• Is there a better acts_as_commentable for Rails?

  - by levi rosol

  Here's what I'm looking to do. I have a site where I want the user to be able to leave comments on various Models. acts_as_commentable is the obvious starting point for this, but I'm curious if there is a gem / plug-in with a more robust feature-set. For example: Pre-built partial(s) (w/ or w/o Twitter / FB buttons) Partial(s) that utilize jQuery Twitter and / or FB tunnels (push to the users twitter / FB when they comment) Pre-built mechanism for pushing other users comments to users viewing that Model I can see how some of this functionality could be app specific, however, a generic implementation seems like it would be useful. I'm curious if something like this exists or not.

• Using the system localizations on iPhone

  - by nevan

  I want to make a back button for a navigation controller with the title "Back" instead of the title of the previous controller. I'm using this code: UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", @"Back") style:UIBarButtonItemStyleBordered target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; I'd like to be able to skip localizing the "Back" string in my app (since I can only localize it in a limited number of languages). If I give my navigation controller no title, the back button will be automatically localized into whatever the language the user has chosen, so the system has translations of "Back" in many languages. Is there a way to access the localizations that are already present in the system and use them myself? These are things like "Back", "Cancel", "Done" and so on, which show up when creating one of the standard system buttons.

• How to run SpecFlow tests in Visual Studio 2010?

  - by testerboy

  Trying to get SpecFlow running with a fresh VS2010 Professional install. Created a new console application and added references to NUnit and SpecFlow. Created a SpecFlow feature. The .feature with the default template code is created. Now I try to run this test, but I don't understand how. When I right-click the project (at the top-level), there is no "Run test(s)" option in the mouse drop down menu. Didn't the SpecFlow install correctly, am I missing some references or some other tool I need to install?

• How can I run a function anytime anything is animated with jQuery?

  - by WillyCornbread

  Hi - I have some jQuery animations in my code to slide divs up and down in response to some mouse clicks and other logic. This is all working just peachy, however in IE 6 some of the smaller icon images on the page don't slide along with the rest of the div for some strange reason. They kind of stay put then flicker into the new position and I've chalked this up to an IE6 'feature'. Considering that I have to support IE6, I wanted to just hide the icons anytime an animation started, and show them again when the queue was empty. I couldn't find a reference to any kind of events or hooks into the queue itself and I'd rather not add the hide code, then the show code to every animation as a callback. Thanks if you can help- b

• Some input regarding Dojo (smooth css change on mouseover)

  - by Andy Walpole

  I've been playing around with Dojo over the last couple of days. The script below changes the background position of the list item when the mouse is over the link. dojo.query('a[class=main-menu-link]').forEach(function(linkTwo) { dojo.connect(linkTwo, "onmouseover", function(evt) { dojo.query('#main-menu ul li').forEach(function(linkThree) { dojo.style(linkThree, { "backgroundPosition": "right center", }); }); You can see it in action in the right hand side menu: http://www.mechanic-one.suburban-glory.com/ I'm trying to work out the best of way of giving it a smooth transition between the two states... I've been looking on the Dojo documentation page but I'm not sure what is the best way of approaching it.

• CSS image for submit button - clicking image must submit form

  - by Tom

  Please help, I have a form on wordpress. I want the user to be able to click an image instead of the standard submit button. I have the image appear and the submit button disappear - but nothing happens when I click on the image.

How to change input button image using CSS? Thanks for your help.

• Android: setting up a google map class. bit of advice required.

  - by Capsud

  Hey there, Ok so this is what i've got. Button anandabutton = (Button) findViewById(R.id.anandaAddressButton); anandabutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); startActivityForResult(myIntent,0); } }); This method opens up my MapClass class which at the moment I just have set to show the location of one place. But I have a load of buttons and rather than making a lot of different mapClass classes for each button, I am wondering can I just use the one class and depending on what button 'id' is pressed, it will check an 'if statement' and then put in the correct coordinates into the method to display the map. It would be a lot neater than coding up like 20-30 classes. I'm not sure if i've explained that right so if not let me know. Thanks for any help.

• Asp.net control inside of fancybox modal is not "working"

  - by studiothat

  Your typical "It doesn't work" freak out going on over here. Any direction would help. I have a login control on my master page and I'm trying to only display it using jquery fancybox and then redirect the user once they are logged in. But any buttons or controls that should do "something" when pressed when I put inside the fancy box are not responding. If I keep the div visible and then use the control not using fancybox I get the expected result. What are my options?

• Is there any "modern" text editor with command-line?

  - by Pedro Morte Rolo

  A command line in a text editor is a wonderful feature. It allows the user to explore the editor's functionality and learn it's shortcuts in a textual way. It's much faster than using the mouse, and it is much easier to memorise "shortcuts" this way. Emacs and VI provide this, though, emacs and vi are not "modern". By "modern", I mean one that is original built to cope with the modern de-facto standards of selecting, copying, pasting, cutting, undoing, redoing and auto-completing. Cream/vi or EmacsCUE are not valid options, since there are loads of things built over them that conflict with the mentioned stuff. Is there any alternative? (I do not intend to use the "modern" term as derrogatory. I love both Emacs and VI, but I hate their keyboard shortcut baggage.) (please do not advertise Vim and Emacs, that's not answering the question. I am asking for alternatives)

• jQuery image fade not working for unknown reason...?

