  • jQuery: Hide/Display tabs (and its corresponding content) with check boxes

    - by Ricardo
    Hello, Well, this must be very simple to do for most of you, but I have no idea how to accomplish this. I have a set of tabs and on top of the tabs is a set of checkboxes ; each checkbox 'corresponds' to a tab. What I need is to be able to activate/deactivate each checkbox and have its corresponding tab (and the tab's content) hide/display. Here's my HTML: <div class="show-results-from"> <ul> <li>See results from:</li> <li> <label> <input type="checkbox" name="a" id="a"> Products &amp; Services <span>(16)</span></label> </li> <li> <label> <input type="checkbox" name="b" id="b"> Publications <span>(9)</span></label> </li> <li> <label> <input type="checkbox" name="c" id="c"> Other <span>(150)</span></label> </li> </ul> </div> <ul class="tabs"> <li><span rel="tabs1" class="defaulttab">Products &amp; Services</span></li> <li><span rel="tabs2">Publications</span></li> <li><span rel="tabs3">Other</span></li> </ul> <div class="tab-content" id="tabs1">content</div> <div class="tab-content" id="tabs2">content</div> <div class="tab-content" id="tabs3">content</div> Any help with this is greatly appreciated.

  • C# Constructor Problem When Using Generics

    - by Jimbo
    Please see an example of my code below: public class ScrollableCheckboxList { public List<ScrollableCheckboxItem> listitems; public void ScrollableCheckboxList<TModel>(IEnumerable<TModel> items, string valueField, string textField, string titleField) where TModel : class { listitems = new List<ScrollableCheckboxItem>(); foreach (TModel item in items) { Type t = typeof(TModel); PropertyInfo[] props = new [] { t.GetProperty(textField), t.GetProperty(valueField), t.GetProperty(titleField) }; listitems.Add(new ScrollableCheckboxItem { text = props[0].GetValue(item, null).ToString(), value = props[1].GetValue(item, null).ToString(), title = props[2].GetValue(item, null).ToString() }); } } } The code produces the following error: 'ScrollableCheckboxList': member names cannot be the same as their enclosing type This clearly means that there is a method in the class that has the same name as the class, but usually insinuates that the method is trying to return something (which is not allowed) In my case, all I have done is declare a constructor - why would this be a problem?

  • (Java) Get value of string loaded into dynamic-type object?

    - by Michael
    I'm very new to Java (~10 days), so my code is probably pretty bad, but here's what I've got: ArgsDataHolder argsData = new ArgsDataHolder(); // a class that holds two // ArrayList's where each element // representing key/value args Class thisArgClass; String thisArgString; Object thisArg; for(int i=2; i< argsString.length; i++) { thisToken = argsString[i]; thisArgClassString = getClassStringFromToken(thisToken).toLowerCase(); System.out.println("thisArgClassString: " + thisArgClassString); thisArgClass = getClassFromClassString(thisArgClassString); // find closing tag; concatenate middle Integer j = new Integer(i+1); thisArgString = getArgValue(argsString, j, "</" + thisArgClassString + ">"); thisArg = thisArgClass.newInstance(); thisArg = thisArgClass.valueOf(thisArgString); argsData.append(thisArg, thisArgClass); } The user basically has to input a set of key/value arguments into the command prompt in this format: <class>value</class>, e.g. <int>62</int>. Using this example, thisArgClass would be equal to Integer.class, thisArgString would be a string that read "62", and thisArg would be an instance of Integer that is equal to 62. I tried thisArg.valueOf(thisArgString), but I guess valueOf(<String>) is only a method of certain subclasses of Object. For whatever reason, I can't seem to be able to cast thisArg to thisArgClass (like so: thisArg = (thisArgClass)thisArgClass.newInstance();, at which point valueOf(<String>) should become accessible. There's got to be a nice, clean way of doing this, but it is beyond my abilities at this point. How can I get the value of the string loaded into a dynamically-typed object (Integer, Long, Float, Double, String, Character, Boolean, etc.)? Or am I just overthinking this, and Java will do the conversion for me? :confused:

  • CSS - Why am I not able to set height and width of <a href> elements?

    - by Kenny Bones
    Hi, I'm trying to create css buttons by using the following html markup: <a href="access.php" class="css_button_red">Forgot password</a> But it ends up being not bigger than the text in the middle. Even though I've set the class's height and width. You can preview the problem here btw, www.matkalenderen.no Notice the first button, that's a form button and it's using it's own class. At first I tried to use the same class on the css button as well and the same problem appeared, so I tried to separate them into their own classes. In case there was some kind of crash. But it didn't matter anyway. What am I missing here?

