  • Migrating from jQuery to Prototype

    - by Craig Gardner
    I'm starting to write code using Prototype coming from a jQuery background. Is there any chart that shows the prototype equivalent method to use in place of specific jQuery methods? More specifically, I'm looking for a $('#my-id').prepend('some stuff') equivalent in prototype?

  • Remove tabstop from ButtonColumn inside DataGrid

    - by Faruz
    Is there any way to disable keyboard tabStop for a ButtonColumn inside a dataGrid? I want the buttons there to be only enabled through mouse-clicks, because sometimes the grid can be large and I want that pressing "tabs" will skip the grid and move to the other controls on the page.

  • CSS autohide scrollbar when not scrolling on Android webpage

    - by b0Gd4N
    Is there a way to make the scrollbar auto-hide when a user is not scrolling a webpage on an Android device, but make it visible when it is scrolling? Please note that Firefox browsers does have this behaviour enabled by default, it's just Chrome and stock(Samsung, HTC) browsers that don't. This is what I currently have: -webkit-box-flex: 1; width: 100%; overflow: auto; -webkit-overflow-scrolling: touch; And I can always see the scrollbar on the list (except in ffox)

  • Use javascript variables in Rails view helpers

    - by Horacio
    Using jqGrid I want to generate delete links for each row in the grid. The standard way to do this is to add the links in the gridComplete callback like shown below: gridComplete: function() { var ids = jQuery("#jobs_table").jqGrid('getDataIDs'); for(var i=0;i < ids.length;i++){ var cl = ids[i]; be = '<%= link_to(image_tag("delete.gif", :border=>0, :size=>"20x22", :alt => "delete"),· { :action => 'destroy', :id => 'cl', :method => :delete}, :class => 'ajax') -%>'; jQuery("#jobs_table").jqGrid('setRowData',ids[i],{workflow_state:be}); } }, Using getDataIDs I get a list of IDs that I can use to generate the delete links. The problem is that this is a javascript call that results in a javascript variable. The question is how can I use this variable "cl" inside rails link_to view helper?

  • How can I specify my own Rhino context in Java?

    - by Dan Howard
    I'm trying to ensure that my Rhino scripts (running under Java 6) are strict so that if a script developer misspells an expression I want an exception to be thrown. Currently what happens is the expression simply evaluates to "undefined". Now according to Mozilla org https://developer.mozilla.org/en/New_in_Rhino_1.6R6 there are features to enable strict checking in the context. I cannot find a working example of this. What I did so far was write a class to extend ContextFactory and then override the hasFeature method. public class ScriptContextFactory extends ContextFactory { protected boolean hasFeature(Context context, int featureIndex) { switch (featureIndex) { case Context.FEATURE_STRICT_EVAL: return true; case Context.FEATURE_STRICT_VARS: return true; } return super.hasFeature(context, featureIndex); } } Then in the Main I set mine to the default. ContextFactory.initGlobal(new ScriptContextFactory()); and I get an illegal state exception. :( Any ideas or samples on how this works? TIA

  • jQuery Address double load on init

    - by dazhall
    Hi All! I'm using jQuery Address to load in my content, but it's doing it twice on the init. I set it up so that if you go to the main category it loads the first image, but it's doing it twice and I'm not sure how to stop it. A fresh pair of eyes would be appreciated! $.address.init(function(event) { $('#carousel-clip a').address(); if(!event.pathNames[0]) { var url = $('#carousel-clip ul li:first a').attr('href').replace('#!/',''); $.address.path(url); } }).change(function(event) { if(event.pathNames[0]) { $.getJSON(location.pathname + 'image/' + event.pathNames[0] + '/', function(data, textStatus, XMLHttpRequest) { handler(data); }); } }); You can see it working here: http://bit.ly/cKftwA Thanks! Darren.

  • Simulating "focus" and "blur" in jQuery .live() method...

    - by Jonathan Sampson
    Update: As of jQuery 1.4, $.live() now supports focusin and focusout events. jQuery currently1 doesn't support "blur" or "focus" as arguments for the $.live() method. What type of work-around could I implement to achieve the following: $("textarea") .live("focus", function() { foo = "bar"; }) .live("blur", function() { foo = "fizz"; }); 1. 07/29/2009, version 1.3.2

  • Cast/initialize submodels of a Backbone Model

    - by nambrot
    I think I have a pretty simple problem that is just pretty difficult to word and therefore hard to find a solution for. Setup: PathCollection is a Backbone.Collection of Paths Path is a Backbone.Model which contains NodeCollection (which is a Backbone.Collection) and EdgeCollection (which is a Backbone.Collection). When I fetch PathCollection paths = new PathCollection() paths.fetch() obviously, Paths get instantiated. However, I'm missing the spot where I can allow a Path to instantiate its submodels from the attribute hashes. I can't really use parse, right? Basically im looking for the entry point for a model when its instantiated and set with attributes. I feel like there must be some convention for it.

