  • adding a class when link is clicked from Wordpress loop

    - by Carey Estes
    I am trying to isolate and add a class to a clicked anchor tag. The tags are getting pulled from a Wordpress loop. I can write JQuery to remove the "static" class, but it is removing the class from all tags in the div rather than just the one clicked and not adding the "active" class. Here is the WP loop <div class="more"> <a class="static" href="<?php bloginfo('template_url'); ?>/work/">ALL</a> <?php foreach ($tax_terms as $tax_term) { echo '<a class="static" href="' . esc_attr(get_term_link($tax_term, $taxonomy)) . '" title="' . sprintf( __( "View all posts in %s" ), $tax_term->name ) . '" ' . '>' . $tax_term->name.'</a>'; } ?> </div> Generates this html: <div class="more"> <a class="static" href="#">ALL</a> <a class="static" href="#">Things</a> <a class="static" href="#"> More Things</a> <a class="static" href="#">Objects</a> <a class="static" href="#">Goals</a> <a class="static" href="#">Books</a> <a class="static" href="#">Drawings</a> <a class="static" href="#">Thoughts</a> </div> JQuery: $("div.more a").on("click", function () { $("a.static").removeClass("static"); $(this).addClass("active"); }); I have reviwed the other similar questions here and here, but neither solution is working for me. Can this be done with JQuery or should I put a click event in the html inline anchor? It looks like it is working just for a second until the page reloads.

  • Where can I find a comprehensive reference for Zen Cart variables and overrides?

    - by Angelina
    Hi everyone, I'm working with Zen Cart for a client and I'm having a bit of trouble finding a practical, concise resource that gives reference to the most common template variables and overrides. This project is fairly superficial so that is all I need - but bonus points if you find something that goes a little bit deeper. Please note that I am looking for something that is 'at a glance', like a reference card. I have already looked at several books on Zen Cart, but most of them are designed for the end user or a sysadmin at most and leave much to be desired.

  • How does one inject variables into page templates from a custom Drupal module?

    - by Michael T. Smith
    We've created a custom module for organizing and publishing our newsletter content. The issue I'm running into now -- and I'm new to theming and Drupal module development, so it could just be a knowledge issue as opposed to a Drupal issue -- is how to get each newsletter themed. At this point the URL structure of our newsletter will be: /newsletters/{newsletter-name}/{edition-name}/{issue-date} which means that we can create template files in our theme using filenames like page-newsletters-{newsletter-name}-{edition-name}.tpl.php, which is great. The one issue I'm running into is that all of the content comes through in the $content variable of the theme. I'd like to have it come through as different variables (so that I can, inside the theme, place certain content in certain areas.) Is there a proper way for doing this?

  • Optimal method to create a large string containing several variables?

    - by Runcible
    I want to create a string that contains many variables: std::string name1 = "Frank"; std::string name2 = "Joe"; std::string name3 = "Nancy"; std::string name4 = "Sherlock"; std::string sentence; sentence = name1 + " and " + name2 + " sat down with " + name3; sentence += " to play cards, while " + name4 + " played the violin."; This should produce a sentence that reads Frank and Joe sat down with Nancy to play cards, while Sherlock played the violin. My question is: What is the optimal way to accomplish this? I am concerned that constantly using the + operator is ineffecient. Is there a better way?

  • Should I call release on these cocoa objective-c variables?

    - by Andrew Arrow
    In the code below I'm making a new NSString with alloc and initializing it with the contents of some file. Because I'm calling alloc I know it's my responsibility to call release on the string when I'm done. But what about the variables "lines" and "line"? Since the method "componentsSeparatedByString" does not start with the word "new" or "create" can I assume "lines" will be autoreleased? Same question for "line" since "objectAtIndex" also does not start with "new" or "create". NSString* buffer = [[NSString alloc] initWithData:[fileManager contentsAtPath:@"/foo"] encoding:NSUTF8StringEncoding]; NSArray* lines = [buffer componentsSeparatedByString:@"\n"]; NSString* line = [lines objectAtIndex:5]; // do something with line [buffer release]; So is the code above okay? Or should I be calling "release" on lines and line too? Thanks.

  • How do I assign selected WPF datagrid row columns to variables. (VB.NET)

    - by Peter
    Hi, I have a datagrid with customer data such as ID, name, email, phone etc. When I select a row (with a button or selectionchanged) I want to store that row's columns in variables like dim email as string dim name as string email = dgCustomers.theselectedrow.theselectedcell name = dgCustomers.theselectedrow.theselectedcell If I have a datatable with only one row I know I can get column data with: dim email as string = CustomerDataTableInstance.rows(0).Item("Email") I don't know how to get the selected row number though when I have several rows and the user clicks one/uses the keyboard. The datagrid is bound to a datatable, not a class with object collections. Any help is appreciated!

