Note: the way the functions add() and css() are used in this script is called 'chaining'. Chaining
is optional; the same could be achieved by storing the results of the queries in a variable:
var myResult = query("#test1");
myResult.add(query("#test2");
myResult.css("background", "yellow");
Creating an empty result set and adding elements to it
The following script loads snippets in an iteration and adds their elements to an empty result
set (using query()). Then it replaces a placeholder in the template with the new result.
var chapters = query();
for ( var i = 1; i <= 4; i++) {
chapters = chapters.add(loadhtml('snippets/Chapter' + i +
'.html'));
}
results.replaceWith(chapters);
Selector Matched element Matched element after script
execution
#chapters <p id="chapters">
{{chapters}}</p>
<h1>Chapter 1</h1>
<p>Lorem ipsum...</p>
<h1>Chapter 2</h1>
<p>Loremipsum...</p>
<h1>Chapter 3</h1>
<p>Loremipsum...</p>
<h1>Chapter 4</h1>
<p>Loremipsum...</p>
