  • User Interface functionality modelling languages?

    - by naugtur
    I am looking for a UI functionality modelling language (UML-alike "thing", but for user interfaces) that is already accepted and maybe has its design patterns and handles the problem better than state or activity diagram. (If there is no such thing I'm planning to develop that BTW :)) This question came to mind as a result of a discovery that UML and its diagrams fails at describing complicated UI functionality with event-driven flow of execution (ie. javascript/jQuery big projects) EDIT: I've been thinking of using BPMN but It was not created for this purpose. EDIT2: See this community topic of mine - I decided to start developing said language.

  • Call click event on last clicked row in YUI datatable

    - by Javi
    Hello, I have a YUI datatable and I have a function which is invoked when I click on a row: ... YAHOO.keycoes.myDatatable = myDatatable; ... myDatatable.subscribe("rowClickEvent", oneventclickrow); var oneventclickrow = function( args ) { ... } I'd like to invoke the function subscribed to rowClickEvent on the row which is currently highlighted in the datatable (the row which was clicked for the last time). I've tried to do something like this: YAHOO.keycoes.myDatatable.getSelectedRows()[0].rowClickEvent() but getSelectedRows() doesn't return any row. How can I get the highlighted row in the datatable and then call the function associated with rowClickEvent? Thanks

  • javascript filter array of objects

    - by user441521
    I have an array of objects and I'm wondering the best way to search it. Given the below example how can I search for name = "Joe" and age < 30? Is there anything jQuery can help with or do I have to brute force this search myself? var names = new Array(); var object = { name : "Joe", age:20, email: "[email protected]"}; names.push(object); object = { name : "Mike", age:50, email: "[email protected]"}; names.push(object); object = { name : "Joe", age:45, email: "[email protected]"}; names.push(object);

  • How can I share an OnEnter event for a TcxGrid ?

    - by Roland Bengtsson
    I want to standardize the behaviour on an Devexpress TcxGrid. So I have a unit ClientData with a event: procedure TClientData.grdOnEnter(Sender: TObject); begin mnuCxGridStandardMenu.Grid := TcxGrid(Sender); end; If I try to use that event from a TcxGrid.OnEnter event in another unit it refuse to work. If I paste in ClientData.grdOnEnter then a dialog says it is not an valid identifier. Is it possible to share an event for several units in Delphi 2007 ?

  • ModalPopupExtender OnShow Event

    - by Thomas
    When clicking a button, I have a ModalPopupExtender (Panel) that gets displayed. I can't seem to trigger any event during that process. Adding an event to the button that opens the ModalPopupExtender doesnt work, as it never triggers. Adding the button as a trigger in my UpdatePanel also doesnt work. Scenario: I have a gridview with a button outside of the gridview. Clicking the button opens up a ModalPopupExtender which needs to display the checkboxes clicked on the gridview. I have the code to get the checkboxes clicked on the Gridview, however I cant seem to use an event during the process of opening the ModalPopupExtender.

  • Graph visualization code in javascript?

    - by Chris Farmer
    Hi. I have a data structure that represents a directed graph, and I want to render that dynamically on an HTML page. Does anyone know of any javascript code that can do a reasonable job with graph layout? These graphs will usually be just a few nodes, maybe ten at the very upper end, so my guess is that performance isn't going to be a big deal. Ideally, I'd like to be able to hook it in with jQuery so that users can tweak the layout manually by dragging the nodes around. Edit: Google's Visualization API seems to be more "graphs as charts" oriented than "graphs as nodes" oriented. I didn't see any node-oriented visualizations already built there, anyway. Do you know that one exists?

  • Test whether image loaded correctly with JavaScript

    - by johkar
    I have an image deployed on several application servers (green up arrow: uparrow.gif). I have an application server status page where I list out all the servers and with a corresponding image where the image's source is the uparrow.gif for that server. If the image does not load (server down) I would like to switch to a red down arrow (downarrow.gif). Is there a way to check whether an image loaded or not with straight JavaScript (no JS libraries etc)? I would imagine I would set an interval for it to continue checking if the user were on the page. Thanks.

  • Winforms panel event after scroll

    - by Charlie boy
    Hello I have a panel in wich I do a bounch af rater complex drawing in the paint event. Since the drawing-code is kind of heavy, it gets rather twitchy when I scroll the panel, since the paint event is raised in such short intervals. My question is really this; Can i capture evnts such as "on scroll start" and "on scroll end" on a winforms control? If so, I could then just pause the drawing-code until the scroll is complete. Thanks in advance!

  • Apply Alloy UI 1.5 datepicker to multiple instances

    - by MyTitle
    I want to create Alloy UI datapickers on multiple form fields: <div id="date_1_wrapper"> <input type="text" class="datepick" id="date_1" /> </div> <div id="date_2_wrapper"> <input type="text" class="datepick" id="date_2" /> </div> Using JQuery I can do it using following code: $('.datepick').each(function(){ $(this).datepicker(); }); But how to achieve same functionality in Alloy UI? For now I use following code, but this code apply DatePickers by ID, not by CSS class in loop: AUI().use( 'aui-datepicker', function(A) { new A.DatePicker ( { calendar: { dateFormat: '%d/%m/%Y' }, trigger: '#date_1' } ).render('#date_1_wrapper'); new A.DatePicker( { calendar: { dateFormat: '%d/%m/% }, trigger: '#date_2' } ).render('#date_2_wrapper'); } ); I think it this code can be used in beginning, but how to deal with input's and div's ID's? (A.all('.datepcik').each(function() {)

  • It's possible to don't pass in GET some fields of a form?

