• How to make a jquery datePicker button image unclickable

  - by Farzana

  I have a jquery UI datePicker in my page. I have a text box on which the date is displayed. The code is: $("#cal").datepicker({ minDate: new Date(), defaultDate: new Date(), buttonImage: '/images/calendar.gif', constrainInput: false, closeText: 'Close', showButtonPanel: true, showButtonText: 'Choose a date', buttonImageOnly : true, showOn : 'button' }); $("#till").datepicker('setDate', today); I want to disable this on some conditions. I use the following code to disable: $("#cal").datePicker('disable'); It blacks out the text box but the image is still clickable. The problem is in IE, the date picker pop up comes up but does not close when the image button associated with the date picker is clicked. I also tried to bind a onclick function with the image to make it non-clickable. But that does not work as well. How can make the date picker image button non-clickable when the date picker is disabled. Any help would be appreciated. Thanks, Farzana

• Making a jQuery plugin work on all objects

  - by Jon Winstanley

  I am using the jQuery physics plugin for a pet project I am working on. The plugin enables the moving of DOM objects in realistic ways using velocity, gravity, wind etc. However I want to use the plugin to calculate where objects are to be placed inside a canvas element, not DOM objects. How do I change the plugin script functions to work on any object with 'top' and 'left' properties rather than only working with DOM objects: Currently the script functions look like this: jQuery.fn.funname = function() { return this; };

• Jquery load DIV inside another DIV at same page

  - by Sergio

  HTML: <div class="someclass" rel="first">text 1</div> <div class="someclass" rel="second">text 2</div></div></div> <div class="info_ly">here is some text</div> <div class="first" > the first DIV </div> <div class="second" > the second DIV </div> CSS: .first{ display:none} .second{ display:none} Jquery: $(".someclass").click(function() { $(".info_ly").html($(this).attr('rel')); }); I want to call and load the "rel" DIV inside "info_ly" DIV. With this Jquery code I get only text "first" or "second" inside "info_ly" DIV. How can I load the DIV with the class "first" or DIV with the class "second" inside "info_ly" DIV?

• SQL CLR and nullable datetime parameter

  - by toluca70

  I'm trying to write a SQLCLR function that takes a DateTime2 as input and returns another DateTime2. Based on this post I altered the parameter to be the C# type DateTime giving me the level of precision I require. However because the input can be null I would like it to be DateTime?; the return type as well. using System; using Microsoft.SqlServer.Server; namespace SqlServer.Functions { public class UserDefinedFunctions { [SqlFunction(DataAccess = DataAccessKind.None)] public static DateTime? GetLocalTimeFromGMT(DateTime? dateTime) { if (dateTime.HasValue) return DateTime.SpecifyKind(dateTime.Value, DateTimeKind.Utc).ToLocalTime(); else return (DateTime?)null; } } } The problem is I get the following error when I try to deploy: Error 1 Cannot find the type 'Nullable`1', because it does not exist or you do not have permission. SqlServer.Functions I'm using Sql Server 2008 and Visual Studio 2008.

• How can you set a time limit for a PowerShell script to run for?

  - by calrain

  I want to set a time limit on a PowerShell (v2) script so it forcibly exits after that time limit has expired. I see in PHP they have commands like set_time_limit and max_execution_time where you can limit how long the script and even a function can execute for. With my script, a do/while loop that is looking at the time isn't appropriate as I am calling an external code library that can just hang for a long time. I want to limit a block of code and only allow it to run for x seconds, after which I will terminate that code block and return a response to the user that the script timed out. I have looked at background jobs but they operate in a different thread so won't have kill rights over the parent thread. Has anyone dealt with this or have a solution? Thanks!

• Can jQuery UI's Sortable handle complex selectors for the items option?

  - by jverdi

  I have list items in an unordered list that when double clicked, can be edited in place via a wysiwyg editor. $('ul.mtm_section').sortable({ disabled: true, distance: 10, items: '> li:not(:has(form))' }); My goal is to prevent the list item from being sorted while it is being edited - aka once a form element has been swapped in place of the contents. Unfortunately my selector for items is not working. Is sortable able to handle complex selectors like these? If not, are there other clever means to disable some items from being sortable, perhaps a callback function? I would prefer to rely on this sortable option, as the wysiwyg plugin is deeply nested with jEditable and as far as I know does not open up any events for me to hook into. Using jQuery 1.4.2 and jQuery UI 1.8.1

• Autorelease for CGMutablePathRef?

