  • Regex-expression with danish characters

    - by timkl
    I'm currently trying to wrap my head around regex, I have a validation snippet that tests an input box against a regex-expression: $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z]*$/).test(value); }, "Some text"); That works well, but when I try to add a space and some special danish characters, it doesn't filter the danish characters, only the space. $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z æøåÆØÅ]*$/).test(value); }, "Some text"); Any ideas to what could be wrong?

  • jQuery plugin: Colorpicker

    - by New Developper
    Hey all, I'm using this colorpicker (http://www.eyecon.ro/colorpicker) and am trying to capture the hex value so that I can use it on the server side to store the selected color. If you check out the link provided, I'm using the last option: $('#colorSelector').ColorPicker({ color: '#0000ff', onShow: function (colpkr) { $(colpkr).fadeIn(500); return false; }, onHide: function (colpkr) { $(colpkr).fadeOut(500); return false; }, onChange: function (hsb, hex, rgb) { $('#colorSelector div').css('backgroundColor', '#' + hex); } }); My problem is that I can't seem to get the hex value from it...I've tried simply calling the name of the input to get its value, but it won't work (when you click away to make the colorpicker disappear, the input changes to 'style="display:none;"' so I can't get anything from it. Then, I tried pulling the value using some simple jQuery calls, but got nothing... Please help....

  • IComparable not included when serializing in WCF

    - by djerry
    Hey guys, I have a list i'm filling at server side. It's a list of "User", which implements IComparable. Now when WCF is serializing the data, i guess it's not including the CompareTo method. This is my Object class : [DataContract] public class User : IComparable { private string e164, cn, h323; private int id; private DateTime lastActive; [DataMember] public DateTime LastActive { get { return lastActive; } set { laatstActief = value; } } [DataMember] public int Id { get { return id; } set { id = value; } } [DataMember] public string H323 { get { return h323; } set { h323 = value; } } [DataMember] public string Cn { get { return cn; } set { cn = value; } } [DataMember] public string E164 { get { return e164; } set { e164 = value; } } public User() { } public User(string e164, string cn, string h323, DateTime lastActive) { this.E164 = e164; this.Cn = cn; this.H323 = h323; this.LastActive= lastActive; } [DataMember] public string ToStringExtra { get { if (h323 != "/" && h323 != "") return h323 + " (" + e164 + ")"; return e164; } set { ;} } public override string ToString() { if (Cn.Equals("Trunk Line") || Cn.Equals("")) if (h323.Equals("")) return E164; else return h323; return Cn; } public int CompareTo(object obj) { User user = (User)obj; return user.LastActive.CompareTo(this.LastActive); } } Is it possible to get the CompareTo method to reach the client? Putting [DataMember] isn't the solution as i tried it ( i know...). Thanks in advance.

  • How to rename an existing Grails application

    - by Johan Pelgrim
    Hi there, Does anybody know how to (easily) "rename" an existing grails application? I'm running into this because my PaaS provider does not allow me to delete a subscription... So I want to deploy my application under a different name. Of course, I can do this manually, but I think it might be a useful 'top-level' script (i.e. "grails rename-app newappname") Manual hints: When I do a "grails create-app myappname" I can see the myappname exists in the following files (and filenames)... Of course this is done by the create-app script, which replaces @...@ tokens in the template. I guess once they are replaced, it's not trivial to do a rename. ./.project: <name>myappname</name> ./application.properties:app.name=myappname ./build.xml:<project xmlns:ivy="antlib:org.apache.ivy.ant" name="myappname" default="test"> ./ivy.xml: <info organisation="org.example" module="myappname"/> ./myappname-test.launch:<stringAttribute key="org.eclipse.jdt.launching.PROJECT_ATTR" value="myappname"/> ./myappname.launch:<listEntry value="/myappname"/> ./myappname.launch:<listEntry value="<?xml version="1.0" encoding="UTF-8"?> <runtimeClasspathEntry containerPath="org.eclipse.jdt.launching.JRE_CONTAINER" javaProject="myappname" path="1" type="4"/> "/> ./myappname.launch:<stringAttribute key="org.eclipse.jdt.launching.PROJECT_ATTR" value="myappname"/> ./myappname.launch:<stringAttribute key="org.eclipse.jdt.launching.VM_ARGUMENTS" value="-Dbase.dir="${project_loc:myappname}" -Dserver.port=8080 -Dgrails.env=development"/> ./myappname.tmproj: <string>myappname.launch</string> And of course... the top-level directory name is "myappname" Any hints, or information about ongoing initiatives in this area are welcome Greetz, Johan

