• Finding the FORM that an element belongs to in JavaScript

  - by Magnus Smith

  How can I find out which FORM an HTML element is contained within, using a simple/small bit of JavaScript? In the example below, if I have already got hold of the SPAN called 'message', how can I easily get to the FORM element? <form name="whatever"> <div> <span id="message"></span> </div> </form> The SPAN might be nested within other tables or DIVs, but it seems too long-winded to iterate around .parentElement and work my way up the tree. Is there a simpler and shorter way? If it wasn't a SPAN, but an INPUT element, would that be easier? Do they have a property which points back to the containing FORM? Google says no...

• WinForms form freezes

  - by andrew

  On a form (F1) i have a button, from which if i create another form (lets call it F2) and show it there's no problem but i'd like to do something like this Some thread in my app is running a connection and listens for messages from a server. when a message arrives, my main form is registered to get an event that runs a function. From that function i'm trying to create and show the F2 type form (empty, nothing modified in it): it shows it but then it freezes my application. more exactly: public partial class Form1 : Form { public Form1() { InitializeComponent(); ConnectionManagerThread.getResponseListener().MessageReceived += Form1_OnMessageReceived; } private void Form1_OnMessageReceived(object sender, MessageEventArgs e) { Form2 f2 = new Form2(); f2.Show(); } }

• Django Passing Custom Form Parameters to Formset

  - by Paolo Bergantino

  I have a Django Form that looks like this: class ServiceForm(forms.Form): option = forms.ModelChoiceField(queryset=ServiceOption.objects.none()) rate = forms.DecimalField(widget=custom_widgets.SmallField()) units = forms.IntegerField(min_value=1, widget=custom_widgets.SmallField()) def __init__(self, *args, **kwargs): affiliate = kwargs.pop('affiliate') super(ServiceForm, self).__init__(*args, **kwargs) self.fields["option"].queryset = ServiceOption.objects.filter(affiliate=affiliate) I call this form with something like this: form = ServiceForm(affiliate=request.affiliate) Where request.affiliate is the logged in user. This works as intended. My problem is that I now want to turn this single form into a formset. What I can't figure out is how I can pass the affiliate information to the individual forms when creating the formset. According to the docs to make a formset out of this I need to do something like this: ServiceFormSet = forms.formsets.formset_factory(ServiceForm, extra=3) And then I need to create it like this: formset = ServiceFormSet() Now how can I pass affiliate=request.affiliate to the individual forms this way?

• How to add css to form elements if attribute class is already being used in Jquery

  - by Gublooo

  Hey guys This is probably a dumb question - I'm using Jquery to validate the form. So the form elements have the class="required" attribute. input type="text" name="last_name" class="required"/ Now if i want to apply some css properties to the input fields of this form - how do I do that. I do not want to declare a general css for all input elements - I have declared the css as follows: input.form { color: #000; background: #fff; border: 2px solid #E1E1E1; font-size: 16pt; width:150px; } And I want to use it this way input class="form" type="text" name="last_name" class="required"/ But this wont work as there are two class attributes here. So how do I handle this. Thanks

• Close box triggers validation for non-modal form

  - by Governor

  I have two form classes inheriting from a common base. One of the forms is called modally and the other non-modally. Validation is required on focus changes but not when the form is cancelled. When the Close Box is selected on the modal form it closes properly without any validation being triggered on it's controls. When the Close Box is selected on the non-modal form, validation events are triggered. A Cancel button with CausesValidation set false works fine in both cases. I have tried setting CausesValidation on the non-modal form to false but the problem remains. I should mention that the forms are mdi children. Any ideas? Thx.

• Can't seem to get Prototype AJAX form validation to work in conjunction with Codeigniter

  - by MattB

  Is there some kind of trick involved? Here's how I would envision it working: 1) User tries submitting the form 2) Event.observe captures this and sends an AJAX request to a special validation URL (PHP using Codeigniter) 3) If no errors were returned, continue submitting the original form 4) If errors were found, cancel form submission and display Mostly, I can't seem to get a separate AJAX validation request to work as the form continues submitting. I could use Event.stop(event), but have not found a way to re-start the process if no validation errors exist from the validation call. I'd post code, but I have about 15 examples of things I've tried and it would just clutter this question. Any ideas? :-( I didn't think form validation would be this difficult. Many thanks, - Matt

• Django: Geocoding an address on form submission?

  - by User

  Trying to wrap my head around django forms and the django way of doing things. I want to create a basic web form that allows a user to input an address and have that address geocoded and saved to a database. I created a Location model: class Location(models.Model): address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100, null=True) postal_code = models.CharField(max_length=100, null=True) country = models.CharField(max_length=100) latitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) longitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) And defined a form: class LocationForm(forms.ModelForm): class Meta: model = models.Location exclude = ('latitude','longitude') In my view I'm using form.save() to save the form. This works and saves an address to the database. I created a module to geocode an address. I'm not sure what the django way of doing things is, but I guess in my view, before I save the form, I need to geocode the address and set the lat and long. How do I set the latitude and longitude before saving?

