  • How to use the Value of a Selected Value from a DropDownList populated with AJAX/PHP

    - by mouthpiec
    Hi, I have form with two dropdownlists (lets say A and B). When I select a value from A, B is being populated accordingly using AJAX In the same page I have a button, that when pressed, posts the values of the selected items of the dropdownlists to another PHP page. The problem I am having is that the selected value of B is returned as Blank/Empty. Is there a way to store the selected value of a dropdownlist populated using AJAX? Code below: (Main FORM) <form name="NewBar" method="post" onsubmit="return validateFormOnSubmit(this)" action="AssignContactDetailToBar_f.php"> <tr> <td width="150"><b>Bar:</b></td> <td> <select name = "bar" onChange="getContact('AssignContactDetailToBar_f_getContacts.php?bar='+this.value)" size = 1 style = "width:190px"> <option value = "">---Select---</option> <?php while ($data = mysql_fetch_array($r_getBarsDetails)) { echo "<option value=\"".$data['bar_id']."\">".$data['bar_name']." (".$data['town_name'].")</option>"; } ?> </td> </tr> <tr> <td width="150"><b>Contact Person:</b></td> <td> <div id="persondiv"><select name = "person" size = 1 style = "width:190px"> <option value = "">--Select Bar--</option> </td> </tr> <tr> <td> <input name="security" type="text" size="15"> </td> <td> <input type="submit" name="Submit" value="Submit"> </td> </tr> </form> FORM to populate the 2nd Dropdownlist <select name="person" size = 1 style = "width:190px"> <option value = "">--Select Person--</option> <?php while($data=mysql_fetch_array($result)) { echo "<option value=\"".$data['person_id']."\">".$data['person_name']."

  • jQuery UI Multiple Dialogue's

  • Avoiding dispose of underlying stream

    - by danbystrom
    I'm attempting to mock some file operations. In the "real" object I have: StreamWriter createFile( string name ) { return new StreamWriter( Path.Combine( _outFolder, name ), false, Encoding.UTF8 ) ); } In the mock object I'd like to have: StreamWriter createFile( string name ) { var ms = new MemoryStream(); _files.Add( Path.Combine( _outFolder, name ), ms ); return new StreamWriter( ms, Encoding.UTF8 ) ); } where _files is a dictionary to store created files for later inspection. However, when the consumer closes the StreamWriter, it also disposes the MeamoryStream... :-( Any thoughts on how to pursue this?

  • Why is there a constructor method if you can assign the values to variables?

    - by Joel
    I'm just learning PHP, and I'm confused about what the purpose of the __construct() method? If I can do this: class Bear { // define properties public $name = 'Bill'; public $weight = 200; // define methods public function eat($units) { echo $this->name." is eating ".$units." units of food... <br />"; $this->weight += $units; } } Then why do it with a constructor instead? : class Bear { // define properties public $name; public $weight; public function __construct(){ $this->name = 'Bill'; $this->weight = 200; } // define methods public function eat($units) { echo $this->name." is eating ".$units." units of food... <br />"; $this->weight += $units; } }

  • Bizarre problem with WPF XAML file.

    - by paxdiablo
    I've just started a very simple WPF application which consists of a main large image and four smaller images. In order to assist with the layout, I created some JPEGs in MsPaint containing the images -2, -1, 0, +1 and +2 and just copied them into the top level of the project directory. The XAML segment contains, for the five images: <Image Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="4" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicture" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/zero.jpg" <Image Grid.Column="1" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus2.jpg" <Image Grid.Column="2" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus1.jpg" <Image Grid.Column="3" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus1.jpg" <Image Grid.Column="4" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus2.jpg" When I try to set the source property for the plus2 image, it complains with a dialog box stating: Property value is not valid. Details | V The file plus2.jpg is not part of the project or its 'Build Action' property is not set to 'Resource'. Yet if I rename the file to plus3.jpg or plus2x.jpg, I don't have that problem. Why is it complaining about plus2.jpg specifically?

  • How to serialize as an array of objects from multiple fields in jQuery?

    - by teebot.be
    Hi, I'm using jQuery to dynamically add new divs containing a few fields. I'm adding new tunes in this example of output: <div id="uploadedTunes"> <div class="tune"> Title:<input type="text" name="Title"> Length:<input type="text" name="Length"> </div> <div class="tune"> Title:<input type="text" name="Title"> Length:<input type="text" name="Length"> </div> </div> Is there a way to serialize only the fields in the div uploadedTunes (and not the whole form) ? And how do I serialize this so I have an array like this: uploadedTunes{ tune { Title="highway to hell", Length="03:01" } } Thank you for your help or clues!

