  • It's possible to don't pass in GET some fields of a form?

    - by avastreg
    I have a form with some input texts passed in GET, and i don't want to have in GET all the fields; i want to avoid empty fields. So, a concrete example for: <form method="GET" action="an_url"> <input type="text" name="field1"/> <input type="text" name="field2"/> <input type="text" name="field3"/> <input type="submit" value="submit"/> </form> I supposed that fields disabled by html attribute "disabled" shouldn't be passed to GET. So i have done a js (based on jquery) to disable empty fields on submit, something like this: $("form").submit(function() { $(this).find("input[type=text]").each( function () { if (!$.trim($(this).val())) { $(this).attr("disabled", "true"); } }); }); However, this doesn't work. Any ideas?

  • Why does this IF statement fail?

    - by ChosenOne
    If variable path is empty, and editor.Text is not empty, the SaveFileDialog should be displayed. Now, why on earth is this damn thing failing??? I have tried this with many different variations of code with the same result: FAIL: if(path.Length >= 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } At the top of code file I have: path = String.Empty; So why the heck it this failing every single time, even after trying all of the below variations? if(path.Length > 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrEmpty(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrWhiteSpace(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } This is making me very angry. How could this fail? Setting a break point reveals that path is definitely null/"".

  • Casting to generic type in Java doesn't raise ClassCastException?

    - by Kip
    I have come across a strange behavior of Java that seems like a bug. Is it? Casting an Object to a generic type (say, K) does not throw a ClassCastException even if the object is not an instance of K. Here is an example: import java.util.*; public final class Test { private static<K,V> void addToMap(Map<K,V> map, Object ... vals) { for(int i = 0; i < vals.length; i += 2) map.put((K)vals[i], (V)vals[i+1]); //Never throws ClassCastException! } public static void main(String[] args) { Map<String,Integer> m = new HashMap<String,Integer>(); addToMap(m, "hello", "world"); //No exception System.out.println(m.get("hello")); //Prints "world", which is NOT an Integer!! } }

  • "Strictly positive" in Agda

    - by Jason
    I'm trying to encode some denotational semantics into Agda based on a program I wrote in Haskell. data Value = FunVal (Value -> Value) | PriVal Int | ConVal Id [Value] | Error String In Agda, the direct translation would be; data Value : Set where FunVal : (Value -> Value) -> Value PriVal : N -> Value ConVal : String -> List Value -> Value Error : String -> Value but I get an error relating to the FunVal because; Value is not strictly positive, because it occurs to the left of an arrow in the type of the constructor FunVal in the definition of Value. What does this mean? Can I encode this in Agda? Am I going about it the wrong way? Thanks.

  • Configure vlan on Netgear switch via SNMP

  • AutoKey - clipboard.get_selection() function fails on certain strings

    - by LonnieBest
    I've simplified my script so you can focus on the essence my problem. In AutoKey (not AutoHotKey), I made a Hot-Key (shift-alt-T) that performs this script on any string I have highlighted (like in gedit for example -- but any other gui editor too). strSelectedText = clipboard.get_selection() keyboard.send_keys(" " + strSelectedText) The script modifies the highlighted text and adds a space to the beginning of the string. It works for most strings I highlight, but not this one: * Copyright © 2008–2012 Lonnie Best. Licensed under the MIT License. It works for this string: * Add a Space 2.0.1 but not on this one: * Add a Space 2.0.1 – At the python command prompt, it has no problem any of those strings, yet the clipboard.get_selection() function seems to get corrupted by them. I'm rather new to python scripting, so I'm not sure if this is an AutoKey bug, or if I'm missing some knowledge I should know about encoding/preparing strings in python. Please help. I'm doing this on Ubuntu 12.04: sudo apt-get install autokey-qt

  • Using LINQ to find a common prefix?

    - by Roger Lipscombe
    I've got two sequences: IEnumerable<string> x = new[] { "a", "b", "c" }; IEnumerable<string> y = new[] { "a", "b", "d", "e" }; I'd like to find the common prefix of these two sequences (i.e. "a", "b"). Is there a succinct way to do this in LINQ? Bear in mind that these aren't really IEnumerable<string>; they're IEnumerable<PathComponent>, where I have an implementation of IEqualityComparer<PathComponent>.

