An element can be removed by calling remove() on it. Alternatively, one can call removeChild() on its parent. removeChild() has better browser support than remove().
element.remove();
element, and all its childnodes, are removed from the DOM.
parentElement.removeChild(element);

A bit field is a variable that holds various boolean states as individual bits. A bit on would represent true, and off would be false. In the past bit fields were routinely used as they saved memory and reduced processing load. Though the need to use bit field is no longer so important they do offer...
Template Haskell is enabled by the -XTemplateHaskell GHC extension. This extension enables all the syntactic features further detailed in this section. The full details on Template Haskell are given by the user guide.
Splices
A splice is a new syntactic entity enabled by Template Haskell, writ...
Less doesn't put any restrictions on the number of times the parent selector (&) can be used in a complex selector and so, we can use it more than once like in the below examples to select sibling elements without the need to repeat the selector.
.demo {
border: 1px solid black; /* add borde...
Function calls as f(a) always imply a sequence point between the evaluation of the arguments and the designator (here f and a) and the actual call. If two such calls are unsequenced, the two function calls are indeterminately sequenced, that is, one is executed before the other, and order is unspeci...
The first substatement of an if statement may be followed by the keyword else. The substatement after the else keyword will be executed when the condition is falsey (that is, when the first substatement is not executed).
int x;
std::cin >> x;
if (x%2 == 0) {
std::cout << "Th...
Examples of using functions with hotkeys:
Hotkey, a, MyFunction ; Calls MyFunction() when a is pressed
MyFunction() {
MsgBox You pressed %A_ThisHotkey%.
}
Or:
a::MyFunction()
MyFunction() {
MsgBox You pressed %A_ThisHotkey%.
}
I'll demonstrate the basic usage of using functions vs using labels+gosub.
In this example we'll implement simple functionality to add two numbers and store them in a variable.
With functions:
c := Add(3, 2) ; function call
MsgBox, Result: %c%
Add(a, b) { ; This is a function. Put it wherever...
The following code is taken from he official AutoHotkey documentation:
Function implementation:
#Persistent
OnClipboardChange("ClipChanged")
return
ClipChanged(Type) {
ToolTip Clipboard data type: %Type%
Sleep 1000
ToolTip ; Turn off the tip.
}
Label implementati...
This script demonstrates how to receive complicated GUI events from different controls in the same event callback function. We'll be using two ListView controls for that.
Now every time an action is detected on one of those ListView controls, we want a precise description of what happened and have ...
This is a very simple program to create a PDF using iText 7 / Java:
//Initialize writer
PdfWriter writer = new PdfWriter(dest);
//Initialize document
PdfDocument pdfDoc = new PdfDocument(writer);
Document doc = new Document(pdfDoc);
//Add paragraph to the document
doc.add(new Paragraph(&q...
With IpRateLimit middleware you can set multiple limits for different scenarios like allowing an IP or IP range to make a maximum number of calls in a time interval like per second, 15 minutes, etc. You can define these limits to address all requests made to an API or you can scope the limits to eac...
With ClientRateLimit middleware you can set multiple limits for different scenarios like allowing a Client to make a maximum number of calls in a time interval like per second, 15 minutes, etc. You can define these limits to address all requests made to an API or you can scope the limits to each URL...
In modern browsers [1], it is possible to use CSS-like selector to query for elements in a document -- the same way as sizzle.js (used by jQuery).
querySelector
Returns the first Element in the document that matches the query. If there is no match, returns null.
// gets the element whose id="...

Inserting elements is simple:
> let m = Map.singleton "Alex" 31
fromList [("Alex",31)]
> Map.insert "Bob" 99 m
fromList [("Alex",31),("Bob",99)]