  • Can't set Visible attribute in ASP.NET Panels

    - by RichW
    I am having trouble with visible attribute of an ASP.NET Panel control. I have a page that calls a database table and returns the results in a datagrid. Requirements If some of the returned values are null I need to hide the image that's next to it. I am using a Panel to determine whether to hide or show the image but am having trouble with the statement: visible='<%# Eval("addr1") <> DBNull.Value %>' I have tried these as well: visible='<%# Eval("addr1") <> DBNull.Value %>' visible='<%# IIf(Eval("addr1") Is DbNull.Value, "False","True") %>' Code is below: <asp:TemplateField > <ItemTemplate> <%# Eval("Name")%> <p> <asp:Panel runat="server" ID="Panel1" visible='<%# Eval("addr1") <> DBNull.Value %>'> <asp:Image Id="imgHouse" runat="server" AlternateText="Address" SkinId="imgHouse"/> </asp:Panel> <%# Eval("addr1") %><p> </ItemTemplate> </asp:TemplateField> What am I doing wrong?

  • Unable to execute stored Procedure using Java and JDBC

    - by jwmajors81
    I have been trying to execute a MS SQL Server stored procedure via JDBC today and have been unsuccessful thus far. The stored procedure has 1 input and 1 output parameter. With every combination I use when setting up the stored procedure call in code I get an error stating that the stored procedure couldn't be found. I have provided the stored procedure I'm executing below (NOTE: this is vendor code, so I cannot change it). set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER PROC [dbo].[spWCoTaskIdGen] @OutIdentifier int OUTPUT AS BEGIN DECLARE @HoldPolicyId int DECLARE @PolicyId char(14) IF NOT EXISTS ( SELECT * FROM UniqueIdentifierGen (UPDLOCK) ) INSERT INTO UniqueIdentifierGen VALUES (0) UPDATE UniqueIdentifierGen SET CurIdentifier = CurIdentifier + 1 SELECT @OutIdentifier = (SELECT CurIdentifier FROM UniqueIdentifierGen) END The code looks like: CallableStatement statement = connection .prepareCall("{call dbo.spWCoTaskIdGen(?)}"); statement.setInt(1, 0); ResultSet result = statement.executeQuery(); I get the following error: SEVERE: Could not find stored procedure 'dbo.spWCoTaskIdGen'. I have also tried CallableStatement statement = connection .prepareCall("{? = call dbo.spWCoTaskIdGen(?)}"); statement.registerOutParameter(1, java.sql.Types.INTEGER); statement.registerOutParameter(2, java.sql.Types.INTEGER); statement.executeQuery(); The above results in: SEVERE: Could not find stored procedure 'dbo.spWCoTaskIdGen'. I have also tried: CallableStatement statement = connection .prepareCall("{? = call spWCoTaskIdGen(?)}"); statement.registerOutParameter(1, java.sql.Types.INTEGER); statement.registerOutParameter(2, java.sql.Types.INTEGER); statement.executeQuery(); The code above resulted in the following error: Could not find stored procedure 'spWCoTaskIdGen'. Finally, I should also point out the following: I have used the MS SQL Server Management Studio tool and have been able to successfully run the stored procedure. The sql generated to execute the stored procedure is provided below: GO DECLARE @return_value int, @OutIdentifier int EXEC @return_value = [dbo].[spWCoTaskIdGen] @OutIdentifier = @OutIdentifier OUTPUT SELECT @OutIdentifier as N'@OutIdentifier ' SELECT 'Return Value' = @return_value GO The code being executed runs with the same user id that was used in point #1 above. In the code that creates the Connection object I log which database I'm connecting to and the code is connecting to the correct database. Any ideas? Thank you very much in advance.

  • python xml.dom.minidom.Attr question

    - by rudy
    Getting attributes using minidom in Python, one uses the "attributes" property. e.g. node.attributes["id"].value So if I have <a id="foo"></a>, that should give me "foo". node.attributes["id"] does not return the value of the named attribute, but an xml.dom.minidom.Attr instance. But looking at the help for Attr, by doing help('xml.dom.minidom.Attr'), nowhere is this magic "value" property mentioned. I like to learn APIs by looking at the type hierarchy, instance methods etc. Where did this "value" property come from?? Why is it not listed in the Attr class' page? The only data descriptors mentioned are isId, localName and schemaType. Its also not inherited from any superclasses. Since I'm new to Python, would some of the Python gurus enlighten?