  - by Henrik Petterson

  Just when I thought I was done for the night, another issue is keeping me awake. It appears that somehow I have broken the fade I was using on my thumbnails. If you go here: http://ftframes.com/milad2/ When you hover your mouse of the thumbnails, it should fade up. To give you an idea, this is a working version of the script: http://nothingcantouchme.com/stackoverflow.php#download_page As you can see, the hover works fine with the fade. And please mind the mess on this one, I just added it to demonstrate. Is there anyone that can kindly assist me in solving this issue? I would lie if I told you that I wasn't completely lost.

• jQuery switchClass

  - by Eric

  Is it possible to undo a switchClass transaition? I'd like an element to slowly obtain class A as you hover over it, and slowly lose it again once the mouse has moved away. However, the function appears to be glitchy, and calling .stop(0,1) doesn't seem to help. In fact, it seems to break it. I have a live example here. Yes, it's a 404 page, but that's not important. The navigation should be slowly gaining or losing a class, but it just jumps. The script can be found here. Is such a transition possible?

• ASP.Net - Gridview row selection and effects

  - by Clint

  I'm using the following code in attempt to allow the user to select a gridview row by clicking anywhere on the row (plus mouse over and out) effects. The code doesn't seem to be applied on rowdatabound and I can't break into the event. (It is wired). The control is in a usercontrol, that lives in a content page, which has a masterpage. protected void gvOrderTypes_RowDataBound(object sender, GridViewRowEventArgs e) { GridView gvOrdTypes = (GridView)sender; //check the item being bound is actually a DataRow, if it is, //wire up the required html events and attach the relevant JavaScripts if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes["onmouseover"] = "javascript:setMouseOverColor(this);"; e.Row.Attributes["onmouseout"] = "javascript:setMouseOutColor(this);"; e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(gvOrdTypes, "Select$" + e.Row.RowIndex); } }

• Why is my form triggering the wrong controller action?

  - by COCoach

  This form has multiple submit buttons, when clicked, it calls a simple JavaScript function to change the value of a hidden input (function is called "setHidden". This worked before, after some other not relevant code, it has ceased working. Essentially, the action it is supposed to call is never called, instead it seems to default back to a previous URL. The Form: <form action="/League/RemoveOwner" method="post"> <input type="hidden" value="1007" name="lid"/> <input type="hidden" value="0" id="index" name="index"/> <input type="image" src="../../Resources/Images/Delete.png" height="12" alt="Remove Owner" title="Remove Owner" onclick="setHidden('index', '1031')"/></a> coach<br /> </form> The Controller: [HttpPost] public ActionResult RemoveOwner(int id, string index) { //yada return PartialView(); } When clicking the image, it should call the remove owner controller, instead it calls the "View" controller: public ActionResult View(int id) { //yada return View(); }

• How do I trigger a single event defined for a class of objects

  - by mrbinky3000

  I have a question. I have 8 buttons that have unique incrementing id's and a shared class. <button class="btnChapter" id="btnChapter_1" value="1">1</button> <button class="btnChapter" id="btnChapter_2" value="2">2</button> <button class="btnChapter" id="btnChapter_3" value="3">3</button> ... In order to prevent me from duplicating code, I bound a click event to the btnChapter class instead of binding an event individually to each button's ID. $('.btnChapter').click(function(){ .. do stuff .. }); How do I trigger() the click() event only for #btnChapter_2? The following doesn't seem to work. $('#btnChapter_2').click()

• UITableView performance degrading after adding subviews on cell iphone sdk

  - by neha

  Hi all, In my application, I'm adding a label and two buttons on cell of UItableView [I have not created a separate cell class]. I'm adding these to cell and not cell.contentview. After I run my application on IPhone, the tableview cell rendering after I move the cells up-down, is very jerky. Is it because I'm not adding the views on cell.contentView or because I've not created a custom class for cell? Can anybody please help? Thanks in advance.

• How to detect tap on uiview with lots of controls?

  - by kodcu

  My problem is about tap detection. I have a uiviewcontroller and there are some controls on uiview (labels, buttons, tableview, imageview, etc..) When I tap the uibutton I display a small uiview (200x150), if the user taps the uibuttons in smallview I hide the smallview. But I can't hide the uiview if the user taps the background. I tried this code.. -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ //NSLog(@"Touches began."); [self hideShareView]; } It doesn't work if I tap the another button in the uiviewcontrols view. I just want my uiviewcontrol's uiview to react first. I think its about firstResponder but I dont know how to set it first. edit: i want it to work like a uiPopover in ipad.

• JQuery Accordion - bottom-up in stead of top-down

  - by Tim Geerts

  Hi there, I have a question about the accordion plugin for jQuery. Basically, I've got it to work on my site nicely, there's just one thing that I'd have liked it to do and that is bottom-up opening in stead of top-down. What I mean by that is that my 3 buttons just stand in the vertical menu (div) in the bottom. And when you click it, they'll slide open but upwards, not downwards. Is there a way to achieve this easily? I've gone through the documentation, but can't find any native support for it, so I was wondering if it was possible to do it in the javascript of the plugin itself. Thanks in advance.

• Text Link is Hiding my Image Link

  - by icu222much

  I have a image where text/link is overlayed on top. My problem is that sometimes the text in the foreground will hide the link in the image in the background. I assume this is because the text box forms an invisible rectangle around the text, thus creating a region that appears it should belong to the image but is actually being covered by the text. I am wondering if it is possible that when I mouse over this region, I will be linking to my image link as oppose to my text link (see illustration). http://jsfiddle.net/WHpMr/

• Code Interaction with Quartz Composition

  - by Alberto MQO

  Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!
