The prev( [selector] ) method gets the immediately preceding sibling of each element in the set of matched elements, optionally filtered by a selector.
Here is the simple syntax to use this method:
selector.prev( [selector] ) |
Here is the description of all the parameters used by this method:
selector: This is optional selector to filter the previous Elements with.
Following is a simple example a simple showing the usage of this method. Try this example without passing selector in prev() method:
<html> <head> <title>the title</title> <script type="text/javascript" src="/jquery/jquery-1.3.2.min.js"></script> <script type="text/javascript" language="javascript"> $(document).ready(function(){ $("p").prev(".selected").addClass("hilight"); }); </script> <style> .hilight { background:yellow; } </style> </head> <body> <div><span>Hello</span></div> <p class="selected">Hello Again</p> <p>And Again</p> </body> </html> |
This would generate following result.
<html> <head> <title>the title</title> <script type="text/javascript" src="/jquery/jquery-1.3.2.min.js"></script> <script type="text/javascript" language="javascript"> $(document).ready(function(){ $("p").next(".selected").addClass("hilight"); }); </script> <style> .hilight { background:yellow; } </style> </head> <body> <div><span>Hello</span></div> <p class="hilight">Hello Again</p> <p>And Again</p> </body> </html> |
