  • ASP.NET MVC - how to make users confirm the delete

    - by H4mm3rHead
    He, I have this page where i have checkboxes next to every item in a table, and want to allow the user to select some of them and press my delete button. I just cant come up with the jquery for making the confirm window and submitting only if 'yes' is pushed - this is my page <%Html.BeginForm(); %> <%List<ShopLandCore.Model.SLGroup> groups = (List<ShopLandCore.Model.SLGroup>)Model; %> <%Html.RenderPartial("AdminWorkHeader"); %> <table width="100%" id="ListTable" cellpadding="0" cellspacing="0"> <tr> <td colspan="5" class="heading"> <input type="submit" name="closeall" value="Close selected" /> <input type="submit" name="deleteall" value="Delete selected" /> </td> </tr> <tr> <th width="20px"> </th> <th> Name </th> <th> Description </th> <th width="150px"> Created </th> <th width="150px"> Closed </th> </tr> <%foreach (ShopLandCore.Model.SLGroup g in groups) { %> <tr> <td> <%=Html.CheckBox(g.Id.ToString()) %> </td> <td> <%=g.Name %> </td> <td> <%=g.Description %> </td> <td> <%=g.Created %> </td> <td> <%=g.Closed %> </td> </tr> <%} %> </table> <%Html.EndForm(); %> Please note that its only for the delete that it should confirm, and not necessarily for the close button.

  • textarea doesnt return value

    - by toingbou
    Im using a code editor codepress in all of my textareas, but no textarea return a value. I think the different name and id is the problem. Example: <textarea name="content_text" rows="20" cols="50" class="codepress sql" id="myCpWindow"></textarea> I have read somewhere in here to use a hidden input to transfer the textarea's value, but i cant do it myself! ayhelp?

  • JSunit usability

    - by stevebot
    Is JSunit really a direct port of Junit to Javascript? So I have heard, but I am wondering why my company is not using it. My company has lots of smart minds, so If we are not using it I wonder if there are any major issues with Jsunit as a javascript test harness. Input would be much appreciated. thanks!

  • PHP Changing Class Variables Outside of Class

    - by Jamie Bicknell
    Apologies for the wording on this question, I'm having difficulties explaining what I'm after, but hopefully it makes sense. Let's say I have a class, and I wish to pass a variable through one of it's methods, then I have another method which outputs this variable. That's all fine, but what I'm after is that if I update the variable which was originally passed, and do this outside the class methods, it should be reflected in the class. I've created a very basic example: class Test { private $var = ''; function setVar($input) { $this->var = $input; } function getVar() { echo 'Var = ' . $this->var . '<br />'; } } If I run $test = new Test(); $string = 'Howdy'; $test->setVar($string); $test->getVar(); I get Var = Howdy However, this is the flow I would like: $test = new Test(); $test->setVar($string); $string = 'Hello'; $test->getVar(); $string = 'Goodbye'; $test->getVar(); Expected output to be Var = Hello Var = Goodbye I don't know what the correct naming of this would be, and I've tried using references to the original variable but no luck. I've come across this in the past, with the PDO prepared statements, see Example #2 $stmt = $dbh->prepare("INSERT INTO REGISTRY (name, value) VALUES (?, ?)"); $stmt->bindParam(1, $name); $stmt->bindParam(2, $value); // insert one row $name = 'one'; $value = 1; $stmt->execute(); // insert another row with different values $name = 'two'; $value = 2; $stmt->execute(); I know I can change the variable to public and do the following, but it isn't quite the same as how the PDO class handles it, and I'm really looking to mimic that behaviour. $test = new Test(); $test->setVar($string); $test->var = 'Hello'; $test->getVar(); $test->var = 'Goodbye'; $test->getVar(); Any help, ideas, pointers, or advice would be greatly appreciated, thanks.

  • What is the best way to create a debugging web page for a computation in Java?

    - by Shooshpanchick
    I'm developing a website that uses some complex computations (NLP-related). My customer wants to have "debugging" webpages for some of these computations where he can run them with arbitrary input and see all the intermediate results that occur during computation. Before this request all of the computations were encapsulated in beans and intermediate results were logged into general log. What is the best way to capture all these results on Java level to render them as webpage?