  • Uncaught TypeError: Cannot read property 'length' of undefined

    - by AnApprentice
    I'm working to built a contact list that is grouped by the first letter of the contact's last name. After a succesfull ajax request, the contact is pushed to addContact: Ajax success: ko.utils.arrayForEach(dataJS.contactList, function(c) { contactsModel.addContact(c); }); contactsModel.addContact: //add a contact in the right spot under the right letter contactsModel.addContact = function(newContact) { //grab first character var firstLetter = (newContact.lname || "").charAt(0).toUpperCase(); //if it is a number use # if (!isNaN(firstLetter)) { firstLetter = "#"; } //do we already have entries for this letter if (!this.letterIndex[firstLetter]) { //new object to track this letter's contacts var letterContacts = { letter: firstLetter, contacts: ko.observableArray([]) }; this.letterIndex[firstLetter] = letterContacts; //easy access to it //put the numbers at the end if (firstLetter === "#") { this.contactsByLetter.push(letterContacts); } else { //add the letter in the right spot for (var i = 0, lettersLength = this.contactsByLetter().length; i < lettersLength; i++) { var letter = this.contactsByLetter()[i].letter; if (letter === "#" || firstLetter < letter) { break; } } this.contactsByLetter.splice(i, 0, letterContacts); } } var contacts = this.letterIndex[firstLetter].contacts; //now we have a letter to add our contact to, but need to add it in the right spot var newContactName = newContact.lname + " " + newContact.fname; for (var j = 0, contactsLength = contacts().length; j < contactsLength; j++) { var contactName = contacts()[j].lName + " " + contacts()[j].fName; if (newContactName < contactName) { break; } } //add the contact at the right index contacts.splice(j, 0, newContact); }.bind(contactsModel); The contacts json object from the server looks like this: { "total_pages": 10, "page": page, "contactList": [{ "photo": "http://homepage.mac.com/millhouse/Family%20Tree/images/PersonListIcon.png", "lname": "Bond", "id": 241, "fname": "James", "email": "[email protected]"}, While this works in jsfiddle, when I try it locally, I get the following error during the first push to addContact: Uncaught TypeError: Cannot read property 'length' of undefined jQuery.jQuery.extend._Deferred.deferred.resolveWithjquery-1.5.1.js:869 donejquery-1.5.1.js:6591 jQuery.ajaxTransport.send.callbackjquery-1.5.1.js:7382 Ideas?

    - by Nimbuz
    HTML: <a href="#" rel="tooltip">Open Tooltip</a> <div id="tooltip">Tooltip Content</div> I checked out some tooltip plugins but my requirement is a really basic tooltip that shows a hidden div on hover. All plugins either have too many advanced options that I don't require and have already styled tooltips that might be difficult to modify. I'd appreciate any help. Thanks.

  • Can this jQuery code snippet be shortened?

    - by David Vidmar
    I have just stared using jQuery and although following code gets the job done, I have a feeling that it can be shortened. var accountAddress = $(document.createElement("input")).addClass("readOnly").attr("contentEditable", "false").attr("id", "d_accountAddress"); $("#customerid_c").next().next().next().append(accountAddress); If it is not clear - what I'm doing is creating new input tag, assigning class and making it readonly, then positioning new input two TD's to the right of some known text.

  • Faking Fixed Position in IE6

    - by Andrew
    I have a site that utilizes a bottom fixed position masthead here: http://www.entheospartners.com/newsite/ This setup works great in all browsers except IE6, which doesn't support fixed positioning in the least, so here's what I've done: When an IE6 user comes to the page, I make the determination if scrolling is necessary using this bit of code: var windowHeight = $(window).height(); var totalHeight = windowHeight - 100; // where 100 is the sum of the top nav height + footer height var contentHeight; if($('#subpage-content-small').length) { // main content div for a three column layout contentHeight = $('#subpage-content-small').height(); }; if($('#subpage-content-wide').length) { // main content div for a two column layout contentHeight = $('#subpage-content-wide').height(); }; if(contentHeight > totalHeight) { $('#container-container').css({ 'overflow-y' : "scroll", 'height' : totalHeight }); }; ...which calculates everything correctly, puts the scrollbars where they need to be (flush right), and sets them to the appropriate height. The problem is that the scrollbars don't move the content. I can't say that I've ever seen anything quite like this before, so I'm hoping someone else on here has. Thanks in advance! PS - Obviously, this needs to be looked at in IE6 for troubleshooting, which I know will be as painful for you as it is for me.

