  • jquery: How to deal with 'this' in ajax callbacks

    - by Svish
    I currently have code similar to this for a form: $('#some-form') .submit(function() { // Make sure we are not already busy if($(this).data('busy')) return false; $(this).data('busy', true); // Do post $.post("some/url", $(this).serialize(), function(data) { if(data.success) // Success is a boolean I set in the result on the server { // Deal with data } else { // Display error } $('#some-form') .removeData('busy'); }); return false; }); My issue is that I would like to somehow remove the need for knowing the form id in the post callback. In the end where I remove the busy data from the form, I'd like to somehow not have that hard coded. Is there any way I can do this? Is there a way I can hand whatever is in this to the post callback function? Since I know the id right now, I can get around it by doing what I have done, but I'd like to know how to not be dependant on knowing the id, since often I don't have an id. (For example if I have a link in each row in a table and all the rows have the same click handler.

  • Excel: VLOOKUP that returns true or false?

    - by Svish
    In Excel we have the VLOOKUP function that looks for a value in a column in a table and then returns a value from a given column in that table if it finds something. If it doesn't, it produces an error. Is there a function that just returns true or false depending on if the value was found in a column or not?

  • How to do REST with PUT and DELETE

    - by Svish
    It says about the type option of the jQuery.ajax() method that The type of request to make ("POST" or "GET"), default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers. So... Does that mean that PUT and DELETE won't work if the browser does not support it, or just that PUT and DELETE can not be done natively by the user in the browser? If I can't or shouldn't use those, what do people usually do instead? Send the method as a a GET or POST parameter instead? Or?

  • jQuery: How to use modifier keys on form submit?

    - by Svish
    Say I have a form that looks like this: [ Animal name input field ] Add button If I type a name and hit enter, an animal with the given name is added to a table. Works fine. What I would like now is to call the current way of working "quick add" and add a new feature called "slow add", which I am not quite sure how to do. Basically what I want is that if for example the shift key is held down when enter or the button is clicked, I want the form submit method to do something slightly different. In my case I want it to open up a form where more details on the animal can be added before it is added to the table. Problem is I'm not quite sure how to do this. I have tried add a FireBug console.info(eventData) in my current submit function and I have found that the eventData contains an altKey, shiftKey and controlKey property, but they are always undefined even when I hold those keys down. So, does anyone know how I can do something special in my submit handler when certain modifier keys were pressed when the form was submitted?

  • MySQL: How to check if a string is a valid DATE, TIME or DATETIME

    - by Svish
    When I try to put a value into a DATE field which is invalid, MySQL seems to use 0000-00-00 instead. Is there a way I can do this "check" without updating a DATE field? And to do it from for example PHP? Like, is there a way I can query the MySQL server and ask "Hey, is this DATE, TIME or DATETIME valid to you?" Or is there maybe an even better way of doing it?

  • CSS: Base styles on body or html?

    - by Svish
    When I declare some base styles for my site I have used to do that on the body tag. Like for example body { font-size: medium; line-height: 1.3em; } But I have also seen people do things like that on the html tag. And on both. Where should it be done? Should some be at one and some at the other? Should all be on one of them? Or does it simply not matter at all? Or?

  • PHP: Adding arrays together

    - by Svish
    Could someone help me explain this? I have two snippets of code, one works as I expect, but the other does not. This works $a = array('a' => 1, 'b' => 2); $b = array('c' => 3); $c = $a + $b; print_r($c); // Output Array ( [a] => 1 [b] => 2 [c] => 3 ) This does not $a = array('a', 'b'); $b = array('c'); $c = $a + $b; print_r($c); // Output Array ( [a] => 1 [b] => 2 ) What is going on here?? Why doesn't the second version also add the two arrays together? What have I misunderstood? What should I be doing instead? Or is it a bug in PHP?

  • C#: How to implement a smart cache

    - by Svish
    I have some places where implementing some sort of cache might be useful. For example in cases of doing resource lookups based on custom strings, finding names of properties using reflection, or to have only one PropertyChangedEventArgs per property name. A simple example of the last one: public static class Cache { private static Dictionary<string, PropertyChangedEventArgs> cache; static Cache() { cache = new Dictionary<string, PropertyChangedEventArgs>(); } public static PropertyChangedEventArgs GetPropertyChangedEventArgsa(string propertyName) { if (cache.ContainsKey(propertyName)) return cache[propertyName]; return cache[propertyName] = new PropertyChangedEventArgs(propertyName); } } But, will this work well? For example if we had a whole load of different propertyNames, that would mean we would end up with a huge cache sitting there never being garbage collected or anything. I'm imagining if what is cached are larger values and if the application is a long-running one, this might end up as kind of a problem... or what do you think? How should a good cache be implemented? Is this one good enough for most purposes? Any examples of some nice cache implementations that are not too hard to understand or way too complex to implement?

  • Mercurial: Recommended way of sending a whole repository to someone

    - by Svish
    I have done some programming and I have used Mercurial for source control. I now need to send all of my code to someone else (because they are going to take over). Since all copies of a mercurial repository is a full and real repository my first thought is to first do a clone of my repository without an update and then zipping and emailing that clone. Is this a good way, or is there a better way? For example when using the TortoiseHg Repository Explorer I can right-click on a changeset and under Export there are various options that looks like they could be doing something interesting, but I don't quite understand them or know which one to use.

  • MySQL: List rows who have one but not another many-to-many relationship

    - by Svish
    Not quite sure how to ask or define this, but can't figure it out. I have three tables like this: persons person_id, first_name, last_name hobbies hobby_id, name persons_hobbies person_id, hobby_id I need to make two lists. Persons that have both hobby A and B, and persons that have hobby A but not B. How can I write these two queries? Can't figure out how to do this with joining and all...

  • C#: Resource file refactoring

    - by Svish
    Does anyone know of a good tool for refactoring resources in a visual studio 2008 solution? We have a number of resource files with translated text in an assembly used for localizing our application. But they have gotten a bit messy... I would like to rename some of the keys, and move some of them into other resource files. And I would like those changes be done in my code, and the translated versions of the resource files as well. Maybe a some analysis on what strings are missing in the translated versions, and what strings have been removed from the original as well... Does anyone know of a good visual studio extension or ReSharper plugin that can help me with this? Right now it is kind of a pain, because I have to first rename the key in the base resource file, then in the localized versions. And then compile to get all the compile errors resulting from the key which now have a different name, and then go through and fix them all... very annoying =/
