MVC :: Posting List Of Checked Items To Controller Action Using JQuery Post?
Feb 16, 2011
I got a list of checkboxes on my form, and a jquery script that catch a button click to get all the selected items (in an array) and post to a controller action.
This is my script: (yes A, looked at your sample but cannot get this to work)
[Code]....
That alert will print out correctly (like 1,3,5).
However when the above post hit my controller action, "selectedInvestments" are null, which I can't figure out why (back to my tekpub jquery videos, can't go on like this)
ia ma working on an asp.net mvc 2 app and i have a Users view, displaying all the users of the database. Then, i would like to add the ablility to display "users starting with fisrt name" capabaility on the same view. For this i created a list of all english leters that actually are links (<a href="#">A</a>, etc...)
I managed to handle the click event of each one of the letters and get the corresponding letter via jquery, but i don't know how to call theHttp.Post Users/FindUserByFirstLetterName(string letter) on the click event.
I cannot use the Html.ActionLink<> helper, since it redirects me to the HttpGet controller action.
I also tried using using jqery.Post but i also couldn't manage to call the action.
i have a website where i provicde a link. On clicking the link a controller action method is called to generate a zip file after creation of zip file is done, i show the link to download the zip file by replacing the link to create a zip with the link to download the zip.
the problem is that after zip file creation is over and link is shown, when user clicks on the link to download the zip file, they are sent to login. After providing correct credentials in the login page they are prompted to download the zip file. they sould not be sent to the login page. In the action to generate zip file i haven't abondoned the session or haven't not done anything that abondons the session.
the user should not be sen't to login page after successful creation of zip file user should be able to download the file without login. i search internet on this problem, but i did not find any solution. In one of the blog written by hanselman i found this statement that creates the problem with the session: Is some other thing like an Ajax call or IE's Content Advisor simultaneously hitting the default page or login page and causing a race condition that calls Session.Abandon? (It's happened before!)
so i thought there might be some problem with ajax call that causes the session to expire, but i don't know what is happening? it's like this after users click on the link to create zip file the zip file is created successfully but the session gets expired. this is not what i want. Why does the session has to get expired after making a jquery post call to controller action to create a zip file? i hope u understand the problem.
I'm trying to add file upload functionality to a page. I've got a form that posts the selected file to a controller with a 'savefile' method. But if I don't add a get version of 'savefile' I'll get a 404 error. Here is the form code which is presented on the Index page:
[Code]....
And here is the controller code:
[Code]....
Intuitively I don't think I should need a GET version of SaveFile but if omit it I get a 404 error when the form posts. Why should I need a GET version of SaveFile when all I want is to post a form and save the file?
I am using asp.net mvc 1.0. In this I have to create an UI for modifying the profile of the user. Now this modfiy profile will contain jquery tabs. and each jqeury tab will show some results such as user's personel information, professional info, etc on seperate tabs. I also want to give user ability to modify the fields and save this modified data. I am just not getting any idea how to do that. I have searched on internet for various jquery examples. most of them are just showing data to user by creating some partial views. Also i am not getting exactly how this functionality can be achieved through ajax on click of button.
In Short: Does any know a way from the base controller to get a list of actionFilters being applied to the current executing action?
The Long:I am using ASP.NET MVC 1.0 framework. I have a "RequireSSL" actionFilter that I've recreated for checking out, however, if someone leaves the checkout and goes back to the store I would like to forward them back to non-secure version of the site.It would be helpful in the base controller (I am using a custom base controller that inherits from the default Controller) to find out what actionFilters are being applied to the current action.I could include this into the global.asax.cs
I have asp.net mvc application. i want to configure the object in jquery and want to pass it to the the action of controller . where as in my script i am using this for configure data for the ajax call:
[Code]....
it does not calls to action in controller. i think here :
var json = $.toJSON(peform);
is not working as expect. is it need to add any js file to reference ? or mistake in syntax?
i would like to call an HttpGet GetEvents(Datetime dateSelected) controller action each time the user cliks on a date in jquery ui datepicker. I handle the onSelect datepicker event in order to call GetEvents() and refresh the Events page with the events for the selected date. The $.ajax method i use from jquery hits the GetEvents action, but instead of refreshing the page (and the url), i get an ajax result back.
[Code]....
