  • CSS "and" and "or"

    - by Misiur
    Hi there. I've got quite big trouble, because i need to anathematise from styling some input types. I had something like: .registration_form_right input:not([type="radio") { //Nah. } But i don't want to style checkboxes too. I've tried: .registration_form_right input:not([type="radio" && type="checkbox"]) .registration_form_right input:not([type="radio" && "checkbox"]) .registration_form_right input:not([type="radio") && .registration_form_right input:not(type="checkbox"]) How to use &&? And I'll need to use || soon, and I think that usage will be same. Thanks.

    - by emilolsson
    Hello I'm trying to be able to check if a selector have a certain sets of classes. .hasClass() can only check if the selector has one class. And the .is() selector can look for multiple classes but will return true if the selector have at least one of the classes. But I wan't to achieve a way to check if a selector have both of the classes, and only if it has both of the classes do action. Any pointers?

    If I have two tables; Drivers keyed by DriverId and Trips with foreign keys DriverId and CoDriverId, and I want to find all trips where a driver was either the driver or co-driver I could code this in Transact-SQL as select d.DriverId, t.TripId from Trips t inner join Drivers d on t.DriverId = d.DriverId or t.CoDriverId = d.DriverId How could this be coded as a LINQ query?

  • Listview...how to conditionally replace a value with a string

    - by GaryAmundson
    Hi, my app presents a listview, from a database cursor and XML, that needs to replace the values in a column with various words based on the integer value contained in the cursor. For example, if the value is -1, replace it with the word "Invalid", but if the value is = 0 then just display the value. I was under the impression this could magically be done via XML... TIA.

  • How to understand "if ( obj.length === +obj.length )" Javascript condition statement?

    - by humanityANDpeace
    I have run across a condition statement which I have some difficulties to understand. It looks like (please note the +-sign on the right-hand-side) this: obj.length === +obj.length. Can this condition and its purpose/syntax be explained? Looking at the statement (without knowing it) provokes the impression that it is a dirty hack of some sort, but I am almost certain that underscore.js is rather a well designed library, so there must be a better explanation. Background I found this statement used in some functions of the underscore.js library (underscore.js annotated source). My guesswork is that this condition statement is somehow related to testing for a variable obj to be of Array type? (but I am totally unsure). I have tried to test this using this code. var myArray = [1,2,3]; testResult1 = myArray.length === +myArray.length; console.log( testResult1 ); //prints true var myObject = { foo : "somestring", bar : 123 }; testResult2 = myObject.length === +myObject.length; console.log( testResult2 ); //prints false

  • Adding items to dictionary if condition is true, else dont - python

    - by CodeTalk
    I'm trying to take an existing process: if self.path_object is not None: dictpath = {} for path in self.path_object: self.params = path.pathval.split("?")[0] self.params = path.pathval.split("&", 2) if path.pathval.contains(self.params): out = list(map(lambda v: v.split("=")[0] +"=" + str(self.fuzz_vectors), self.params)) else: pass dictpath[path] = out print dictpath I added the sub-if/else block in, but it is failing, stating: AttributeError: 'unicode' object has no attribute 'contains' on the if block . How can I fix it? I'm simply trying to do: if the path.pathval has either ? or & in it: add to dictionary else: pass #forget about it. Thanks!

  • MYSQL inserting records form table A into tables B and C (linked by foreign key) depending on column values in table A

    - by Chez
    Hi All, Have been searching high and low for a simple solution to a mysql insert problem. The problem is as follows: I am putting together an organisational database consisting of departments and desks. A department may or may not have n number of desks. Both departments and desks have their own table linked by a foreign key in desks to the relevant record in departments (i.e. the pk). I have a temporary table which I use to place all new department data (n records long)...In this table n number of desk records for a department follow the department record directly below. In the TEMP table, if a column department_name has a value,it is a department, if it doesn't it will have a value for the column desk and therefore will be a desk which is related to the above department. As I said there maybe several desk records until you get to the next department record. Ok, so what I want to do is the following: Insert the departments into the departments table and its desks into the desks table , generating a foreign key in the desk record to the relevant departments id. In pseudo-ish code: for each record in TEMP table if Department INSERT the record into Departments get the id of the newly created Department record and store it somewhere else if Desk INSERT the desk into the desks table with the relevant departments id as the foreignkey note once again that all departments desks directly follow the department in the TEMP Table Many Thanks

  • Shuffling a list with a constraint

    - by 500
    Preparing a new psychophysic experiment, I have 48 original stimuli displayed 4 times (4 conditions). Resulting in 192 trials. Trying to randomize the order of presentation during the experiment, I need to maximize the distance between the 4 display of the same original stimuli. Please Consider : Table[{j, i}, {j, Range[48]}, {i, Range[4]}] Where j is the original stimuli number and i the condition Output Sample : {{1, 1}, {1, 2}, {1, 3}, {1, 4}, {2, 1}, {2, 2}, {2, 3}, {2, 4}, ... {47, 1}, {47, 2}, {47, 3},{47, 4}, {48, 1}, {48, 2}, {48, 3}, {48, 4}} How could I shuffle the order of presentation of those 192 items, maximizing the distance between identical item with regard to j the original stimuli number ?

