  • Save jQuery callback functions in a separate file

    - by Danny Herran
    Probably I missed something, but lets say I have this: $('a.delete').click(function(){ resp=window.confirm("Are you sure you want to delete this?"); if(resp) return true; else return false; } Now, I want to save that callback function into a separate js file, because I will use it in several pages. My logic told me to do this: $('a.del').click(delete_element()); Having my js file like this: function delete_element(){ resp=window.confirm("Are you sure you want to delete this?"); if(resp) return true; else return false; } This doesn't work. Everytime my page loads, it displays the confirm window, even if I haven't clicked the link. It is clear that my logic failed this time. What am I missing?

  • MVC 3 ModelView passing parameters between view & controller

    - by Tobias Vandenbempt
    I've been playing with MVC 3 in a test project and have the following issue. I have Group & Subscriber entities and those are coupled through a SubscriberGroup table. Using the DetailView of Group I open a view of SubscriberGroup containing all subscribers. This list has the option to filter. So far it all works, however when I call the AddToGroup method on the controller it fails. Specifically it goes into the method but doesn't pass the subscriberCheckedModels list. Am I doing something wrong? View: SubscriberGroup Index.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.master" Inherits="System.Web.Mvc.ViewPage<Mail.Models.SubscriberCheckedListViewModel>" %> … <h2 class="common-box-title"> Add Subscribers to Group</h2> <p> <% using (Html.BeginForm("Index", "SubscriberGroup")) { %> <input name="filter" id="filter" type="text" /> <input type="submit" value="Search" /> <%} %> </p> <% using (Html.BeginForm("AddToGroup", "SubscriberGroup", Model,FormMethod.Get, null)) { %> <fieldset> <div style="display: inline-block; width: 70%; vertical-align: top;"> <% if (Model.subscribers.Count() != 0) { %> <table class="hor-minimalist-b"> <tr> <th> Add To Group </th> <th> Full Name </th> <th> Email </th> <th> Customer </th> </tr> <% foreach (var item in Model.subscribers) { %> <tr> <td> <%= Html.CheckBoxFor(modelItem => item.AddToGroup)%> </td> <td> <%= Html.DisplayFor(modelItem => item.subscriber.LastName)%> <%= Html.ActionLink(item.subscriber.FirstName + " " + item.subscriber.LastName, "Details", new { id = item.subscriber.SubscriberID })%> </td> <td> <%: Html.DisplayFor(modelItem => item.subscriber.Email)%> </td> <td> <%: Html.DisplayFor(modelItem => item.subscriber.Customer.Company)%> <%= Html.HiddenFor(modelItem => item.subscriber) %> </td> </tr> <% } %> <% ViewBag.subscribers = Model.subscribers; %> probeersel <%= Html.HiddenFor(model => model.subscribers) %> probeersel </table> <%} %> <%else { %> <p> No subscribers found.</p> <%} %> <input type="submit" value="Add Subscribers" /> </div> </fieldset> <%} %> Controller: SubscriberGroupController using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Security; using Mail.Models; namespace Mail.Controllers { public class SubscriberGroupController : Controller { private int groupID; private MailDBEntities db = new MailDBEntities(); // // GET: /SubscriberGroup/ public ActionResult Index(int id) { groupID = id; MembershipUser myObject = Membership.GetUser(); Guid UserID = Guid.Parse(myObject.ProviderUserKey.ToString()); UserCustomer usercustomer = db.UserCustomers.Single(s => s.UserID == UserID); var subscribers = from subscriber in db.Subscribers where (subscriber.CustomerID == usercustomer.CustomerID) | (subscriber.CustomerID == 0) select new SubscriberCheckedModel { subscriber = subscriber, AddToGroup = false }; SubscriberCheckedListViewModel test = new SubscriberCheckedListViewModel(); test.subscribers = subscribers; return View(test); } [HttpPost] public ActionResult Index(string filter) { MembershipUser myObject = Membership.GetUser(); Guid UserID = Guid.Parse(myObject.ProviderUserKey.ToString()); UserCustomer usercustomer = db.UserCustomers.Single(s => s.UserID == UserID); var subscribers2 = from subscriber in db.Subscribers where ((subscriber.FirstName.Contains(filter)|| subscriber.LastName.Contains(filter)) && (subscriber.CustomerID == usercustomer.CustomerID || subscriber.CustomerID == 0)) select new SubscriberCheckedModel { subscriber = subscriber, AddToGroup = false }; SubscriberCheckedListViewModel test = new SubscriberCheckedListViewModel(); test.subscribers = subscribers2.ToList(); return View(test); } [HttpPost] public ActionResult AddToGroup(SubscriberCheckedListViewModel test) { //test is null return RedirectToAction("Details", "Group", new { id = groupID }); } } } ViewModel: SubscriberGroupModel using System.Collections.Generic; using Mail; namespace Mail.Models { public class SubscriberCheckedModel { public Subscriber subscriber { get; set; } public bool AddToGroup { get; set; } } public class SubscriberCheckedListViewModel { public IEnumerable<SubscriberCheckedModel> subscribers { get; set; } } }

