In an 'Each matched element' script you would first need to check the return value of this.prev
():
var prevSibling = this.prev();
if prevSibling != null { prevSibling.css("font-weight", "bold"); }
remove()
Removes the current element or 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();

adipiscing elit.</p>
The selector of the following sample script is tbody. Before this script runs, the table body
consists of a single placeholder row with three cells. After running the script, it contains thirty
rows. To improve performance, most of the DOM manipulation takes place on detached
elements.
// Detach the placeholder row from the DOM
var row = query("tr", results).remove();