So, how could i just call the HttpGet GetEvents() controller action via jquery, without the use of ajax in order to refresh the page?
Basically, I have an HTML Form and would want to pass the data from the form to n asp.net mvc controller, then the controller would return an XML for client side manipulation.
Here is my initial code:
[Code]....
When I run and debug, I get a message that says "attr(..) is null or not an object. I am still trying to learn web development using ASP.NET MVC.
I'm trying to use the jQuery.post() function to post an object to an action method, but for some reason the nested objects aren't initialised properly when they're received by the action method.
Here's my javascript code:
[Code]....
And my action method:
[Code]....
company.Id has a value of 10, but company.User.Id is 0. what I'm doing wrong? I've not named any properties incorrectly, by the way.
Using Microsoft built-in jquery files, when counting numbers of checked checkbox, the jquery-1.4.2.min.js cannot count the correct result ,however, the version jquery-1.3.2.min.js gives out the correct one, why?
$("#check").click(function () { var nameSports = new Array(); var i = 0; $('input[name=selector]:checked').each(function () { nameSports[i] = jQuery(this).val(); i += 1; }); if (loopCounter != 0) { alert(i); } }); <input type="checkbox" value="1" name="selector"> <input type="checkbox" value="2" name="selector"> <input type="checkbox" value="3" name="selector"> <a id="check">Check Items</a>
I am trying to save user feedback by using jquery to post to an action however i am getting the error message "Failed to load source for: http://www.something.com/feedback/savefeedback" this code works fine on localhost but not when put on my shared hosting, this doesnt just affect this query post but also at least one other.
below i have the route from the global.ascx, the action int the FeedBackController and the query that does the post.
routes.MapRoute( "FeedBack", // Route name "FeedBack/{action}", // URL with parameters [code]....
Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case).How would you test TestController.Foo? (either the first or second link)
My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing.The controller:
public class TestController : Controller { public ActionResult Foo()[code].....
I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
[Code]....
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.
So I have a form with a text area on it, and I need to post it. I can't encode it (as far as I know) client side, prior to submit, and it causes the yellow screen of death before reaching the HttpPost action handler.
I have a asp.net list box control in which i populate items using Jquery by using some code like .. $("#MylistBox").append("<option value='somevalue'>Someitem</option>
dynamically . but in code behind when i use MylistBox.Items is always showing Count 0 no matter how much items add.
could any body explain me how can i save state of two list boxes on post back i am using jQuery of this kind i dont know on what event what should i do or where can i save view state or how can i use hiddenField to persist the state of both list box
I have a search form on my site. I want to post the search term to my controller. I just have a question about [AcceptVerbs(HttpVerbs.Post)]. It seems to post the field name. Why can't I just get the value ?View:
[Code]....
Controller:
[Code]....
Result:
ViewData["SearchTerm"] contains the value : txtSearch=my search term
I originally have the question posted here, but I need as many eyes as possible on it.Essentially, I'm having issues redirecting to an action in mvc2 when working with JSON data. I post a stringified JSON object to an action and the action in turn redirects as needed. It worked previously when using form fields, but not when I'm posting JSON. To get posted JSON objects to properly bind to parameters objects in MVC, I'm taking advantage of the JsonValueProviderFactory class from MVC2Futures/MVC3Beta.Why is this occuring? The jQuery ajax call is telling the server "I'm giving you json, I expect html in return" and all actions pointed to via RedirectToAction calls are structured in a similar manner. I instead get stuck in a loop, continually hitting the originally requested action, with a prompt to reenter authorization information to boot! It seems lose authentication/authorization information in the process.The linked question on
I have a Person class with an Address property. The Address contains a Country property of type Country which in turn has a CountryCode property of type string, as follows:
Person.Address.Country.CountryCode
I have a select element on the page with a name of "Country.CountryCode". With MVC 1 this was bound perfectly to the CountryCode property of Country. In MVC 2 however, I get the following error when the page is posted back:
So I have a number of dropdown select list controls populated as part of a repeater. They might contain overlapping data, meaning that the first d d list control will have selections:
a b c
Second one:
c d e
Third one:
d e h
and so on.
So what I would like to do is to srart removing the duplicate items from the reset of drop down controls once the user starts selecting those. I intend to use jQuery for this.
