Examples
This script looks for an element with the ID salesrepand inserts a paragraph before that
element.
results.before("<p>Lorem Ipsum</p>");
Selector Matched element Matched element after script
execution
#salesrep
<p id="salesrep">Peter
Parker</p>
<p>Lorem ipsum</p>
<p id="salesrep">Peter Parker</p>
This script does the same, but it uses the query() function to look up the element.
query("#salesrep").before("<p>Lorem ipsum</p>");
Matched element Matched element after script execution
<p id="salesrep">Peter Parker</p> <p>Lorem ipsum</p>
<p id="salesrep">Peter Parker</p>
The following script looks for an element with the ID salesrep, inserts a paragraph before that
element and colors that element red.
query("#salesrep").before("<p>Lorem ipsum</p>").css("color","red");
Matched element Matched element after script execution
<p id="salesrep">Peter Parker</p> <p >Lorem ipsum</p>
<p id="salesrep"style="color: red;">Peter Parker</p>
Note: the way the functions before() 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 salesrep = query("#salesrep");
salesrep.before("<p>Lorem ipsum</p>");
salesrep.css("color","red");