  • parallel.foreach with custom collection

    - by SchwartzE
    I am extending the System.Net.Mail.MailAddress class to include an ID field, so I created a new custom MailAddress class that inherited from the existing class and a new custom MailAddressCollection class. I then overrode the existing System.Net.Mail.MailMessage.To to use my new collection. I would like to process the recipients in parallel, but I can't get the syntax right. This is the syntax I am using. Parallel.ForEach(EmailMessage.To, (MailAddress address) => { emailService.InsertRecipient(emailId, address.DisplayName, address.Address, " "); }); I get the following errors: The best overloaded method match for 'System.Threading.Tasks.Parallel.ForEach(System.Collections.Generic.IEnumerable, System.Action)' has some invalid arguments Argument 1: cannot convert from 'EmailService.MailAddressCollection' to 'System.Collections.Generic.IEnumerable' What syntax do I need to use custom collections?

  • Javascript form validation only works in firefox

    - by Logic Artist
    Hello, I am relatively new to Javascript so I'm hoping this is a simple mistake. I building a generic form validation function that is called on the form's onSubmit. The function loops through all the form's child elements, looks for certain classes, and analyzes the contents of the appropriate fields. If it finds something missing or erroneous, it displays the appropriate error message div and returns false, thus preventing the form from being submitted to the php page. It works well in firefox 3.6.3, but in every other browser I've tested (Safari 4.0.4, Chrome 4.1, IE8) it seems to ignore the onSubmit and jump straight to the php processing page. HTML CODE: <form name='myForm' id='myForm' action='process_form.php' method='post' onSubmit="return validateRequired('myForm')"> <fieldset class="required radioset"> <label for='selection1'> <input type='radio' name='selection' id='selection1' value='1'/> Option 1 </label> <label for='selection2'> <input type='radio' name='selection' id='selection2' value='2'/> Option 2 </label> <label for='selection3'> <input type='radio' name='selection' id='selection3' value='3'/> Option 3 </label> <label for='selection4'> <input type='radio' name='selection' id='selection4' value='4'/> Option 4 </label> <div class='errorBox' style='visibility:hidden'> Please make a selection </div> </fieldset> <fieldset class="required checkset"> <label> Choice 1 <input type='checkbox' name='choices' id='choice1' value='1'/> </label> <label> Choice 2 <input type='checkbox' name='choices' id='choice2' value='2'/> </label> <label> Choice 3 <input type='checkbox' name='choices' id='choice3' value='3'/> </label> <label> Choice 4 <input type='checkbox' name='choices' id='choice4' value='4'/> </label> <div class='errorBox' style='visibility:hidden'> Please choose at least one </div> </fieldset> <fieldset class="required textfield" > <label for='textinput1'> Required Text: <input type='text' name='textinput1' id='textinput1' size='40'/> </label> <div class='errorBox' style='visibility:hidden'> Please enter some text </div> </fieldset> <fieldset class="required email textfield"> <label for='email'> Required Email: <input type='text' name='email' id='email' size='40'/> </label> <div class='errorBox' style='visibility:hidden'> The email address you have entered is invalid </div> </fieldset> <div> <input type='submit' value='submit'> <input type='reset' value='reset'> </div> </form> JAVASCRIPT CODE: function validateRequired(id){ var form = document.getElementById(id); var errors = 0; var returnVal = true; for(i = 0; i < form.elements.length; i++){ var elem = form.elements[i]; if(hasClass(elem,"required")){ /*RADIO BUTTON or CHECK BOX SET*/ if(hasClass(elem,"radioset") || hasClass(elem,"checkset")){ var inputs = elem.getElementsByTagName("input"); var check = false; for(j = 0; j < inputs.length; j++){ if(inputs[j].checked){ check = true; } } if(check == false){ errors += 1; showError(elem); } else { hideError(elem); } } /*TEXT FIELD*/ else if(hasClass(elem,"textfield")){ var input = elem.getElementsByTagName("input"); if(input[0].value == ""){ errors += 1; showError(elem); } else { hideError(elem); /*EMAIL ADDRESS*/ if(hasClass(elem,"email")){ if(isValidEmail(input[0].value) == false){ errors += 1; showError(elem); } else { hideError(elem); } } } } } } if(errors > 0){ returnVal = false; } else { returnVal = true; } return returnVal;} I know this is a lot of code to look at, but any help would be appreciated. Since it works fine in one browser, Im not sure how to start debugging. Thanks Andrew

  • Why does the check for an interface fail?

    - by chobo
    I have a class that implements an interface. In another area of the code I check if that class instance contains that interface, but it doesn't work. The check to see if the class contains the interface always fails (false) when it should be true. Below is a simple representation of what I am trying to accomplish. Example public interface IModel { bool validate(); } public class SomeModel : IModel { public SomeModel { } public bool Validate() { return true; } } // Dummy method public void Run() { SomeModel model = new SomeModel(); if (model is IModel) { string message = "It worked"; } else { string message = "It failed"; } }

  • seeking help with Chrome & Safari not rendering my table stretched to fit its contents...help?