  • What's the order of execution when using IDataErrorInfo?

    - by Benny Jobigan
    Many times with WPF, we use INotifyPropertyChanged and IDataErrorInfo to enable binding and validation on our data objects. I've got a lot of properties that look like this: public SomeObject SomeData { get { return _SomeData; } set { _SomeData = value; OnPropertyChanged("SomeData"); } } Of course, I have an appropriate overridden IDataErrorInfo.this[] in my class to do validation. Question 1) In a binding situation, what happens? For example: User enters new data. Binding writes data to property. Property set method is executed. Binding checks this[] for validation. If the data is invalid, the binding sets the property back to the old value. Property set method is executed again. This is important if you are adding "hooks" into the set method, like: public string PathToFile { get { return _PathToFile; } set { if (_PathToFile != value && // prevent unnecessary actions OnPathToFileChanging(value)) // allow subclasses to do something or stop the setter { _PathToFile = value; OnPathToFileChanged(); // allow subclasses to do something afterwards OnPropertyChanged("PathToFile"); } } }

  • Drupal 7: File field causes error with Dependable Dropdowns

    - by LoneWolfPR
    I'm building a Form in a module using the Form API. I've had a couple of dependent dropdowns that have been working just fine. The code is as follows: $types = db_query('SELECT * FROM {touchpoints_metric_types}') -> fetchAllKeyed(0, 1); $types = array('0' => '- Select -') + $types; $selectedType = isset($form_state['values']['metrictype']) ? $form_state['values']['metrictype'] : 0; $methods = _get_methods($selectedType); $selectedMethod = isset($form_state['values']['measurementmethod']) ? $form_state['values']['measurementmethod'] : 0; $form['metrictype'] = array( '#type' => 'select', '#title' => t('Metric Type'), '#options' => $types, '#default_value' => $selectedType, '#ajax' => array( 'event' => 'change', 'wrapper' => 'method-wrapper', 'callback' => 'touchpoints_method_callback' ) ); $form['measurementmethod'] = array( '#type' => 'select', '#title' => t('Measurement Method'), '#prefix' => '<div id="method-wrapper">', '#suffix' => '</div>', '#options' => $methods, '#default_value' => $selectedMethod, ); Here are the _get_methods and touchpoints_method_callback functions: function _get_methods($selected) { if ($selected) { $methods = db_query("SELECT * FROM {touchpoints_m_methods} WHERE mt_id=$selected") -> fetchAllKeyed(0, 2); } else { $methods = array(); } $methods = array('0' => "- Select -") + $methods; return $methods; } function touchpoints_method_callback($form, &$form_state) { return $form['measurementmethod']; } This all worked fine until I added a file field to the form. Here is the code I used for that: $form['metricfile'] = array( '#type' => 'file', '#title' => 'Attach a File', ); Now that the file is added if I change the first dropdown it hangs with the 'Please wait' message next to it without ever loading the contents of the second dropdown. I also get the following error in my JavaScript console: "Uncaught TypeError: Object function (a,b){return new p.fn.init(a,b,c)} has no method 'handleError'" What am I doing wrong here?

  • setlocale to fr-FR in PHP and number formatting

    - by bateman_ap
    Hi, I am trying to create a French version of one of my sites. I have set setlocale(LC_ALL, 'fr_FR'); at the top of my page, and using strftime I am displaying dates correctly in the French style. However I am having some problems with a number. Part of the page uses data I am getting from a Web Service. I am assigning a returned value to a var like this: $overallRating = $returnArray['Overall']; I am then using the following code later to format it to 1 decimal place number_format($overallRating,1) In the English version the overallRating value might be 7.5 and returns a value such as 7.5 (the reason for running it through the number_format is if it returns 7 I want it to display 7.0) However in the French version if I print out the raw $overallRating value I get 7,5 which looks like it has translated it into french. This would be fine but if I run it through number_format I get the error: Notice: A non well formed numeric value encountered in /sites/index.php on line 250 Line 250 is the number_format line I presume the translation to 7,5 is messing it up, but not sure how to solve this... Using PHP 5.3 in case there is anything new that helps me

  • rich suggestions - why input is null? (seam framework)

