Note: the way the functions prepend() and css() are used in this script is called 'chaining'.
Chaining is optional; the same could be achieved by storing the result of the query in a
variable:
var box = query("#box");
box.prepend("<p>Peter Parker</p>");
box.css("color","red");
remove()
Removes each element in a set from the DOM.
This function returns a new result set containing each removed element. These can be
changed and inserted in the document. This could be beneficial in terms of performance, as
manipulating elements inside the DOM is relatively time consuming.
Examples
This script removes all Span elements found in the template.
results.remove();
