If you want to add an attribute to some element you can use the attr(attributeName, attributeValue) function. For example: $('a').attr('title', 'Click me'); This example will add mouseover text "Click me" to all links on the page. The same function is used to change attributes' values...

$q is a built-in service which helps in executing asynchronous functions and using their return values(or exception) when they are finished with processing. $q is integrated with the $rootScope.Scope model observation mechanism, which means faster propagation of resolution or rejection into your m...

(.) lets us compose two functions, feeding output of one as an input to the other: (f . g) x = f (g x) For example, if we want to square the successor of an input number, we can write ((^2) . succ) 1 -- 4 There is also (<<<) which is an alias to (.). So, (+ 1) <<&lt...

Control.Category defines (>>>), which, when specialized to functions, is -- (>>>) :: Category cat => cat a b -> cat b c -> cat a c -- (>>>) :: (->) a b -> (->) b c -> (->) a c -- (>>>) :: (a -> b) -> (b -> c) -> (a -> c...

The angular.identity function returns the first argument passed to it. angular.identity(argument) This function is useful for functional programming, you can provide this function as a default in case an expected function was not passed. Examples: angular.identity(42) // 42 var mutate = f...

The angular.forEach accepts an object and an iterator function. It then runs the iterator function over each enumerable property/value of the object. This function also works on arrays. Like the JS version of Array.prototype.forEach The function does not iterate over inherited properties (prototype...

Transform tr = GetComponent<Transform>().Find("NameOfTheObject"); GameObject go = tr.gameObject; Find returns null if none is found ProsConsLimited, well defined search scopeStrings are weak references

#include <stdio.h> #include <threads.h> #include <stdlib.h> struct my_thread_data { double factor; }; int my_thread_func(void* a) { struct my_thread_data* d = a; // do something with d printf("we found %g\n", d->factor); // return an succes...

ALTER TABLE fish_data.fish DROP PRIMARY KEY; ALTER TABLE fish_data.fish MODIFY COLUMN fish_id DECIMAL(20,0) NOT NULL PRIMARY KEY; An attempt to modify the type of this column without first dropping the primary key would result in an error.

In Insert mode, press <C-r> and then % to insert the filename. This technique is applicable to all registers. For e.g. if in insert mode, you want to paste the current search pattern, you can type <C-r> and then /.

Fold Right successively applies a two-argument function to every element in a list from left to right starting with a base value: foldr: (a b -> b) b (listof a) -> b > (foldr + 0 (list 1 2 3 4)) 10 > (foldr string-append "" (list "h" "e" "l&quot...

When the first time view is requested, normally Angular makes XHR request to get that view. For mid-size projects, the view count can be significant and it can slow down the application responsiveness. The good practice is to pre-load all the views at once for small and mid size projects. For large...

Sometimes it's useful to be able to extend a class with new functions. For example let's suppose that a string should be converted to a camel case string. So we need to tell TypeScript, that String contains a function called toCamelCase, which returns a string. interface String { toCamelCase()...

While running any web application it’s necessary to take loading time into consideration. If your code tries to access any element that is not yet loaded, WebDriver will throw an exception and your script will stop. There are three types of Waits - Implicit Waits Explicit Waits Fluent Waits ...

In explicit wait, you expect for a condition to happen. For example you want to wait until an element is clickable. Here is a demonstration of a few common problems. Please note: In all of these examples you can use any By as a locator, such as classname, xpath, link text, tag name or cssSelector ...

In Racket, we use recursion very frequently. Here is an example of a function that sums all of the numbers from zero to the parameter, n. (define (sum n) (if (zero? n) 0 (+ n (sum (sub1 n))))) Note that there are many helpful convenience based functions used here, such as ...

The following example shows the declaration of a property (StringProperty in this case) and demonstrates how to add a ChangeListener to it. import java.text.MessageFormat; import javafx.beans.property.SimpleStringProperty; import javafx.beans.property.StringProperty; import javafx.beans.value.Ch...

This example shows how to use a readonly wrapper property to create a property that cannot be written to. In this case cost and price can be modified, but profit will always be price - cost. import java.text.MessageFormat; import javafx.beans.property.IntegerProperty; import javafx.beans.property...

Mostly used under ng-repeat ngValue is useful when dynamically generating lists of radio buttons using ngRepeat <script> angular.module('valueExample', []) .controller('ExampleController', ['$scope', function($scope) { $scope.names = ['pizza', 'unicorns', 'robots']; ...

Overall the easiest way to work with JSON is to have a case class mapping directly to the JSON (same fields name, equivalent types, etc.). case class Person( name: String, age: Int, hobbies: Seq[String], pet: Pet ) case class Pet( name: String, `type`: String ) // these...
