR to retrieve a DOM fragment. So, I write JS to add an event listener for a."click" then make an XHR to a.href. Alas, the browser still wants to navigate to "/controller/foo". So, I write JS to dynamically inject a.onclick = "return false;". Still unobtrusive (I guess), but now I'm paying the the cost of an extra event handler. To avoid the cost of 2 event listeners, I could shove my function call into the onclick attribute <a href="/controller/foo/1" onclick="myXHRFcn(); return false;"> But that's grodo for all sorts of reasons. To make it more interesting, I might have 100 anchor tags that I want to enhance. A better pattern is a single listener on a parent node that relies on event bubbling. That's cool, but how do I short circuit the browser from navigating to the URL without this on every anchor node? onclick="return false;" Manipulating the href is not an option. It must stay intact so the context menu options to copy or open in new page work as expected.

  • Restricting numeric input javascript problem

    - by neitony
    I'm trying to figure out why my javascript code is not restricting numeric input. Here's the code below: (function(){ if(window.addEventListener) window.addEventListener("load",init,false); else if(window.attachEvent) window.attachEvent("onload",init); function init() { var keytest = document.getElementById("keytest"); function numericinput(event) { var e = event || window.event; var key = e.charcode || e.keyCode; var regex =/^\d+\.?\d{4}$/; key = String.fromCharCode(key); if (!regex.test(key)) { alert("something"); //if(e.preventDefault) e.preventDefault(); //if(e.returnValue) e.returnValue = false; //return false; } else { //return true; alert("something else"); } } if(keytest.addEventListener) keytest.addEventListener("keypress",numericinput,false); else { keytest.onkeypress = numericinput(); } } })();

  • Detecting support for a given JavaScript event?

    - by Will
    I'm interested in using the JavaScript hashchange event to monitor changes in the URL's fragment identifier. I'm aware of Really Simple History and the jQuery plugins for this. However, I've reached the conclusion that in my particular project it's not really worth the added overhead of another JS file. What I would like to do instead is take the "progressive enhancement" route. That is, I want to test whether the hashchange event is supported by the visitor's browser, and write my code to use it if it's available, as an enhancement rather than a core feature. IE 8, Firefox 3.6, and Chrome 4.1.249 support it, and that accounts for about 20% of my site's traffic. So, uh ... is there some way to test whether a browser supports a particular event? Thanks.

  • Trying to perform a series of actions on page unload, but the pages unloads too fast to finish them.

    - by user138821
    I have a series of actions I want to perform on page unload. Namely if a user is editing an input field, and they refresh or close browser or leave page, I want to save the contents of the field. The actions don't include an AJAX call, so I can't just make it synchronous. It's actually saving to local storage, but the page unloads before the storage can take place. The code is correct, if I add an alert to the actions, the delay allows the rest of the code to finish before it even displays. Any ideas? Thanks!

  • Loading HTML5 video on iPad via onclick event tied to a div

    - by joncys
    I'm developing an HTML5 application (a game), that automatically preloads 5 video files. I'm able to do so correctly on Safari for PC, so there are no overlooked problems with file formats, codecs or such. The load fails on an iPad. As an official guide for video on iOS puts it: This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not. Does this mean, that I have no means to initiate the loading of video after a user initiated action, if that action hasn't been tied to a video element (user clicked on a regular div — I request loading and displaying of a video, compared to the user actually clicking on a video element to load and play that particular element)? Thanks for your help!

  • Javascript: How to detect if a word is highlighted

    - by fterh
    I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.

  • Event in Global.asax file that fires only for once

    - by fiberOptics
    In MVC Global.asax file, we can see the Application_Start where this event fires only for once. But the session is not yet active/available here. So my question is, is there any event in Global.asax file that fired only for once and session is available also? The reason I ask this is because, I use ExpandoObject e.g.: public static dynamic Data { get { #region FAILSAFE if (HttpContext.Current.Session[datakey] == null) { HttpContext.Current.Session[datakey] = new ExpandoObject(); } #endregion return (ExpandoObject)HttpContext.Current.Session[datakey]; } } I want to initialize all of my ExpandoObject at once with the value of null: MyExpando.Data.UserInformation = null; MyExpando.Data.FolderInformation = null; That's why I'm looking for an event that only fired once.
