closest(selector)
For each element in a set, this function gets the first element that matches the selector by
testing the element itself and traversing up through its ancestors in the DOM tree.
selector
A String containing an HTML tag (without the angle brackets, <>).
Examples
The following script looks up all table rows in the template that contain an <input> element.
query("input").closest("tr");
This code gets the closest 'parent' row for each element that matches the selector of the script
(collected in the results object):
results.closest("tr");
The rows could be colored red within the same statement:
results.closest("tr").css('background-color','red');
css()
Gets the value of a style property for the first element in the set of HTML elements that match
the selector of the script or of another query in the template (see "query()" on page1158), or
sets one or more CSS properties for every element in the set.
css(styleName) : String
Returns the value of the specified CSS property.
propertyName
String; the name of the CSS property.
Examples
This script stores the text color of the results (the HTML elements that match the selector of the
script) in a variable.
var textcolor = results.css("color");
