  • Best way to manage JSON object via GET and POST in php.

    - by Kucebe
    My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'JSON_Obj' : myJSON_Obj }. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['JSON_Obj'] or $_POST['JSON_Obj']. For example, using file_get_contents("php://input"), i can manage POST requests in that way, but in GET format it doesn't work. Any suggestions?

  • How can I declare an object with properties that I will be passing around inside of my function using Typescript?

    - by Marilou
    I've been using the following: var modal = { content: '', form: '', href: '' } But now I have started to use Typescript is there a better way I can declare an object and how can I declare the types of my properties. The reason I am using this object is that it's inside of a function and inside that function I have other functions that set and use the values of the properties. Is this the best way for me to do this or is there another way I could better do this with typescript?

  • Where is a good javascript reference for object event handlers?

    - by GregH
    I am relatively new to Javascript and constantly need to look up how to handle various events for objects. For example, I have a table containing a few text fields and need to know when somebody starts typing in any of the text boxes. Is there any good concise reference on the web anyplace that documents all of the objects and event handlers associated with all objects? I'd like to be able to look up the object and see all of the events I can handle for that object.

  • Can you get a Func<T> (or similar) from a MethodInfo object?

    - by Dan Tao
    I realize that, generally speaking, there are performance implications of using reflection. (I myself am not a fan of reflection at all, actually; this is a purely academic question.) Suppose there exists some class that looks like this: public class MyClass { public string GetName() { return "My Name"; } } Bear with me here. I know that if I have an instance of MyClass called x, I can call x.GetName(). Furthermore, I could set a Func<string> variable to x.GetName. Now here's my question. Let's say I don't know the above class is called MyClass; I've got some object, x, but I have no idea what it is. I could check to see if that object has a GetName method by doing this: MethodInfo getName = x.GetType().GetMethod("GetName"); Suppose getName is not null. Then couldn't I furthermore check if getName.ReturnType == typeof(string) and getName.GetParameters().Length == 0, and at this point, wouldn't I be quite certain that the method represented by my getName object could definitely be cast to a Func<string>, somehow? I realize there's a MethodInfo.Invoke, and I also realize I could always create a Func<string> like: Func<string> getNameFunc = () => getName.Invoke(x, null); I guess what I'm asking is if there's any way to go from a MethodInfo object to the actual method it represents, incurring the performance cost of reflection in the process, but after that point being able to call the method directly (via, e.g., a Func<string> or something similar) without a performance penalty. What I'm envisioning might look something like this: // obviously this would throw an exception if GetActualInstanceMethod returned // something that couldn't be cast to a Func<string> Func<string> getNameFunc = (Func<string>)getName.GetActualInstanceMethod(x); (I realize that doesn't exist; I'm wondering if there's anything like it.) If what I'm asking doesn't make sense, or if I'm being unclear, I'll be happy to attempt to clarify.

  • JQuery UI: is it possible to know where an object has been dropped?

    - by Jack Duluoz
    Hi, what I want to do is to know where (not in terms of position (x, y), but a reference to the DOM element) an object was dropped. I have a grid made up with divs where you can drop various items and I need to know which div on the grid was the item dropped on (getting its id would be fine). The callback function function(event, ui) { //code here } has just that ui object who doesn't apparently contain any information about this, but only about the draggable item or its helper.

  • Fill business object from database by calling stored procedurs?

    - by grady
    Hello, I have several stored procedures in my database, some of them have params, some have no params. I tried to fill a business object by calling the stored procedures, but failed so far. How could I do that dynamically? Later, I want to use this object as a datasource for a report...but thats the next step. The important facts are: different stored procs return different amount of columns stored procs can have params, but its not required How could I achieve that? Thanks :)

  • In Ruby, how to write a method to display any object's instance variable names and its values

    - by Jian Lin
    Given any object in Ruby (on Rails), how can I write a method so that it will display that object's instance variable names and its values, like this: @x: 1 @y: 2 @link_to_point: #<Point:0x10031b298 @y=20, @x=38> I also want to be able to print <br> to the end of each instance variable's value so as to print them out nicely on a webpage. the difficulty now seems to be that not every instance variable has an accessor, so it can't be called with obj.send(var_name) (the var_name has the "@" removed, so "@x" becomes "x")

  • <object> pasted into textarea is removed... why?

    - by swt83
    I have a textarea that saves data into a database. For some reason it is removing <object> tags from anything that I paste into it -- none of the other tags are removed, only <object> tags. I've never had this problem before and have done this same thing in times past -- any ideas as to what could cause this? I'm not filtering the data before it's saved to the db at all.

  • Adding object to child collection causes entire collection to load in Fluent NHibernate.

    - by Mike C.
    Hello, I have my Parent object, which contains an ICollection of Children objects. The Children are lazy loaded and I do not need them in the context of my scenario. However, when I try to add a new child object to my Children collection, it kicks off the lazy load and loads all 7000 child records. I assume I am making a newbie mistake. Anybody out there know how I can fix this? Thanks!

  • Where to store the session object in a Standalone application?

    - by HanuAthena
    I'm having a session object that does NOT implement the java.lang.Serializable. (its a legacy application, and now I can't go and change the code) Is there any way where I can store the session object some where and later GET BACK THE SAME STATE in a STANDALONE application. One thought is to use RMI. Is there any better way of achieving this. Thank you :)