    Hi, I'm trying to build a rich suggestions and i do not understand WHY the input value is null... I mean, why inputText value is not taken when i enter something. The .xhtml code: <h:inputText value="#{suggestion.input}" id="text"> </h:inputText> <rich:suggestionbox id="suggestionBoxId" for="text" tokens=",[]" suggestionAction="#{suggestion.getSimilarSpacePaths()}" var="result" fetchValue="#{result.path}" first="0" minChars="2" nothingLabel="No similar space paths found" columnClasses="center" > <h:column> <h:outputText value="#{result.path}" style="font-style:italic"/> </h:column> </rich:suggestionbox> and action class: @Name("suggestion") @Scope(ScopeType.CONVERSATION) public class Suggestion { @In protected EntityManager entityManager; private String input; public String getInput() { return input; } public void setInput(final String input) { this.input = input; } public List<Space> getSimilarSpacePaths() { List<Space> suggestionsList = new ArrayList<Space>(); if (!StringUtils.isEmpty(input) && !input.equals("/")) { final Query query = entityManager.createNamedQuery("SpaceByPathLike"); query.setParameter("path", input + '%'); suggestionsList = (List<Space>) query.getResultList(); } return suggestionsList; } } So, input beeing null, suggestionList is always empty... Why input's value is not posted?

  • Read a variable from a variable cookie jquerycookie.

    - by Ozaki
    TLDR How could I tell "page.html" which one of 3 or so cookies to look at when the cookie is set on the previous page? Currently: When a link is clicked save text of link to cookie When "page.html" is loaded get the value of the cookie Loads the getjson call as per value of the cookie. E.g: <a href="page.html">link1</a> -c1 <a href="page.html">link2</a> -c2 <a href="page.html">link3</a> -c3 See previous discussion here Now that is all good and well apart from the fact if I were to say open them in multiple tabs. It changes the cookie and correctly loads the right data. But if I were to refresh one of these tabs it will load the most recently open data rather than what it should be. So if I were to save a cookie as c1 with a value of link1 c2 with a value of link2 c3 with a value of link3 How could I tell "page.html" which cookie it should be looking at, therefore not breaking the back/forward/refresh buttons on the browser when multiple tabs are open?

  • Can I use a property placeholder with Spring EL?

    - by David Easley
    Before upgrading to Spring 3 I had this in my applicationContext.xml file: <bean class="com.northgateis.pole.ws.PolePayloadValidatingInterceptor"> <property name="validateRequest" value="${validateRequest}" /> <property name="validateResponse" value="${validateResponse}" /> </bean> where ${validateRequest) and ${validateRequest) refer to properties that may or may not be defined in my properties file. In Spring 2, if these proeprties were not present in the properties file the setters on the bean were not called and so the defaults hard-coded in PolePayloadValidatingInterceptor were used. After upgrading to Spring 3, it seems the behaviour is different: If the properties are not present in the properties file I get the following exception: SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'annotationMapping' defined in class path resource [com/northgateis/pole/ws/applicationContext-ws.xml]: Could not resolve placeholder 'validateRequest' at org.springframework.beans.factory.config.PropertyPlaceholderConfigurer.processProperties(PropertyPlaceholderConfigurer.java:272) at org.springframework.beans.factory.config.PropertyResourceConfigurer.postProcessBeanFactory(PropertyResourceConfigurer.java:75) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:640) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:615) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:405) at org.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:272) I tried dabbling with Spring EL but the following doesn't seem to work: <bean class="com.northgateis.pole.ws.PolePayloadValidatingInterceptor"> <property name="validateRequest" value="${validateRequest?:true}" /> <property name="validateResponse" value="${validateResponse?:false}" /> </bean> The value after the Elvis operator is always used, even when the properties are defined in the proeprties file. Interesting that the syntax is accepted. Any suggestions?

