  • Controlled hyperlink hijaxing

    - by Izmoto
    I am working on a web application. I have a data grid with a 'commands' column that has hyperlinks for some common CRUD operations (Edit, Delete, etc). When a user clicks on say the Edit hyperlink, I retrieve the unique identifier for the data grid row and load a modal form dialog (i am using jQuery UI) so the user is able to edit the row data and subsequently close the modal form dialog at which point I refresh the page. Now, before the page is done refreshing, there's a chance that a user might click on the edit link again, and whenever that happens, 'hijaxing' fails. My question is how can i check that if a user clicks on a hyperlink and the page is refreshing, i delay until it is done refreshing, then i allow the 'hijax' to kick in.

  • how to use constants in SQL CREATE TABLE?

    - by kchiu
    Hi, I have 3 SQL tables, defined as follows: CREATE TABLE organs( abbreviation VARCHAR(16), -- ... other stuff ); CREATE TABLE blocks( abbreviation VARCHAR(16), -- ... other stuff ); CREATE TABLE slides( title VARCHAR(16), -- ... other stuff ); The 3 fields above all use VARCHAR(16) because they're related and have the same length restriction. Is there a (preferably portable) way to put '16' into a constant / variable and reference that instead in CREATE TABLE? eg. something like this would be nice: CREATE TABLE slides( title VARCHAR(MAX_TITLE_LENGTH), -- ... other stuff ); I'm using PostgreSQL 8.4. thanks a lot, and Happy New Year! cheers.

  • Filter---after setting attribute--->Servlet---after getting and setting the attribute---->Jsp How do I do this?

    - by Y.E.P
    This is what I want to do : A servlet is called.Before a servlet is called , the request is intercepted by a filter. Filter gets some details out from the request,sets them as an attribute and the forwards it to a servlet via chain.doFilter(request,response). Request finally reaches the servlet. Servlet gets the attribute set by the filter before and sets a new attribute by another name. Then it forwards it to some jsp page where the page gets the attribute and processes it. How do I do this ? I know how to write a filter and a servlet but how do I forward it to a jsp page from the servlet or is there any other way to achieve this ?

  • MediaWiki : is it possible to add an edit link in a template?

    - by leo
    I have a template on my wiki, kind of a box template. Then, there is this page where I use it several times. Can I add an edit link to each of the boxes so I don't have to edit the whole page in order to modify one of the boxes? The boxes contain only text, not other templates. Thanks! Edit: Actually there's an easier way to ask my question: Let's say I have a page without sections defined (namely without == titles ==): content A content B content C Is there a way to open an edit form only for content B?

  • Two part form in Rails

    - by samuel02
    I have some two nested resources, so that a Product can have many Bookings. On one page in a different controller I want to create a new booking and since it's a "general" booking I want a select menu to appear in a modal window where the user is able to pick one of the existing products and then go to the booking page. How can I do this? I have no problem setting up the modal and the "New booking" page is already there. What I need is a form that generates a list of existing products, picks the selected product id and then gets /products/:product_id/bookings/new . Any help appreciated! I realize my title does not describe my problem very good so better suggestions are highly welcome!

  • Enableeventvalidation in web user control

    - by Khushi
    Hi, i have a web user control containing a repeater. The repeater contains three buttons. On button click it gives the following error : Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. Since user control does not have page directive, so i changed the enableEventValidation to false, but it restricted the itemcommand event of the repeater. Can someone guide me, how to solve this problem?

  • ASP.NET MVC vs. Jquery/AJAX (Where to draw the dividing line?)

    - by punkouter
    I am learning MVC and I understand the basics now. It is very good for CRUD pages and has built in HTTP methods to post/get edits/updates. That is nice. This is all very testable by just creating a new controller and testing it. But I was thinking about other web page scenerios when using MVC. What about a page that has 2 listboxes that you add/remove users with. (A button will move the user from one listbox to another) This would be done using Jquery/Javascript... But then what happens to testing? How do you test adding/removing users from a listbox like that example? It seems to me the more jquery you use the less testable the page becomes right? When you get beyond basic forms being filled out then you need to use something more than the standard MVC pages. What is the correct philosophy on this on when am I not understanding ?