  • scope of variables in JavaScript callback functions

    - by Ethan
    I expected the code below to alert "0" and "1", but it alert "2" twice. I don't the reason. Don't know if it is a problem of jQuery. Also, please help me to edit title and tags of this post if they are inaccurate. <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(function() { for (var i=0; i<2; i++) { $.get('http://www.google.com/', function() { alert(i); }); } }); </script> </head> <body> </body> </html>

  • Entity Framework How to specify paramter type in generated SQL (SQLServer 2005) Nvarchar vs Varchar

    - by Gratzy
    In entity framework I have an Entity 'Client' that was generated from a database. There is a property called 'Account' it is defined in the storage model as: <Property Name="Account" Type="char" Nullable="false" MaxLength="6" /> And in the Conceptual Model as: <Property Name="Account" Type="String" Nullable="false" /> When select statements are generated using a variable for Account i.e. where m.Account == myAccount... Entity Framework generates a paramaterized query with a paramater of type NVarchar(6). The problem is that the column in the table is data type of char(6). When this is executed there is a large performance hit because of the data type difference. Account is an index on the table and instead of using the index I believe an Index scan is done. Anyone know how to force EF to not use Unicode for the paramater and use Varchar(6) instead?

  • Initializing objects on the fly

    - by pocoa
    I have a vector called players and a class called Player. And what I'm trying to do is to write: players.push_back(Player(name, Weapon(bullets))); So I want to be able to create players in a loop. But I see an error message says "no matching function for call Player::Player..." Then I've changed that to: Weapon w(bullets); Player p(name, w); players.push_back(p); Here is my Player definition: class Player { public: Player(string &name, Weapon &weapon); private string name; Weapon weapon; } I'm just trying to learn what is the difference between these definitions. And is this the right way to pass an object to an object constructor. Note: These are not my actual class definitions. I'm just trying to learn something about object oriented programming in C++ with coding it. I mean I know that Weapon should be initialized in Player :)

  • call multiple c++ functions in python using threads

    - by wiso
    Suppose I have a C(++) function taking an integer, and it is bound to (C)python with python api, so I can call it from python: import c_module c_module.f(10) now, I want to parallelize it. The problem is: how does the GIL work in this case? Suppose I have a queue of numbers to be processed, and some workers (threading.Thread) working in parallel, each of them calling c_module.f(number) where number is taken from a queue. The difference with the usual case, when GIL lock the interpreter, is that now you don't need the interpreter to evaluate c_module.f because it is compiled. So the question is: in this case the processing is really parallel?

    Is there any way to combine all of this to reduce the amount of js? This is just an example of some of the jquery dialogs I have in my site, there are a few more too.

  • C# 4.0: Can I use a Color as an optional parameter with a default value?

    - by DTown
    public void log(String msg, Color c = Color.black) { loggerText.ForeColor = c; loggerText.AppendText("\n" + msg); } This results in an error that c must be a compile-time constant. I've read up on this a little and most examples are dealing with strings and ints. I've figured out I can use the colorconverter class but I'm not sure it will be very efficient. Is there a way to just pass a basic color as an optional parameter? public void log(String msg, String c = "Black") { ColorConverter conv = new ColorConverter(); Color color = (Color)conv.ConvertFromString(c); loggerText.ForeColor = color; loggerText.AppendText("\n" + msg); }

  • llvm clang struct creating functions on the fly

    - by anon
    I'm using LLVM-clang on Linux. Suppose in foo.cpp I have: struct Foo { int x, y; }; How can I create a function "magic" such that: typedef (Foo) SomeFunc(Foo a, Foo b); SomeFunc func = magic("struct Foo { int x, y; };"); so that: func(SomeFunc a, SomeFunc b); // returns a.x + b.y; ? Note: So basically, "magic" needs to take a char*, have LLVM parse it to get how C++ lays out the struct, then create a function on the fly that returns a.x + b.y; Thanks!