  • Powershell - Splitting string into seperate components

    - by TheD
    I am writing a script which will basically do the following: Read from a text file some arguements: DriveLetter ThreeLetterCode ServerName VolumeLetter Integer Eg. W MSS SERVER01 C 1 These values happen to form a folder destination W:\MSS\, and a filename which works in the following naming convention: SERVERNAME_VOLUMELETTER_VOL-b00X-iYYY.spi - Where The X is the Integer above The value Y I need to work out later, as this happens to be the value of the incremental image (backups) and I need to work out the latest incremental. So at the moment -- Count lines in file, and loop for this many lines. $lines = Get-Content -Path PostBackupCheck-Textfile.txt | Measure-Object -Line for ($i=0; $i -le $lines.Lines; $i++) Within this loop I need to do a Get-Content to read off the line I am currently looking at i.e. line 0, line 1, line 2, as there will be multiple lines in the format I wrote at the beginning and split the line into an array, whereby each part of the file, as seen above naming convention, is in a[0], a[1], a[2]. etc The reason for this is because, I need to then sort the folder that contains these, find the latest file, by date, and take the _iXXX.spi part and place this into the array value a[X] so I then have a complete filename to mount. This value will replace iYYY.spi It's a little complex because I also have to make sure when I do a Get-ChildItem with -Include before I sort it all by date, I am only including the filename that matches the arguements fed to it from the text file : So, SERVER01_C_VOL-b001-iYYY.spi and not anything else. i.e. not SERVER01_D_VOL-b001-iYYY.spi Then take the iYYY value from the sort on the Get-ChildItem -Include and place that into the appropriate array item. I've literally no idea where to start, so any ideas are appreciated! Hopefully I've explained in enough detail. I have also placed the code on Pastebin: http://pastebin.com/vtFifTW6 Thanks!

  • Can you help with this assembly language code?

    - by Mugen
    Hi, I've been looking through a piece of code of a pc game that I'm trying to "improve". (ok so maybe I suck at the game but I still want to play it). Could you please look into the following code: fld dword ptr[ebp+00007B1C] fsub dword ptr[esp+64] fst dword ptr[ebp+00007B1C] call 004A2E48 This code is called every second for the level countdown timer. I need to stay on a particular level for a few minutes. If I can modify the above code so that the value pushed into the address [ebp+00007B1C] is 0 then the game level will always time out and it will save me playing those crazy "survival" minigames. I'll explain what I understand from this code. Dont worry, you dont have to go deep into this. In the first line we get the timer value. For example if 97 seconds are remaining then it is here that this value is loaded. In the second line a value (1 second) is subtracted from 97. In the third line 96 is again moved to memory. And finally we have the function call that will do other processing based on the time remaining. Now all I need to do is patch this piece of code somehow so that the value that is pushed is 0 (in the third step). Can you please help me out with this?

  • Searches (and general querying) with HBase and/or Cassandra (best practices?)

    - by alexeypro
    I have User model object with quite few fields (properties, if you wish) in it. Say "firstname", "lastname", "city" and "year-of-birth". Each user also gets "unique id". I want to be able to search by them. How do I do that properly? How to do that at all? My understanding (will work for pretty much any key-value storage -- first goes key, then value) u:123456789 = serialized_json_object ("u" as a simple prefix for user's keys, 123456789 is "unique id"). Now, thinking that I want to be able to search by firstname and lastname, I can save in: f:Steve = u:384734807,u:2398248764,u:23276263 f:Alex = u:12324355,u:121324334 so key is "f" - which is prefix for firstnames, and "Steve" is actual firstname. For "u:Steve" we save as value all user id's who are "Steve's". That makes every search very-very easy. Querying by few fields (properties) -- say by firstname (i.e. "Steve") and lastname (i.e. "l:Anything") is still easy - first get list of user ids from "f:Steve", then list from "l:Anything", find crossing user ids, an here you go. Problems (and there are quite a few): Saving, updating, deleting user is a pain. It has to be atomic and consistent operation. Also, if we have size of value limited to some value - then we are in (potential) trouble. And really not of an answer here. Only zipping the list of user ids? Not too cool, though. What id we want to add new field to search by. Eventually. Say by "city". We certainly can do the same way "c:Los Angeles" = ..., "c:Chicago" = ..., but if we didn't foresee all those "search choices" from the very beginning, then we will have to be able to create some night job or something to go by all existing User records and update those "c:CITY" for them... Quite a big job! Problems with locking. User "u:123" updates his name "Alex", and user "u:456" updates his name "Alex". They both have to update "f:Alex" with their id's. That means either we get into overwriting problem, or one update will wait for another (and imaging if there are many of them?!). What's the best way of doing that? Keeping in mind that I want to search by many fields? P.S. Please, the question is about HBase/Cassandra/NoSQL/Key-Value storages. Please please - no advices to use MySQL and "read about" SELECTs; and worry about scaling problems "later". There is a reason why I asked MY question exactly the way I did. :-)

  • What are the best workarounds for known problems with Hibernate's schema validation of floating poin