  • Passing function-specific variables

    - by Simon Carlson
    Say I got two functions that looks like this: function main(Index) { doStuff(); } function doStuff() { if(Index == 1) { document.write("Hello world!") } } And some HTML: <input type="button" value="Click me" onclick="main(1)" /> I realize this is a very stupid way to use function-specific variables and such, but it's just out of curiosity. So is it possible to pass the variable Index from the main function to the doStuff function?

  • error: expected `;' before '{' token - What is the cause?

    - by melee
    Here is my implementation file: using namespace std; #include <iostream> #include <iomanip> #include <string> #include <stack> //line 5 #include "proj05.canvas.h" //----------------Constructor----------------// Canvas::Canvas() //line 10 { Title = ""; Nrow = 0; Ncol = 0; image[][100]; // line 15 position.r = 0; position.c = 0; } //-------------------Paint------------------// line 20 void Canvas::Paint(int R, int C, char Color) { cout << "Paint to be implemented" << endl; } The errors I'm getting are these: proj05.canvas.cpp: In function 'std::istream& operator>>(std::istream&, Canvas&)': proj05.canvas.cpp:11: error: expected `;' before '{' token proj05.canvas.cpp:22: error: a function-definition is not allowed here before '{' token proj05.canvas.cpp:24: error: expected `}' at end of input proj05.canvas.cpp:24: error: expected `}' at end of input These seem like simple syntax errors, but I am not sure what's wrong. Could someone decode these for me? I'd really appreciate it, thanks for your time! EDIT Here is the definition of Canvas in my .h file: #ifndef CANVAS_H #define CANVAS_H #include <iostream> #include <iomanip> #include <string> #include <stack> class Canvas { public: Canvas(); void Paint(int R, int C, char Color); const int Nrow; const int Ncol; string Title; int image[][100]; stack<int> path; struct PixelCoordinates { unsigned int r; unsigned int c; } position; }; #endif

  • What is the difference between the Control.Enter and Control.GotFocus events?

    - by jameswelle
    This may be a basic question, but I have to admit I've never truly understood what the difference between the Control.Enter and Control.GotFocus events is. http://msdn.microsoft.com/en-us/library/system.windows.forms.control.enter.aspx http://msdn.microsoft.com/en-us/library/system.windows.forms.control.gotfocus.aspx Is it a differentiation between capturing keyboard or mouse input or something else?

  • Is it possible to use SQL XML to insert, and get output from each record?

    - by nbolton
    I would like to perform a SQL XML insert (on MSSQL), and in this case I need to insert a list of files into the DB (this is simple enough). However, there's an auto generated PK column (ID), and I need the ID for each newly created filename without performing a 2nd query. Is this possible? I guess it doesn't matter if the result is/isn't XML, but the input certainly has to be.

  • Alter a function as a parameter before evaluating it?

    - by Shane
    Is there any way, given a function passed as a parameter, to alter its input parameter string before evaluating it? Here's pseudo-code for what I'm hoping to achieve: test.func <- function(a, b) { # here I want to alter the b expression before evaluating it: b(..., val1=a) } Given the function call passed to b, I want to add in a as another parameter without needing to always specify ... in the b call. So the output from this test.func call should be: test.func(a="a", b=paste(1, 2)) "1" "2" "a"

  • Best way to manage JSON object via GET and POST in php.

    - by Kucebe
    My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'JSON_Obj' : myJSON_Obj }. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['JSON_Obj'] or $_POST['JSON_Obj']. For example, using file_get_contents("php://input"), i can manage POST requests in that way, but in GET format it doesn't work. Any suggestions?

  • Are parametrized calls/sanitization/escaping characters necessary for hashed password fields in SQL queries?

    - by Computerish
    When writing a login system for a website, it is standard to use some combination of parameterized calls, sanitizing the user input, and/or escaping special characters to prevent SQL injection attacks. Any good login system, however, should also hash (and possibly salt) every password before it goes into an SQL query, so is it still necessary to worry about SQL injection attacks in passwords? Doesn't a hash completely eliminate any possibility of an SQL injection attack on its own?

  • CS Majors: Hardest concept(s) you learned in school?

    - by Mark Lubin
    For the CS majors out there what were the hardest CS classes or concepts that you learned in your undergraduate schooling? Did you find once you learned the basics,(data structs, OOP fundamentals, discrete math, pointers, recursion, etc) the rest followed naturally or did you hit a wall at any point in your higher classes like OS'es and Compilers? Thanks for the input!