  • Can I get the method local variables through a stack trace in C#?

    - by smwikipedia
    I want to get a detailed log about my stack trace. I can get a StackFrame and then the method and then get all the parameters of that method. Just as the following code: StackTrace st = new StackTrace(); StackFrame[] sfs = st.GetFrames(); foreach (StackFrame sf in sfs) { MethodBase method = sf.GetMethod(); ParameterInfo[] pis = method.GetParameters(); foreach (ParameterInfo pi in pis) { .... } Console.WriteLine(method.Name); } But how could I get the local variables infomation within a method? Could someone shed some light on me? Many thanks.

  • How do I pass custom variables to javascript events?

    - by RoboShop
    I have a user control with a javascript function which references some controls within the user control. This user control works perfectly when there is only one instance of it, but I'm now building a page where I have two instances of the user control. In IE7, it works fine, but in FireFox, it is getting confused that there is two functions of the exact same name and signature. So on UserControl1, it'll be running the function in UserControl2 and modifying that content. I'm thinking my best solution would be to pass the clientID of the components I need TO the function instead of just directly referencing it in the function. How would I do that? The signature of the javascript function is like this function nodeClicking(sender, args) and I'm calling it in an event like this <telerik:RadTreeView runat="server" ID="OrgUnitTreeView" OnInit="TreeViewLoad" OnClientNodeClicking="**nodeClicking**" EnableViewState="true" DataTextField = "OrganisationUnitName" DataValueField = "OrganisationUnitCode" DataFieldParentID = "ParentOrganisationUnitCode" DataFieldID = "OrganisationUnitCode"> How do I add extra variables to the function signature.

  • How to use a regular expression and assign the result to variables in Android?

    - by ChengYing
    I have a string named s_Result which will be parsed from the Internet. The format may be "Distance: 2.8km (about 9 mins)", and there are 4 variables which are f_Distance, m_DistanceUnit, f_timeEst, m_timeEstUnit. My question is how to parse s_Result and assign 2.8, km, 9, mins into f_Distance, m_distanceUnit, f_timeEst and m_timeEstUnit respectively using regular expression? I tried using "\d+(\.\d+)?" in RegEx Tester and the result showed 2 matches found, but if I use "\\d+(\\.\\d+)?" in Android code, it showed no matches! Any suggestions what might be going wrong?

  • What is the impact/limitation of oracle select with large number of bind variables?

    - by Igal Serban
    We had our oracle server chocking during processing a select statement with close to 3500(!!) bind variables. This select is, obviously, build dynamically by code that we can't change. During the execution of this select the db server went to 100% cpu usage and our system almost halted. We know how to reproduce this problem. So we can prevent this specific condition. But I am wondering if there is a way to protect the db ( by configuration) from this type of problems.

  • How can I pass query string variables with NavigationService.Navigate?

    - by Mike Hildner
    Greetings, Searched for this, but no luck. I'm attempting to pass query string variables (and then retrieve them) in my Silverlight 4 app. First I tried this this.NavigationService.Navigate(new Uri("/LoanProductionRegion?Elvis=Alive&ImHungry=true", UriKind.Relative)); But HtmlPage.Document.QueryString doesn't pick them up because they come after the anchor (the full url looks like http://localhost:1076/Dashboard.SLTestPage.aspx#/LoanProductionRegion?Elvis=Alive&ImHungry=true). I tried to put the vars in front, such as this.NavigationService.Navigate(new Uri("?Elvis=Alive&ImHungry=true/LoanProductionRegion", UriKind.Relative)); this.NavigationService.Navigate(new Uri("/?Elvis=Alive&ImHungry=true/LoanProductionRegion", UriKind.Relative)); But both result in a "Page not found" error. Anyone know how to achieve what I'm after?

  • jQuery is it possible to concatenate two selector variables?

    - by Kris Hollenbeck
    Lets say I have two variables defining separate selectors, for example... var parent = $('.parent'); var child = $('.child'); And I want to create a something like the following... $(parent + child).click(); Which should be equivalent to doing this (if it was correct syntax)... $('.parent .child').click(); This may not be best practice, however I am curious if it is possible. Thanks for your help in advance.

  • Is it possible to preg replace unique variables into a string?

    - by Scarface
    What I want to do is use preg replace to replace matches within a string with a varying replacement, and I was wondering if anyone knew if that is possible in php or at least achievable by some means. For example, a string has two matches, then those matches will be replaced with two different variables. What I want are replacements to each be a unique id and I cannot figure out how this could possibly work or if php could even do this. For example if the match is 'a' and there is a sentence, 'put a smile on a person' then one 'a' will be unique id 98aksd00 and the other will be 09alkj08. I am retrieving my comments from a database so the preg replace is happening within while ($row=mysql_fetch_assoc($query)){ //preg replace If anyone could provide any insight into this, I would really appreciate it

  • How should I declare default values for instance variables in Python?