  • jQuery: Self Executing Plugin?

    - by GnrlBzik
    I am working on expansion of my jQuery plug-in authoring knowledge, just playing around with my own ideas for learning benefits. So i was wondering how you guys tackle the need of plugin executing without any user specific input. So I have a need for plug-in that executes right away after document is ready, without any user's specific input just as long as doc is loaded, so the only way I see how to execute plug-in on it's own is to attach handler to ready listener that executes my function which I extended the jQuery with. And because this needs to be self enclosed, part of the code, I attach handler to event listener within the function. So how else could one tackle this? Any take at this is appreciated. Thank you in advance everyone.

  • Save jQuery callback functions in a separate file

    - by Danny Herran
    Probably I missed something, but lets say I have this: $('a.delete').click(function(){ resp=window.confirm("Are you sure you want to delete this?"); if(resp) return true; else return false; } Now, I want to save that callback function into a separate js file, because I will use it in several pages. My logic told me to do this: $('a.del').click(delete_element()); Having my js file like this: function delete_element(){ resp=window.confirm("Are you sure you want to delete this?"); if(resp) return true; else return false; } This doesn't work. Everytime my page loads, it displays the confirm window, even if I haven't clicked the link. It is clear that my logic failed this time. What am I missing?

  • Text box loses focus when DIV is hovered

    - by Konoplianko
    Hello. I have a problem: When I enter a text into suggestion text box, popup panel appears. But when user places mouse over this popup panel with suggestions - text box loses focus. What should I do to prevent losing focus ? Example which have the same behaviour: http://demo.raibledesigns.com/gwt-autocomplete/ Thanks for any help. Update 1 SuggestionMenu which is being shown is extending MenuBar which sets focus for all menu items. void itemOver(MenuItem item, boolean focus) { if (item == null) { // Don't clear selection if the currently selected item's menu is showing. if ((selectedItem != null) && (shownChildMenu == selectedItem.getSubMenu())) { return; } } // Style the item selected when the mouse enters. selectItem(item); if (focus) { focus(); } // If child menus are being shown, or this menu is itself // a child menu, automatically show an item's child menu // when the mouse enters. if (item != null) { if ((shownChildMenu != null) || (parentMenu != null) || autoOpen) { doItemAction(item, false); } } } It's clear that i cant fix loosing focus. Now question is - how to make on pressing backspace or any key to focus on edit box? Thanks in advance

  • jQuery rotator not rotating properly - too much recursion

    - by Matt Nathanson
    I've built a custom jQuery rotator using just basic animation to rotate the 3 Divs (images). I've built the function and then reinitiate the function using it as a call back. Here's the code: function ImageRotate() { var CurrentFeature = "#container" + featureNumber; $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); var featureNumber2 = featureNumber-1; if ( featureNumber == 1) {featureNumber2=3} var CurrentFeature2 = "#container" + featureNumber2; $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '0px'}, 3000); $('#container2').stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); var featureNumber3 = featureNumber+1; if ( featureNumber == 3){featureNumber3=1} var CurrentFeature3 = "#container" + featureNumber3; $(CurrentFeature3).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); if (featureNumber ==1) {featureNumber=3} else{featureNumber--}; $(CurrentFeature).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature3).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature2).stop(false, false).delay(4500).animate({'top' : '-330px'}, 25,ImageRotate()); }; It's worth noting that when calling the function again I also tried making another function called ImageRotate2(); and it did the same thing. It loops, but i get all sorts of funkiness. Edit: I've also tried some answers in the replies and they both leave me with recursion errors each second.

  • Can jQuery animate() behave differently for specific elements within my selection?

    - by Sune Rasmussen
    I have a selection of elements in a jQuery object. I want to animate their font sizes, but as I have both the headlines and various paragraphs in the selection, they should be animated slightly differently, as the headlines should end up with a larger font size than the paragraphs. I already have this information stored in the jQuery data cache. I can do that. But, not unless I use several calls to the animate function, one for each specific, slightly different animation, perhaps using event triggering or setTimeout() calls. Of course I want to avoid this, as it's damn ugly and an odd way around. Much prettier if it could be done internally, within the animation ... Any help would be much appreciated.

  • Jquery Ignore Event

    - by HealthWarning
    I'll just go straight to the point. Let's say we have this markup: <span href="">Text <a href="">Link</a></span> We have events bound to both elements. How do I make it such that when I click on the anchor tag, the event on the parent will not be triggered? I've tried using the Jquery method stopPropagation() but still no luck. Any thoughts? Thanks.
