  • Syntax error. Help with one small JS snippet :(

    - by Bogdan
    Hey guys. I don't know much JS, but I wanted to do some quick work with jQuery. But I've been staring at this for about an hour and I don't understand what I missed: <script type="text/javascript"> $('#qty_6035').change(function () { var substractedQty, stockQty, remQty; substractedQty = (int) $('#qty_6035').val(); // missing ; before statement stockQty = (int) $('#orig_qty_6035').val(); $('#rem_qty_6035').html(stockQty-substractedQty); }); </script> jQuery library is included at the beggining of the document. Thanks.

  • Logic: Best way to sample & count bytes of a 100MB+ file

    - by Jami
    Let's say I have this 170mb file (roughly 180 million bytes). What I need to do is to create a table that lists: all 4096 byte combinations found [column 'bytes'], and the number of times each byte combination appeared in it [column 'occurrences'] Assume two things: I can save data very fast, but I can update my saved data very slow. How should I sample the file and save the needed information? Here're some suggestions that are (extremely) slow: Go through each 4096 byte combinations in the file, save each data, but search the table first for existing combinations and update it's values. this is unbelievably slow Go through each 4096 byte combinations in the file, save until 1 million rows of data in a temporary table. Go through that table and fix the entries (combine repeating byte combinations), then copy to the big table. Repeat going through another 1 million rows of data and repeat the process. this is faster by a bit, but still unbelievably slow This is kind of like taking the statistics of the file. NOTE: I know that sampling the file can generate tons of data (around 22Gb from experience), and I know that any solution posted would take a bit of time to finish. I need the most efficient saving process

  • c# creating a database query METHOD

    - by Sinaesthetic
    I'm not sure if im delluded but what I would like to do is create a method that will return the results of a query, so that i can reuse the connection code. As i understand it, a query returns an object but how do i pass that object back? I want to send the query into the method as a string argument, and have it return the results so that I can use them. Here's what i have which was a stab in the dark, it obviously doesn't work. This example is me trying to populate a listbox with the results of a query; the sheet name is Employees and the field/column is name. The error i get is "Complex DataBinding accepts as a data source either an IList or an IListSource.". any ideas? public Form1() { InitializeComponent(); openFileDialog1.ShowDialog(); openedFile = openFileDialog1.FileName; lbxEmployeeNames.DataSource = Query("Select [name] FROM [Employees$]"); } public object Query(string sql) { System.Data.OleDb.OleDbConnection MyConnection; System.Data.OleDb.OleDbCommand myCommand = new System.Data.OleDb.OleDbCommand(); string connectionPath; //build connection string connectionPath = "provider=Microsoft.Jet.OLEDB.4.0;Data Source='" + openedFile + "';Extended Properties=Excel 8.0;"; MyConnection = new System.Data.OleDb.OleDbConnection(connectionPath); MyConnection.Open(); myCommand.Connection = MyConnection; myCommand.CommandText = sql; return myCommand.ExecuteNonQuery(); }

  • Line by Line explanation of "Javascript: Good Parts" example?

    - by Matrym
    I'm reading "Javascript: The Good Parts" and am totally baffled by what's really going on here. A more detailed and/or simplified explanation would be greatly appreciated. // BAD EXAMPLE // Make a function that assigns event handler functions to an array of nodes the wrong way. // When you click on a node, an alert box is supposed to display the ordinal of the node. // But it always displays the number of nodes instead. var add_the_handlers = function (nodes) { var i; for (i = 0; i < nodes.length; i += 1) { nodes[i].onclick = function (e) { alert(i); } } }; // END BAD EXAMPLE The add_the_handlers function was intended to give each handler a unique number (i). It fails because the handler functions are bound to the variable i, not the value of the variable i at the time the function was made: // BETTER EXAMPLE // Make a function that assigns event handler functions to an array of nodes the right way. // When you click on a node, an alert box will display the ordinal of the node. var add_the_handlers = function (nodes) { var i; for (i = 0; i < nodes.length; i += 1) { nodes[i].onclick = function (i) { return function (e) { alert(i); }; }(i); } }; Now, instead of assigning a function to onclick, we define a function and immediately invoke it, passing in i. That function will return an event handler function that is bound to the value of i that was passed in, not to the i defined in add_the_handlers. That returned function is assigned to onclick.

