  • Returning the html from .ajax call

    - by coffeeaddict
    I'm getting undefined for some reason when I try to return the html via the callback function: function getDataFromUrl(urlWithContent) { // jQuery async request $.ajax( { url: urlWithContent, dataType: "html", success: function(data) { return $('.result').html(data); }, error: function(e) { alert('Error: ' + e); } }); } I know I'm getting data back, I see it in firebug in the response and also when I alert out the data, I see the entire page content come up in the alert box. When I call my function, I am doing the following: var divContent = getDataFromUrl(dialogDiv.attr("href")); if(divContent) dialogDiv.innerHTML = divContent; when I alert out the divContent (before the if statement) I'm getting undefined. Maybe I'm just going about this wrong on how I'm returning back the data? I also tried just return data; same thing, I get undefined after the call to this method when set to my variable.

  • Adding a Third Table to a Two-Table Join Query

    - by John
    Hello, The query below works just fine. It pulls fields from two MySQL tables, "comment" and "login". It does this for rows where "username" in the table "login" equals the variable "$profile." It also pulls fields for rows where "loginid" in the table "comment" equals the "loginid" that is also being pulled from "login." I would like to pull data from a third table called "submission," which has the following fields: submissionid loginid title url displayurl datesubmitted I would like to pull fields from rows in "submission" where "loginid" equals the "loginid" that is already being pulled from the other two tables, "login" and "comment." How can I do this? Thanks in advance, John Query: $sqlStrc = "SELECT l.username, l.loginid, c.loginid, c.commentid, c.submissionid, c.comment, c.datecommented FROM comment AS c INNER JOIN login AS l ON c.loginid = l.loginid WHERE l.username = '$profile' ORDER BY c.datecommented DESC LIMIT 10";

  • MVC Model Binding to a collection where collection does not begin with a 0 index

    - by FloatLeft
    I'm trying to perform remote validation on a property of an item within a collection. The validation works OK on the first item of the collection. The http request to the validation method looks like: /Validation/IsImeiAvailable?ImeiGadgets[0].ImeiNumber=123456789012345 However on the 2nd item where the url looks like below, the validation doesn't work /Validation/IsImeiAvailable?ImeiGadgets[1].ImeiNumber=123456789012345 Now I'm pretty sure the reason for this, is that binding wont work on a collection that doesn't begin with a zero index. My validation method has a signature as below: public JsonResult IsImeiAvailable([Bind(Prefix = "ImeiGadgets")] Models.ViewModels.ImeiGadget[] imeiGadget) Because I'm passing an item within a collection I have to bind like this yet what I'm really passing is just a single value. Is there anyway I can deal with this other than just binding it as a plain old query string. Thanks Edit: This is the quick fix to get the Imei variable but I'd rather use the model binding: string imeiNumber = Request.Url.AbsoluteUri.Substring(Request.Url.AbsoluteUri.IndexOf("=")+1);

  • sfConfig::get is not returning constants defined in app.yml

    - by morpheous
    I have an interesting problem. I am using Symfony 1.3.2. I have defined some constants in project/apps/frontend/config/app.yml and project/config/app.yml When I use the constant (correct spelling) in a piece of code like this $test=sfConfig::get('app_foobar'); the variable $test is assigned a null value. This is what I have checked so far: CHECK: cache files generated? (YES) CHECK: Do the cache files (config_app.yml.php) in the cache directory contain the constants defined in the app.yml file (YES) CHECK: Constant names used in the code matches the array keys found in config_app.yml? (YES) At this stage, I have run out of ideas. I dont want to supply a default value as a hack, because when I need to change the value of the constant, I will have to replace this in potentially hundreds of instances (too error prone). Is there anything that I have missed?. What could be causing this?

  • Getting a unix timestamp as a string in C++

    - by wyatt
    I'm using the function time() in order to get a timestamp in C++, but, after doing so, I need to convert it to a string. I can't use ctime, as I need the timestamp itself (in its 10 character format). Trouble is, I have no idea what form a time_t variable takes, so I don't know what I'm converting it from. cout handles it, so it must be a string of some description, but I have no idea what. If anyone could help me with this it'd be much appreciated, I'm completely stumped. Alternately, can you provide the output of ctime to a MySQL datetime field and have it interpreted correctly? I'd still appreciate an answer to the first part of my question for understanding's sake, but this would solve my problem.