  - by huggie

  Hi, I am developing for iphone. I want to creating a mutable path via CGPathCreateMutable(), and I want to return it out of the function which creates it. I'm suppose to call a CGPathRelease() when I'm done with it. But since I'm returning it I wish to autorelease it. Since Quartz path is a C code (and doesn't look like an objective C object), is it correct that I cannot call autorelease on it? Edit: For others who stumble upon this question, the below advise is for C functions returning Core foundation objects only. For objective C methods returning Core foundation objects, see http://stackoverflow.com/questions/2901942/ownership-regarding-to-returned-quartz-objects

• Passing a JavaScript variable to a helper method

  - by Brendan Vogt

  I am using ASP.NET MVC 3 and the YUI library. I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such: window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))'; Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like: var formatActionLinks = function (oCell, oRecord, oColumn, oData) { var newsId = oRecord.getData('NewsId'); oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>'; };

• Adding hover trigger from another div

  - by jakeprzespo

  I am trying to activate the native hover effect of a div from another div. I understand that I could do this all in jQuery and add the styles in there, but would rather leave the native :hover in the CSS. I'm just wondering if there is a way for this to work: $("#div1").live("mouseenter", function() { $("#div2").trigger("mouseenter"); }); I'd like to call it by doing something like this, but it isn't working. Is there really no way to trigger an event from another element's event? Thanks in advance.

• Fire only one Custom Validator at a time

  - by Lijo

  I have two Custom Validators attached to a textbox. The textbox is to enter comma separated list of emails. The first validator checks that there is not duplicate email address. The second custom validator checks that all the email addresses are in valid format. I have following code and it works fine. However, when both the failure criteria is met both of them are firing and I get two * at the right side of my textbox. What is the best approach to show only one * at a time? CODE <asp:CustomValidator ID="valEmailRecipients" runat="server" ControlToValidate="txtEmailRecipients" ClientValidationFunction="isUniqueElements" OnServerValidate="IsUniqueEmail_Validate" Text="*" ErrorMessage="There should be no duplicate email address for a report" ValidationGroup="Save"> </asp:CustomValidator> <asp:CustomValidator ID="valEmailFormat" runat="server" ControlToValidate="txtEmailRecipients" ClientValidationFunction="checkEmailFormat" OnServerValidate="IsValidEmailFormat_Validate" Text="*" ErrorMessage="Entries should be valid email addresses separated by comma" ValidationGroup="Save"> </asp:CustomValidator> REFERENCES: Validating with a Custom Function for ASP.NET Server Controls

• ASP.NET Controls Not Recognized

  - by Liam

  I just installed the release version of Visual Studio 2010, and it looks like there's something wrong with the standard ASP.NET server controls. When I create a basic server control, such as a TextBox, the editor underlines it in green and says (I also get no intellisense for ASP.NET controls): Element 'TextBox' is not a known element. This can occur if there is a compilation error in the Web site, or the Web.config file is missing. The web site builds fine, and the Web.config file is not missing: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="false" targetFramework="4.0" /> </system.web> </configuration> The controls work just fine in the code-behind, and they function correctly when I run the site. Is there some configuration problem here?

• How can I detect 'any' ajax request being completed using jQuery?

  - by Brian Scott

  I have a page where I can insert some javascript / jquery to manipulate the output. I don't have any other control over the page markup etc. I need to add an extra element via jquery after each present on the page. The issue is that the elements are generated via an asynchronous call on the existing page which occurs after $(document).ready is complete. Essentially, I need a way of calling my jquery after the page has loaded and the subsequent ajax calls have completed. Is there a way to detect the completion of any ajax call on the page and then call my own custom function to insert the additional elements after the newly created s ?

• Using eval() in Javascript to unpack the array

  - by gnomixa

  I have an array that I need to unpack. So, from something like var params = new Array(); params.push("var1"); params.push("var2"); I need to have something like "var1", "var2". I tried using eval, but eval() gives me something like var1, var2...i don't want to insert quotes myself as the vars passed can be integers, or other types. I need to pass this to a function, so that's why i can't just traverse the array and shove it into a string. What is the preferred solution here?

• How to detect unresolved symbol when creating a library ?