  • WebView not responding when called from a method

    - by AragornSG
    I have an app with tabbar and webview. I'm trying to make the app come back to default url each time user taps the bar. Right now I'm intercepting taps and launching a method, however it's not affecting my webview. The same syntax for calling webview from awakeFromNib works, so I don't have a clue what's up. I suspect it's something to do with how I call the method, but I don't know what. Here is the code: #import "SecondViewController.h" @implementation SecondViewController - (void)awakeFromNib { NSString *loadURL = [NSString stringWithFormat:@"http://pageurl"]; // [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:loadURL]]]; SecondViewController *ptr = [[SecondViewController alloc] init]; [ptr goToPage]; } - (void) goToPage { NSLog(@"go to page"); NSString *newURL = [NSString stringWithFormat:@"http://pageurl"]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } Thanks fot your help!

  • Pass form object value to static method

    - by jrubengb
    Hi, I need to take a form object value and pass it into a static method: public void SetCalendarStartSafe(DateTime startDateSafe) { startDateSafe = calendarStart.Value; } private static DataTable GetData() { frmMain frm = new frmMain(); DateTime startDate = new frmMain(); frm.SetCalendarStartSafe(startDate); } However I keep getting today's current date whenever I try this approach, even if the specified calendar date on the form is different. How can I can the user-specified calendar date from the original frmMain object? Thanks in advance for any guidance.

  • Behaviour to simulate an enum implementing an interface

    - by fearofawhackplanet
    Say I have an enum something like: enum OrderStatus { AwaitingAuthorization, InProduction, AwaitingDespatch } I've also created an extension method on my enum to tidy up the displayed values in the UI, so I have something like: public static string ToDisplayString(this OrderStatus status) { switch (status) { case Status.AwaitingAuthorization: return "Awaiting Authorization"; case Status.InProduction: return "Item in Production"; ... etc } } Inspired by the excellent post here, I want to bind my enums to a SelectList with an extension method: public static SelectList ToSelectList<TEnum>(this TEnum enumObj) however, to use the DisplayString values in the UI drop down I'd need to add a constraint along the lines of : where TEnum has extension ToDisplayString Obviously none of this is going to work at all with the current approach, unless there's some clever trick I don't know about. Does anyone have any ideas about how I might be able to implement something like this?

  • Create an event to recognise when text on a page changes?

    - by DaveDev
    There's a page that I'm trying to trigger a jQuery event for when a certain span's value changes to 1. There's a countdown timer on the page. When the timer reaches 1, I'd like to trigger a click event. The difficulty I'm having is getting a script that i'm running via Jash to know when the timer changes to 1. The value of the timer can read with: $('#tCounter_474754 .bid_time_highlight').text(); But how can I get jQuery to trigger the click when this timer reaches 1?

  • Any dynamic database frontend tool from which you can update directly?

    - by Enjoy coding
    Hi Gurus, This is with reference to this question where I got one tabular report format. I need to update the user entered values correctly back to the same table rows. I am in the process of doing this by using general form post data methods by using some logics which I think will not be easy to maintain. So, just out of curiosity, Is there a front end creator javascript libraries or frameworks which can create the front end for any query's resultset and updates the corresponding rows when the user updates them from front end. This need not have all the full functionality, any one usable, customizable thing will reduce the code maintenance problems. I have googled for some javascript libraris for this but not able to get which will be suitable. Please suggest any useful tools. My environment is Mysql, PHP, JQuery, XAMPP server on Windows. Is JQuery provides one. Thanks in advance.

  • Is there anything wrong with a class with all static methods?

    - by MatthewMartin
    I'm doing code review and came across a class that uses all static methods. The entrance method takes several arguments and then starts calling the other static methods passing along all or some of the arguments the entrance method received. It isn't like a Math class with largely unrelated utility functions. In my own normal programming, I rarely write methods where Resharper pops and says "this could be a static method", when I do, they tend to be mindless utility methods. Is there anything wrong with this pattern? Is this just a matter of personal choice if the state of a class is held in fields and properties or passed around amongst static methods using arguments?

  • Form variable does not refresh with ajax call

    - by ChrisOPeterson
    I'm building a simple email sending form and wanted to make it with ajax. The form submits correctly the first time but if you make any subsequent changes to the text in the form and then submit again then jquery does not pick up on the changes and posts the old data. Whats going on? <script type="text/javascript"> var $j = jQuery.noConflict(); $j(document).ready(function() { var submit_url = "mail_submit.php"; var send_email = $j("#sendemail"); send_email.click(function() { var form = $j("#post"); $j.post(submit_url, form.serialize(), function(data) { alert(data); }); }); });

  • If I cast an IQueryable as an IEnumerable then call a Linq extension method, which implementation gets called?