  • SQL syntax error

    Im using Microsoft SQL Server which I think is T-SQL or ANSI SQL. I want to search a database with a string. The matches that fit the begging of the string should come first then sort alphabetically. I.e. If the table contains FOO, BAR and RAP a search for the string 'R' should yield: RAP BAR In that order. Here is my attempt: SELECT Name FROM MyTable WHERE (Name LIKE '%' + @name + '%') ORDER BY (IF(Name LIKE @name + '%',1,0)) The error message is: "must declare scalar variable @name"

  • Django and ajax image file upload errors and csrf

    - by sharkfin
    I tried out Alex Kuhl's ajax script to upload images to Django 1.4. My first question is why I'm getting an empty page with firebug telling me I have two errors: fileuploader.js (line 4): syntax error <!DOCTYPE html> In my template html: qq is not defined var uploader = new qq.FileUploader( { Here is my entire html file for it: http://pastebin.com/NjbV5gMn This post suggests that either some script has 404'd or the src attribute is empty, which would cause the doctype error. But that doesn't seem to be the case here. As for why qq is not defined, I'm not sure what is wrong. Django can clearly find the fileuploader.js just fine from my static folder. My second question is why the ajax code uses {{ csrf_token }} instead of {% csrf_token %}. But if I use {% csrf_token %}, I get the firebug error: missing } after property list 'csrf_token': '<div style='display:none'<input type='hidden' name='csrfmiddlewaretoken' value='Cx0zFFak6OLgrHiAnFa3k4BPDmn4BgoT' /</div',

  • Oauth callback problem

    - by yogsma
    I am using OAuth with google data api. We have a portal only for authorized users. So when users are logged in and if they are accessing calendar page, they will be asked if they want to sync their calendars with google calendar. If yes, they will be redirected for authentication. Once user has granted access, google appends OAuth_Token to the callback URL. the callback URL was that of the page of calendar in portal. This url has its query string options encrypted. But when the redirection happens , it takes back to login page of url. url is like http://aaa.xyz.com/(encrypted part of query string) and after oauth_token is authorized, this url becomes http://aaa.xyz.com/(encrypted part of query string)&oauth_token. So the user sees the login page after redirection instead of original page. How should I handle this in code.

  • In OpenRasta is it possible to Pattern match multiple key/value pairs?

    - by Scott Littlewood
    Is it possible in OpenRasta to have a Uri pattern that allows for an array of values of the same key to be submitted and mapped to a handler method accepting an array of the query parameters. Example: Return all the contacts named Dave Smith from a collection. HTTP GET /contacts?filterBy=first&filterValue=Dave&filterBy=last&filterValue=Smith With a configuration of: What syntax would be best for the Uri string pattern matching? (Suggestions welcome) ResourceSpace.Has.ResourcesOfType<List<ContactResource>>() .AtUri("/contacts") .And.AtUri("/contacts?filterBy[]={filterBy}[]&filterValue[]={fv}[]") // Option 1 .And.AtUri("/contacts?filterBy={filterBy}[]&fv={fv}[]") // Option 2 Would map to a Handler method of: public object Get(params Filter[] filters) { /* create a Linq Expression based on the filters using dynamic linq query the repository using the Linq */ return Query.All<Contact>().Where(c => c.First == "Dave" && c.Last == "Smith").ToResource() } where Filter is defined by public class Filter { public string FilterBy { get; set; } public string FilterValue { get; set; } }

  • groovy closure parameters

    - by Don
    Hi, The following example of using the sendMail method provided by the grails mail plugin appears in this book. sendMail { to "[email protected]" subject "Registration Complete" body view:"/foo/bar", model:[user:new User()] } I understand that the code within {} is a closure that is passed to sendMail as a parameter. I also understand that to, subject and body are method calls. I'm trying to figure out what the code that implements the sendMail method would look like, and my best guess is something like this: MailService { String subject String recipient String view def model sendMail(closure) { closure.call() // Code to send the mail now that all the // various properties have been set } to(recipient) { this.recipient = recipient } subject(subject) { this.subject = subject; } body(view, model) { this.view = view this.model = model } } Is this reasonable, or am I missing something? In particular, are the methods invokedwithin the closure (to, subject, body), necessarily members of the same class as sendMail? Thanks, Don

  • How do I set a VB.Net ComboBox default value

    - by Mr Ed
    I can not locate the correct method to make the first item in a combo box visible. The app starts with an empty combo box. The user makes a radio box selection then clicks Go! (how original). The combo box is loaded via an LDAP query. All this is working just fine. The problem is the combo box still appears to the user to be empty. They must click the arrow to see the options. How do I make the first option 'visible' after the users clicks Go!? I thought it would be simple... Thanks, Ed