  - by Simon

  Hello everyone, Under Solaris 10, I'm creating a library A.so that calls a function f() which is defined in library B.so. To compile the library A.so, I declare in my code f() as extern. Unfortunately, I "forgot" to declare in A's makefile that it has to link with B. However, "make A" causes no warning, no error, and the library A.so is created. Of course, when executing A's code, the call of f() crashes because it is undefined. Is there a way (linker option, code trick...) to make the compilation of library A fail ? How can I be sure that all symbols refered to in library A are defined at compile time ? Thanks for any suggestions.

• Resetting Objects vs. Constructing New Objects

  - by byronh

  Is it considered better practice and/or more efficient to create a 'reset' function for a particular object that clears/defaults all the necessary member variables to allow for further operations, or to simply construct a new object from outside? I've seen both methods employed a lot, but I can't decide which one is better. Of course, for classes that represent database connections, you'd have to use a reset method rather than constructing a new one resulting in needless connecting/disconnecting, but I'm talking more in terms of abstraction classes. Can anyone give me some real-world examples of when to use each method? In my particular case I'm thinking mostly in terms of ORM or the Model in MVC. For example, if I would want to retrieve a bunch of database objects for display and modify them in one operation.

• Can't register 32bit dll under 64bit windows

  - by Wodzu

  Hi guys. I try to create a COM object from my JS script like this: function main() { var MyApplication = new ActiveXObject("Base.Application"); } main(); I am getting error: "Automation server can't create object". This error occurs on Windows 2003 64 bit. The dll is 32 bit and it works fine on 32 bit systems. I've tried both versions of Regsvr32.exe on the 64 bit system and both versions told me that dll registered succesfully. Unfortunatelly the error message does not tell me why it can not create object. The reason is unknown, it might be that it can't create object because it is still not registered or it might be something totally different... I've also add full permisions to this dll. I don't know what else I can do, do you have any ideas?

• Why can't I access a const vector with iterator?

  My example is as below. I found out the problem is with "const" in function void test's parameter. I don't know why the compiler does not allow. Could anybody tell me?

• Javascript parent page redirection from iframe.

  - by Danil

  Hello to all. I need to implement parent page redirection from iframe. I know that it is impossible to do in different domains due to browsers security. However I found that links have target attribute and tried to use it in the following way: <a href="http://google.com" target="_top" id="testParentRedirect">someLink</a> It works fine if I click this link manually, but I couldn't find cross-browser solution to simulate it using javascript. document.getElementById('testParentRedirect').click(); This works fine in IE, however Firefox and Safary don't know click function :). I tried to work with jquery, but for some reason they don't simulate click event for links. (see following post) I couldn't find any appropriate solution on stackoverflow. Maybe someone could help me in it. I will appreciate it. :)

• Multiple webservice calls

  - by Mujtaba Hassan

  I have a webservice (ASP.NET) deployed on a webfarm. A client application consumes it on daily basis. The problem is that some of its calls are duplicated (with difference of milliseconds). For example I have a function Foo(string a,string b). The client app calls this webmethod as Foo('test1','test2') once but my log shows that it is being called twice or sometimes 3 or 4 times randomly. Is this anything wrong with the webfarm or the code? Note that the webmethod has simple straighfarward insert and update statements.

• Showing same dfp ads in a single page web application

  - by mivaas19

  I have a single page web application which contains dfp ads. I have two dfp adunits that Iam firing and they are placed in between the content which is a list of articles for a particular category. When I click on another category,it just loads articles for different category(doesnt change the url in address bar) and triggers the same ads. So this is like triggering the ads on the same page. The ads dont show up the second time and this is because you cant use the same adunits on the same page. Since I cannot use the refresh function provided by dfp since my DOM is reconstructed everytime, is there any way I can do this?.

• R webscraping: interrogating for date and importance

  - by adam.888

  I am able to webscrape a table from a webpage containing news library(XML) webpage <- "http://www.tradingeconomics.com/calendar" tables <- readHTMLTable(webpage ) n.rows <- unlist(lapply(tables, function(t) dim(t)[1])) dfcal <- as.data.frame(tables$calendar) However I do not know how to interrogate for date or for importance. For example how could I webscrape news from Jan 2014? I am able to do this on the webpage by altering button settings, but how can I do it from within R? I was also not able to collect the importance column data. Also are there better ways for collecting economic news from within R? I have looked on http://www.rseek.org/ but could not find anything. Thank you for your help.