  • conditionally enabling constructor

    - by MK
    Here is how I can conditionally enable a constructor of a class : struct Foo { template<class T> Foo( T* ptr, boost::enable_if<is_arithmetic<T> >::type* = NULL ) {} }; I would like to know why I need to do the enabling via a dummy parameter. Why can I not just write : struct Foo { template<class T> Foo( boost::enable_if<is_arithmetic<T>, T>::type* = NULL ) {} };

  • How to check if my string is equal to null?

    - by Roman
    I want to perform some action ONLY IF my string has a meaningful value. So, I tried this. if (!myString.eqauls("")) { doSomething } and this if (!myString.eqauls(null)) { doSomething } and this if ( (!myString.eqauls("")) && (!myString.eqauls(null))) { doSomething } and this if ( (!myString.eqauls("")) && (myString!=null)) { doSomething } and this if ( myString.length()>0) { doSomething } And in all cases my program doSomething in spite on the fact that my string IS EMPTY. It equals to null. So, what is wrong with that?

  • Rails - Create if record doesn't exist or else update.....Whats Best way to do this?

    - by ChrisWesAllen
    Hi, I have a create statement for some models but its creating a record within a join table regardless if the record exist. Here is what my code looks like. @user = User.find(current_user) @event = Event.find(params[:id]) for interest in @event.interests @user.choices.create(:interest => interest, :score => 4) end The problem is it creates records no matter what. I would like it to create a record if it doesnt exist, if a record does exist I would just to it to take the attribute of the found record and add or subtract 1. So, I've been looking around and I see something called find_or_create_by. My question is what happens if it finds? Preferably if it finds,I would like to take the current :score attribute and +1. SO is it possible to find or create by id? I'm not sure what attribute I would find by since the model I'm looking at is a join model which only had id foreign keys and the score attribute. I tried @user.choices.find_or_create_by_user(:user => @user.id, :interest => interest, :score => 4) but got "undefined method `find_by_user'".....ANy ideas or help?

  • jQuery UI: how to run evaluation

    - by mikkelbreum
    I want to add 'Year' or Years' to the end of a string depending on the string. Like this: $("#selector").val(conditional_value_here); Using jQuery UI I have a slider that manipulates a value: $("#slider").slider({ value: 1, min: 1, max: 25, step: 1, slide: function(event, ui) { $("#amount").val(ui.value + ' Year' + function(){return (ui.value == 1) ? '' : 's';} ); } }); // and again I want to do the same for the initialization of the value: $("#amount_3").val($("#slider_3").slider("value") + ' Jahr' + function(){return ($("#slider_3").slider("value") == 1) ? '' : 's';}); This does not work. What is the correct way to to this?

  • validates_associated not honoring :if

    - by James Ferguson
    I'm totally blocked on this. See this pastie for sample code: http://pastie.org/990040 The first test will fail. The user model validates an associated address model, but is only supposed to do it if a flag is true. In practice it does it all the time. What is going on?

  • switch vs. if...else if...else

    - by John Hartsock
    Guys I have a couple of questions: Is there a preformance difference in Javascript between a switch statement and an if...else if....else? If so why? Is the behavior of switch and if...else if...else different across browsers? (FireFox, IE, Chrome, Opera, Safari) The reason for asking this question is it seems that I get better preformance on a switch statement with approx 100 cases in Firefox. But in IE it get better preformance with 100 if...else if...else.

  • Child sProc cannot reference a Local temp table created in parent sProc

    - by John Galt
    On our production SQL2000 instance, we have a database with hundreds of stored procedures, many of which use a technique of creating a #TEMP table "early" on in the code and then various inner stored procedures get EXECUTEd by this parent sProc. In SQL2000, the inner or "child" sProc have no problem INSERTing into #TEMP or SELECTing data from #TEMP. In short, I assume they can all refer to this #TEMP because they use the same connection. In testing with SQL2008, I find 2 manifestations of different behavior. First, at design time, the new "intellisense" feature is complaining in Management Studio EDIT of the child sProc that #TEMP is an "invalid object name". But worse is that at execution time, the invoked parent sProc fails inside the nested child sProc. Someone suggested that the solution is to change to ##TEMP which is apparently a global temporary table which can be referenced from different connections. That seems too drastic a proposal both from the amount of work to chase down all the problem spots as well as possible/probable nasty effects when these sProcs are invoked from web applications (i.e. multiuser issues). Is this indeed a change in behavior in SQL2005 or SQL2008 regarding #TEMP (local temp tables)? We skipped 2005 but I'd like to learn more precisely why this is occuring before I go off and try to hack out the needed fixes. Thanks.