    - by int3
    Should I give my class members default values like this: class Foo: num = 1 or like this? class Foo: def __init__(self): self.num = 1 In this question I discovered that in both cases, bar = Foo() bar.num += 1 is a well-defined operation. I understand that the first method will give me a class variable while the second one will not. However, if I do not require a class variable, but only need to set a default value for my instance variables, are both methods equally good? Or one of them more 'pythonic' than the other? One thing I've noticed is that in the Django tutorial, they use the second method to declare Models. Personally I think the second method is more elegant, but I'd like to know what the 'standard' way is.

  • How can I manage command line arguements/variables for a script written in Perl?

    - by Structure
    I am trying to manage numerous arguments that are specified by a user when they execute a command. So far, I have been trying to limit my script design to manage arguments as flags that I can easily manage with Getopt::Long as follows: GetOptions ("a" => \$a, "b" => \$b); In this way I can check to see if a or b were specified and then execute the respective code/functions. However, I now have a case where the user can specify two arguments variables as follows: command -a black -b white This is fine, but I cannot come up with a good way to determine whether -a or -b is specified first. Therefore I do not know whether the argument variable is assigned to $ARGV[0] or $ARGV[1] after I have executed GetOptions ("a" => \$a, "b" => \$b);. How can I tell which variable is associated with -a and which is associated with -b in the example above?

  • Is a function kind of like a static method?

    - by lkm
    I'm a java programmer and am trying to understand the difference between a method (java methods) and a function (such as in c++). I used to think that they are the same, just different naming conventions for different programming languages. But now that I know they are not, I am having trouble understanding the difference. I know that a method relates to an instance of a class and has access to class data (member variables), while a function does not (?). So is a function kind of like a static method? See here for explanations I read which led me to think this.

  • Definition of variables/fields type within a constructor, how is it done?

    - by elementz
    I just had a look at Suns Java tutorial, and found something that totally confused me: Given the following example: public Bicycle(int startCadence, int startSpeed, int startGear) { gear = startGear; cadence = startCadence; speed = startSpeed; } Why is it, that the types of the variables (fields?) gear, cadence and speed do not need to be defined? I would have written it as follows: public Bicycle(int startCadence, int startSpeed, int startGear) { int gear = startGear; int cadence = startCadence; int speed = startSpeed; } What would be the actual differnce?

  • Explicitly typing variables causes compiler to think an instance of a builtin type doesn't have a pr

    - by wallacoloo
    I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this: var test_inst:Number = 2.953; trace(test_inst); trace(test_inst.constructor); I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error: var test_inst = 2.953; trace(test_inst); trace(test_inst.constructor); it produces the expected output: 2.953 [class Number] So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?

  • How to paste text and variables into a logical expression in R?

    - by Jasper
    I want to paste variables in the logical expression that I am using to subset data, but the subset function does not see them as column names when pasted (either with ot without quotes). I have a dataframe with columns named col1, col2 etc. I want to subset for the rows in which colx < 0.05 This DOES work: subsetdata<-subset(dataframe, col1<0.05) subsetdata<-subset(dataframe, col2<0.05) This does NOT work: for (k in 1:2){ subsetdata<-subset(dataframe, paste("col",k,sep="")<0.05) } for (k in 1:2){ subsetdata<-subset(dataframe, noquote(paste("col",k,sep=""))<0.05) } I can't find the answer; any suggestions?

  • How many variables is to many when storing in _SESSION?

    - by steve
    Hi - I'm looking for an idea of best practices here. I have a web based application that has a number of hooks into other systems. Let's say 5, and each of these 5 systems has a number of flags to determine different settings the user has selected in said systems, lets say 5 settings per system (so 5*5). I am storing the status of these settings in the user sesion variables and was wondering is that a sufficient way of doing it? I'm learning php as I go along so not sure about any pitfalls that this could run me into!

  • Why are Objective-C instance variables declared in an interface?

    - by Chase
    I'm just getting into Objective-C (Java is my primary OO language). Defining an object's instance variables in the interface instead of the class seems strange. I'm used to an interface being a public API definition with nothing besides method signatures (not counting constants here). Is there some reason that state is defined in an interface (even if it is private) and behaviour is defined in a class. It just seems odd that since objects are state+behavior that the definition would be split into two separate places. Is it a design benefit is some way? A pain in the rear issue that you are just forced to deal with in Objective-C? A non-issue, just different? Any background on why it's done this way? Or can you put object state in a class and I just haven't hit that part in my book yet?