  • WMF image data validation?

    - by deostroll
    There is an image capturing device which gives its output in wmf. This output is stored in the database directly. We have cases where at times some of these images do not appear on a web page in IE. But if we right click on the page we are able to save the image on to the hard disk; meaning the image does exist on the page, but does not appear visible. I think this is because of some file corruption issue, but I don't know how to resolve it. We are however able to view such files using MS Picture Viewer (desktop app). Is there anyway we can detect such problematic files?

  • How to trigger an event ONLY if both dropdowns are selected?

    - by DaveDev
    I have a dropdown select list on my page of class="TypeFilter". I have a jQuery event that fires when a value in that list is selected. $(".TypeFilter").change(function() { // Extract value from TypeFilter and update page accordingly )); I now have to add another list to the page, and I want to implement functionality which will prevent the .change(function() from running unless both are selected. In both lists the first option in the list is some text instructing the user to select one of the items, so I was thinking of just writing some logic to test that both lists have a selected index greater than 0. I think this is a touch unclean though, especially considering that other pages that have a TypeFilter use the same logic. Is there any nifty functionality in jQuery that can do this?

  • How can I handle this kind of exceptions (in Doctrine)

    - by ppavlovic
    Can you tell me how can I handle this kind of exceptions: Fatal error: Uncaught exception 'Doctrine_Connection_Exception' with message 'PDO Connection Error: SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 110' in ... It happens when connection with MySQL is lost during query. I need to handle this exception so I can show 500 error page so the crawlers do not cache page, and to redirect user to appropriate "Try again" page. P.S. I have a lot's of code, so I can not go trough all code to put try/catch block. I need something simple and yet effective.

  • Firefox loses connection

    - by Jonno_FTW
    Hi I am using Firefox 3.5.2 and it normally works fine but then randomly it will lose connection for a few minutes, just stalling and acting as though the page is loading. I can still use Chrome and IE but FF just sits there without doing anything, not even showing the 404 or connection timeout page. Does anyone else have this problem and do they have a solution?

  • Dropdown menu getting hidden by images

    - by Bob
    I have a set of dropdown menus across the top of a web page. Below is text and some images. When I hover over the top of each menu the menu then expands below as expected but while it overlaps any text on the page it is hidden behind any images. I set the z-index to 9999 and the position is set to absolute. I found if I lower the opacity of the images to say 0.6 then the menu will overlap it. So one solution would be to detect when the menu is being hovered over and then in JavaScript or JQuery temporarily reduce the opacity of the rest of the page until the cursor moves off the menu. If so I'm not sure how to do that but is that the best approach?

  • MySql paging; "Showing result-set" of "total found" help

    - by Camran
    I need a formula for showing results on my classifieds website. I am now done with the paging of records, but this formula for showing results remains. I want it like this: Showing 1-50 of 123 found. Now what is the formula for this? I have these variables which should be enough I think: $results_per_page = 50; //results per page $page = 1; //current page Also a variable called $num_total contains the total nr of hits, in this case 123. Thanks

  • javascript "window.history.forward(1);" not working.

    - by Ray L.
    Hi, I'm trying to prevent the back button from working on one of my asp.net mvc pages. I've read a couple of places that if i put "window.history.forward(1);" in my page it will prevent the back button from working on a given page. This is what I did in my page: <script type="text/javascript"> $(document).ready(function () { window.history.forward(1); }); </script> It doesn't seem to be working. Am I using this incorrectly or is this approach wrong? thanks.

  • Targeting an iFrame once with jQuery

    - by user275074
    Hi, I have a series of frames (4) which are used in a page to create loading of dynamic content through Ajax calls. In each of these frames I target parent level elements and update them with there respective content e.g. $("#loadingGrid1",top.document).show(); $("#frameSkills",top.document).hide(); In jQuery is there a way to instead of targeting specific elements on the parent page multiple times, simply target the page once into a variable e.g. var parentPage=$('#frameSkills',top.document); And then use this variable to apply content like $(parentPage #loadingGrid1).hide() Hope I've explained what I'm after enough. Basically, I'm having to call "top.document" in every jQuery selector I make and it seems like a waste of energy.