  • Java appending XML data

    - by Travis
    I've already read through a few of the answers on this site but none of them worked for me. I have an XML file like this: <root> <character> <name>Volstvok</name> <charID>(omitted)</charID> <userID>(omitted)</userID> <apiKey>(omitted)</apiKey> </character> </root> I need to add another <character> somehow. I'm trying this but it does not work: public void addCharacter(String name, int id, int userID, String apiKey){ Element newCharacter = doc.createElement("character"); Element newName = doc.createElement("name"); newName.setTextContent(name); Element newID = doc.createElement("charID"); newID.setTextContent(Integer.toString(id)); Element newUserID = doc.createElement("userID"); newUserID.setTextContent(Integer.toString(userID)); Element newApiKey = doc.createElement("apiKey"); newApiKey.setTextContent(apiKey); //Setup and write newCharacter.appendChild(newName); newCharacter.appendChild(newID); newCharacter.appendChild(newUserID); newCharacter.appendChild(newApiKey); doc.getDocumentElement().appendChild(newCharacter); }

  • Use of (non) qualified names

    - by AProgrammer
    If I want to use the name baz defined in package foo|bar|quz, I've several choices: provide fbq as a short name for foo|bar|quz and use fbq|baz use foo|bar|quz|baz import baz from foo|bar|quz|baz and then use baz (or an alias given in the import process) import all public symbols from foo|bar|quz|baz and then use baz For the languages I know, my perception is that the best practice is to use the first two ways (I'll use one or the other depending on the specific package full name and the number of symbols I need from it). I'd use the third only in a language which doesn't provide the first and hunt for supporting tools to write the import statements. And in my opinion the fourth should be reserved to package designed with than import in mind, for instance if all exported symbols start with a prefix or contains the name of the package. My questions: what is in your opinion the best practice for your favorite languages? what would you suggest in a new language? what would you suggest in an old language adding such a feature?

  • Why is win32com so much slower than xlrd?

    - by Josh
    I have the same code, written using win32com and xlrd. xlrd preforms the algorithm in less than a second, while win32com takes minutes.

  • What are the use cases for this static reflection code?

    - by Maslow
    This is Oliver Hanappi's static reflection code he posted on stackoverflow private static string GetMemberName(Expression expression) { switch (expression.NodeType) { case ExpressionType.MemberAccess: var memberExpression = (MemberExpression)expression; var supername = GetMemberName(memberExpression.Expression); if (String.IsNullOrEmpty(supername)) return memberExpression.Member.Name; return String.Concat(supername, '.', memberExpression.Member.Name); case ExpressionType.Call: var callExpression = (MethodCallExpression)expression; return callExpression.Method.Name; case ExpressionType.Convert: var unaryExpression = (UnaryExpression)expression; return GetMemberName(unaryExpression.Operand); case ExpressionType.Parameter: return String.Empty; default: throw new ArgumentException("The expression is not a member access or method call expression"); } } I have the public wrapper methods: public static string Name<T>(Expression<Action<T>> expression) { return GetMemberName(expression.Body); } public static string Name<T>(Expression<Func<T, object>> expression) { return GetMemberName(expression.Body); } then added my own method shortcuts public static string ClassMemberName<T>(this T sourceType,Expression<Func<T,object>> expression) { return GetMemberName(expression.Body); } public static string TMemberName<T>(this IEnumerable<T> sourceList, Expression<Func<T,object>> expression) { return GetMemberName(expression.Body); } What are examples of code that would necessitate or take advantage of the different branches in the GetMemberName(Expression expression) switch? what all is this code capable of making strongly typed?

  • Can/Should you throw exceptions in a c# switch statement?

    - by Kettenbach
    Hi All, I have an insert query that returns an int. Based on that int I may wish to throw an exception. Is this appropriate to do within a switch statement? switch (result) { case D_USER_NOT_FOUND: throw new ClientException(string.Format("D User Name: {0} , was not found.", dTbx.Text)); case C_USER_NOT_FOUND: throw new ClientException(string.Format("C User Name: {0} , was not found.", cTbx.Text)); case D_USER_ALREADY_MAPPED: throw new ClientException(string.Format("D User Name: {0} , is already mapped.", dTbx.Text)); case C_USER_ALREADY_MAPPED: throw new ClientException(string.Format("C User Name: {0} , is already mapped.", cTbx.Text)); default: break; } I normally add break statements to switches but they will not be hit. Is this a bad design? Please share any opinions/suggestions with me. Thanks, ~ck in San Diego

I'd like to find out which recipes I can made with components which I have. It's not easy - but possible - I made a SQL view, which gets the solution. But I'm learning python and Django so I'd like to make it Django-style ;D The concept of solution: get the set of recipes which has at last one component: list_of_available_components = ReceiptComponent.objects.filter(product__in=list_of_available_products).distinct() list_of_related_receipts = Receipt.objects.filter(receiptcomponent__in = list_of_available_components).distinct() get recipes (from list_of_related_receipts) which has not at last one component list_of_incomplete_recipes = (SELECT * FROM drinkbook_receiptcomponent LEFT JOIN drinkstore_stock_products USING(product_id) WHERE drinkstore_stock_products.stock_id IS NULL AND receipt_id IN (SELECT receipt_id FROM drinkbook_receiptcomponent JOIN drinkstore_stock_products USING(product_id))) get recipes (from list_of_related_receipts) which are not in "list_of_incomplete_recipes"

  • How to do a Postgresql subquery in select clause with join in from clause like SQL Server?

    - by Ricardo
    I am trying to write the following query on postgresql: select name, author_id, count(1), (select count(1) from names as n2 where n2.id = n1.id and t2.author_id = t1.author_id ) from names as n1 group by name, author_id This would certainly work on Microsft SQL Server but it does not at all on postegresql. I read its documentation a bit and it seems I could rewrite it as: select name, author_id, count(1), total from names as n1, (select count(1) as total from names as n2 where n2.id = n1.id and n2.author_id = t1.author_id ) as total group by name, author_id But that returns the following error on postegresql: "subquery in FROM cannot refer to other relations of same query level". So I'm stuck. Does anyone know how I can achieve that? Thanks
