How to select a range of elements in jQuery

<div id="myDiv"> <a>...</a> <a>...</a> <a>...</a> <a>...</a> <a>...</a> <a>...</a> </div>

If you want to select tags 2, 3 and 4 a in the above example, how do you do it? The only thing I can think of:

 $("#myDiv a:eq(1), #myDiv a:eq(2), #myDiv a:eq(3)")

But it does not look very effective or beautiful. I think you could also select ALL a and then execute .each on it, but this can become very inefficient if there was a lot more than a s.

The jQuery slice () function, which uses the indices of the first and last required elements, selects a subset of the matched elements. Please note that it does not include the last item.

In your particular case you should use

 $("#myDiv a").slice(1, 4)

Use . The slice () function does exactly what I need.

You must do this by extracting a slice of the array in this way. This is a string

 $("div[id='myDiv'] > a").slice(1,4).css("background","yellow");

which interests you. This will affect the 2nd, 3rd and 4th elements.

 <html> <head> <script type="text/javascript" src="jquery-1.2.6.pack.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("a").click(function(event){ $("div[id='myDiv'] > a").slice(1,4).css("background","yellow"); event.preventDefault(); }); }); </script> </head> <body> <div id="myDiv"> <a>1</a> <a>2</a> <a>3</a> <a>4</a> <a>5</a> <a>6</a> </div> <hr> <a href="" >Click here</a> <hr> </body> </html>