    - by avastreg
    I have a form with some input texts passed in GET, and i don't want to have in GET all the fields; i want to avoid empty fields. So, a concrete example for: <form method="GET" action="an_url"> <input type="text" name="field1"/> <input type="text" name="field2"/> <input type="text" name="field3"/> <input type="submit" value="submit"/> </form> I supposed that fields disabled by html attribute "disabled" shouldn't be passed to GET. So i have done a js (based on jquery) to disable empty fields on submit, something like this: $("form").submit(function() { $(this).find("input[type=text]").each( function () { if (!$.trim($(this).val())) { $(this).attr("disabled", "true"); } }); }); However, this doesn't work. Any ideas?

  • Access event.target in IE8 unobstrusive Javascript

    - by Mirko
    The following function gets the target element in a dropdown menu: function getTarget(evt){ var targetElement = null; //if it is a standard browser if (typeof evt.target != 'undefined'){ targetElement = evt.target; } //otherwise it is IE then adapt syntax else{ targetElement = evt.srcElement; } //return id of element when hovering over or if (targetElement.nodeName.toLowerCase() == 'li'){ return targetElement; } else if (targetElement.parentNode.nodeName.toLowerCase() == 'li'){ return targetElement.parentNode; } else{ return targetElement; } Needless to say, it works in Firefox, Chrome, Safari and Opera but it does not in IE8 (and I guess in previous versions as well). When I try to debug it with IE8 I get the error "Member not Found" on the line: targetElement = evt.srcElement; along with other subsequent errors, but I think this is the key line. Any help will be appreciated.

  • Jqm is not a function

    - by kris
    Hi all, I'm having some trouble with Jquery and JqModal, and I hope you are able to help, since I've been struggling for hours.. Having a single button element with an onclick action running my method "test" (shown below): $('#picture_form').jqm({ajax: '/test.php'}); $('#picture_form').jqmShow(); This will load the ajax content of test.php into my div element picture_form, shown using JqModal as its supposed to! Though when I close this window, and re-clicks the button I'm getting the error: $("#picture_form").jqm is not a function. As a solution I've tried to use the JqModal trigger function, and this leaves me able to open and close the JqModal windows as many times as I want to. Sadly I can only call the 'trigger' using test environment, in my production code I have to open the JqModal window using a function.. Does anyone have a clue why this 'bug' appears when calling the opening when using a function? Thanks in advance

  • Load first page on splashscreen using phonegap on android

    - by Syg
    Hi i'm using phonegap in conjunction with Jquery mobile. I'm trying to immediately fetch the main page, while showing the user a splashscreen. In PhoneGap for Android i'm using this super.setIntegerProperty("splashscreen", R.drawable.splash); super.loadUrl("file:///android_asset/www/index.html", 2000); While this loads the splash, it also delays the loading of index.html. It it possible to start fetching it right away? Also, if not with phonegap, has anybody done this using JQM instead of phonegap? UPDATE: After using it with a slower loading first page (doing a json request) it kinda looks like the splash screens shows for a longer period of time, so this appears to be the default behavior

  • How can I accept a hash mark in a URL via $_GET?

    - by bccarlso
    From what I have been able to understand, hash marks (#) aren't sent to the server, so it doesn't seem likely that I will be able to use raw PHP to parse data like in the URL below: index.php?name=Ben&address=101 S 10th St Suite #301 I'm looking to pre-populate form fields with this $_GET data. How would I do this with Javascript (or jQuery), and is there a fallback that wouldn't break my form for people not using Javascript? Currently if there is a hash (usually in the address field), everything after that is not parsed in or stored in $_GET.

  • organise javascript code based on page

    - by David
    Hi I am relatively new to javascript development. At the moment I have a single javascript file with lots of little misc bits of code that get called in different part of the website. For example I have an event handler for some google maps stuff that is only called on 1 single page, I have some validation stuff for my contact page etc etc. My question, is how best to organise this code - given that each page only requires very little code but its different and specific per page? Oh, I am using jquery if that makes a difference.

  • Attaching an event to an Iframe that contains more iframes

    - by Oscar Godson
    I have an editor which is in my window that contains a wrapping iframe and then 2 more iframes inside like (the HTML inside the <iframe> element is inserted via write() in JS, not hardcoded like this): <iframe class="parent"> <div class="wrapper"> <iframe class="editor"></iframe> <iframe class="previewer"></iframe> </div> </iframe> One is an editor, the other is a previewer. The first one that contains the two (we'll call this the parent) has an eventListener for mousemove attached to it, but nothing is firing. If i add a 5px border for example, the event will fire when I move my mouse on the border of the parent, but not when i hover over the middle which contains the editor or previewer (previewer is display:none while the editor is visible, and vice versa). So, the blue area in the following i can mousemove, but the rest I can't. It's most likely because of the stacking order, but how can I attach an event to fire on the entire frame? I need mousemove because on mousemove I display a menu in the bottom right. I want the same menu to display whether or not the editor or the previewer is visible.

  • form change with javascript

    - by aslum
    I have two drop down lists <select name="branch"> <option value="b">Blacksburg</option> <option value="c">Christiansburg</option> <option value="f">Floyd</option> <option value="m">Meadowbrook</option> </select> but I would like the second list to be different based upon what is selected from the first list. So FREX Blacksburg's might be <select name="room"> <option value="Kitchen">Kitchen Side</option> <option value="Closet">Closet Side</option> <option value="Full">Full Room</option> </select While Christiansburg's is <select name="room"> <option value="Window">Window Side</option> <option value="Door">Door Side</option> <option value="Full">Full Room</option> and of course the options are also different for the other branches... Is it possible to change the second drop down list based on what they select for the first one? I have used javascript a teensy bit, but not much so please explain in detail. Thanks!