• How to override form just on one page?

  - by user363036

  OK so this is my hook form alter function.It is causing all the registration forms on site to be over written which I do not want as I just want it on this page. function special_registration_form_alter(&$form, $form_state, $form_id) { if ($form_id == 'user_register') { drupal_set_title(t('Custom registration')); $form['firstname'] = array('#type' = 'textfield', '#title' = t('First Name: *'), '#required' = TRUE, '#size' = 45, '#weight' = - 100,); $form['lastname'] = array('#type' = 'textfield', '#title' = t('Last Name: *'), '#required' = TRUE, '#size' = 45, '#weight' = - 99,); } I only first name and last name to be captured and stored in a different table just on this page. On other pages I just want the good old fashioned form. Do I still need to change the weight? I know I am missing something elementary.

• Apache HttpClient making multipart form post

  - by Russ

  I'm pretty green to HttpClient and I'm finding the lack of (and or blatantly incorrect) documentation extremely frustrating. I'm trying to implement the following post (listed below) with Apache Http Client, but have no idea how to actually do it. I'm going to bury myself in documentation for the next week, but perhaps more experienced HttpClient coders could get me an answer sooner.

  Thanks for checking out my problem... I'm having trouble submitting a login form via Ajax for a php script to run and return a new set of html items which will be replacing the HTML in #userlinks.... heres what I have so far $("#login_form").submit(function() { return false; }); $('#login_button').click(function(event) { $form = $(this).parent("form"); $.post($form.attr("action"), $form.serialize(), function(data){ $('#userlinks').html(data); }); }); The php script checks for post data of username && password, yet all I'm getting is a page refresh and no changes.

  - by George

  In the following example, I have a link that sends a variable to a function which checks if the variable is true and, if so, submits a form on the page. This has been tested and works in IE, Safari, and Chrome, but not Firefox. Trying to figure out what's wrong in Firefox.

• How can I access form elements when using an ASP.NET MVC Ajax form?

  - by Patrick

  I've got an ajax form in an MVC 2 application. I cannot find the proper way to access the form elements within the Ajax form decleration. I can access the name of the elements with Request.Form.Keys but I can't access the actual values. I've read numerous examples of posting forms with jQuery but my form has elements created dynamically based on route values (sometimes it could be 2 text boxes sometimes 10, given unique names like so: <%= Html.TextBox("Evaluation"+Model.EvaluationId.ToString())) so I couldn't find a way to make that work with jQuery. Is there another way that I for elements can be accessed?

• Method of getting text on a windows form ( unmanaged C++ project )

  - by Donovan

  I'm in the process of learning C++. I've created a boilerplate Win32 app within VC++ 2008. I've studied through the code and am ready do do a bit of experimenting. I thought it would be cool to print all the windows messages received in the message loop to the form created via the boilerplate code. I for the life of me, can't figure out the method of getting text onto that form. I can't seem to identify and named object that I can use to reference that damn form. The best I can figure is I need to use the handle to reference the form somehow. Still, even if I did know how to reference the form, I'm not sure I know how I would create a label to display the text. Anyway, if someone could just point out what methodology I need to learn to make this happen it would be much appreciated. Thanks, Donovan

• vb.net add text to form without interaction

  - by user228058

  I have a winform project which lists all the files in a specified folder. It allows the user to select a new destination for each file, and when the user has chosen the destinations for all files that he would like to be moved, it moves the files, one by one. My next step is, I need to display a confirm form when the files are being moved, and add each file's name and destination to the confirm form as it is being moved. My question is: How can I add more text to the confirm form's controls after I already loaded it (using confirm.showdialog() from my other form, without any user interaction? I imagine that I need to do it from the original form, because it needs to display each one when it starts to move that file, but I'm open to any suggestions:) TIA

• jQuery append breaks my HTML form (with submit button)

  - by JimFing

  I'm trying to create a form with a submit button via jQuery using append(). So the following: out.append('<form name="input" action="/createuser" method="get">'); out.append('Username: <input type="text" name="user" />'); out.append('<input type="submit" value="Submit" />'); out.append('</form>'); However, clicking on submit, nothing happens! However if I do the following: var s = '<form name="input" action="/createuser" method="get">' + 'Username: <input type="text" name="user" />' + '<input type="submit" value="Submit" />' + '</form>'; out.html(s); Then the submit button works fine! I'm happy to use the 2nd method, but would rather know what the problem is here. Thanks