    - by Jason Novak
    I have several Java classes with double fields that I am persisting via Hibernate. For example, I have @Entity public class Node ... private double value; When Hibernate's org.hibernate.dialect.Oracle10gDialect creates the DDL for the Node table, it maps the value field to a "double precision" type. create table MDB.Node (... value double precision not null, ... It would appear that in Oracle, "double precision" is an alias for "float". So, when I try to verify the database schema using the org.hibernate.cfg.AnnotationConfiguration.validateSchema() method, Oracle appears to describe the value column as a "float". This causes Hibernate to throw the following Exception org.hibernate.HibernateException: Wrong column type in DBO.ACL_RULE for column value. Found: float, expected: double precision A very similar problem is listed in Hibernate's JIRA database as HHH-1961 (http://opensource.atlassian.com/projects/hibernate/browse/HHH-1961). I'd like to avoid doing anything that will break MySql, Postgres, and Sql Server support so extending the Oracle10gDialect appears to be the most promising of the workarounds mentioned in HHH-1961. But extending a Dialect is something I've never done before and I'm afraid there may be some nasty gotchas. What is the best workaround for this problem that won't break our compatibility with MySql, Postgres, and Sql Server? Thanks for taking the time to look at this!

  • Validating a single radio button is not working in available javascript validation script

    - by OM The Eternity

  • Managing multiple AJAX calls to PHP scripts

    - by relativelycoded
    I have a set of 5 HTML dropdowns that act as filters for narrowing results returned from a mySQL database. The three pertinent filters are for "Province", "Region", and "City" selection, respectively. I have three functions: findSchools(), which runs when any of the filters (marked with CSS class .filter) are changed, and fetches the results via AJAX from a PHP script. Once that is done, two other functions are called... changeRegionOptions(), which, upon changing the "Province" filter, and updates the available options using the same method as the first function, but posting to a different script. changeCityOptions(), which runs if the "Region" filter was changed, and updates options, again using the same method. The problem is that since I want these AJAX functions to run simultaneously, and they by nature run asynchronously, I've tried using $.when to control the execution of the functions, but it doesn't fix the problem. The functions run, but the Region and City filters return blank (no options); the FireBug report shows absolutely no output, even though the POST request went through. The posted parameter for filter_province gets sent normally, but the one for region gets cut off at the end -- it sends as filter_region=, with no value passed. So I'm presuming my logic is wrong somewhere. The code is below: // When any of the filters are changed, let's query the database... $("select.filter").change(function() { findSchools(); }); // First, we see if there are any results... function findSchools() { var sch_province = document.filterform.filter_province.value; var sch_region = document.filterform.filter_region.value; var sch_city = document.filterform.filter_city.value; var sch_cat = document.filterform.filter_category.value; var sch_type = document.filterform.filter_type.value; $.post("fetch_results.php", { filter_province : sch_province, filter_region : sch_region, filter_city : sch_city, filter_category : sch_cat, filter_type : sch_type }, function(data) { $("#results").html(""); $("#results").hide(); $("#results").html(data); $("#results").fadeIn(600); } ); // Once the results are fetched, we want to see if the filter they changed was the one for Province, and if so, update the Region and City options to match that selection... $("#filter_province").change(function() { $.when(findSchools()) .done(changeRegionOptions()); $.when(changeRegionOptions()) .done(changeCityOptions()); }); }; This is just one of the ways I've tried to solve it; I've tried using an IF statement, and tried calling the functions directly inside the general select.filter.change() function (after findSchools(); ), but they all return the same result. Any help with this would be great!

  • WPF Trigger / Style overrides another

    - by ozczecho
    I have a listview defined as such <ListView Width="auto" SelectionMode="Single" ItemContainerStyle="{StaticResource baseListViewStyle}" .... Then in "baseListViewStyle" I have defined some base styles to apply to my list views, including a Style trigger: <Style x:Key="baseListViewStyle" TargetType="ListViewItem"> <Setter Property="Height" Value="20" /> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Foreground" Value="Red" /> </Trigger> </Style.Triggers> </Style> The trigger here highlights the row when mouse is over it. Nice. I also have a Data Trigger on the listviewitem: <Style.Triggers> <DataTrigger Binding="{Binding IsTestTrue}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource SomeFunkyAnimation}" /> </DataTrigger.EnterActions> </DataTrigger> If test is true then a nice little fade animation is played out. This all works except when I move my mouse over the row where "test is true" the animation stops and the mouse over style is displayed. Any ideas how I can override that style in my DataTrigger? TIA
