The eq( index ) method reduces the set of matched elements to a single element.
Here is the simple syntax to use this method:
selector.eq( index ) |
Here is the description of all the parameters used by this method:
index: This is the position of the element in the set of matched elements, starting at 0 and going to length - 1.
Following is a simple example which adds the color to second list item.
<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() { $("li").eq(2).addClass("selected"); }); </script> <style> .selected { color:red; } </style> </head> <body> <div> <ul> <li>list item 1</li> <li>list item 2</li> <li>list item 3</li> <li>list item 4</li> <li>list item 5</li> <li>list item 6</li> </ul> </div> </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() { $("li").eq(2).addClass("selected"); }); </script> <style> .selected { color:red; } </style> </head> <body> <div> <ul> <li>list item 1</li> <li>list item 2</li> <li class="selected">list item 3</li> <li>list item 4</li> <li>list item 5</li> <li>list item 6</li> </ul> </div> </body> </html> |
