forms

问题 I'm afraid I'm not seeing it yet. There must be a way, using the tools as they are intended to be used, to get the ID of a child record (many-to-one typical relational database stuff) of a series of "items" I can create a "form" (mapping) in the case class of the parent no problem. lazy val aForm = Form( mapping( "ID" -> ignored(id), "firstName" -> nonEmptyText, "lastName" -> nonEmptyText, "listOfEmails" -> seq(email), "statusID" -> ignored(0l), "roleID" -> default(longNumber, roleID),

问题 How do i cut,copy,paste from main menu in a multi textboxes form ? How does the menu knows to apply on the active textbox ? 回答1: Please see this article here on Codeproject that does the job in synchronizing each text box's "standard" edit menu such as Copy, Cut, Paste, Undo, Select All. Of course, the code originally targets the .NET 1.1, but it can be easily recompiled to target the newer frameworks as well. 回答2: In the menu click event you can examine this.ActiveControl to see what control

问题 I have a simple form with a select menu on the node display page. Is there an easy way to validate the form in my callback function? By validation I don't mean anything advanced, just to check that the values actually existed in the form array. For example, without ajax, if my select menu has 3 items and I add a 4th item and try to submit the form, drupal will give an error saying something similar to "an illegal choice was made, please contact the admin." With ajax this 4th item you created

In this case region I have thought about using another label.querySelectorAll("option"); But i don't know how to just get the top one. Current JS: var labels = document.querySelectorAll("label"); var i = labels.length; while (i--) { var label = labels.item(i); var text = label

问题 The title is actually a failed attempt to achieve my goal. Specifically, I want to 1. Go to a page from main.html (say, to page1.html). 2. Collect data in a form on page1. 3. On Submit, go to page2.html (which saves data to database using PHP and announces result). 4. Click on "Ok" and go back to main menu page. Seems reasonable, right? Step 4 above is my problem. Things I've tried: 1. Invoke history.back on Ok click in page2. This goes to page1 not main 2. Invoke javascript location.href

问题 a couple of days ago, I posted here and got a great response on how to handle the arrays. This was exactly what I needed foreach ($_POST['name'] as $key=>$name) { echo "Name: $name Age: {$_POST['age'][$key]}"; } the problem is, I need it not to print but to persist.

I need access to

问题 I am attempting a fairly simple form on Django 1.3, and am trying to understand how CSRF works. I think I've followed the three steps detailed on the Django site, but am still unable to make the form work. The form displays when the URL is loaded, however upon hitting the submit button, I get the following error: TypeError at /txt/ txt() takes exactly 1 argument (2 given) Here's the actual code: views.py: from django.http import HttpResponse from django.shortcuts import render_to_response,