  • ajaxSubmit options success & error functions aren't fired

    - by Thommy Tomka
    jQuery 1.7.2 jQuery Validate 1.1.0 jQuery Form 3.18 Wordpress 3.4.2 I am trying to code a contact/ mail form in above environment/ with above jQuery libs. Now I am having a problem with the jQuery Form JS: I have taken the original code from the developers page for ajaxSubmit and only altered the target option to an ID which exists in my HTML source and replaced $ with jQuery in function showRequest. The problem is, that the function namend after success: does not fire. I tried the same with error: and again nothing fired. Only complete: did and the function I placed there alerted the responseText from the receiving script. Does anyone has an idea whats going wrong? Thanks in advance! Thomas jQuery(document).ready(function() { var options = { target: '#mail-status', // target element(s) to be updated with server response beforeSubmit: showRequest, // pre-submit callback success: showResponse, // post-submit callback // other available options: //url: url // override for form's 'action' attribute //type: type // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) //clearForm: true // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; jQuery("#mailform").validate( { submitHandler: function(form) { jQuery(form).ajaxSubmit(options); }, errorPlacement: function(error, element) { }, rules: { author: { minlength: 2, required: true }, email: { required: true, email: true }, comment: { minlength: 2, required: true } }, highlight: function(element) { jQuery(element).addClass("e"); jQuery(element.form).find("label[for=" + element.id + "]").addClass("e"); }, unhighlight: function(element) { jQuery(element).removeClass("e"); jQuery(element.form).find("label[for=" + element.id + "]").removeClass("e"); } }); }); // pre-submit callback function showRequest(formData, jqForm, options) { // formData is an array; here we use $.param to convert it to a string to display it // but the form plugin does this for you automatically when it submits the data var queryString = jQuery.param(formData); // jqForm is a jQuery object encapsulating the form element. To access the // DOM element for the form do this: // var formElement = jqForm[0]; alert('About to submit: \n\n' + queryString); // here we could return false to prevent the form from being submitted; // returning anything other than false will allow the form submit to continue return true; } // post-submit callback function showResponse(responseText, statusText, xhr, $form) { // for normal html responses, the first argument to the success callback // is the XMLHttpRequest object's responseText property // if the ajaxSubmit method was passed an Options Object with the dataType // property set to 'xml' then the first argument to the success callback // is the XMLHttpRequest object's responseXML property // if the ajaxSubmit method was passed an Options Object with the dataType // property set to 'json' then the first argument to the success callback // is the json data object returned by the server alert('status: ' + statusText + '\n\nresponseText: \n' + responseText + '\n\nThe output div should have already been updated with the responseText.'); }

  • POST parameters strangely parsed inside phantomjs

    - by user61629
    I am working with PHP/CURL and would like to send POST data to my phantomjs script, by setting the postfields array below: In my php controller I have: $data=array('first' => 'John', 'last' => 'Smith'); $url='http://localhost:7788/'; $output = $this->my_model->get_data($url,$data); In my php model I have: public function get_data($url,$postFieldArray) { $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldArray); curl_setopt($ch, CURLOPT_URL, $url); $output = curl_exec($ch); In my phantomJS script that I am running locally I have: // import the webserver module, and create a server var server = require('webserver').create(); var port = require('system').env.PORT || 7788; console.log("Start Application"); console.log("Listen port " + port); // Create serever and listen port server.listen(port, function(request, response) { // Print some information Just for debbug console.log("We got some requset !!!"); console.log("request method: ", request.method); // request.method POST or GET if(request.method == 'POST' ){ console.log("POST params should be next: "); console.log("POST params: ",request.post); exit; } I first start and run the phantomjs script (myscript.js) from the command line, then I run my php script.

  • PHP exec() and system() functions always return false in IIS

    - by Loftx
    Hi there, I'm trying to use the PHP exec() or system() (or any other similar function) to run a batch file, but I can't seem to get these to return anything. The simplest example I've seen is this, which outputs nothing: <?php echo system('dir'); ?> The script is running on a windows XP machine on IIS with PHP installed and I've also tried it on my shared hosting account running windows 2003 server/IIS. Can anyone suggest what I need to do to get this working, or provide any commands I can use for troubleshooting? Cheers, Tom