  • Iterator category

    - by Knowing me knowing you
    In code: //I know that to get this effect (being able to use it with std algorithms) I can inherit like I did in line below: class Iterator //: public std::iterator<std::bidirectional_iterator_tag,T> { private: T** itData_; public: //BUT I WOULD LIKE TO BE ABLE TO DO IT BY HAND AS WELL typedef std::bidirectional_iterator_tag iterator_category; typedef T* value_type;//SHOULD IT BE T AS value_type or T*? typedef std::ptrdiff_t difference_type; typedef T** pointer;//SHOULD IT BE T* AS pointer or T**? typedef T*& reference;//SHOULD IT BE T& AS reference or T*&? }; Basically what I'm asking is if I have my variable of type T** in iterator class is it right assumption that value type for this iterator will be T* and so on as I described in comments in code, right next to relevant lines. Thank you.

  • How to extend abstract Entity class in RIA Services

    - by Calanus
    I want to add a bool variable and property to the base Entity class in my RIA services project so that it is available throughout all the entity objects but seem unable to work out how to do this. I know that adding properties to actual entities themselves is easy using .shared.cs and partial classes but adding such properties to the Entity class using similar methods doesn't work. For example, the following code doesn't work namespace System.ServiceModel.DomainServices.Client { public abstract partial class Entity { private bool auditRequired; public bool AuditRequired { get { return auditRequired; } set { auditRequired = value; } } } } All that happens is that the existing Entity class gets totally overriden rather than extending the Entity class. How do I extend the base Entity class so that functionality is available thoughout all derived entity classes?

  • Screen recorder for tracking back your steps while debugging?

    - by hstoerr
    I am wondering whether there is a screen recorder that is usable for checking what exactly you did a couple of minutes ago while debugging, or just checking what value for a variable was displayed the last time you hit that breakpoint etc. (Of course this latter question would be something terrific for an IDE to implement, but I've never seen something like that so far. :-) For this you would need a screen recorder that could record all day and preferably automatically delete the recording the recording that is, say, older than an hour. Probably the recording format should be something that is good for screen recording instead of natural scenes. Do you know a screen recorder like that or at least one that comes close?

  • Ruby w/ Postgres & Sinatra - Query won't order right with parameter??

    - by alleywayjack
    So I set a variable in my main ruby file that's handling all my post and get requests and then use ERB templates to actually show the pages. I pass the database handler itself into the erb templates, and then run a query in the template to get all (for this example) grants. In my main ruby file: grants_main_order = "id_num" get '/grants' do erb :grants, :locals => {:db=>db, :order=>grants_main_order, :message=>params[:message]} end In the erb template: db = locals[:db] getGrants = db.exec("SELECT * FROM grants ORDER BY $1", [locals[:order]]) This produces some very random ordering, however if I replace the $1 with id_num, it works as it should. Is this a typing issue? How can I fix this? Using string replacement with #{locals[:order]} also gives funky results.

  • CakePHP hasAndBelongsToMany (HABTM) Delete Joining Record

    - by Jason McCreary
    I have a HABTM relationship between Users and Locations. Both Models have the appropriate $hasAndBelongsToMany variable set. When I managing User Locations, I want to delete the association between the User and Location, but not the Location. Clearly this Location could belong to other users. I would expect the following code to delete just the join table record provided the HABTM associations, but it deleted both records. $this->Weather->deleteAll(array('Weather.id' => $this->data['weather_ids'], false); However, I am new to CakePHP, so I am sure I am missing something. I have tried setting cascade to false and changing the Model order with User, User-Weather, Weather-User. No luck. Thanks in advance for any help.

  • Objective-C NSString Assignment Problem

    - by golfromeo
    In my Cocoa application, in the header file, I declare a NSString ivar: NSString *gSdkPath; Then, in awakeFromNib, I assign it to a value: gSdkPath = @"hello"; Later, it's value is changed in the code: gSdkPath = [NSString stringWithString:[folderNames objectAtIndex:0]]; (the object returned from objectAtIndex is an NSString) However, after this point, in another method when I try to NSLog() (or do anything with) the gSdkPath variable, the app crashes. I'm sure this has something to do with memory management, but I'm beginning with Cocoa and not sure exactly how this all works. Thanks for any help in advance.

  • C++: Why don't I need to check if references are invalid/null?

    - by jbu
    Hi all, Reading http://www.cprogramming.com/tutorial/references.html, it says: In general, references should always be valid because you must always initialize a reference. This means that barring some bizarre circumstances (see below), you can be certain that using a reference is just like using a plain old non-reference variable. You don't need to check to make sure that a reference isn't pointing to NULL, and you won't get bitten by an uninitialized reference that you forgot to allocate memory for. My question is how do I know that the object's memory hasn't been freed/deleted AFTER you've initialized the reference. What it comes down to is that I can't take this advice on faith and I need a better explanation. Can anyone shed some light? Thanks, jbu