    - by oompa_l
    I have an element on this web page I'm developing where I need my text to conform to the width of an image above it - whose width will always be different - think of captions. I have found numerous references to using a 1px table to force this width sizing behaviour. I am having problems, though with Safari and Chrome "seeing" this instruction - the text ends up as a marginally sized text box sitting behind the image. The problem, as I see it, has to do with the text and images sitting in div's nested within the table. I need the images to sit in a div because of some jquery script I'm using called cycle, which turns a group of images into a slideshow. The problem may have something to do with the script as well. In any case, I have tried a seeming infinite number of combination of floating left and clearing left on all all the divs, changing their positions and widths...nothing works. Anyone have any clues about how to broach this one? EDIT 1: ok, should I be editing my post or responding with answers? here's the url to see the problem I am having - http://friedmanstudios.ca/webdev/test8.html and the code: <div id="content" class="boxes"> <table> <tr> <td > <div id="imageFrame"> <a href="#" class="img" title="_MG_9786_fmt.jpeg"> <img src="images/_MG_9786_fmt.jpeg"/> </a> <a href="#" class="img" title="IMG_5169_fmt.jpeg"> <img src="indesign export/GFA-TEARSHEETS-100526-01-web-images/IMG_5169_fmt.jpeg"/> </a> <a href="#" class="img" title="IMG_5175_fmt.jpeg"> <img src="indesign export/GFA-TEARSHEETS-100526-01-web-images/IMG_5175_fmt.jpeg"/> </a> <a href="#" class="img" title="aerial_fmt.jpeg" width=""> <img src="indesign export/GFA-TEARSHEETS-100526-01-web-images/aerial_fmt.jpeg"/> </a> </div> <div id="cycleCtrl"> <div id="prev" class="pager"><a href="#">< Prev</a> </div> <div id="next" class="pager"><a href="#">Next ></a></div> <div id="pagerNav" class="pager"></div> </div> <div id="descController"> <img src="images/arrow.gif" name="arrow" width="5" height="10" id="arrow" /> <span id="projectName">Toronto Centre for the Arts </span> <br /> <div id="desc"> In the past eight years... </div> </div></td> <td width="90%"><!--push col 1 back--></td> </tr> </table> and the styles: #content { position: absolute; top: 250px; left: 275px; float: left; clear: both; } content table { float: left; width: 1px; } imageFrame { position: relative; float: left; clear: left; width: inherit; } desc { position: relative; clear: left; float: left; } descController { position:relative; padding-top:5px; padding-bottom:10px; clear: left; float: left; } descController div { height:0; overflow:hidden; -webkit-transition:all .5s ease; -moz-transition:all .5s ease; -o-transition:all .5s ease; transition:all .5s ease; padding-top:10px; margin-top: 10px; word-spacing: 0em; line-height: 16px; font-size: 12px; position: relative; float: left; clear: left; }

  • Copy values from one object to another.

    - by BrokeMyLegBiking
    Anyone have a suggestion for a good utility class that maps values from one object to another? I want a utility class that uses reflection and takes two objects and copies values from the 1st object to the second if there is a public property with the same name. I have two entities that are generated from a web service proxy, so I can't change the parent class or impliment an interface or anything like that. But I know that the two objects have the same public properties.

  • Why does Java think my object is a variable?

    - by user2896898
    Ok so I'm trying to make a simple pong game. I have a paddle that follows the mouse and a ball that bounces around. I wrote a method collidesWith(Sprite s) inside of my Sprite class that checks if the ball collides with the paddle (this works and isn't the problem). I have two objects extending my sprite class, a ball and a paddle object. So inside of my ball class I'm trying to check if it collides with the paddle. So I've tried if(this.collidesWith(paddle) == true){ System.out.println("They touched"); } I've also tried ball.collidesWith(paddle) and other combinations but it always says the same thing about the paddle (and the ball when I use ball.collidesWith) "Cannot find symbol. Symbol: variable paddle(or ball). Location: class Ball" So if I'm reading this right, it thinks that the paddle (and ball) are variables and it's complaining because it can't find them. How can I make it understand I am passing in objects, not variables? For extra information, an earlier assignment had me make two boxes and for them to change colors when they were colliding. In that assignment I used very similar code to above with if(boxOne.collidesWith(boxTwo) == true){ System.out.println("yes"); } And in this code it worked just fine. The program knew that boxOne and boxTwo were child classes of my Sprite class. Anyone know why they wouldn't work the same?

  • Has inheritance become bad?

    - by mafutrct
    Personally, I think inheritance is a great tool, that, when applied reasonably, can greatly simplify code. However, I seems to me that many modern tools dislike inheritance. Let's take a simple example: Serialize a class to XML. As soon as inheritance is involved, this can easily turn into a mess. Especially if you're trying to serialize a derived class using the base class serializer. Sure, we can work around that. Something like a KnownType attribute and stuff. Besides being an itch in your code that you have to remember to update every time you add a derived class, that fails, too, if you receive a class from outside your scope that was not known at compile time. (Okay, in some cases you can still work around that, for instance using the NetDataContract serializer in .NET. Surely a certain advancement.) In any case, the basic principle still exists: Serialization and inheritance don't mix well. Considering the huge list of programming strategies that became possible and even common in the past decade, I feel tempted to say that inheritance should be avoided in areas that relate to serialization (in particular remoting and databases). Does that make sense? Or am messing things up? How do you handle inheritance and serialization?