    - by James Morcom
    Considering the following code: IQueryable<T> queryable; // something to instantiate queryable var enumerable = (IEnumerable<T>) queryable; var filtered = enumerable.Where(i => i > 3); In the final line, which extension method gets called? Is it IEnumerable<T>.Where(...)? Or will IQueryable<T>.Where(...) be called because the actual implementation is still obviously a queryable? Presumably the ideal would be for the IQueryable version to be called, in the same way that normal polymorphism will always use the more specific override. In Visual Studio though when I right-click on the Where method and "Go to Definition" I'm taken to the IEnumerable version, which kind of makes sense from a visual point-of-view. My main concern is that if somewhere in my app I use Linq to NHibernate to get a Queryable, but I pass it around using an interface that uses the more general IEnumerable signature, I'll lose the wonders of deferred database execution!

  • Save the contents of manipulated div to a variable and pass to php file

    - by Danielle Zarcaro
    I have tried to use AJAX, but nothing I come up with seems to work correctly. I am creating a menu editor. I echo part of a file using php and manipulate it using javascript/jquery/ajax (I found the code for that here: http://www.prodevtips.com/2010/03/07/jquery-drag-and-drop-to-sort-tree/). Now I need to get the edited contents of the div (which has an unordered list in it) I am echoing and save it to a variable so I can write it to the file again. I couldn't get that resource's code to work so I'm trying to come up with another solution. If there is a code I can put into the $("#save").click(function(){ }); part of the javascript file, that would work, but the .post doesn't seem to want to work for me. If there is a way to initiate a php preg_match in an onclick, that would be the easiest. Any help would be greatly appreciated.

  • Execute js on DOMContentLoaded in ff-extension

Any ideas how to call onPageLoad each time DOM content is reloaded?

  • Why can't I set attribute "TYPE" of LI element in IE?

    - by Petr Urban
    Hello, I've just come to an unusual beghavior of Internet Explorer IE (v8.0.6001.18904). When I try to set "type" attribute of any <LI> element, it will result into error. I used jQuery (v1.32): $("<li>").attr("type", "test"); The same thing works for DIV. LI element does not seem to have "type" attribute reserved by HTML or XHTML definitions. It also might be jQuery issue. Solution is simple - just use another attribute name :-) But is there someone out there who knows WHY does this error occur? Could it happen with another attribute names? Why the error comes with LI element only?

  • override __set in __construct() in php?

    - by user151841
    I have a class based on database values. I'm using __set to automatically sync database values with the class properties. Set checks an array of database fields that it is allowed to update in the database. The field 'id' isn't in the list, so __set will throw an exception if you try to do $objDbRow->id = 5;. However, there is one time when I do want to set the id property of the object, and that's on instantiation. So in __constuct, I have $this->id = $id (where $id is passed to __construct). However, __set seems to be intercepting the setting here, because an exception is being thrown on construction. What's the way to get around this? I suppose I also have a boolean flag, like $instantiated, that __set() would check before it does it's field whitelist checking. But that feels inelegant.

  • Perform function on form submit

    - by flight643
    Hopefully this is a pretty simple question! I've got the code working in jQuery to listen for a specific form on a page to be submitted and perform an alert when it is.. I.e.: The form itself doesn't have a name so I am targetting the form within a specific form ID. $("#content form").submit(function() { alert("lorem ipsum dolor?"); }); What would be the syntax for performing this in javascript alone without using jquery? For example, I have this code (below) and just am unsure of how to listen for the form to be submitted to perform an action.. var submitform = document.getElementById("content").getElementsByTagName("form"); Thanks!

  • Start a thread using a method pointer

    - by Michael
    Hi ! I'm trying to develop a thread abstraction (POSIX thread and thread from the Windows API), and I would very much like it to be able to start them with a method pointer, and not a function pointer. What I would like to do is an abstraction of thread being a class with a pure virtual method "runThread", which would be implanted in the future threaded class. I don't know yet about the Windows thread, but to start a POSIX thread, you need a function pointer, and not a method pointer. And I can't manage to find a way to associate a method with an instance so it could work as a function. I probably just can't find the keywords (and I've been searching a lot), I think it's pretty much what Boost::Bind() does, so it must exist. Can you help me ?

  • How to I preload images where it actually forces the images to load before continuing (html/javascri

    - by Mr. Flibble
    I want to preload images but ensure they are loaded before continuing. How can I do this? The following does not work as it sends off the load request only, but doesn't wait till the image is loaded. So it is possible that the image isn't loaded when requested soon after. jQuery.preloadImages = function () { for (var i = 0; i < arguments.length; i++) { jQuery("<img>").attr("src", arguments[i]); } } $.preloadImages("img1.jpg","img2.jpg");
