before()
Insert content before each element in the set of HTML elements that match the of the script or of another query in the template (see query()). See also: after().
before(content)
Before(content) inserts content before each element in the set of elements that match the script's selector.
Before() creates a new result set.
content
String, HTML string or result set to insert after the elements. In case a plain text string is provided, it is
automatically wrapped in a <span> element to avoid orphan
text nodes to appear in the <body> element.
Examples

|
#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");
The following script searches the results for the string "ipsum" and puts "Lorem " before it. "Lorem " is automatically wrapped in a Span element. results.find("ipsum").before("Lorem ");
| Matched element |
Matched element after script execution |
| <p>ipsum dolor sit amet, consectetur adipiscing elit.</p> |
<p><span>Lorem </span>ipsum dolor sit amet, consectetur adipiscing elit.</p>
|
The following script looks for an element with the ID salesrep and inserts the text "Lorem Ipsum" before that element. "Lorem Ipsum" is automatically wrapped in a Span element. query("#salesrep").before("Lorem Ipsum");
| Matched element |
Matched element after script execution |
| <p>ipsum dolor sit amet, consectetur adipiscing elit.</p> |
